Understanding the ASME/ANSI B151 Standard for Plastics Machinery
series of standards is the primary regulatory framework ensuring safety and operational efficiency in the American plastics machinery industry. While often searched as "ASME B151," these standards are officially maintained by the Plastics Industry Association (PLASTICS) and approved by the American National Standards Institute (ANSI) Core Focus: Safety and Compliance The B151 standards, particularly ANSI/PLASTICS B151.1
, establish safety requirements for the manufacture, care, and use of injection molding machines (IMMs). They are classified as "Type-C" standards, meaning they address detailed safety requirements for specific machine groups rather than general principles. Key safety areas covered include: Hazard Identification
: Protecting operators from hot plastic spray, pinch points between molds, and high-pressure vapors. Interlocking Systems
: Requirements for safety gates and non-contact interlock switches to prevent accidental machine cycles. Risk Assessment
: Mandating documented risk assessments from both manufacturers and users to identify site-specific hazards. Major Recent Updates The most significant update to the series is the ANSI/PLASTICS B151.1-2017
edition, which introduced several critical changes aimed at global harmonization:
Some sites host "drafts" or "Proposed Revisions." These are not the final, approved ASME code. Using a draft in production is a structural integrity risk.
Mechanical power transmission apparatus (gears, belts, shafts) remains one of the top sources of workplace injuries. Using an outdated
There is no current official "ASME B151" standard. Most searches for this term refer to one of two distinct safety standards: ASME B15.1, which covers general mechanical power transmission, or the ANSI/PLASTICS B151 series, which specifically covers plastics machinery like injection molding machines. 1. ANSI/PLASTICS B151 Series (Plastics Machinery)
This series is the most common modern reference for "B151." It is developed by the Plastics Industry Association and provides safety requirements for the manufacture, care, and use of plastics machinery.
ANSI/PLASTICS B151.1-2017: The primary standard for Injection Molding Machines (IMM). It covers both horizontal and vertical clamp machines .
Key Update: In the 2017 edition, mechanical safety devices (like "jam bars") became optional for horizontal machines if they meet other specific safety requirements .
Structure: Uses a two-column format where the left side lists mandatory "Standard Requirements" and the right provides "Explanatory Information" . Other B151 Standards: B151.21: Safety for Injection Blow Molding Machines . B151.27: Safety for Integrating Robots with IMMs .
B151.29: Safety for Vertical Clamp Injection Molding Machines .
B151.5: Safety for Plastic Film and Sheet Winding Machinery . 2. ASME B15.1 (Mechanical Power Transmission)
Historically, ASME B15.1 (Safety Standard for Mechanical Power Transmission Apparatus) was the standard for safeguarding moving parts like pulleys, gears, and belts .
Status: ASME withdrew as the secretariat for this standard in 2008. Responsibility was transferred to the Association for Manufacturing Technology (AMT) .
Current Reference: It is now typically part of the ANSI B11 series of machine tool safety standards .
Content: Focuses on protecting people from "motion hazards" (rotating or oscillating parts) that are not at the "point of operation" (where the machine actually performs its work) . asme b151 pdf upd
"ASME B151" searches generally refer to either the ASME SB-151 copper-nickel alloy material standard, updated to B151/B151M-20, or the ANSI/PLASTICS B151 safety standards for machinery, including the 2017 injection molding update. The ANSI/PLASTICS B151 series, which covers safety for injection molding and robot integration, is currently undergoing harmonization with ISO 20430.

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.
