用这种测试机测定的硬度值以L=100 V_R/V_A计量。测试时测量头在弹力作用下冲击被测面,然后弹回,L值即为弹回速度V_R除以冲击速度V_A所得的商乘以系数1000而得。若V_A为常值,则L值只取决于测量头的回弹速度,而回弹速度是随被测材料的硬度增加而增加。EQUOTIP测试法可与其他常用的静止痕硬度值(HB、HV或HRC)转换,也可用肖氏硬度法
The hardness value measured with this tester is measured at L = 100 V_R / V_A. During the test, the measuring head will impact on the measured surface under elastic force and then rebound. The L value is obtained by multiplying the bounce velocity V_R by the impact velocity V_A by a factor of 1000. If V_A is a constant value, the value of L depends only on the springback speed of the measuring head, and the springback speed increases as the hardness of the material under test increases. EQUOTIP test method can be used with other commonly used static hardness test values (HB, HV or HRC) conversion can also be used Shore hardness
