Annotation of standard text ASTM C1289-25 :

This specification covers the general requirements for faced thermal insulation boards composed of rigid cellular polyisocyanurate surfaced with other materials. This standard is intended to apply to rigid cellular polyurethane-modified polyisocyanurate thermal insulation board products that are commercially acceptable as nonstructural panels useful in building construction. The materials are classified as follows: Types I, II, III, IV, and V. Under Type I are Classes 1 and 2. Under Type II are Classes 1, 2, and 3. Under Type II Class 1 are Grades 1, 2, and 3. Rigid polyisocyanurate thermal insulation boards shall be based upon the reaction of an isocyanate with a polyol, or the reaction of an isocyanate with itself, or both, using a catalyst and blowing agents to form a rigid closed-cell-structured polyisocyanurate foam. The insulation foam core shall be homogeneous and of uniform density. The following test methods shall be performed to conform to the specified requirements: conditioning; thermal resistance; compressive strength; dimensional stability; flexural strength; tensile strength perpendicular to board surface; water absorption; and water vapor transmission.
