ASTM D4060 Taber Abrasion Tester Uses and Factors to Be Considered: Taber Abrasion is used for measuring the wear resistance of organic coatings applied flat, rigid test samples. ASTM D1044 is used for transparent plastic materials to evaluate their capacity to maintain their optical properties, upon typical, wear to be expected while in service. Abrasion resistance to Taber Abrasion is usually measured as a weight or a coating thickness loss after a given number of cycles. Each arm, by default, is loaded to apply a 250 g. pressure on each wheel. Depending on the product/specification used, this weight can be increased to 500g or 1000g. The abrading wheels are available in different grit for a more or less abrasive action.
How to maintain the universal testing equipment? The part of the utm electronic universal test instrument is often wiped clean and kept clean. Please wipe with electroplating oil to prevent rust and light. Please add lubricating oil to the power screw and screw part to ensure the transmission is sensitive. the panel, please wipe with a dry cloth, to prevent water, so as not to damage IC electronic parts. Please fix all fixtures and fittings and wipe the anti-rust oil to prevent rust.
Reagent Preparation: Prepare corresponding reagents according to different test standards and keep them as standby. If sodium perborate is required in the test, the preheating temperature shall not exceed 60℃ when preparing the solution, and it shall be used within 30 minutes at most to prevent the loss of oxidant. Solution Warm-up: Put the specified volume of solution and a specified number of steel balls into the stainless steel cup, put the stainless steel cup into the launderometer for a few minutes, preheat to the specified temperature. Then put in the prepared sample for test.
Application of Universal Testing Machine: This types of tensile testing machines is designed for conducting tensile, compression, bending, shearing, bonding strength, peeling, tearing and other tests for shoes, rubber, plastic, leather, metal, nylon line, fabric, paper, aviation, packaging, construction, petrifaction, electrician, vehicle and other materials. It is a basic equipment of quality control, receiving inspection, physical test, mechanics research, material development. Find even more information at https://www.gesterinstruments.com/.
