PACKAGING TEST METHOD TM No: QMKA-PE-056TITLE: Light Fastness Test For Ink Printed MaterialsReleased Date: Rev. No:Originating Department: Originating Author: 1. PURPOSE AND SCOPE1.1 Purpose: The method is to provide instructions to assess the light fastness of ink printed materials.1.2 Scope: The method is applicable for all print substrates such as paper, board，plastic films , thin metal plate ( i.e tins) and to all printing processes.2. EQUIPMENT AND MATERIALS USED IN TEST2.1 A xenon arc lamp apparatus with either air cooled or water cooled device;2.2 Blue wool references, in accordance with ISO 12040-1997;2.3 A grey scale is used for the determination of colour change in accordance with ISO 105-A02;2.4 Black-Panel-Thermometer, in accordance with ISO 12040-1997;2.5 Light source, is a xenon arc lamp with a colour temperature of 5500 K to 6500 K;2.6 The filter should completely absorb radiation at wavelengths below 310 nm. The transparency of the glass filters shall be at least 90 % in the range of wavelengths from 380 nm to 700 nm (simulating sunlight behind window glass).3. SAFETY AND HANDLING3.1 Test personnel must have the basic knowledge and been trained on the materials and equipment used in this test method. 3.2 Appropriate personal protective equipment (PPE) should be worn if necessary.4. SAMPLES TO BE TESTED 4.1 Test samples should be produced at least 24 hour prior to test. Preconditions test samples for at least 2 hours at room temperature prior to test. 5. PROCEDURE5.1 The test pieces and the blue wool references are mounted together as closely as possible in a well-ventilated test chamber;5.2 Use an opaque board with the thickness of 0.5 mm at least to partly cover the test pieces and the blue wool references;5.3 The temperature of the test pieces shall not exceed 45 as measured by the Black-Panel-Thermometer. Expose the samples to the light in a prescribed manner for a time sufficient to cause a distinct change, which is defined as equal to or less than grade 3 of the grey scale. Take out the test pieces and blue wool reference from the chamber. 6. INTERPRETATION OF RESULTS6.1 Compare the color change between the test pieces and blue wool reference, give the test piece a light-fastness rating that corresponds to the number of the blue wool reference that has the same level of color change.If the change of the test piece falls between the two successive numbers of blue wool references, the light fastness rate should be given the two corresponding numbers (e.g. 6-7). This rating method is not applicable to light fastness rating below 5. If the test pieces color darkens, this test method is not applicable.6.2 The light-fastness rating should be 6 or above.7.
