What is this standard about?
The accuracy of test sieving depends on the dimensional accuracy of test sieve openings. Therefore this standard is Part 2 in an international series which specifies technical requirements and testing of test sieves. This part looks at sieves made from perforated metal plates. The other parts are:
- Part 1 – Test sieves of metal wire cloth
- Part 3 – Test sieves of electroformed sheets
Who is this standard for?
- Test sieve manufacturers and users
Why should you use this standard?
It specifies technical requirements and corresponding test methods for test sieves of perforated metal plate and applies to test sieves having:
- Round holes with sizes from 125 mm down to 1 mm or
- Square holes, with sizes from 125 mm down to 4mm
in accordance with ISO 565.
Since accuracy is important, this part of ISO 3310 keeps hole tolerances as close as possible to what the manufacturing process allows.
Requirements other than hole tolerances, such as requirements for the pitch of holes, any corner radii, and plate thickness, have not been limited more closely than necessary, since the influence of these criteria on test sieving is of minor importance, and excessively strict requirements may make manufacture unnecessarily difficult.
What’s changed since the last update?
This international standard supersedes a British Standard: BS 410-2:2000. It’s also the fifth version of the international standard and constitutes a technical revision of the 1999 edition.
