1.1 This part of ISO 22088 provides information and general guidance relevant to the selection of the test
method to be used to determine environmental stress cracking (ESC).
1.2 Part 2 describes a method in which a test specimen is subjected to a constant tensile load, while
immersed in a stress cracking agent at a specified temperature. The time and/or stress at which the specimen
breaks is recorded.
1.3 Part 3 describes a method in which strips of plastic are subjected to a fixed flexural strain and exposed
to a stress cracking agent for a predetermined period.
1.4 Part 4 describes a method in which a hole of specified diameter is drilled in a specimen and an
oversized steel ball or pin is inserted into the hole while the test specimen is brought into contact with a stress
cracking agent.
1.5 Part 5 describes a method in which a constant tensile deformation is applied to a specimen which is
immersed in a stress cracking agent at a temperature selected for testing.
1.6 Part 6 describes a method in which a slowly increasing strain is applied to a specimen immersed in a
stress cracking agent.
1.7 These methods are applicable to thermoplastic materials only.
1.8 These are essentially ranking tests and are not intended to provide data to be used for design or
performance prediction.
Dieser Teil von ISO 22088 liefert die für die Auswahl des Verfahrens zum Prüfen auf ESC relevanten Informationen und allgemeinen Anleitungen.
