The identifier B151 usually refers to ASTM B151, a material specification for copper-nickel alloy rod and bar included in the ASME BPVC Section II, Part B, or ANSI/PLASTICS B151.1, a safety standard for injection molding machinery. ASTM B151-20 covers copper-nickel-zinc and copper-nickel alloys, while the ANSI/PLASTICS B151.1-2017 standard defines safety requirements for plastics injection molding machines. Official copies are available via the ASTM International website or the ANSI Webstore .

While the core principles of guarding remain consistent, modern updates to the B15.1 standard typically focus on: The identifier B151 usually refers to ASTM B151,
Materials and Construction: Guidelines on the types of materials (e.g., expanded metal, solid sheet) that are acceptable for building safety guards. This series of standards (often mistakenly cited with
One of the biggest changes made the mechanical safety device (commonly called a "jam bar" or "drop bar") optional for machines built specifically to the 2017 standard. ISO Alignment:
ASME B15.1 is a standard published by the American Society of Mechanical Engineers (ASME) that provides guidelines for the design, construction, testing, and maintenance of safety devices for safeguarding machinery. The standard is titled "Safety Devices for Safeguarding Machinery."
This standard is part of the ASME Boiler and Pressure Vessel Code (BPVC) Section II, Part B . It is identical to and establishes requirements for copper-nickel-zinc (nickel silver) and copper-nickel rods and bars.
