JSA JIS K 6251

Abstract

This Standard specifies the determination method for the tensile stress-strain properties of vulcanized rubbers and thermoplastic rubbers. The properties to be determined shall be the tensile strength, elongation at break, stress at a given elongation, elongation at a given stress, tensile stress at yield and elongation at yield. The measurement of the tensile stress at yield and the elongation at yield applies only to vulcanized rubbers and thermoplastic rubbers having a yield point. NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. ISO 37: 2011 Rubber, vulcanized or thermoplastic-Determination of tensile stress-strain properties (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/ lEe Guide 21-1. WARNING 1 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 of this Standard to establish appropriate safety and health practices. WARNING 2 Certain procedures specified in this Standard might involve the use or generation of substances, or the generation of waste, that could constitute a local environmental hazard.
