一、概述1.测量依据JJG343-2012《光滑极限塞规检定规程》。2.测量环境条件室温:(20±2)℃,每小时的温度变化为0.5℃,湿度:30%RH~70%RH。量块和被测塞规的温度恒温时间为3h。3.测量设备量块:测量范围为(0.5~100)mm,准确度等级:3等。立式光学计:测量范围为(0~180)mm,最大允许误差:±0.25μm。4.被测对象光滑塞规,标称尺寸:20.00mm;50.00mm。
First, an overview 1. Measurement based on JJG343-2012 “smooth limit gauge regulations.” 2. Measurement of environmental conditions Room temperature: (20 ± 2) ℃, hourly temperature change of 0.5 ℃, humidity: 30% RH ~ 70% RH. Measuring block and the plug gauge temperature thermostat time is 3h. 3. Measurement equipment measuring block: measuring range (0.5 ~ 100) mm, accuracy grade: 3 and so on. Vertical optical meter: measuring range (0 ~ 180) mm, the maximum allowable error: ± 0.25μm. 4. The measured object smooth plug gauge, nominal size: 20.00mm; 50.00mm.
