BS 2782系列标准属于英国标准英标，是关于“塑料的试验方法”的标，在BS 2782关于老化测试部分主要是关于玻璃板下的日光暴晒照射、自然风化或实验室光源照射的颜色变化和性质改变的测定。

BS 2782英文简介

BS 2782-5-Method 552A1999 ISO 4582-1998

ISO 2782-1:2016 specifies three methods for the determination of the permeability to gases of vulcanized or thermoplastic rubber under a differential partial pressure.

The three methods specified are as follows:

- pressure sensor method (using vacuum): for determining the gas transmission rate, gas permeability coefficient, gas diffusion coefficient and gas solubility coefficient;

- simplified sensor method (using applied pressure): for determining the gas permeability coefficient only;

- gas-chromatographic method: for determining the gas transmi
