BS ISO 11236:2017适用于各种用于化学反应的取代对苯二胺抗降解剂（PPD） 橡胶工业。PPD的三个一般类别是二烷基、烷基芳基和二芳基，它们被使用 赋予橡胶耐臭氧性。以下试验方法对评估生产PPD的纯度具有重要意义，以及 因此，它们适用于橡胶。本文件规定如下:用气相色谱法（GC）测定纯度；用高效液相色谱法测定纯度- 高效液相色谱法；灰分的测定；挥发性物质的测定。交叉引用:ISO 1772ISO 15528:2013 ED2ISO 1042:1998ISO 6472:2017ISO/TR 9272购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 11236:2017 applies to a variety of substituted p-phenylenediamine antidegradants (PPDs) used in the rubber industry. The three general classes of PPDs are dialkyl, alkyl-aryl and diaryl, which are used to impart ozone resistance to rubber.The following test methods are of greatest significance in assessing the purity of production PPDs, and hence their suitability for use in rubber. They are specified in this document as follows:determination of purity by gas chromatography (GC);determination of purity by high-performance liquid chromatography (HPLC);determination of ash;determination of volatile matter.Cross References:ISO 1772ISO 15528:2013 ED2ISO 1042:1998ISO 6472:2017ISO/TR 9272All current amendments available at time of purchase are included with the purchase of this document.
