The American Association for Laboratory Accreditation (A2LA) is a nonprofit, non-governmental, public service, membership society. The mission of A2LA is to provide comprehensive services in laboratory accreditation and laboratory-related training. Laboratories are accredited in the following fields: Acoustics & Vibration, Biological, Calibration, Chemical, Construction Materials, Electrical, Environmental, Geotechnical, Mechanical, Nondestructive, and Thermal. In addition to these broad fields, specifically-tailored programs are available for animal drugs, automotive electromagnetic compatibility (EMC), environmental lead (Pb), fertilizers, food testing, and putting green materials testing. Aldinger's scope identifies the specific testing or calibration capabilities for which we are accredited.
