3M Scotchcal Floor Overlaminates 3645 and 3647: fire rating
Every fire result 3M publishes for this film, the substrate the specimen was mounted on, and whether each rating is a test of this product. Best evidence basis across its rows: Tested — the basis is per row, so read the standard beside it.
These are 3M's published results, not our testing. For a permit or a fire marshal, request the current certificate for your product and lot. Nothing here replaces the authority having jurisdiction's approval. We install film; we do not certify it.
Every rating on file
| Standard | Result | Specimen mounted on | Evidence basis | Source |
|---|---|---|---|---|
| UL 410 (slip resistance) | UL Classified for slip resistance, file SA11595 ✓ Re-checked 2026-09-23 against the current document. | Walkway surface test, not a flame test | Tested | 3M Product Bulletin — Scotchcal Luster Overlaminate 3645 and Matte Overlaminate 3647 |
| ASTM E84 | The bulletin prints no flame-spread result and refers to the online catalog or a phone call ✓ Re-checked 2026-09-23 against the current document. | — | Not published | 3M Product Bulletin — Scotchcal Luster Overlaminate 3645 and Matte Overlaminate 3647 |
The floor-graphic trap: these carry a slip certification, not a flame one. A film 'UL classified' for floors says nothing about flame spread.
What to hand a fire marshal
- UL 410 (slip resistance) (Tested): the report cited in that row tests this product to that standard — hand it over when that standard is the one the fire marshal asked for (a slip or EU test does not answer an ASTM E84 request). A named third-party report tests this exact product.
- ASTM E84 (Not published): there is no published result to hand over — request the current certificate for your product and lot from 3M before the install date. The current bulletin states no fire result and refers the question to 3M or the online catalog. Absence of a number in the document is not a failing grade — it means you must request the certificate for your lot.
