CRRC accredited laboratories have undergone specific training to perform approved test methods in the CRRC Product Rating Programs for roof and wall products. Licensees are responsible for choosing a CRRC-approved test lab and test farm to begin product testing and weathering for the relevant CRRC Product Rating Program (roof or wall).
An Accredited Independent Testing Laboratory (AITL) is approved to submit test results to the CRRC for roof and/or wall products seeking a CRRC product rating. An AITL is completely independent from any roofing or wall manufacturing company, seller, or distributor. For information about becoming an AITL, visit Become an Accredited Testing Laboratory.
An Accredited Manufacturer Testing Laboratory in the Roof Product Rating Program (Roof AMTL) is a manufacturer laboratory that participates in the CRRC’s biannual Interlaboratory Comparison Study. For information about becoming a Roof AMTL, visit Become an Accredited Testing Lab.
An Accredited Manufacturer Testing Laboratory in the Wall Product Rating Program (Wall AMTL) is a manufacturer laboratory that is able to submit certain radiative property and color measurements for the Wall Color Family Program. Wall AMTLs also participate in the CRRC’s biannual Interlaboratory Comparison Study. For information about becoming a Wall AMTL, visit Become a Licensee: Wall Program.
