The American National Standards Institute's newest revision contains significant changes from the previous 1988 document and includes:
- A flow chart that aids the reader with navigating the standard – more definitions
- Responsibility outline of the supplier, the user and personnel (employees)
- New information on hazard control to help supplier and user in controlling the hazards associated with P/M press operation and reducing the risk to an acceptable level
- New requirements for control reliability
- Consideration of hot powder systems
- Recognition of die set presses where the entire die set is removable
- New guard opening table
- New annex that provides information on task-based hazard identification to help with risk assessment process.
