The National Institute of Standards and Technology?issued mass and volume standards to all states. This is to provide uniformity throughout the country. The State Metrology Laboratory located in Las Cruces maintains the Official State Standards (OSS) for New Mexico. The use of these standards ensures a fair and equitable marketplace for producers, sellers, and consumers.
All mass and volume test standards used by producers, weights and measures repair agencies, and state inspectors are certified. This is done annually in the laboratory with all laboratory measurements being conducted under conditions and techniques. These conditions and techniques are recognized as recommended laboratory practices by NIST.
Laboratory Capabilities – The laboratory can provide mass calibrations from 1 mg (0.000002 lbs) to 2268 kg (5000 lbs). This is done with comparison to the Official State Standards. Small volume calibrations below 5 gallons are determined gravimetrically. Large volume transfers are performed on general purpose artifacts from 5 to 1500 gallons. That is, emptying a standard into a test device.
The Metrology Program is responsible for:
- Certification of state weights and measures standards.
- Maintenance of recognized certification standards.
- Providing scheduling and pricing information.
- Certification of weights and measures standards, for a fee, among register service agencies, local agencies, industry, and the general public.
