Rubber, vulcanized or thermoplastic-Determination of flex cracking and crack growth (De Mattia type)
 N JIS K 6260

Annotation

This Standard specifies a method of determination of the resistance of vulcanized or thermoplastic rubbers to the formation and growth of cracks, when subjected to repeated flexing on the De Mattia type machine.

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

ISO 132: 2005 Rubber, vulcanized or thermoplastic—Determination of flex cracking and crack growth (De Mattia) (MOD)

The 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/ lEC 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.
