The International Window Film Association published an explanation of ASTM F3561-22 on March 19, 2025, responding to questions about how the forced-entry test applied to window film. It emphasized that an individual film product should not be represented as a complete tested window or door system.

A June 23 update described a wider education campaign, including presentations to architects and the glass industry. The association also said members were working on a proposed standard for glazing retrofits. Participation in a working group was not evidence that a new retrofit standard had already been adopted.

There is an important chronology point for anyone using the older guidance now. ASTM’s current public page identifies F3561-25 as active, with a July 3, 2025 update date. The March explanation refers to an earlier edition; a new specification should identify the edition actually being required.

The current public scope says the method evaluates complete systems and that results apply to the configuration tested. It separately allows component testing under Appendix X1, producing a capability statement rather than a system rating. It also says the method is not a ballistic-resistance rating: test projectiles may penetrate the specimen.

For purchasers comparing safety-film proposals, the practical question is what was tested and how that configuration relates to the proposed installation. A standard number on a brochure is not enough to establish that relationship.

This article uses ASTM’s freely available scope and significance statements, not the full paid standard. It does not certify any product, approve a school-security design or establish the later status of the proposed retrofit standard.
