There is a fundamental difference in the way that the ISO and ASME GD&T standards look at a single feature on a drawing. (Some examples of hard gages are pin, ring, and thread gages.) ISO standards are seen to be more favorable to inspection procedures using coordinate measurement machines and systems. Table 1:Р’В ISO Standards for Manufactured Part VerificationР”В«ecause of these differences, the ASME standards are often seen asР’В having a preference forР’В hard gaging. ISO GPS standards includeР’В eightР’В standardsР’В for dimensional measurement equipment (gages), andР’В three standards for coordinate measurement machines (CMMs),Р’В shown below in Table 1.Р’В There is also aР’В ten-partР’В standard, ISO 25178, regarding the measurement of surface texture. ISO 14253Р’В (this standard is broken up into six parts)Р’В deals with verifying conformity or non-conformity of a part being inspectedР’В usingР’В the measurement equipment. ISO 14978Р’В defines the general requirements and calibration requirements forР’В GPS measurement equipmentР’В (such as micrometers, calipers, and gauge blocks). In addition to dimensioning and tolerancing,Р’В ISO GPS standards also include many specifications for the design of different types of gages, acceptance tests, and calibration of coordinate measurement systems. This helps clarify how the gage tolerances ensure that the parts are made to spec. This gage creation document includes many figures showing parts and their corresponding gages. ASME Y14.43Р’В gives dimensioning and tolerancing principles for gages and fixtures used to verify the manufactured parts. This is addressed in a separate document, ASME Y14.43. It does not include specifications for verifying the dimensions of the manufacturedР’В part. Worldwide Usage of GD&T Standards What are the major differences between the ISO GPSР’В standards and ASME Y14.5? Standards for Manufactured Part VerificationР”Р„SME Y14.5 is a specification for the dimensions and tolerances on a drawingР’В of a part only. Fifty-six percent of international participants indicated that their company uses ASME Y14.5. The results of this survey showed that 86% of US participants used ASME Y14.5 in their company.

Sixty-three of the participants were from the US, and 70 were from other countries. One hundred and thirty-three people from varying industries, company sizes, and 27 countries responded to the survey. In fact, a recent surveyР’В by Alex KrulikowskiР’В showed that ASME Y14.5 may be used more often than ISO GD&T standards. Yet,Р’В a majority ofР’В American companies and many international companies use the ASME GD&T standard, ASME Y14.5, as their GD&T standard, rather than ISO standards. It allows a drawing of a part to be created in one country and manufactured in another without confusion. Having a global specification where the requirements are shown using symbols, rather than notes,Р’В has a major benefit. ISO GPS is the international dimensioning and tolerancing standard. calibrationР’В ofР’В the measurement instruments in verifying part geometry.The ISO GPS family of standardsР’В cover theР’В requirements for:

ISO national members nominate members to the technical committees. ISO technical committees include both standards and industry experts. This committee was formed in 1996 under the leadership of Danish Standards, the national organization of standards in Denmark. ISO geometrical product specifications (GPS) are created and maintained by the ISO Technical Committee 213Р’В (ISO/TC 213). The ISO national standardsР’В body for the United States is the American National Standards Institute (ANSI). Only one national standardsР’В body is allowed per country.

Each member body is the leading standards organization in their country. It wasР’В founded in 1947 to develop and publish international standardsР’В andР’В is madeР’В upР’В of 164 national standards bodies. The International Organization for Standardization (ISO) is an independent, non-governmental internationalР’В organization.

ISO Geometrical Product Specifications (GPS) In this article, we are going to discuss the ISO Geometrical Product Specifications (GPS) family of standards and their differences from the ASME GD&T standards. These two systems have many similarities and a few major differences. The two most popular are published by ASME (American Society of Mechanical Engineers) and ISO (International Organization for Standardization). There are many standards that define requirements for GD&T.
