SPI and ANSI publish new machinery safety standards

April 23, 2014

The Society of the Plastics Industry Inc. and American National Standards Institute have revised two standards and extruders and vertical injection molding presses, and issued a new standard for blow molding machines.

ANSI/SPI B151.31-2014, Safety Requirements for the Manufacture and Care of Blow Molding Machines is a new standard addressing the safety requirements for both extrusion and injection blow molding machines. It replaces two separate standards, ANSI/SPI B151.15-2003 and ANSI/SPI B151.21-2003. Both of those have been formally withdrawn as American national standards.

The two revised standards are: ANSI/SPI B151.7-2014 Safety Requirements for Extrusion Machines and ANSI/SPI B151.29-2014 Safety Requirements Vertical Clamp Injection Molding Machines.
