Plastics. Methods of exposure to determine the wavelength dependent degradation using spectrally dispersed radiation subscription-only and the most commonly usedWhat is ISO 21475 Determine the wavelength dependent degradation of plastics about? ISO 21475 determine the wavelength dependent degradation of plastics. This international standard helps its users to produce products that are more durable to ultraviolet radiation. ISO 21475 specifies methods of determining the spectral response of all kinds of plastic materials to ultraviolet and visible radiation by an irradiation test with spectrally dispersed
