ACCELERATED WEATHERING TEST METHOD OF THERMOPLASTIC RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To provide an accelerated weathering test method of a thermoplastic resin molding capable of acquiring in a very short time, a test result having excellent correlation with deterioration in a natural environment of the thermoplastic resin molding.;SOLUTION: In this accelerated weathering test method, the thermoplastic resin molding is irradiated with an ultraviolet ray emitted from a mercury lamp at a normal temperature under a normal pressure. In the accelerated weathering test method, a paint film surface is irradiated with the ultraviolet ray emitted from the mercury lamp at a normal temperature under a normal pressure, concerning the thermoplastic resin molding having the paint film surface to which painting is applied. In the accelerated weathering test method, the wavelength of the ultraviolet ray emitted from the mercury lamp is 150-300 nm, and the intensity of the ultraviolet ray is 15-49 mW/cm².;COPYRIGHT: (C)2008,JPO&INPIT
