- Scope
- This standard specifies the method for determining the air permeability of dense shaped refractory products. For the determination of air permeability of shaped heat insulation refractory products, you can refer to this standard. The method specified in this standard takes into account the kinetic viscosity of the gas. Therefore, the results obtained are not directly comparable to those obtained by earlier methods that did not take viscosity into account. Air is generally used for measurement, and other gases can be used if necessary. The viscosities of air and nitrogen have been given.
