Objective

Objectives of the mass laboratory is to maintain & disseminate the national standards of mass. Mass laboratory provides calibration services to facilitate Trade, Industry, health and environmental protection. The Quality of calibration result are assured by participation of Inter - laboratory comparisons.

Standards

• National prototype of kilogram.
• NO.s Reference weight of kilogram
  • OIML class E1 weight sets
  • OIML class E2 weight sets
  • OIML class F1 weight sets
  • OIML class F2 weight sets
  • OIML class M weight sets
