ANSI MSS SP-96-2017 pdf free download – Terminology for Valves, Fittings, and Their Related Components.
1.1 This Standard Practice lists and defines principle terms, acronyms, and abbreviations that are widely used to describe valves, fittings, and their related components. It is comprised of separate sections which contain:
Acronyms for organizations whose documents are applicable to valves, fittings, and their related components, and a brief summary of the applicable area of interest as it relates to this subject.
A glossary of terms used within the valve and fittings industry, including standards developers,to describe design, operation, and performance characteristics.
Abbreviations commonly used in the valve and fittings industry.
2. DOCUMENT SOURCES AND ACRONYMS
A number of technical societies, Standards Development Organizations (SDOs), trade associations, and governmental agencies promulgate codes, standards, or specifications that are pertinent to the valve and fittings industry. Many SDOs are recognized throughout the valve and fittings industry, while others are relevant to specific services, segments, or regions, while others are applicable to all usages within a specific industry. The organizations and their acronyms most frequently referenced, and their relationship to the valve and fittings industry, are listed below in alphabetical order (according to acronym):
AAR Association of American Railroads – publishes design and dimensional standards for bronze valves and 300 psi pressure rating, malleable pipe fittings used by railroads.
ABS American Bureau of Shipping – publishes safety standards for shipbuilding, including specifications for valves and fittings used in commercial maritime service.
ACI Alloy Castings Institute – publishes material specifications for heat and corrosion resistant alloys.
AESC American Engineering Standards Committee – one of the precursor structures of ANSI;from 1916 to 1928.
AFS American Foundry Society – publishes information on casting methods, procedures, and practices that are basic references for product design, procurement, and inspection of cast products.
AGA American Gas Association – a trade association that represents companies which deliver natural gas to customers. Promotes and advocates for natural gas industry issues, regulatory constructs and business models that are priorities for their industry. See “CSA” with regard to gas distribution markings.
AISI American Iron and Steel Institute – a trade association that represents the North American steel industry; membership comprised of furnace steelmakers and suppliers to or customers of the steel industry.
ANSI American National Standards Institute – serves as administrator of the United States voluntary standardization system by accrediting the procedures of standards developing organizations (SDO’s); known as ASDs or Accredited Standards Developers. ANSI originally organized in 1916 as the American Engineering Standards Committee (AESC).
In 1928, it was reorganized and renamed the American Standards Association (ASA), then reorganized in 1966 as the United States of America Standards Institute (USASI), and finally adopted its current name in 1969. Note that ANSI is also the sole U.S. member body to the ISO and IEC.
API American Petroleum Institute – a trade association and SDO that publishes standards for systems and equipment related to the oil and natural gas industry.
ASA American Standards Association – one of the precursor structures of ANSI (1928 to 1966).
ASHRAE American Society of Heating, Refrigerating and Air-Conditioning Engineers – a trade association and SDO that publishes standards for systems and equipment related to the built environment; formally known as American Society of Heating and Ventilating Engineers (ASHVE).ANSI MSS SP-96 pdf download.
