It follows from the material and compound, wall thickness and geometry, initial moisture content and required target condition, as well as the process, process conditions and loading; wall thickness has a disproportionate effect. Only a time determined and validated on the specific part is reliable. Historically set times can be reviewed in the same way: they may prove appropriate, longer than necessary or, under today\u2019s conditions, too short.<\/p><\/aside><\/div><\/div><\/div><div class=\"cs-koerper\"><div class=\"cs-bahn cs-koerper__raster\"><aside class=\"cs-toc-leiste\" data-vorlage><nav class=\"cs-toc\" aria-labelledby=\"toc-titel-r\"><p class=\"cs-toc__titel\" id=\"toc-titel-r\">Contents<\/p><ol><li><a href=\"#five-inputs\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">01<\/span><span>Five inputs<\/span><\/a><\/li><li><a href=\"#wall-thickness-and-time\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">02<\/span><span>Wall thickness and time<\/span><\/a><\/li><li><a href=\"#material-and-flame-retardants\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">03<\/span><span>Material and flame retardants<\/span><\/a><\/li><li><a href=\"#process-and-time\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">04<\/span><span>Process and time<\/span><\/a><\/li><li><a href=\"#historical-process-times\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">05<\/span><span>Historical process times<\/span><\/a><\/li><li><a href=\"#function-critical-features\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">06<\/span><span>Function-critical features<\/span><\/a><\/li><li><a href=\"#reviewing-the-time\"><span class=\"cs-toc__nr\" aria-hidden=\"true\">07<\/span><span>Reviewing the time<\/span><\/a><\/li><li><a href=\"#conclusion\"><span class=\"cs-toc__nr\" aria-hidden=\"true\"><\/span><span>Conclusion<\/span><\/a><\/li><li><a href=\"#frequently-asked-questions\"><span class=\"cs-toc__nr\" aria-hidden=\"true\"><\/span><span>Frequently asked questions<\/span><\/a><\/li><li><a href=\"#sources\"><span class=\"cs-toc__nr\" aria-hidden=\"true\"><\/span><span>Sources<\/span><\/a><\/li><\/ol><p class=\"cs-toc__zusatz\">Questions about your part?<br><a data-cta=\"anfrage\" href=\"https:\/\/condisystems.com\/en\/enquire-now\">Send an enquiry<\/a><\/p><\/nav><\/aside><div class=\"cs-fluss\" id=\"artikel-text\"><p>The right conditioning time has two limits. It is too short if the part does not reach the required condition: dry PA6 and PA66 are less tough at room temperature and are more prone to brittle fracture under impact or assembly loads.<\/p><p>Once the required condition, including the safety margin, has been reliably reached, additional time generally brings the part no further benefit. Whether it does harm depends on the process. If the part is simply approaching equilibrium with a suitably chosen climate, its moisture content barely changes; at elevated process temperatures, however, post-mould shrinkage and warpage can increase with duration. If the moisture supply is above the target, the part can take up more moisture than intended, with consequences for dimensions and stiffness. In every case, the extra time ties up equipment, floor space and inventory.<\/p><p>In practice, this often raises a second question: is the time a plant has used for years actually the time needed? In our experience, many specifications were set once and not re-examined since. This article explains what the conditioning time depends on, how to determine it, and how to review and safeguard an existing process time.

How fast this happens is described by the diffusion coefficient; in polyamide it depends, among other things, on temperature and water content.<\/p><\/aside><p>The effect of wall thickness on the time is not linear. ISO\u00a062 evaluates water absorption with Fick\u2019s model of a flat plate whose surfaces are held at constant conditions, and in this model thickness appears squared. Applied to two walls, the model gives the following: a snap-fit hook one third as thick as the base would reach the same point in about one ninth of the time. A wall twice as thick would need roughly four times as long.<\/p><p>ISO\u00a01110 likewise sets the minimum times before the first weighing and between weighings of polyamide test specimens in proportion to the square of the specimen thickness. Real parts deviate from the model: edges, ribs and changing wall thicknesses, uneven initial moisture and conditions that change during the process \u2014 for example while the load heats up \u2014 all play a part. The direction of the effect remains the same.<\/p><figure class=\"cs-abb cs-breit\" id=\"abb-1\" data-grafikversion=\"P-01-V-01-d2\"><div class=\"cs-abb__flaeche\" data-bleed><svg class=\"cs-g g-kompakt\" viewbox=\"0 0 380 684\" role=\"img\" aria-labelledby=\"v01ken-t v01ken-d\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><title id=\"v01ken-t\">Schematic: a thin and a thick wall at three points in time; the thin one is largely shaded early on, the thick one even late only in a wide band near its surfaces<\/title><desc id=\"v01ken-d\">Two wall cross-sections at three points in time under the same conditions, with qualitative shading and no values: the thin wall is shaded throughout by the second point in time, while the thick wall shows only a wide band near its surfaces around a lighter core even at the third.

The second consequence of the model is less widely known: uptake slows down the closer it gets to this equilibrium. The first half of the possible water uptake is reached comparatively quickly, while the last few per cent take the longest.<\/p><p>Under ISO\u00a01110:2019, accelerated conditioning of polyamide test specimens is considered complete when three consecutive weighings lie within 0.1\u00a0%. The standard equates this with at least 95\u00a0% of the equilibrium value, not with \u201ccomplete\u201d, and states that further conditioning has no noticeable effect on the properties of the specimens. So even the test laboratory does not wait for the last remainder of uptake.<\/p><aside class=\"cs-beispiel\" data-hypothetisch><p class=\"cs-beispiel__titel\"><svg viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.8\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\"><rect x=\"5\" y=\"3.5\" width=\"14\" height=\"17\" rx=\"2\"\/><path d=\"M8.5 8h7M8.5 12h1.5M12 12h1.5M8.5 16h1.5M12 16h1.5\"\/><\/svg>Worked example \u2014 idealised model, not a prediction for any part.<\/p><p>For a flat plate with a constant diffusion coefficient and constant boundary conditions, you can calculate how long it takes to reach a given fraction of the final uptake. Taking the time to 50\u00a0% as one, the plate needs about four times as long to reach 90\u00a0%, just under six times as long to reach 95\u00a0% and about nine times as long to reach 99\u00a0%. Polyamide follows this model only approximately, because its diffusion coefficient depends on the water content. How strongly the slowdown towards the end affects a particular polyamide can therefore differ considerably from the model; times for a real part cannot be derived from it.<\/p><\/aside><p>Two practical consequences follow. If the target condition lies close to the equilibrium of the climate provided, every further step towards it becomes expensive, because the final steps take up a large share of the total time. A target that is justified by the function and lies below that equilibrium, on the other hand, can be reached considerably earlier. This is no licence to lower targets \u2014 but it explains why two specifications with similar-sounding targets can need very different times.<\/p><\/section><section class=\"cs-kapitel\" aria-labelledby=\"material-and-flame-retardants\"><div class=\"cs-kapitel__kopf\"><span class=\"cs-kapitel__nr\" aria-hidden=\"true\" data-vorlage>03<\/span><h2 class=\"cs-h2\" id=\"material-and-flame-retardants\">PA6, PA66 and compounds: additives shift both the target and the rate<\/h2><\/div><p>According to manufacturer information, unreinforced PA6 takes up more water than unreinforced PA66 in the same climate. It does not automatically follow that PA66 conditions faster or more slowly. Uptake capacity and uptake rate are different quantities: one describes how much water the material holds at equilibrium, the other how quickly it gets there.<\/p><p>Measurements on thin films of an unreinforced PA66 have shown that the diffusion coefficient rises with temperature and depends strongly on the water content above the glass transition temperature of the amorphous (disordered) regions. This is the temperature above which these regions are no longer hard and glassy but mobile; absorbed water lowers it. There is therefore no blanket rule that PA66 takes longer or shorter than PA6; it would depend on the grade, the climate and the target.<\/p><p>Glass fibres do not take up water themselves, but they count towards the mass. A moisture value referred to the whole part is therefore lower without the polymer matrix being any drier. Anyone who transfers a target value from an unreinforced to a reinforced grade can easily end up comparing two different quantities. Other additives, such as impact modifiers, also change the uptake behaviour.<\/p><h3 class=\"cs-h3\" id=\"flame-retardant-compounds-can-take-longer-but-this-is-not-a\">Flame-retardant compounds can take longer \u2014 but this is not a rule<\/h3><p>In our experience at Condisystems, certain flame-retardant polyamide compounds can need longer conditioning times than comparable grades without flame retardant. This does not apply to every flame retardant. For this article, we found no published study that directly compares the uptake rate of flame-retardant and non-flame-retardant polyamides.<\/p><p>Flame retardants are not a single substance. To our knowledge, very different systems are used in polyamide compounds \u2014 the finished blend of polymer, fibres and additives \u2014 including both halogenated and halogen-free systems, among them systems based on red phosphorus. The datasheet and the material designation show which system a grade contains: under ISO\u00a01043-4, flame retardants are identified by \u201cFR\u201d and a code number.<\/p><h3 class=\"cs-h3\" id=\"what-datasheets-show-about-flame-retardants-and-moisture-and\">What datasheets show about flame retardants and moisture \u2014 and what they do not<\/h3><p>A datasheet comparison from a single manufacturer shows that a flame-retardant grade can have a lower equilibrium value in the standard atmosphere 23\/50 (23\u00a0\u00b0C, 50\u00a0% relative humidity) than a comparable grade without flame retardant. Ultramid A3EG5 from BASF is a PA66 with 25\u00a0% glass fibre and no flame retardant (PA66-GF25; the 25\u00a0% is a mass fraction). For this grade, BASF gives an equilibrium moisture absorption in this atmosphere \u2014 listed in the datasheet as saturation \u2014 of 1.7 to 2.1\u00a0%. For the comparable grade with a flame retardant based on red phosphorus, Ultramid A3X2G5, it gives 1.4 to 1.7\u00a0%. Saturation in water at 23\u00a0\u00b0C is 5.7 to 6.3\u00a0% for both.<\/p><p>All of these are typical values, determined by a method similar to ISO\u00a062. They refer to the whole material, including glass fibres and flame retardant, not to the polymer matrix. ISO\u00a062 refers to the mass of the pre-dried test specimen; the datasheets do not state the exact basis. They are not values for parts.<\/p><p>The datasheets do not say whether the lower value is due to the flame retardant itself or to other differences in the formulation.

In practice, every assessment of conditioning time should start from the exact compound designation. The target value is set for the compound rather than carried over from the standard grade, and the conditioning time is determined on the flame-retardant part. If the compound changes \u2014 for example because of a change of supplier or a new fire-safety requirement \u2014 the existing time has to be reassessed.<\/p><\/section><section class=\"cs-kapitel\" aria-labelledby=\"process-and-time\"><div class=\"cs-kapitel__kopf\"><span class=\"cs-kapitel__nr\" aria-hidden=\"true\" data-vorlage>04<\/span><h2 class=\"cs-h2\" id=\"process-and-time\">Temperature, moisture supply and loading: how the process changes the conditioning time<\/h2><\/div><p>A process changes the conditioning time through two levers: temperature, which sets the rate of diffusion, and the moisture supply, which determines which equilibrium can be reached.

The equilibrium moisture content reached is close to that in the standard atmosphere 23\u00a0\u00b0C \/ 50\u00a0% RH. The standard justifies the method by the very slow rate of moisture uptake at room temperature. The principle is instructive: the raised temperature shortens the time, while limiting the relative humidity to 62\u00a0%, rather than using a near-saturated atmosphere, keeps the result close to equilibrium in the standard atmosphere.<\/p><p><strong>Scope:<\/strong> The standard prepares test specimens for reproducible material testing. It does not apply to grades with more than 2\u00a0% by mass of extractable constituents, and mechanical property values may differ slightly from those obtained after storage in the standard atmosphere. It is not a specification for conditioning production parts.<\/p><\/aside><p>More heat is nevertheless not a free pass. Heat can trigger post-mould shrinkage in polyamide \u2014 annealing makes deliberate use of this. Whether and how strongly conditioning at elevated temperature has this effect depends on temperature, duration and grade; warpage, the heat resistance of the part and how evenly the load is heated also come into play. Which temperature a part can tolerate is a question for the material and the geometry, not for the equipment.<\/p><p>The moisture supply works differently: it sets the upper limit. The equilibrium depends on the relative humidity and the polyamide grade. If this equilibrium lies above the target condition, time has to limit the result; if it lies below, the part will not reach the target however long it is conditioned.<\/p><p>Loading plays a part in every process. Densely packed bulk loads, parts in the middle of a mesh pallet box or covered surfaces do not necessarily receive the same moisture and temperature as parts at the edge. When setting the time, what counts is therefore the least favourable position in a real load, not a sample part stored on its own.<\/p><h3 class=\"cs-h3\" id=\"what-the-process-principles-mean-for-the-conditioning-time\">What the process principles mean for the conditioning time<\/h3><p>This overview considers process principles solely in terms of their effect on the conditioning time.

The third outcome is valuable too.<\/p><aside class=\"cs-beispiel\" data-hypothetisch><p class=\"cs-beispiel__titel\"><svg viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.8\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\"><rect x=\"5\" y=\"3.5\" width=\"14\" height=\"17\" rx=\"2\"\/><path d=\"M8.5 8h7M8.5 12h1.5M12 12h1.5M8.5 16h1.5M12 16h1.5\"\/><\/svg>Worked example \u2014 hypothetical, freely chosen figures.<\/p><p>A plastics processor has been conditioning a part for years according to an internal specification of 36 hours.

These features are often thinner-walled than the base and can therefore reach the required condition earlier under the same conditions. For a specific part, this is not automatically established; the way the feature is connected, its geometry and the process control all play a part.<\/p><p>In addition, the condition at the end of the process is not the condition at assembly: afterwards, excess surface moisture is released quickly, moisture evens out between the thin feature and the base, and it continues to be exchanged with the surroundings.

in five stages. If a shorter time does not meet all requirements reproducibly, the existing time remains valid. If even the existing time does not meet them, it is not sufficient: identify the cause and adjust the time or the process. Schematic flow diagram.<\/figcaption><\/figure><h3 class=\"cs-h3\" id=\"step-1-record-the-existing-specification-and-where-it-came-f\">Step 1: Record the existing specification and where it came from<\/h3><p>Record all the parameters used for conditioning today: duration, temperature, humidity, process, loading and the time between moulding and conditioning. Where the specification came from is just as important. An internal rule of thumb can be reviewed internally; a validated process specification approved by the customer, or a requirement in a drawing or specification, is binding and can only be changed through an agreed change.<\/p><h3 class=\"cs-h3\" id=\"step-2-define-the-requirements-for-the-whole-part-and-the-ac\">Step 2: Define the requirements for the whole part and the acceptance criteria<\/h3><p>Establish which functions the part has to perform during assembly and in service, and which material and customer requirements are binding. These are turned into measurable acceptance criteria \u2014 before the first trial. Anyone who sets the criteria only after seeing the results runs the risk of fitting them to the desired outcome.<\/p><h3 class=\"cs-h3\" id=\"step-3-identify-critical-features-test-locations-and-worst-c\">Step 3: Identify critical features, test locations and worst-case conditions<\/h3><p>Identify the features that are sensitive to too little or too much moisture, and the locations where measurements or tests will be made. This includes the least favourable permissible conditions in production \u2014 and which conditions these are depends on the target. Freshly moulded parts contain little water and, depending on the storage climate, can already take up moisture before conditioning. If a minimum condition has to be reached, the driest permissible initial condition is therefore usually decisive \u2014 for example after the shortest storage time or in a dry storage climate. If a maximum value has to be met, a wetter initial condition can be less favourable.<\/p><p>What has to be considered, then, are the actual permissible ranges of initial moisture content, storage time and storage climate \u2014 not simply the longest storage time. Added to this are the densest loading and the least favourable position in the load. At the same time, record which requirements on the rest of the part are to be tested as well.<\/p><h3 class=\"cs-h3\" id=\"step-4-plan-comparative-trials-with-graded-times\">Step 4: Plan comparative trials with graded times<\/h3><p>Several conditioning times are investigated under otherwise identical, documented conditions, with the existing time as the reference. How many steps make sense and where they lie depends on the part; there are no generally valid time steps. Sample size and evaluation are planned with quality assurance so that the result supports a decision.<\/p><p>If you do not want to tie up your own equipment capacity for this, the conditioning of the trial parts can also be outsourced as contract conditioning, on a project basis and in all four processes. Results from a different system, however, initially apply only to that system and that process.<\/p><h3 class=\"cs-h3\" id=\"step-5-check-the-results-against-the-acceptance-criteria\">Step 5: Check the results against the acceptance criteria<\/h3><p>Testing takes place at a defined point in time, ideally the time at which the requirement applies, often at assembly, because after the process the moisture evens out within the part and continues to be exchanged with the surroundings. Functional tests on the critical feature, dimensional checks on the base and moisture measurements are assessed together. What each measurement tells you is set out in the section <a href=\"\/en\/how-to-condition-polyamide#how-to-verify-successful-conditioning\">How to verify successful conditioning<\/a> of our guide.<\/p><h3 class=\"cs-h3\" id=\"step-6-safeguard-process-stability-and-robustness\">Step 6: Safeguard process stability and robustness<\/h3><p>A time that is sufficient once is not yet a production time. The result has to hold across material batches, the permissible variation in initial moisture content, changing loads and the variation of the equipment. The new time is therefore not set at the shortest step that passed, but with a justified margin above it.<\/p><h3 class=\"cs-h3\" id=\"step-7-validate-the-new-process-time-and-obtain-approval\">Step 7: Validate the new process time and obtain approval<\/h3><p>A shorter time only counts as suitable once it meets all requirements reproducibly and the necessary approvals are in place. Depending on the supply relationship, for example in the automotive supply chain, the customer has to be informed before the change is introduced or has to agree to it. Without this approval, the existing specification remains valid, even if the trials support a shorter time.<\/p><h3 class=\"cs-h3\" id=\"step-8-document-implement-and-monitor\">Step 8: Document, implement and monitor<\/h3><p>The new time is laid down together with all parameters, the trial documentation and the acceptance criteria. The first production batches are tested more closely, and afterwards to the defined extent. If the material, supplier, mould, geometry or process changes, the time is reassessed \u2014 following the same logic that led to the review.<\/p><div class=\"cs-checkliste cs-breit\"><p class=\"cs-checkliste__titel\">Checklist: documents you should have ready to review a conditioning time<\/p><ul><li>current specification with all parameters, and where it came from<\/li><li>material with manufacturer, grade designation, fillers and flame retardant<\/li><li>drawing with wall thicknesses and function-critical features<\/li><li>binding customer and material requirements, existing process approvals<\/li><li>acceptance criteria and test methods<\/li><li>storage time and storage climate before conditioning<\/li><li>loading, batch size and time available<\/li><li>existing test results and known problems<\/li><\/ul><\/div><\/section><section class=\"cs-kontakt cs-breit\" aria-labelledby=\"how-long-will-your-parts-need-to-be-conditioned\"><div class=\"cs-kontakt__text\"><h2 class=\"cs-h2\" id=\"how-long-will-your-parts-need-to-be-conditioned\">How long will your parts need to be conditioned?<\/h2><p>We can discuss with you how the conditioning time for your parts can be estimated from material and part data, which process is suitable and how an existing process time can be reviewed.

Conditioning time scales with the square of wall thickness in the diffusion model, and uptake slows down as it approaches equilibrium. Even a change to the target, the wall or the compound can therefore shift the required time considerably.<\/p><p>An existing process time deserves the same scrutiny. It is a decision of its time, not proof of the shortest sufficient duration. Reviewing it can free up capacity and reduce lead time and inventory \u2014 or reveal that it is no longer sufficient under today\u2019s conditions. Either result is only reliable with trials, evidence of robustness and approval; the new time is then set with a margin above the shortest step that passed.<\/p><aside class=\"cs-merksatz\"><span class=\"cs-merksatz__label\">Key point<\/span><p>As long as technically necessary, but no longer than needed \u2014 based on verified part requirements and a validated process.<\/p><\/aside><\/section><section class=\"cs-kapitel cs-kapitel--faq\" aria-labelledby=\"frequently-asked-questions\"><div class=\"cs-kapitel__kopf\"><h2 class=\"cs-h2\" id=\"frequently-asked-questions\">Frequently asked questions<\/h2><\/div><div class=\"cs-faq\"><details class=\"cs-faq__eintrag\" id=\"does-pa66-need-different-conditioning-times-from-pa6\"><summary class=\"cs-faq__frage\"><span class=\"cs-faq__text\">Does PA66 need different conditioning times from PA6?<\/span><svg viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\"><path d=\"M6 9l6 6 6-6\"\/><\/svg><\/summary><div class=\"cs-faq__antwort\"><p>A time determined for PA6 does not automatically apply to PA66, but in which direction and by how much it differs cannot be stated in general terms.

The values refer to the whole material, not to the matrix, and whether this applies to flame retardants in general is an open question.
