This proposed new standard is intended for fire-retardant treated structural glued laminated timber (glulam). There are existing ASTM standards for lumber, plywood, oriented strand boards, and laminated veneer lumber (LVL), but not glulam. FRT glulam products have been used in construction for a while without a consensus-based standard for qualification and characterization.
