The American Society of Mechanical Engineers (ASME) defines a standard as:
"A standard can be defined as a set of technical definitions and guidelines, “how to” instructions for designers, manufacturers, and users. Standards promote safety, reliability, productivity, and efficiency in almost every industry that relies on engineering components or equipment. Standards can run from a few paragraphs to hundreds of pages, and are written by experts with knowledge and expertise in a particular field who sit on many committees."
Some print standards are also available in the library. To check if the library has a copy of a print standard, try searching in the Library Catalog.
