As in other material categories, the reliable use of plastics and composites requires specifications to support procurement of these materials and standards to establish engineering and technical requirements for processes, procedures, practices, and methods for testing and using these materials. These specifications and standards may be general industrywide, or they may be specific to one industry, such as the spaceborne industry, wherein plastics and composites must exhibit special stability in the harsh environments of temperature and vacuum. Specifications and standards for this industry, for instance, would be controlled by documents from the National Aeronautics and Space Administration (NASA). Increasingly, the development and use of standards is becoming international. Since the total sum of these specifications and standards is voluminous, no attempt is made herein to itemize all of them. However, the names and addresses of organizations that are sources of these documents, and information concerning them, are listed below. Also, one comprehensive reference book that can be recommended to readers with interest in this area is given as Ref. 1 at the end of this listing. Another excellent reference book dealing with the major issues of flammability standards of plastics and composites is listed as Ref. 2.
