INTRODUCTION

International Truck Division has adopted an amended version of the ASME Y14.5M-1994 dimensioning and tolerancing standard (as amended by this addendum) for use on all product engineering documentation.

Note: This addendum is a modification of the 1997 addendum adopted by General Motors Corporation, Chrysler Corporation, and Ford Motor Company. Permission to use and modify this agreement was granted by Alex Krulikowski –GM Team Member of the US Car GD&T Team.

This addendum is created to address the following areas:

1. Select an option from ASME Y14.5M

2. Clarifying a concept from ASME Y14.5M

3. Discouraging the use of a concept from ASME Y14.5M.

4. Including a concept not covered by ASME Y14.5M.

Proposals to revise this addendum are evaluated on an annual basis. When a revision is published, the year of publication will appear in the title of the addendum.

All other standards referenced in ASME Y14.5M have not necessarily been adopted and should not be assumed to be invoked automatically. Current company standards will take precedence unless otherwise specified.

If a conflict exists between ASME Y14.5M-1994 and ASME Y14.5.1M-1994, ASME Y14.5M-1994 is to be used.

Note: Where product engineering documentation is based on this addendum, this fact must be noted on the documentation or in a specification referenced on the document.
