In addition to facilitating the formation of standards in the United States, ANSI promotes the use of U.S. standards internationally, advocates U.S. policy and technical positions in international and regional standards organizations, and encourages the adoption of international standards as national standards where appropriate. The institute is the official U.S. representative to the two major international standards organizations, the
International Organization for Standardization (ISO), as a founding member, and the
International Electrotechnical Commission (IEC), via the U.S. National Committee (USNC). ANSI participates in almost the entire technical program of both the ISO and the IEC, and administers many key committees and subgroups. In many instances, U.S. standards are taken forward to ISO and IEC, through ANSI or the USNC, where they are adopted in whole or in part as international standards. Adoption of ISO and IEC standards as American standards increased from 0.2% in 1986 to 15.5% in May 2012.
Standards panels The Institute administers nine standards panels: • ANSI Homeland Defense and Security Standardization Collaborative (HDSSC) •
ANSI Nanotechnology Standards Panel (ANSI-NSP) • ID Theft Prevention and ID Management Standards Panel (IDSP) • ANSI Energy Efficiency Standardization Coordination Collaborative (EESCC) • Nuclear Energy Standards Coordination Collaborative (NESCC) • Electric Vehicles Standards Panel (EVSP) • ANSI-NAM Network on Chemical Regulation • ANSI Biofuels Standards Coordination Panel • Healthcare Information Technology Standards Panel (HITSP) Each of the panels works to identify, coordinate, and harmonize voluntary standards relevant to these areas. In 2009, ANSI and the
National Institute of Standards and Technology (NIST) formed the Nuclear Energy Standards Coordination Collaborative (NESCC). NESCC is a joint initiative to identify and respond to the current need for standards in the nuclear industry.
American national standards • The
ASA (as for American Standards Association) photographic exposure system, originally defined in ASA Z38.2.1 (since 1943) and ASA PH2.5 (since 1954), together with the
DIN system (DIN 4512 since 1934), became the basis for the
ISO system (since 1974), currently used worldwide (
ISO 6,
ISO 2240,
ISO 5800,
ISO 12232). • In
Microsoft Windows, the phrase "ANSI" refers to the
Windows ANSI code pages (even though they are not ANSI standards). Most of these are fixed width, though some characters for
ideographic languages are variable width. Since these characters are based on a draft of the
ISO-8859 series, some of Microsoft's symbols are visually very similar to the ISO symbols, leading many to falsely assume that they are identical. • The first computer
programming language standard was "American Standard
Fortran" (informally known as "FORTRAN 66"), approved in March 1966 and published as ASA X3.9-1966. • The programming language
COBOL had ANSI standards in 1968, 1974, and 1985. The COBOL 2002 standard was issued by
ISO. • The original standard implementation of the
C programming language was standardized as ANSI X3.159-1989, becoming the well-known
ANSI C. • The
X3J13 committee was created in 1986 to formalize the ongoing consolidation of
Common Lisp, culminating in 1994 with the publication of ANSI's first object-oriented programming standard. • A popular
Unified Thread Standard for nuts and bolts is ANSI/ASME B1.1 which was defined in 1935, 1949, 1989, and 2003. • The ANSI-NSF International standards used for commercial kitchens, such as restaurants, cafeterias, delis, etc. • The ANSI/APSP (Association of Pool & Spa Professionals) standards used for pools, spas, hot tubs, barriers, and suction entrapment avoidance. • The ANSI/HI (Hydraulic Institute) standards used for pumps. • The ANSI for
eye protection is Z87.1, which gives a specific impact resistance rating to the eyewear. This standard is commonly used for shop glasses, shooting glasses, and many other examples of protective eyewear. While compliance to this standard is required by United States federal law, it is not made freely available by ANSI, who charges $65 to read a
PDF of it. • The
ANSI paper sizes (ANSI/ASME Y14.1). ==See also==
