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.
Timothy Rasinski, Program Manager
The NVLAP Thermal Insulation Materials (TIM) LAP is in need of an assessor. This is a contracted position. Candidates should have at least five years experience with a wide range of testing of thermal insulation materials, particularly ASTM C177 and C518. Experience with ISO/IEC 17025:2005 is a plus. Candidates must be fluent in English, have excellent communications skills, and be willing to travel approximately four weeks out of the year. If interested, please contact the NVLAP TIM program manager.
The NVLAP Thermal Insulation Materials (TIM) LAP is in need of a proficiency testing administrator. Candidates should have experience with common thermal insulation material test methods, especially ASTM C177. Proficiency testing must be in compliance with the requirements of ISO/IEC 17043. The administrator is contracted by NVLAP to select testing materials, distribute the materials and testing protocols to participant labs, analyze results, and submit a draft report to NVLAP for final review before distribution. If successful, the contract will be renewed more or less annually for future rounds. If interested, please contact the TIM program manager.
