Design Review Checklist for Section VIII, Division 1

This checklist has been prepared by CIS GmbH. It refers to vessels made of carbon, low alloy, high alloy steels and nonferrous metals. For other types of construction see the ASME Code. However, this checklist is intended to be used for help and guidance only, it cannot replace profound knowledge of the Code.
