Engineering Drawing: Tolerance ISO Grade 13

[dhanish.ab]

Hello Everyone,

I have been tasked to bring the existing drawing into our current system. On doing so i am hurdled with issues in Tolerance.

Old drawing points in drawing title block about the dimension calls out for ISO STANDARD TOLERANCE GRADE 13. With all liner dimension. I assume all dimension should refer some reference.

Please note there is no other mention of tol. in tittle block apart from this

Currently we follow ISO 8015 standard, We define the position tol. and profile tol. and apply basic dimension and GD&T

Can any one guide on how do i go about it. I have found very little documents on ISO grade 13 and finding it hard to interpret the same.

I just want to make sure i callout the correct value when i draft to out current drawing standards.

Any suggestion will be of great help

No idea, but when was this drawn/released?

Wild guess at best - are they refering to IT13 in ISO 286 ?

@rothers,

I assume it to be same. unfortunately i have no way to contact anyone to double check. Just dont want to fault any tol.

i am currently referring this table.
