Building products that are used outdoors are subjected to varying weather conditions. For building products manufacturers, two important standards that outline requirements for products subjected to outdoor environments include:. In order to conduct testing per the requirements in standards ASTM G and ASTM D, testing labs use specialized equipment to simulate solar radiation using xenon lamps and advanced filter systems.
Depending on the type of product being tested and its performance requirements, test specimens are exposed to weathering conditions for varying duration times. Samples are then compared to unexposed control samples to measure color changes, change in physical properties, haze, chalkiness, durability, cracking, corrosion, strength, stiffness, and other properties.
Controlled laboratory tests for accelerated weathering can offer crucial and meaningful data for building product manufacturers when making decisions about production of materials. The data collected from these tests can assist in improving product durability, increasing product quality, or simply assuring that current manufacturing processes are competitive.
