Hi All,
As per J444,3.1.1.1 and 3.1.1.2, the shaking speed shall be 270 to 300rpm and taps per minute shall be 140 to 160.
Would like to know how to calibrate the Ro-tap machine to NADCAP standard? As J444 is a requirement and there's no standards detail the Ro-tap performance.
Calibration has also become the local site responsibility.
Thanks!
