扭矩扳子示值重复性检定分析数据

扭矩扳子广泛用于对拧紧工艺有严格要求的装配线，使产品各个紧固件扭矩值一致，生产出来的产品质量有保障。检定分析得出的结果来判断扭矩扳子示值重复性准确度等级，有助于判断市场上扭矩扳子的的整体质量，为政府监管、相关单位购买提供参考和技术支撑。1数据采集：名称、型号、送检单位、编号、检定点、按照扭矩扳子检定规程要求测得的3个检定点顺时针方向实测值等；2数据处理：(1)平均值=(顺时针方向实测值1+顺时针方向实测值2+顺时针方向实测值3)/3；(2)示值重复性=（检定点-平均值）/平均值*100；(3)示值重复性准确度等级，规程规定示值重复性为±1%的为1级、示值重复性为±2%的为2级、示值重复性为±3%的为3级、示值重复性为±4%的为4级、示值重复性为±5%的为5级、示值重复性为±6%的为6级、示值重复性为±10%的为10级，三个示值重复性需同时满足某一等级且以等级高的为最终等级，例如本条示值重复性1为1.5、示值重复性2为0.3、示值重复性3为0.6，示值重复性等级符合2-10级，最终等级为最高等级2级。

Torque wrenches are widely utilized in assembly lines with strict tightening process requirements, to ensure consistent torque values for all fasteners of products and thus guarantee product quality. Judging the accuracy grade of torque wrench indication repeatability based on calibration analysis results helps assess the overall quality of torque wrenches on the market, providing reference and technical support for government supervision and procurement activities of relevant entities.
1. Data Collection: Name, model, the unit submitting for inspection, serial number, calibration points, clockwise measured values at 3 calibration points tested in accordance with the torque wrench calibration procedure, etc.
2. Data Processing:
(1) Average value = (Clockwise measured value 1 + Clockwise measured value 2 + Clockwise measured value 3) / 3;
(2) Indication repeatability = (Calibration point - Average value) / Average value × 100;
(3) Indication repeatability accuracy grade: The calibration regulation stipulates that indication repeatability of ±1% corresponds to Grade 1, ±2% to Grade 2, ±3% to Grade 3, ±4% to Grade 4, ±5% to Grade 5, ±6% to Grade 6, and ±10% to Grade 10. All three indication repeatability values must simultaneously meet the requirements of a certain grade, and the highest qualified grade shall be taken as the final grade. For example, if the first indication repeatability is 1.5, the second is 0.3, and the third is 0.6, the indication repeatability grades fall within Grades 2 to 10, so the final grade is the highest Grade 2.
