This bursting strength tester use pneumatic method, meet multinational standards and equipped with several changeable test clamp. The simple interface touching screen controller is easy and simple to handle. The specimen was clamped firmly by the pneumatic force which can also save effort. The test cover was made up of high-transparent glass with LED light inside which can observe the specimen easily. The Bursting Strength Testing Machine can induct the burst automatically which is much more sensitive and reliable. The bursting distension can go up to 75mm.
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.
Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed. Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface. Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.
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. See more details on https://www.gesterinstruments.com/.
