NATIONAL STANDARDS TESTING LABORATORY
Precision Force Calibration
Accredited Force Calibration to ASTM E 74 and E 4
Certificate # L2271 Calibration
Traceability and Compliance
The force standards employed by National Standards Testing Laboratory are standardized or calibrated directly by the National Institute of Standards and Technology (formerly NBS). All calibration certificates and reports of calibration reference the NIST Lab Numbers applicable to the NSTL Standards used in the calibrations. NSTL operates in compliance with the requirements of MIL-STD-45662A, ISO 10012-1, and 10CFR Part 21. NSTL is continuously audited for such compliance by subscribers to its calibration services. Calibrations are performed in accordance with the current version of ASTM Specification E 74; "Standard Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines". NSTL will also perform calibrations in accordance with other recognized consensus specifications, or design and execute special tests of force measuring instruments as requested by the submitter.
National Standards Testing Laboratory has completed the accreditation process with the ANSI-ASQ National Accreditation Board (ANAB). ANAB Accredited Certificate Number L2271. National Standards Testing Laboratory is accredited to ISO/IEC 17025:2005 for force calibration in accordance with the ASTM E74 Specification in Compression and Tension over the ranges from 10 lbf to 1,000,000 lbf and machine calibration in accordance with the ASTM E 4 Specification up to 6,000,000 lbf. Please see the accreditation page for copies of the certificates issued by ANAB pertaining to the accreditation of National Standards Testing Laboratory.
