ANSI y 14.5 question

[Thee Dragracer1951]

Is there, in ANSI Y 14.5 anything about least significant digits? In other words if a part is tolleranced as X dim +.000 -.002, Can it be rejected for being .0002 oversize?

 

No opinions please. I need to know what ANSI Y 14.5 says about this

Thanks

This really is a matter of interpretation. The ANSI std. gives rules by which to construct the tolerances and mathematical formula for interpreting those tolerances. However, nowhere can I find a rule for this situation.

 

This should probably be negotiated with the customer.

 

HTH.

Significant digits are not addressed in ANSI Y14.5. I think tolerances are absolute, .0002 > .000 no matter how many times you count.

 

Think of this another way. What would be your response if they were .0002 undersize and the inspector/client complained that was too close to .000?

Just curious, I've heard arguments for both sides. We just got into a discussion and I couldn't find my copy of Ansi 14.5
