BS 1752:1983

This standard BS 1752:1983 Specification for laboratory sintered or fritted filters including porosity grading is classified in these ICS categories:

• 71.040.20 Laboratory ware and related apparatus

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.

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.
