Technical standards are usually formal documents that specifies uniform design, manufacturing processes, performance and maintenance criteria and practices for a material, product, or method. Standards ensure quality, safety, and interoperability of systems and parts. Standards are usually issued by scientific, professional, or trade organizations or by governments.
Codes are standards for methods and materials used in buildings, processes, and products that governments have made mandatory in order to protect public safety.
A standard is usually cited by the acronym of the organization that issued it, followed by a number, and then the date it was issued. For example IEEE Std. 15.7-2018 is a standard for short-range wireless optical communication using visible light issued by IEEE in 2018.
Search the following databases to identify standards. You will not be able to read the full text of standards in these databases. Many standards can be purchased as a pdf available to only a single user. The library may be able to provide limited access to some standards, depending on licensing and price restrictions- contact the library if you need a specific standard.
The U.S. government's Code of Federal Regulations (CFR) refers to many standards that must be followed by law. These standards are called standards incorporated by reference (IBR), and they are available for free online in "read only" format (they can not be printed or downloaded). "All users will be required to install the FileOpen plug-in and accept an online end user license agreement prior to accessing any standards."
The ANSI website hosts many IBR standards and links to the standards developing organizations websites for the rest at: https://ibr.ansi.org/Standards/Default.aspx#hosted-ansi
