本文件规定了使用热重分析仪（TGA）测定生胶、复合橡胶和硫化胶中灰分的两种方法。 这些方法适用于ISO 1629中所述M、O、R和U系列的生橡胶、复合橡胶或硫化橡胶: -方法A适用于测定生胶中的灰分。 -方法B适用于测定复合橡胶或硫化橡胶中的灰分。 本方法不适用于测定含有氯、溴或碘的生橡胶、复合橡胶或硫化橡胶中的灰分。 本文件不解释复合橡胶或硫化橡胶中无机化学成分产生的灰分。

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.
