Reference standard for leather rubbing color fastness tester

 

As a modern technology enterprise integrating R&D, manufacturing, sales, training, and service, Standard Group (Hong Kong) Co., Ltd. is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, and environmental climate aging of materials. Non-standard customization is also acceptable. Targeted tests can be carried out according to customer requirements before purchase to ensure that the purchased instruments are suitable.

 

Reference standards:
 

- ISO 11640 Leather. Color fastness test. Colorfastness to periodic reciprocating friction
 

- QB/T 4961 Leather friction color fastness tester
 

- QB/T 2537 Leather. Color fastness test. Reciprocating friction color fastness
 

- ASTMD 5053 Standard test method for the color fastness of leather rubbing discoloration
 

- ISO 20433-2012 Leather. Color fastness test. Colorfastness to friction
 

- JIS K6559 Leather color fastness test
 

 

Main parameters:
 

1. Test head area: 15mm×15mm
 

2. Weight block mass: 500g, 1000g
 

3. Total mass of the test column after loading: 1000g
 

4. Friction stroke: 37mm
 

5. Friction frequency: 40 times/min
 

6. Reciprocating times: 0~999900

 

Main features:
 

1. Used for friction color fastness tests on leather surfaces to determine the degree of damage to the leather surface and the amount of color transferred from the sample to the friction pad. This instrument can be used for dry friction tests with friction pads, and can also be used for wet friction tests with wet friction pads treated with distilled water or sweat.
 

2. The wear resistance of the upper sole material can also be tested with this instrument. This type of test can be performed by replacing the felt pad with a small special-shaped rubber friction pad. Normal wear, especially when the wearer crosses his legs or the sole of one shoe is placed on the other shoe, can cause wear on the shoe material.
 

3. Simple operation. The sample is placed on the test platform and fixed with the provided clamp. The matching knob and percentage scale on the machine test table are adjusted to produce pre-tension. The square friction piece is mounted on the clamp at the end of the friction head, and the friction head is lowered to the sample surface. When the instrument reaches the preset cycle, the counter equipped with the machine can stop the machine.
