Compliant Standards:
ASTM F1319. AATCC 8/165. BS 1006 D02. GB/T 3920. ISO 105 D02/X12. JIS L0849. M&S C8/C8A, NEXT TM6
Measurement Procedure:
1. Sample Preparation:
1.1 The sample and standard white rubbing cloth must be conditioned in a constant temperature and humidity environment.
1.2 When the sample has multiple colors, ensure that all colors are rubbed.
1.3 If the area of each color is large enough, separate samples must be taken.
1.4 Cut the sample and perform both dry and wet rubbing tests, ensuring that all colors are rubbed.
1.5 If the front and back of the sample are made of different materials or colors, both sides must be tested for rubbing color fastness.
1.6 Do not repeat dry and wet rubbing tests on the same part of the sample.
2. Dry Rubbing:
2.1 Place the sample flat on the abrader covered with sandpaper, aligning the length of the sample with the instrument's stroke. Secure the sample to the pressure plate, ensuring that the sample is clamped flat. 2.2 Secure the standard white friction cloth to the abrasion head, secure it with a spring clip, and gently place the abrasion head on the specimen.
2.3 Ensure that the specimen does not slip or wrinkle during abrasion.
2.4 Place the abrasion head on the specimen. Turn on the power and turn on the POWER button. Set the number of tests.
2.5 Press the START button to begin the test. When the number of tests reaches the set value, the instrument automatically stops.
2.6 Remove the standard white friction cloth and compare and rate using a color chart.
3. Wet Abrasion:
3.1 Completely soak the standard white friction cloth in distilled water.
3.2 Remove the cloth and squeeze it between filter paper to maintain a certain moisture content.
3.3 The remaining steps are the same as for the dry abrasion test described above.
4. Result Processing:
4.1 Before rating, gently remove any loose lint from the abrasion cloth with transparent tape. 4.2 Place three layers of unused white abrasion cloth under the abrasion cloth to be evaluated. Assess the staining level of the abrasion cloth using the standard gray scale for staining.
5. Test Report:
5.1 Reporting Standard Method
5.2 Report both dry and wet abrasion results separately.
Care and Maintenance
1. Regularly apply lubricant to the transmission mechanism joints to ensure smooth rotation.
2. Apply a lubricant such as butter to the stainless steel groove on one side of the base.
3. The counter is located on the upper part of the instrument and is more susceptible to damage. Avoid heavy objects from impacting it during use.
4. The stainless steel groove and stainless steel plate on the base are both glued together and inspected for reliability before shipment. However, they may fall off due to impact or prying with sharp objects. Operators should exercise caution.
5. The friction head is made of plastic and is factory-polished to ensure there is no gap between the head and the stainless steel plate. Avoid rubbing the head directly against sandpaper. This can easily cause the head to wear and become uneven. Large gaps between the head and the steel plate can result in uneven pressure on the specimen, affecting test results.
