INTRODUCTION J443 – Procedures for Using Standard Shot-Peening Test Strip, was first approved in January, 1952. As an SAE Recommended Practice document the principles that it enshrined were widely adopted by the then emerging shot peening industry. With accumulated experience and technological advancements several revisions became necessary. These were made in 1961, 1984, 2003 and 2010. A further revision is a “Work In Progress.” J443 is an important, definitive, guide to shot peening intensity measurement. This article attempts to trace the influence that the evolution of J443 has had on shot peening intensity measurement. Future developments will have to take into account new technology and a more universal input of ideas.
