本文件规定了一种在标准条件下进行的方法，用于制备和储存多组分涂层系统的样品，并随后通过测量特定性能评估其适用期。 在短时间内（例如3小时）固化的反应性系统的适用期将接近凝胶点，因此需要根据ISO 2535测试其特定性能。 该方法既可以通过在指定时间段后确定特定特性来进行通过/失败试验，也可以通过在方便的时间间隔内重复测定来确定适用期。 本文件不适用于产品使用过程中的现场控制。其目的是在实验室中确定“适用期”。 供应商在向用户提供建议时，可出于实际原因（如启动温度）修改从本试验方法中获得的值，然后应将其称为“实际适用期”。

This document specifies a method, carried out under standard conditions, for preparing and storing a sample of a multicomponent coating system and subsequently assessing its pot-life by measuring a particular property/ies. Reactive systems curing within a short period of time, e.g. 3 h, will have the end of their pot life so near to the gel point that they will need to be tested for that particular property in accordance with ISO 2535. The method can be carried out either as a pass/fail test by determining the particular property/ies after a specified period of time, or as determination of the pot life by repeating determinations at convenient intervals of time. This document is not intended for in situ control of products during their application. It is intended to determine "pot life" in the laboratory. The value obtained from this test method can be subject to modification by suppliers for practical reasons (e.g. starting temperature) when giving advice to users and should then be called the "practical pot life".
