ASME Standard for Leading Zeroes in we

ASME Standard for Leading Zeroes in we

ASME Standard for Leading Zeroes in we

(OP)
First time posting so forgive me if I missed any rules I should be following.

We follow ASME Y14.100 and Y14.5 at my work and do our best to keep up to date on all the different standards. We are making it a point to add typical weights and acceptable ranges for parts to keep quality happy.

Is there any standard that specifies leading zeroes should be added to weights less than 1 unit? Or does this follow inch dimensioning rules where the leading zero is left off?

For example: 0.1 LBS. or .1 LBS.

Any help or direction is appreciated!

RE: ASME Standard for Leading Zeroes in we

14.5 doesn't cover weights; I don't have 14.100. I prefer the leading zero as sometimes the decimal point is tougher to see. I don't feel like anyone is running out of zeros, so it's not like saving whales.

Here's how other areas of publication use it:

and this one that supports it all

RE: ASME Standard for Leading Zeroes in we

in that case would it not be better to use ounces

RE: ASME Standard for Leading Zeroes in we

It's up to your company rules.
But, for 0.1 LBS. or .1 LBS, I would use 0.1. If you use .1, it can easily be mistaken for 1. Decimal points can sometimes either not print dark enough, or blend with background.

Yeah, neither of those standards really talked about weights and the preferred way of writing them. I am definitely leaning towards the inclusion of the leading zero but the last thing I want to have to do is rework a drawing because there happens to be a correct way due to some obscure ASME standard and someone being a stickler for the rules.

We do use ounces when the weights get lower but the same issue still applies for the really small parts.

That's what I figured. I thought somewhere there might be some standard since there seems to be a rule for just about everything but that seems to not be the case.

RE: ASME Standard for Leading Zeroes in we

I like leading zeroes for the same reason I like the Oxford comma. It hurts nothing, combats ambiguity, and just plain looks better.
