introduction：(1)Temperature conditions at the time of measurement The ambient temperature at the time of measurement is specified as20℃，amongINAbearing、Gauge block、The temperature of standard parts and measuring instruments must be the same，The above method of placing them on the same metal plate is the fastest way to achieve the necessary temperature balance，Otherwise it can take hours or even days to achieve such a balance。 To get the correct measurement，Foreign countries rely on the mechanization of measurement to avoid human contact with these objects，Or wear heat-proof gloves to operate。 (2)The measurement area is specified towardsINAMeasurement of bearing inner or outer diameter，In China, it is stipulated that the measurement should be made in the area with a maximum chamfer coordinate on each side leaving the southern side of the ring，In foreign countries, it is usually prescribed to measure in the area where the two ends of the ring are each twice the chamfer coordinates。 (3)Specification of size basis The m
