What’s the Difference between a Traceable Certificate and a NVLAP+ Accredited Certificate?
Calibration weights are high quality stainless steel calibration weights for scale and balance calibration. We are proud to offer the finest quality calibration weights – precision weights, test weights and certified weights from Troemner – the world’s leading manufacturer.
Calibration weights can come with two different types of certificates – a Traceable Certificate, or an NVLAP+ Accredited Certificate. What’s the difference?
Traceable Certificate - Weights
The Traceable Certificate is designed for laboratories and companies that require traceability, but do not need to meet any stringent regulatory requirements. The Traceable Certificate measurement process is based on a single standard and utilizes one series of comparisons.
NVLAP+ Accredited Certificate - Weights
The NVLAP+ Accredited Certificate provides compliance in both measurement process and data reported to the customer to meet a variety of standards including NVLAP Handbook 150-2, ISO/IEC 9000, ISO/IEC 17025, FDA, GMP, GLP, DOD, ANSI/NCSL Z540-1, and nuclear requirements.
Troemner's NVLAP Laboratory Code is 105013-0. This NIST administered National Voluntary Laboratory Accreditation Program (NVLAP+) approves, through periodic audits, all processing and weighing procedures, as well as certificate format and content. Calibration procedures vary by tolerance class requested. For example, for higher accuracy classes such as Troemner UltraClass Series, ANSI/ASTM Class 000, 00, 0 and 1, Class E0*, OIML R 111 Class E1, and E2, Troemner performs a multiple weighing procedure utilizing our secondary working standards to determine the mass of a customer's weight.
The NVLAP+ Accredited Certificate includes:
