一、概述1.测量依据JJG1039-2008《D型邵氏硬度计》检定规程。2.环境条件温度:(23±5)℃,湿度:≤80%RH。检定前被检硬度计及使用的检定器具,应在同一环境条件下至少放置1h。3.测量标准邵氏硬度计检定装置,最大允许误差为±50mN。4.被测对象D型邵氏硬度计,测量范围为(20~100)HD。5.测量过程根据JJG1039-2008,进程试验力误差为其主要的技术指标。使D型邵氏硬度计压针试验力施加到邵氏硬度计检定装置上,试验力的检定应在硬度计示值(20~100)HD使用范围内均匀分布地选取3~5个点进行,其试验力的进程允许偏差为±445mN。
I. Overview 1. Measurement based on JJG1039-2008 “D-type Shore Hardness Tester” test procedures. 2. Environmental conditions Temperature: (23 ± 5) ℃, humidity: ≤ 80% RH. Pre-test hardness and the test instrument used inspected should be placed in the same environment at least 1h. 3. Measurement standards Shore hardness tester, the maximum allowable error of ± 50mN. 4. D object to be measured Shore hardness tester, measuring range (20 ~ 100) HD. 5. Measurement Process According to JJG1039-2008, the process of test error as its main technical indicators. The D-type Shore hardness tester pressure pin test force applied to the Shore hardness tester, the test force test should be displayed in the hardness tester (20 ~ 100) HD use evenly distributed within the selection of 3 to 5 points , The test process of the allowable deviation of ± 445mN.
