Subp. 2.
General requirements.
A.
All regulated thermal insulation materials must be tested for compliance with the standards according to subpart 3, 4, 5, 6, 7, or 8. An insulation product that has been tested for compliance with another version of an ASTM standard for the product type and is composed of the identical material, for example the same chemical make-up, composition, or physical properties, but that has different dimensional characteristics, such as width, length, or thickness, does not need to undergo additional testing.
B.
When the ASTM amends, reorganizes, or modifies a standard test method and the manufacturer or testing laboratory desires to use the new version, the department may be petitioned to adopt the new test method version. Until the department adopts or decides not to adopt the new version, the petitioner may request a temporary variance, pursuant to Minnesota Statutes, sections 14.055 and 14.056, to use the new test method version.
C.
Manufacturers shall have a quality assurance program in place for all regulated thermal insulation products. A quality assurance program must be in place for installers of products whose manufacture is completed at the job site.
Manufacturers and other industry members must maintain an in-house quality assurance program in order for products to meet the required standards.
If a manufactured product fails to meet those required standards, the department shall notify the industry member to pursue corrective measures.
