SAE J442_202205

This SAE Recommended Practice defines requirements for equipment and supplies to be used in measuring shot peening arc height and other surface enhancement processes. It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. Guidelines for use of these items can be found in SAE J443 and SAE J2597. The scope now includes the intent of this document as a guide to standard practice. Test strip requirements are now centralized in this document to prevent misinterpretation. This resulted in a high-grade test strip being added to this document in preparation for test strip requirements being removed from AMS2432. Figures 1A and 1B were re-drawn to support two grades of strips. Tables 1A and 1B were added to clarify test strip requirements. A transition period of 18 months has been noted to allow non-conforming strip manufacturers to make acceptable strips. Other changes include removal of conflicting and redundant text. Figure 3 was re-drawn to add inch dimensions for reference while maintaining dimension format/method. The analog gage option was removed from the Figure 3 notes due to requirements outlined in 3.3.1. Side positioning posts that center the test strip along its longer dimension are now required. Figure 4 was re-drawn to correct poor dimensioning in Detail A. Figure 2 was re-drawn to match format of other new figures.
