标准摘要
[中文适用范围]： 本文件规定了使用极低橡胶硬度（VLRH）标度测定极软硫化或热塑性橡胶硬度的静载方法。 穿透深度与 VLRH 等级之间的关系是线性的。 [外文原描述]： This document specifies a dead-load method for the determination of the hardness of very soft vulcanized or thermoplastic rubbers using the very low rubber hardness (VLRH) scale. The relation between the depth of penetration and the VLRH scale is linear.
