Standard Method of Test for Analysis of Structural Steel Coatings for Hindered Amine Light Stabilizer (HALS)
受阻胺光稳定剂(HALS)用结构钢涂层分析的标准试验方法
AASHTO T 338-09(2019)旨在确定双组分丙烯酸氨基甲酸乙酯涂层多元醇部分中是否存在受阻胺光稳定剂(HALS)。
This method is designed to determine the presence of hindered amine light stabilizer (HALS) in the polyol portion of a two-component acrylic urethane coating.This standard was formerly designated as provisional standard TP 66.
