METHODS OF TEST FOR PAINTS AND VARNISHES: PART F16: EXPOSURE OF COATINGS TO ARTIFICIAL WEATHERING – EXPOSURE TO FLUORESCENT UV AND WATER (ISO 11507:1997, MOD)
This Malaysian Standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.
It specifies a test method for determining the resistance of paint coatings to artificial weathering in apparatus including fluorescent UV lamps and condensation or water spray.
NOTE. The ultraviolet light produced by the fluorescent tubes simulates only part of the UV region of the natural sunlight and consequently the test pieces are subjected to a small but destructive portion of the spectrum.
Due to the lack of energy of visible and infra-red radiation compared to sunlight the test piece is not heated above the temperature of the surrounding air which takes place in practical use.
