ActivePaper and board - Determination of air permeance(medium range) - General method
纸和纸板 透气度的测定（中等范围） 通用方法
Application Summary AI generated
This standard specifies a general method for measuring the air permeance of paper and board within a medium range (typically 1×10⁻² to 1×10² µm/(Pa·s)). It is applied in the paper industry for quality control and product specification, particularly for materials like filter papers, cigarette papers, and packaging boards where controlled air flow is critical. The method is used in manufacturing and testing laboratories to ensure consistent porosity and performance characteristics.
