What is the proper way to use a GO NO/GO guage?

What is the proper way to use a GO NO/GO guage? I have a
1 1/2 lbs go guage that I'm putting into a plastic part. When I put it in it does not easley come out. Is the fact that it's going in OK?

With the little information you have given it would be hard to say. What kind of tolerances do you have on the part? How stable is the parts form? Could it be you have created a vacuum when you placed the gauge into a blind hole?

Murban,

I agree with Sirlard, you need to provide more information. My general advice is to consider the use of the plastic part. If the go-gage goes in snugly, would it be okay if the part that goes into this hole in the final application went in that snugly? If you're not sure, a talk with the customer may be in order. Did this help?

As you are using a weight I assume you are testing an insertion or retention force in the part. Judging by the fact that you appear pleased that the part retains the weight I imagine its a retention force you are checking.

The 'go' in such cases I would image is a retained weight, and the 'no go' would be a dropped weight.

Only guessing though !
