This following study aid helps you learn the content of API RP-578, Material Verification Program for New and Existing Alloy Piping Systems. There will be about 5 questions from this document on the API 570 exam. We do not spend class time on this publication. So it is important that you become familiar with this content in your personal study sessions. The questions in this study aid are in the same order as API 578. The answer key with references is in the back of this guide. It is helpful to read through API 578 before working on this exercise! Questions in Yellow are Open Book Questions! 1.
