The PV 1200 is intended to assess the behavior of the test parts with changes in temperature and humidity, for example with regard to crack formation, deformation, detachment. It serves as a short-term test with a time-lapse effect.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Heat and cold storage, temperature change test and their effects on materials<\/h2>\n\n\n\n<p>Polymer materials are subjected to a wide variety of conditions in a wide variety of applications. Since the properties of plastics are highly temperature-dependent and even low temperatures can lead to noticeable aging, it is important to check how the operating temperature affects the material selected for a specific application over a certain period of time.<\/p>\n\n\n\n<p>Polymer materials are subject to aging, which can often be attributed to the effects of temperature. Tensions in the plastic, e.g. under the influence of heat, lead to a distortion of the component (deformation) and thus to problems with the accuracy of fit within an assembly.<\/p>\n\n\n\n<p>If you want to determine aging values, the challenge is to keep the test duration as short as possible and still obtain meaningful results.<br>Particularly in the case of frequently changing temperatures as a result of temperature change tests, for example in metals and plastics \u2013 due to the different coefficients of thermal expansion of the materials \u2013 cracks or material peeling can occur.<br>An embrittlement of the material or a change in mechanical strength can also often be observed. For this reason, we recommend combining climatic storage with further checks of the product properties (hardness, strength, adhesive strength) before and after climatic storage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<div data-wp-context=\"{ &quot;autoclose&quot;: false, &quot;accordionItems&quot;: [] }\" data-wp-interactive=\"core\/accordion\" role=\"group\" class=\"wp-block-accordion is-layout-flow wp-block-accordion-is-layout-flow\">\n<div data-wp-class--is-open=\"state.isOpen\" data-wp-context=\"{ &quot;id&quot;: &quot;accordion-item-2&quot;, &quot;openByDefault&quot;: false }\" data-wp-init=\"callbacks.initAccordionItems\" data-wp-on-window--hashchange=\"callbacks.hashChange\" class=\"wp-block-accordion-item is-layout-flow wp-block-accordion-item-is-layout-flow\">\n<h3 class=\"wp-block-accordion-heading\"><button aria-expanded=\"false\" aria-controls=\"accordion-item-2-panel\" data-wp-bind--aria-expanded=\"state.isOpen\" data-wp-on--click=\"actions.toggle\" data-wp-on--keydown=\"actions.handleKeyDown\" id=\"accordion-item-2\" type=\"button\" class=\"wp-block-accordion-heading__toggle\"><span class=\"wp-block-accordion-heading__toggle-title\"><strong>What condition must samples be in for the climate change test?<\/strong><\/span><span class=\"wp-block-accordion-heading__toggle-icon\" aria-hidden=\"true\">+<\/span><\/button><\/h3>\n\n\n\n<div inert aria-labelledby=\"accordion-item-2\" data-wp-bind--inert=\"!state.isOpen\" id=\"accordion-item-2-panel\" role=\"region\" class=\"wp-block-accordion-panel is-layout-flow wp-block-accordion-panel-is-layout-flow\">\n<p>Original components or functional assemblies, ideally in the installed position.
