I have sent a thread plug gauge for calibration (1/4"x19 BSP). As per standard IS 2643,
GO PCD =12.304 to 12.314 with wear limit 12.295
NO GO PCD 12.426 to 12.436 with wear limit 12.421
Measured values using length measuring machine is
GO PCD = 12.298 to 12.302
NOGO PCD = 12.428 to 12.450
Nogo is +0.014 in plus side.
Do I have to reject the thread plug gauge?
