    Abstract - (Show below) - (Hide below)

    Covers glass, silica, ceramics, metal or plastics filters. Specifies integrity, resistance to pressure, grading according to pore size and designation. Appendices give test methods for pore size index, uniformity and air permeability.

    Scope - (Show below) - (Hide below)

    This International Standard specifies a system of porosity grading, classifying and designating laboratory sintered (fritted) filters by the determination of pore size index.

    It is applicable to laboratory filters made of glass, vitreous silica, ceramics, metals and plastic materials.

    Test methods are included in Annex B and Annex C for the determination of air permeability and uniformity of pore size, but these characteristics do not form part of the requirements of this International Standard.
