This site has been established for applicant and enrolled laboratories in the Carpet and Carpet Cushion (CCC) Laboratory Accreditation Program (LAP). On this site you will find important program information and links to documents required for successful participation in the program.
In 1981 NVLAP established the Carpet Testing Program for accrediting laboratories that test carpet and attached carpet cushion products. This program was developed in response to a request from the U.S. Department of Housing and Urban Development (HUD). Its purpose is to assist HUD in assessing the suitability of carpet and attached carpet cushion products for use in housing programs. HUD Use of Materials Bulletin No. 44 (UM 44), Building Products Standards and Certification Program for Carpet, includes the minimum requirements and standard test methods used for determining the acceptability of carpet and attached carpet cushion products for HUD housing.
In 1993 HUD issued Use of Materials Bulletin No. 72 (UM 72), Building Products Standards and Certification Program for Carpet Cushion, which includes minimum requirements and test methods for separate (not attached) carpet cushion products. In response to HUD's issuance of UM 72, the NVLAP Carpet Testing program was expanded to include requirements for testing separate carpet cushions. The expanded NVLAP program was renamed the Carpet and Carpet Cushion (CCC) Program in 1994.
For information on the requirements of accreditation see NIST Handbook 150 which contains the general requirements for accreditation of laboratories. In addition, NIST Handbook 150-6 contains specific requirements for carpet and carpet cushion laboratories.
Proficiency Testing Requirements
Periodically, NVLAP initiates interlaboratory proficiency testing for carpet and carpet cushions. The final report for Round 36 was released in August of 2012. Round 37 is underway. The approximate cost is $1,250 US and laboratories are notified and invoiced when each round begins.
