Standard Test Method for Determining Chemical Compatibility of Substances in Contact with Thermoplastic Pipe and Fittings Materials

Importancia y uso:

4.1 These procedures can be used to evaluate chemicals or materials expected to come in contact with plastic piping relative to causing environmental stress-cracking in thermoplastic materials. This testing results in determining time-to-failure versus engineering stress. This procedure can also be used in stress-rupture regression analysis, where a variety of stress levels are needed. The methodology can be readily adapted to conducting immersion tests in liquids or testing temperatures other than 73 °F (23 °C).
