ISO 4892-3 Testing Instruments
Standard prescribed for testing the effect of laboratory lighting on the properties of the plastic material. Part 3: Fluorescent Ultra Violet lamps
This part of the standard gives the methods that must be used for exposure of the test specimen to fluorescent ultraviolet radiations, moisture, high temperature, etc. This standard is used to simulate the actual weathering effects that occur on the material when they are exposed actually in the environments with solar radiations or excessive moisture.
