This site has been established for applicant and enrolled laboratories in the Thermal Insulation Materials (TIM) Laboratory Accreditation Program (LAP). On this site you will find important program information and links to documents required for successful participation in the program.
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
Periodically, NVLAP initiates interlaboratory proficiency testing for thermal insulation materials. The final report for Round 31 was released in February 2010. Proficiency testing is on hold pending acquisition of a new proficiency testing administrator. The approximate cost is $1,000 US, and laboratories will be notified and invoiced when proficiency testing resumes.
Frequently Asked Questions (FAQs)
Q: How much does accreditation cost?
A: Thermal insulation testing laboratories in the United States that are scheduled for an on-site assessment pay a fixed on-site assessment fee that is in addition to the administrative/technical support fee and any proficiency testing fees. Additional information about fees for accreditation is published on the NVLAP Fee Structure page of the NVLAP website.
Laboratories located outside of the United States: Non-U.S. laboratories pay actual expenses for assessments and will be invoiced the full cost of the assessment shortly after submitting the application.
