Anotácia

This specification covers the classification, materials of construction, workmanship, physical requirements, and methods of testing glass-fiber-reinforced polyester composite wall and ceiling panels intended for use in light construction and semi-structural applications. The panels shall be divided into four classifications based on relative response to the laboratory flammability: Class A; Class B; Class C; and Class D. These classifications may be further subdivided into grades based on nominal thickness when tested: Grade 1; Grade 2; Grade 3; Grade 4; Grade 5; Grade 6; and Grade 7. The polyester resin used in the composite shall be a thermosetting polyester resin with cross-linking monomers composed of polymeric esters in which the recurring ester groups are an integral part of the main polymer chain. The resin shall be reinforced with glass fibers. Conditioning; length and width; squareness; thickness; camber; color; impact resistance; and burning characteristics tests shall be performed to conform to the requirements specified.
