There are a lot of ISO specs when it comes to GD&T, and this saves from having to list all of them.ĭoes this only cover ISO GD&T standards, or is it the wide range of ISO specs?īasically my question is in relation to the application of GD&T is knowing how to differentiate when you have to apply ISO 1101 or ASME Y14. It could reference a completely different ISO specification for something unrelated, and technically then ISO 1101, and a whole host of ISO specs are invoked. There are enough GD&T books and reference material explaining Y14.5 on the market. once per 10 years/ISO standards more frequently. So it doesn't have to say interpret drawing per ISO 1101. ASME Y14.5 - Y14.5 is a user-friendly, one book/ISO is a matrix of standards, Y14.5 is revised approx.

ISO only requires one ISO specification to be listed on the drawing, and then ALL ISO specifications are invoked.

The survey results on the usage of ISO GPS and ASME Y14. ASME, - ISO, - Din ASME Standards ASME Y14.5 Dimensioning and Tolerancing ASME Y14.5M-1994 Dimensioning and Tolerancing ASME Y14. Both standards require the drawing to state that it is to be interpreted per that particular standard. ASME Y14.5 to the ISO GPS system is important for industry.
