At Absolute, we have what your laboratory needs to stay calibrated, controlled & accredited. In 1999 we were part of the first class of Providers of Proficiency Testing to obtain NVLAP Accreditation for satisfactory compliance with criteria established in Title 15, Part 285 Code of Federal Regulations. Since then, we have maintained our accreditation through both On-Site and Off-Site audits. These criteria encompass the requirements of ISO/IEC Guide 17025:2005 and the relevant requirements of ISO 9001:2000 for a supplier of calibration or test results. As accreditations and needs have changed, Absolute has led the way. Absolute Standards Inc. has also been accredited by A2LA as a Proficiency Testing Provider, Certificate #, 2429.01
