Scope: What is ISO 29664 - testing plastics using artificial weathering about? When plastics come in contact with chemicals in the environment such as motor fuels, lubricants, etc., they may experience weathering. ISO 29664 provides you with guidelines for artificial weathering tests intended to evaluate plastics for use in heavily polluted outdoor environments. Acidic precipitation can have a significant effect on the photochemical ageing of many polymers. In some cases, this is due to an attack on the stabilizers or fillers like CaCO3 applied in technical polymers. The mechanisms differ from those of harmful gases, which essentially constitute the initial products of acidic precipitation. ISO 29664
