Commercial Products Testing

The NVLAP program for Commercial Products Testing (CPT) provides for laboratory accreditation to assure that standard test procedures for paints, paper, plastics, plumbing, roofing, and seals/sealants are performed properly. The CPT program uses standard test methods including those from ASTM International, American National Standards Institute (ANSI), ASME International, Technical Association of the Pulp and Paper Industry (TAPPI), and the General Services Administration (GSA).

The test methods for which a laboratory may seek accreditation are listed on the Commercial Products Testing program-specific application form found at NVLAP Application Forms
