Commonly Cited Standards



AASHTO (American Association of State Highway & Transportation Officials)
The American Association of State Highway & Transportation Officials (AASHTO) is a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia and Puerto Rico. It is the only national public sector association that represents all five transportation modes: air, highways, public transportation, rail and water. Its primary goal is to foster the development, operation and maintenance of an integrated national transportation system.

Some of the major AASHTO publications which include standards are:

ACI (American Concrete Institute)
The American Concrete Institute (ACI) serves the various components of the concrete industry. It has about one hundred technical committees, and the documents produced by these committees are arranged into five groups in the six-part Manual of Concrete Practice (MCP) (Engineering Library Reference, TA681.A64)  which includes almost all of the Institute's codes, standards, and committee reports including 318-08: Building Code Requirements for Structural Concrete and Commentary. They include research and administration, materials and properties of concrete, design and construction practices, structural analysis, and special products and processes.

AHRI (Air-Conditioning, Heating, & Refrigeration Institute)
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is a voluntary, nonprofit organization comprised of the manufacturers of air conditioning, refrigeration, and heating products. The more than 60 standards now published are mainly performance-rating standards, although some are application or terminology standards. Many AHRI standards are accepted as American National Standards.

ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers)
ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers is an international organization of 50,000 persons with chapters throughout the world. The Society is involved with research, standards writing, continuing education and publications.

ASHRAE now offers free read-only access to some of their standards. Find what is available for free (These standards are read-only and can not be downloaded.)

Search for "ASHRAE handbook" in the UW Libraries Search to see the various ASHRAE manuals held in the UW Libraries.

ANSI (American National Standards Institute)  is the national coordinator of voluntary standards activities in the U.S. ANSI approves and publishes standards after they are developed by various engineering, industry and professional groups. ANSI is the U.S. representative to the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). ANSI does not produce standards.

ANSI Incorporated by Reference (IBR) Portal
The American National Standards Institute (ANSI) Incorporated by Reference (IBR) Portal provides a one-stop mechanism for access to standards that have been incorporated by reference in the U.S. Code of Federal Regulations (CFR). These standards incorporated by the U.S. government in rulemakings are offered at no cost in “read only” format and are presented for online reading. There are no print or download options.

ASME (American Society of Mechanical Engineers)  produces standards related to piping, fittings, cranes, elevators, screw threads, and other areas of interest to ASME. The ASME Boiler and Pressure Vessel Code is a well known publication. This code is comprised of 11 volumes and is located in the Engineering Library Standards area on the 1st floor at call number: TJ290 .A514.

ASTM  was originally known as the American Society for Testing and Materials. ASTM International is one of the largest voluntary standards development organizations in the world. ASTM develops technical standards for materials, products, systems, and services. ASTM Standards have an important role in the information infrastructure that guides design, manufacturing and trade in the global economy.

The UW Libraries has access to these standards online: ASTM Compass Digital Library. (UW Restricted).

The UW Libraries also has historical editions of the Annual Book of ASTM Standards in print.

The publication date is indicated by the last two digits in the standard number. For example: ASTM D2426-06 was last revised in 2006. 

AWS (American Welding Society)
The American Welding Society (AWS) works to advance the science, technology, and application of welding and related joining disciplines. AWS has published more than 140 standards under the guidelines of the American National Standards Institute. Search AWS in the UW Engineering Library Standards Database to see what welding standards the Library holds.

DISA (Data Interchange Standards Association)
DISA serves as the Secretariat for ASC X12 and their X12 EDI and XML standards development process.

ETSI (European Telecommunications Standards Institute)
European Telecommunications Standards Institute provides a searchable catalog on their webpage.

IEEE Standards are developed by the IEEE Standards Association. The UW Libraries provide access to these standards in full-text online at the IEEE Xplore Digital Library (Draft Standards are not included in access). (UW Restricted). 

Included also are the Interpretations of IEEE Standards, which provide answers to questions that may arise related to the meaning of portions of an IEEE standard concerning specific applications. Interpretations explain and clarify the intent of the standard; they do not constitute an alteration to the original standard or supply consulting information.

ASSIST: the Department of Defense Military Specifications, Standards and Related Publications
ASSIST is the official source for specifications and standards used by the Department of Defense (MIL-STDs & MIL-SPECs).

NACE (National Association of Corrosion Engineers)
Develops and disseminates surface preparation standards and other standards relevant to the Corrosion Industry.

NEMA (National Electrical Manufacturers Association)
The National Electrical Manufacturers Association is the trade association through which the electrical industry develops and promotes positions on standards and government regulations.

NFPA (National Fire Protection Association)
The NFPA advocates scientifically-based consensus codes and standards, research, and education for fire and related safety issues. NFPA offers free read-only access to their codes and standards. They do require you to create a free account in order to view the documents. (These standards are read-only and can not be downloaded.)
