Thus, when using millimeters you cannot have a title block tolerance method which relies on the number of decimal places (unless, I suppose, you ensure that every dimension ends in an artificially induced digit that isn't zero). The drawing cannot display values of 12.00 or 12.000. Unlike inches (which are explained in the subsequent paragraph), when using millimeters it is forbidden to have any extra zeros after the last digit to the right. In the 2009 edition, see paragraph 1.6.1(c) and in the 2018 edition see paragraph 4.3.1(c). RE: General Tolerances Unless Otherwise Stated (Linear/angular) handleman (Automotive) 2 Dec 20 16:31įinglas, if you have a copy of the ASME Y14.5 standard, read the paragraph for millimeter dimensioning. "For every expert there is an equal and opposite expert" The list can unfold virtually indefinitely, but it should be clear that users of metric standards are doing perfectly well without using “trailing zeros” JIS B 0410 – Japanese standard for sheet metal part general tolerances.NF E02-352 – French standard for sheet metal part general tolerances.NF T58-000 – French standard for plastic part general tolerances.DIN 16901 (or newer DIN 16742) – German standard(s) for plastic part general tolerances.

ISO 13920 – general tolerances for weldments: “GENERAL TOLERANCES ISO 13920 – BE”.

ISO 8062 – tolerances and allowances for casting: “GENERAL TOLERANCES ISO 8062 – CT12”.

(This is recommended for small parts with most of the dimensions falling within short range from each other) “UNLESS OTHERWISE SPECIFIED, ALL UNTOLERANCED DIMENSIONS ARE +/- 0.8” Using single tolerance for all dimensions: Recreating in part or in whole Table 1 and/or 2 from ANSI B4.3-1978, or equivalentĦ. “UNLESS OTHERWISE SPECIFIED, ALL UNTOLERANCED DIMENSIONS ARE: Referring to International Tolerance Grade (“extended” version): “UNLESS OTHERWISE SPECIFIED, ALL UNTOLERANCED DIMENSIONS ARE +/- IT14/2”Ĥ. Referring to International Tolerance Grade

“UNLESS OTHERWISE SPECIFIED, GENERAL TOLERANCES PER ANSI B4.3 MEDIUM SERIES APPLY”ģ. Referring to (discontinued) ANSI B4.3-1978: Note: ISO 2768 may have different flavors around the world: “UNTOLERANCED DIMENSIONS PER ISO 2768 –mK-E” The ways to specify general tolerances without resorting to number of decimal digits: Yes, you cannot use the number of decimal places to imply default tolerances in ISO. If you are doing metric dimensions then you can not use the number of decimal places to imply default tolerances in ISO.
