ISO 12460-5人造板.甲醛释放量的测定 第5部分—标准简介

This part of ISO 12460 specifies an extraction method known as the "perforator method". It is used forthe determination of the formaldehyde content of unlaminated and uncoated wood-based panels.

ISO 12460的这一部分规定了一种称为“射孔器法”的提取方法。它用于测定未层压和未层压人造板的甲醛含量。

ISO 12460-5人造板.甲醛释放量的测定 第5部分—检测原理

The formaldehyde is extracted from test pieces by means of boiling toluene and then transferred intodistilled or demineralized water.The formaldehyde content of this aqueous solution is determinedphotometrically by the acetylacetone method

通过煮沸甲苯从试样中提取甲醛，然后将其转移到蒸馏水或软化水中。通过乙酰丙酮法测定该水溶液中的甲醛含量。
