scope:

This test standard describes minimum performance requirements for materials which are intended for use in cleanroom facilities. This standard evaluates the ability of the components to limit fire spread and smoke damage. All requirements in the standard must be met for materials to be acceptable in cleanrooms.

This standard is intended to verify that the product as described will meet minimum specific stated conditions of performance, safety, and quality, useful in determining the potential suitability for end-use conditions of these products.

Purpose

This test standard states FM Approvals test requirements and procedures for the evaluation of materials used in cleanroom occupancies mainly, but not restricted, for use in the semiconductor industry. The test evaluates the materials' fire propagation behavior and potential for smoke contamination using two indices: Fire Propagation Index (FPI) and Smoke Development Index (SDI).

This test standard does not qualify products for Approval based solely on these test results, as the end use of the product will determine the applicable Approval Standard requirements, if available, which will also have to be met to achieve Approval.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
