📋 Scope / 适用范围 ai_extracted

This standard specifies the method for determining the permeability of dense shaped refractory products. For the determination of the permeability of shaped insulating refractory products, this standard may be referred to. The method specified in this standard takes into account the dynamic viscosity of gases. Therefore, the results obtained are not directly comparable with those obtained by earlier methods that did not consider viscosity. Air is generally used for the determination; other gases may be used when necessary, and the viscosities of air and nitrogen are provided.

本标准规定了测定致密定形耐火制品透气度的方法。对定形隔热耐火制品透气度的测定，可参照本标准。本标准所规定的方法考虑到气体的动力粘度。因此，所得的结果不可直接与早期没考虑粘度的方法所得的结果比较。测定时一般通空气，需要时可用其他气体，已给出空气和氮气的粘度。
