Standard for Rounding Measurements for Labels

R

Good Morning,
I think i already know that this does not exist but i just want confirmation.
Has anyone come across a standard that discusses labeling and rounding of measurements. For example you have a part and it measures at 11.8" and 299.72 mm but you want to put a whole number on the label like 12" & 300mm Are there guidelines for this?

TIA

Re: Standard for Rounding

What is the reason for putting "whole numbers" on a label?

Personally I have never see a standard address rounding of decimals or fractions for labeling.

Can you briefly describe your product? Because you posted in a medical Forum, there are FDA rules for this.

I'm not aware of specific FDA labeling rules addressing this issue. There are though general provisions in the regulations addressing issues such as misleading statements. It all comes down to the significance of such rounding.

This to me seems a specific requirement, and is not addressed in any standard.
It depends upon the criticality of the matching part (in case of some moulded cutout dimensions where the label has to be placed) OR depends upon your specific control which has to meet the cutting die tolerance.
In general, if you have the space then you can feel free to round it to the nearest full number.

That's what I meant. :yes:

But we still don't know the OP's industry/product... :nope:

The closest you will get to an answer is ASTM E29-08 Standard Practice for Using Significant Digits in Test Data to Determine Conformance with Specifications.
