Function, rubber sheet according to a use

Conforming Sheet of Expressway Standard

【 Features 】

•Complies with each standard

*Hardness measurement is revised to “After 3 seconds” according to JIS K 6253 (2006). However, generally, the conventional "measurement within 1 second" is to be the mainstream for nominal hardness, so this result is measured value and the measurement result after 3 seconds is shown in ().
