No. NPL no longer offers a service for the calibration of Test Sieves.

Two laboratories in the UK that still offer a calibration service for test sieves are:

• Endecotts Limited
• Impact Test Equipment Limited

Details of both can be found on the UKAS website. There is a British Standard for the specification of Test Sieves - BS 410:1986. Calibration tests are defined in Appendix F of this standard.

BS 410:1986 has now been withdrawn and replaced by BS 410-1:2000 and BS 410-2:2000, which reproduce verbatim ISO 3310.
