The two OSFM listings have different scopes. Listing 8110-2042:0503 covers a deck-surface assembly, while 8170-2042:0504 is a material classification under extended ASTM E84 testing; do not substitute one test path for the other. Match the board profile, fastener system, spacing, joists, and installation details to OSFM listing 8110-2042:0503 and the manufacturer instructions. OSFM listing is not a permit.
