ASTM D4587

Manufacturer of GRP/FRP of Enclosures and Kiosks in UAE

What is the test?

ASTM D4587 classification defines the standard practice for fluorescent UV and condensation exposures of paint and related coatings. Our glass reinforced polyester laminate, which is the primary material across our product range is constructed with a protective layer of gelcoat having a high thickness of 300 - 450 microns. The protective gelcoat serves as the first line of defense outdoors against weathering and UV exposures in extreme hot and cold climates. The standard is primarily based on the external integrity and appearance of our GRP enclosures when exposed to outdoor conditions over an extended period.

How is it tested?

Our glass reinforced polyester laminate is tested in a controlled laboratory with a simulation of accelerated weather with an exposure cycle of 8 hours UV followed by 4 hours condensation continuously. The ultraviolet is generated from a UVA 340 lamp under the guidelines of the ASTM G154 standard. Thereafter the simulation, the GRP laminate is physically inspected and compared to a control specimen. The GRP laminate should not display any deterioration like chalking, flaking, wrinkling, blistering or cracking. The ASTM D4587 test methodology and classification is equivalent to ISO 11507:1997.

Where is it tested?

Our laminate is type tested at the renowned international testing laboratory Exova to certify our products to be weather resistant. ASTM International is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. ASTM, founded in 1898 as the American Section of the International Association for Testing Materials, predates other standards organizations such as the BSI (1901), IEC (1906), DIN (1917), ANSI (1918), AFNOR (1926), and ISO (1947). Adherence to the standard is mandatory across the GCC region and globally.
