scope:

This specification covers the classification, material of construction, workmanship, physical properties, and methods of testing glass-fiber reinforced plastic panels in various profiles intended for use as casing, louvers, and similar applications on cooling towers. FRP panels as covered by this specification may also be suitable for other uses in cooling towers. Consult manufacturers, regarding the suitability of FRP for other applications.

Supplementary information on glass-fiber reinforced plastic (FRP) panels may be obtained from ASTM D-3841 Standard Specification for Glass Fiber-Reinforced Polyester Plastic Panels or directly from the manufacturers.

Laboratory flammability tests (E84/UL-723) applicable to this standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire risk of materials, products, or assemblies under actual fire conditions.
