ГОСТ 12020-72

Plastics. Testing methods of plastics resistance to chemical substances

Пластмассы. Методы определения стойкости к действию химических сред
The standard applies to plastics and establishes methods for determining the resistance to chemical environments. The essence of the methods consists in determining the change in mass, linear dimensions, the appearance of standard plastics samples in an unstressed state and cracking them in a stress-strain state after exposure for a certain period of time in reagents: liquid chemicals, solutions of solid chemicals and technical liquid media ( fuels, oils, etc.). The test results obtained according to this standard allow: to establish the relative resistance of various plastics in a given chemical environment; establish the relative resistance of the tested plastics in various chemical environments; to establish the effect of additives introduced into plastic on resistance in a given chemical environment or in several chemical environments. The method of determining the change in the mass of plastic samples after exposure to chemical reagents is also used to determine the amount of substances extracted from plastics when exposed to chemical reagents.

Стандарт распространяется на пластмассы и устанавливает методы определения стойкости к действию химических сред. Сущность методов заключается в определении изменения массы, линейных размеров, внешнего вида стандартных образцов пластмасс в ненапряженном состоянии и растрескивания их в напряженно-деформированном состоянии после выдержки в течение определенного периода времени в реагентах: жидких химических веществах, растворах твердых химических веществ и технических жидких средах (топлива, масла и т.п.). Результаты испытаний, полученные по настоящему стандарту, позволяют: установить сравнительную стойкость различных пластмасс в данной химической среде; установить сравнительную стойкость испытуемой пластмассы в различных химических средах; установить влияние введенных в пластмассу добавок на стойкость в данной химической среде или в нескольких химических средах. Метод определения изменения массы образцов пластмасс после выдержки в химических реагентах также применяют для определения количества экстрагируемых из пластмасс веществ при воздействии на них химических реагентов.
