When exploring accreditation boards for calibration laboratories, people often come across these two organizations: ACLASS and A2LA. Although ACLASS and A2LA may have subtle differences between them, they are really more similar than some might think, especially in regards to their accreditation of calibration laboratories.
ACLASS and A2LA are both nonprofit, non-governmental bodies that provide accreditation services to public and private sector organizations. They are both signatories to the International Laboratory Accreditation Cooperation (ILAC) MRA, and are recognized by ILAC, APLAC, and IAAC as signatories of multilateral recognition arrangements. Also, they both provide ISO/IEC 17025 accreditation for calibration labs. The ISO/IEC 17025 accreditation holds calibration labs to a standard of consistent competency in their services, and certifies that the accredited organization is one that can be relied on.
ACLASS is a brand of the ANSI-ASQ National Accreditation Board, which is jointly owned by the American National Standards Institute and the American Society for Quality. Although the ANSI-ASQ officially began giving accreditation in the early 1990s, they trace their roots back to 1957 when the European Economic Community was first formed. A2LA was established in 1978.
e2b calibration is ISO/IEC 17025 accredited through ACLASS. Other companies accredited by ACLASS include Caterpillar, General Electric, NASA Johnson Space Center, the U.S. Army, and the USDA.
