ISO 2781:2018 硫化橡胶或热塑性橡胶 密度的测定

标准编号：ISO 2781:2018

中文名称：硫化橡胶或热塑性橡胶 密度的测定

英文名称：Rubber, vulcanized or thermoplastic — Determination of density

发布日期：2018-06

标准范围

本文件规定了测定固体硫化橡胶和热塑性橡胶密度的两种试验方法。此类测定对于控制橡胶化合物的质量和计算生产给定体积材料所需的橡胶质量非常重要。本文件不包括橡胶相对密度的测定，即在给定温度下，给定体积橡胶的质量与等体积纯水的质量之比。

This document specifies two methods of test for the determination of the density of solid vulcanized and thermoplastic rubbers.Such determinations are of importance in the control of the quality of a rubber compound and in the calculation of the mass of rubber required to produce a given volume of material.This document does not cover the determination of the relative density of rubber, which is the ratio of the mass of a given volume of rubber to the mass of an equal volume of pure water at a given temperature.
