Calibration of standard hardness blocks3 hardness tester classificationAccording to the different geometric shapes of the pressure pin and the spring of the elastic modulus of the nominal value of the different combinations of hardness tester is divided into A type, B type and Type C three types. The hardness of the hardness of the various types of needle shape and force spring elastic modulus nominal in Table 1. Table 1 hardness model, pressure needle shape and force spring elastic coefficient nominal value Hardness gauge type Needle shape Force spring elasticity coefficient nominal value N/mm A Cone 75 B cylinder 145 C cylinder 754 General requirementsBefore the test, the hardness tester should be checked to ensure that. a) the application of test force, the pressure pin movement should be flexible, no friction and jamming phenomenon; b) The pointer of the analogue indicating device shall be sensitive, without beating and jamming; the display of the digital indicating device shall be clear and complete, Continued and stable; c) the tip of the pressure pin should be located in the center of the small hole of the pressure cylinder. When the pressure needle falls, the tip of the pressure needle should be at the highest point of the arc of the anvil, See the offset; d) When holding the handle, so that the end of the pressure cylinder on the anvil, the pressure between the end of the needle and the anvil should be no visible light gap. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32660.2-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32660.2-2016_English as soon as possible, and keep you informed of the progress.
