ANSI Standards for Machines & Equipment

ANSI Overview

The American National Standards Institute (ANSI) is a private, non-profit organization that administers and coordinates the U.S. voluntary standardization. ANSI's mission is to enhance both the global competitiveness of U.S. business and the U.S. quality of life by promoting and facilitating voluntary consensus standards, and safeguarding their integrity.

Formed in 1918, ANSI oversees the creation and use of thousands of safety standards that directly impact manufacturing businesses in nearly every sector: from industrial machinery to construction equipment, from dairy and livestock production to energy distribution, and many more. ANSI also actively engaged in accrediting programs that assess conformance to standards – including the globally-recognized cross-sector ISO 9000 (quality) program. There are over 9500 ANSI Standards covering a vast rage of areas, topics, industries, processes, machines and equipment.

The membership in ANSI is comprised of Government agencies, Organizations, Companies, Academic and International bodies, and individuals. In total, the American National Standards Institute (ANSI) represents the interests of more than 125,000 companies and 3.5 million professionals.

ANSI is the official U.S. representative to the International Accreditation Forum (IAF), the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). ANSI coordinates U.S. standards with international standards so that American machines and equipment can be used worldwide.

How Does ANSI Apply to Manufacturing?

In simple terms, ANSI represents the voluntary "industry consensus" stardards for best practices.

  • ANSI/NFPA 79 (2015) - Electrical Standards for Industrial Machinery
  • NEC (2014)  - The National Electric Code (also known as ANSI/NFPA 70)
  • ANSI/NFPA 70E (2015) - Standard for Electrical Safety Requirements for Employee Workplaces
  • ANSI Z535.4 (2011)  - Product Safety Signs and Labels
  • ANSI Z535.6 (2011) - Product Safety Information in Product Manuals
  • ANSI/RIA R15.06 (2012) - Safety Requirements for Industrial Robots
  • ANSI B11.0 (2010) - Safety of Machinery – General Requirements and Risk Assessment
  • ANSI B11.19 (2010) - Performance Standard for Safeguarding
  • ANSI B55.1 (2012) - Packaging Machinery
  • ANSI 12100 (2012) - Safety of Machinery - Basic Concepts, General Principles for Design - Risk Assessment and Risk Reduction
  • ANSI/ASSE Z244.1 (2003) – Control of Hazardous Energy – Lockout/Tagout and Alternative Methods
