Description and Specification for Lab Tenders
Color Fastness Tester For Testing Lab Workshop.Â
Color Fastness Tester - For Testing Lab The Color Fastness Tester is constructed on a rigid fabricated frame. Rubbing is carried out by rotating a felt pad against a test specimen placed on an anvil. The felt pad is held in a rotating holder with the help of three sharp needles and can be raised and lowered with the help of a lever to bring it in contact with the test specimen. Motion to the felt pad is given by an AC synchronous motor and belt-pulley arrangement. The sleeve in which the rod carrying the rotating holder slides is mounted on two ball bearings to give it a long and trouble-free running life. Weights are provided to apply the specified forces on felt pads for both dry and wet rubbing.The test specimens are normally kept on a flat platform under the rotating felt pad. However, for testing of finished products, provision has been made to replace the flat platform by a small circular anvil that can accommodate various finished products like shoulders of garments and shoes. A four-digit electronic counter with re-set counts the number of abrading rubs of the felt pad. The counter operates only when the felt pad is lowered on to the test specimen.The tester is finished in shore blue metallic painting and bright chromium or zinc plating to give it a corrosion resistant finish. civil lab equipments manufacturers
