Method 1 is to control the exposure period by checking the samples, and each sample should be equipped with a set of blue wool standards ;

Method 2 is to control the blue wool standard to control the exposure period, only one set of blue wool standard is needed for a batch of several multiple samples;mZgTextile Testing Instruments, Testing Equipment Manufacturer

Method 4 is used to check whether the sample is Compliant is to an agreed reference sample, the blue wool standard is not required but the exposure period is controlled by checking the reference sample;mZgTextile Testing Instruments, Testing Equipment Manufacturer

Method 5 checks whether the sample meets the agreed radiant energy, the test The sample can only exposed or fitted with a blue wool stand. The exposure time is determined according to the specified radiant energy. mZgTextile Testing Instruments, Testing Equipment Manufacturer

In the national standard system, IOS8429-1998 Textile color fastness test color fastness to weather: outdoor exposure and IOS8430-1998 Textile color fastness test color fastness to artificial weather: xenon there are badts 3 methods for the selection of exposure methods in Arc, of which method 1 and method 2 are the same as above, and method 3 is similar to method 5 above

Same. However, the exposure method in IOS843l-1998 Inspection and evaluation of textile color fastness test photochromism is specific, only the low grade blue wool standard 1 or L2 is required, which is determined based on the time it takes for the blue wool standard to change color The exposure time of the sample. There are also three exposure methods in IOSl6991—1997 Textile Color Fastness Tests: Color Fastness to Light at High Temperature: Xenon Arc. Method 1 and Method 3 are the same as above, and Method 2 is to control the exposure period by checking the specified minimum level standards. mZgTextile Testing Instruments, Testing Equipment Manufacturer
