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.

Correct use of computerized universal testing machine: When opening the clamp to take the sample, pay attention to the clamping distance of the sample, not too much or too little. When the tensile testing machine and the microcomputer are connected, the operation must be carried out according to the program requirements. It is strictly forbidden to operate the program due to illegal operation; The parameters to be printed check whether the printer has paper and replenish it in time before printing. After the operation is completed, shut down the tensile testing machine for rubber according to the program requirements. It is strictly forbidden to cut off the power directly.

Gauge length and tension speed presettable; Able to set pre-tensile force; Many kinds of clamp are selectable according to requirements test standards, including pneumatic clamps. Textile fabric, such as bedsheets, clothes, etc., a lot of them will lose color after washing, some products fade seriously, even after washing many times, there will still be discolored. Test Preparation before Color Fastness to Washing. What test standards are there? Color fastness to washing is one of the common test items for textile dyeing fastness, which is mainly used to test the fastness of fabric clothing and home textile products after one or more times to simulate the dyeing after household washing and commercial washing. There are three common standard: AATCC 61, ISO 105 C06, GB/T 3921.

Significance and Use: Fabric Pneumatic Bursting Tester method for the determination of diaphragm bursting strength of knitted, nonwoven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses. universal testing machine compression test : tensile test generally involves clamping the two ends of the material sample on two fixtures separated by a certain distance. The two clamps separate and stretch the specimen at a certain speed. The change in stress on the sample is measured until the sample is destroyed. The tensile test of the tensile machine is one of the most widely used methods for studying the mechanical strength of materials, and it is necessary to use constant speed motion.
