IULTCS Rubbing Fastness Tester TF414
Rubbing Fastness Tester, to determine the color fastness to rubbing. IULTCS Rubbing fastness Tester complies with ISO11640, EN 344, SATRA PM 173, etc. You can contact us if you have any problems when you do rubbing fastness test.
IULTCS Rubbing Fastness Tester, designed to carry out a rub fastness test on the surface of leather to determine the amount of ‘marring’ of the leather surface or the finish and to assess the amount of colour transferring from the sample to the rubbing pad under dry or wet conditions.
The unique design of IULTCS Rubbing Fastness Tester allows reliable and stable test result.
Impact appearance and construction design offers a good shape and convenient operation, also allows a long life time without repairing.
Available with a piece of 500g loading weight, thus allows a test with 500g or 1000g loading.
Equipped with an extension device so samples can be extended at a required rate.
Two models of single and double test position are offered.

How to ensure the accuracy of the test results of the color fastness to rubbing?
1.Before testing, we should carefully check whether the friction surface of the friction head is smooth, otherwise, the stain on the friction cloth will appear abnormal phenomena of different colors inside and outside.
2.It must be reliable and cannot be loosened when the friction cloth is fixed on the friction head, otherwise the color spot of the friction will not be round.
3.The surface of the friction head should always be in a relatively parallel contact with the surface of the specimen. When the friction head is improperly installed or the thickness of the specimen varies greatly, the both contact surface will be changed. At this time, the grommets on the friction head should be appropriately increased or decreased to adjust the position of the friction head.
4.When the friction cloth is fixed on the friction head, the friction head should be carefully placed on the specimen so as not to increase the stain degree accidentally. This is especially true for wet friction tests.
Q: Do you have a device for testing color fastness to cycles of to-and-fro rubbing (ISO 11640 standard)?
A: Yes, we do. The IULTCS Rubbing Fastness Tester TF414 is exactly what you want.
Q: Do you have a device for testing the resistance of a material (leather) to wet friction (Russian GOST 13869-74 standard)？
A: No, we haven’t this standard.
