标准摘要
[中文适用范围]： 用于测定通过煮沸丙酮从细碎酚醛模塑材料样品中提取的物质量的重量分析法规范。 在受控条件下干燥提取物并通过称重确定残留物的质量。 丙酮可溶物的量（表观树脂含量）以原始测试部分的质量百分比表示。 [外文原描述]： Specification of a gravimetric method for the determination of the amount of matter that can be extracted by boiling acetone from a sample of finely divided phenolic moulding material. The extract is dried under controlled conditions and the mass of residue determined by weighing. The amount of acetone soluble matter (apparent resin content) is expressed as percentage by mass of the original test portion.
