Standards for end-users are plentiful as well, such as those detailing the standard practice for sizing fire and other thermal rescue service uniforms; the proper wearing, care, and maintenance of chemical protective clothing; or the selection, use, and care of high-visibility safety apparel.
Involved in the publishing of standards for protective clothing are standards developing organizations (SDOs) from around the world. ISO, the International Organization for Standardization, has published a large amount of standards regarding the testing, specifications of, and requirements for protective clothing, as have the national standards bodies (NSBs) of many countries, such as Germany, the United Kingdom, Japan, China, Austria, Sweden, Australia, and so forth. Furthermore, additional protective clothing standards have been developed by international SDOs, such as the International Safety Equipment Association (ISEA), the National Fire Protection Association (NFPA), and ASTM International, originally founded as the American Society for Testing and Materials. Additionally, the United States Department of Defense has also published several military specifications on the subject. Essentially, protective clothing is an area where proper standardization is seen to be vitally important by everybody involved.
