ASTM C726-12

This specification covers the composition and physical properties of mineral wool insulation board used above structural roof decks as a base for built-up roofing and single ply membrane systems in building construction. The use of thermal insulation materials covered by this specification may be regulated by building codes or other agencies that address fire performance, or both. Specimens shall be sampled, prepared, tested, and conform accordingly to the following physical properties: compressive resistance, tensile strength, breaking load strength, water absorption, response to thermal and humid aging, linear dimensional change, thermal resistance, surface burning characteristics, and dimensions.
