Description / Abstract:

This Standard specifies the method for determining the heat ageing properties of vulcanized rubber and thermoplastic rubber according to the accelerated ageing test and/or the heat resistance test. The test methods include the following Method A and Method B.

a) Method A, using the forced circulation type heat ageing test machine provided with an air blower

b) Method B, using the cell type heat ageing test machine or the natural ventilation type heat ageing test machine in which the air in test oven is ventilated slowly by convection

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 188: 2011 Rubber, vulcanized or thermoplastic-Accelerated ageing and heat resistance tests (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.

WARNING Persons using this Standard should be familiar with normal laboratory practice. This Standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices.
