Remember that this is for DS-1 4th Edition; there's a new 5th Edition available! That means there's a new DS-1 Standard and a new 5th Edition app to upgrade to!

The DS-1 standard is the industry's premier inspection standard, showing the inspector how to find problems and the buyer how to get good results. This app doesn't give you the entire standard, but it allows you to quickly and easily find the requirements from the "Inspection Tables" tab for your components. That includes acceptance criteria for tubes, bodies, API connections, and all the proprietary connections included in DS-1.
