What is BS 1752- Laboratory sintered (fritted) filters about?
BS 1752 specifies a system of porosity grading, classifying and designating laboratory sintered (fritted) filters by the determination of pore size index.
BS 1752 is applicable to laboratory filters made of glass, vitreous silica, ceramics, metals, and plastic materials.
Who is BS 1752 - Laboratory sintered (fritted) filters for?
BS 1752 on the specification for laboratory sintered (fritted) filters is useful for:
- Laboratory equipment manufactures
- Quality control personnel
Why should you use BS 1752- Laboratory sintered (fritted) filters?
Laboratory sintered (fritted) filters are used for the filtration of liquids and gasses in the laboratory. It incorporates a porous glass disc as a filter media, which is non-corrosive and reusable. It is also used for gas washing, dispersion, and absorption. And the pore size relates to the filter's ability to filter out particles of a certain size.
BS 1752 provides you with the requirements of laboratory sintered (fritted) filters by providing a test method of determining the pore size index. BS 1752 provides you with requirements of quality, and grading of filters and provides limits for pore size index.
BS 1752 provides you with the tests to assess the uniformity of filters and determine the air permeability of the filters. BS 1752 helps you manufacture high-quality laboratory sintered (fritted) filters.
What’s changed since the last update?
BS 1752:1983 supersedes BS 1752:1963 which is withdrawn. BS 1752:1983 includes some technical changes with respect to BS 1752:1983. These include:
- The porosity grading and designation have been changed
- Whilst all the designations have changed, only some of the limits of pore size have changed
- To assist purchasers of laboratory sintered filters, the changes are shown graphically in a National appendix.
