Is it acceptable to have a Ring gauge with minor diameter of the Nogo ring over the upper limit of the specification? Below the data.
Minor diameter specification 0.8829"+0.0007"/-0, measured value 0.883850" , it was out by 0.00025"

Re: Nogo Ring Over the specifiaction limit

Hi there
Please can you confirm if it is a screw ring or plain ring?

From memory, the minor diameter is clearance on a screw ring and does not affect the performance.

If it's your own screw ring, then put a note on the record to "use as is" and carry on.

If it's your own plain ring, then it depends on the use. If it's an air gauge ring, then the new size can be marked and compensation made. If it's a "this gauge should not go over this part" check ring, then it's a scrapper.

The question needs to be asked, why has it worn or changed size?

If it is a calibration of a customers ring, either type, tell them it's wrong and let them worry about it. (also, give them a price for a new one:))

It is a screw ring gauge and its minor diameter was out at the high side of the spec.The supplier asked me to accept the gauge, he explained that the manufacturer practise to make the gauge at high side of the spec to compensate user wear and tear.

But surely wear and tear makes it bigger..
I would expect it to be slightly undersize to compensate for wear.
But as the minor diameter is clearance, it's a moot point...
As you have bought the gauge, I would reject it and get them to make a new one that is correct.
Cheers
Paul
