The 6th SMIIC MC Training within the SMIIC MC Work Plan 2024 – 2026 V1 was the Calibration of gauge blocks according to ISO 3650:1999 «Geometrical Product Specifications (GPS) Length standards Gauge blocks» that took place on the 16 October 2024 virtually, technically hosted by SMIIC General Secretariat. 19 experts participated in the training.

The training was hosted by NMI: KAZMEST

General Description: The training covers information on the main standardized parameters and the calibration procedure for gauge blocks of grades K, 0, 1, 2 according to ISO 3650:1999 «Geometrical Product Specifications (GPS) – Length standards - Gauge blocks».

Objective, expected outcome: The purpose of this training course is to introduce ISO 3650 and review the basic standardized parameters and procedure of calibrating gauge blocks.

Who should attend: The training should be attended by the staff working in metrology laboratories at the level of national metrology institutes or laboratories who are involved or planned to be involved in calibration of gauge blocks.
