标准范围

重量分析法规范，用于测定可通过煮沸丙酮从细碎酚醛模塑材料样品中提取的物质量。在受控条件下干燥提取物，并通过称重确定残留物质量。丙酮可溶物（表观树脂含量）的量表示为原始试验部分的质量百分比。

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.
