Unlike broad safety standards that apply to general industrial machinery, the B151 series is highly specialized. It addresses the unique mechanical actions found in plastics processing, such as:
Ensure existing guards comply with the gap-to-distance ratios specified in the PDF.
Since you likely need ASME B31.1, here is a detailed breakdown.
For companies that need multiple codes:
Rotating shafts, including transmission shafting, countershafts, and underground shafting. Pulleys and Sheaves: Components used in belt drive systems.
Guidelines for complete enclosures to eliminate pinch points.
High-tonnage hydraulic or electric toggles that compress molds. asme b151 pdf
: It defines the precise percentages of copper, nickel, zinc, and other strengthening elements like manganese or iron to achieve desired corrosion resistance.
The standard outlines strict design criteria for physical barriers. Safety guards must meet specific construction and placement rules to be considered compliant. 1. Guard Construction and Materials
