橡胶.灰分的测定.第2部分:热重量分析(TGA)

[中文适用范围]： 本文件规定了使用热重分析仪（TGA）测定生胶、混炼胶和硫化胶中灰分的两种方法。 这些方法适用于 ISO 1629 中描述的 M、O、R 和 U 系列生橡胶、复合橡胶或硫化橡胶： ——方法 A 适用于测定生橡胶中的灰分。 ——方法B适用于混炼橡胶或硫化橡胶中灰分的测定。 本方法不适用于含氯、溴、碘的生胶、混炼胶或硫化胶中灰分的测定。 本文件不包括对复合橡胶或硫化橡胶中无机化学成分的灰分结果的解释。 [外文原描述]： This document specifies two methods for the determination of ash from raw rubbers, compounded rubbers and vulcanizates using a thermogravimetric analyser (TGA). The methods are applicable to raw, compounded or vulcanized rubbers of the M, O, R and U families described in ISO 1629: — Method A is applicable for the determination of the ash from raw rubbers. — Method B is applicable for the determination of the ash from compounded or vulcanized rubbers. The methods are not applicable for the determination of the ash from raw rubbers, compounded or vulcanized rubbers containing chlorine, bromine or iodine. This document does not cover the interpretation of the ash results from the inorganic chemical contents of compounded or vulcanized rubbers.
