标准简介：This part of ISO 5636 specifies a method of determining the air flow rate through unit area of a sheet of paper or board, under unit pressure difference using apparatus called the Sheffield instrument.
The method is applicable to papers and boards having air permeances between 0,02 μm/(Pa·s) and 25 μm/(Pa·s). The method is not suitable for papers and boards with a rough surface, such as crepe paper and corrugated papers, which cannot be securely clamped to avoid surface leakage.
