Different limits for new and worn gauges

[Daniel_R]

Hello everybody
I have an issue with GO thread gauge calibration by ISO 1502.
The calibration report contains different limits for new and worn gauges, but I cannot find nothing about it in the standard…
Will be very grateful for any information regarding this subject.
