Testing of thread ring gauges
The pitch diameter and tolerances given in the gauge standards are not applicable for newly fixed thread ring gauges, if these ring gauges are, as is customary,
manufactured according to test plug gauges. In case the rings are directly measured in the pitch diameter, the specified sizes and tolerances given in the
standards are applicable. In such a case, this must be explicitly stated in the order for thread ring gauges.
A subsequent complaint or claim will not be accepted.
Calibration:
Thread gauges can be supplied with a works calibration certificate or DKD calibration certificate from an accredited laboratory.
