The Thermal Insulation Materials (TIM) Program was established in 1979 at the request of three private sector thermal insulation trade associations. The purpose of the program is to accredit laboratories that produce reliable thermal insulation test data. The TIM program was the first of the NVLAP laboratory accreditation programs. For information on the requirements of accreditation, see NIST Handbook 150, which contains the general requirements for accreditation of laboratories. In addition, NIST Handbook 150-15 contains specific requirements for thermal insulation materials laboratories.
Proficiency Testing Requirements
After a long hiatus, the thermal insulation program ran a successful PT. The PT covered several test methods within the thermal insulation material testing laboratories program. The test demonstrated close agreement amongst the laboratories within acceptable limits. It has yet to be decided how often the proficiency test will be performed. Laboratories will be notified at a later date of the next scheduled PT. NVLAP would like to extend appreciation to NVLAP assessor, Dan Flynn, who coordinated the test, analyzed the results and provided the report.
