Abstract

Standards are an important component of national and international trade. We depend upon standards to assure that manufactured parts will work together, wherever they are made, and that we speak the same technical language, no matter what language we speak. Understanding is important in order to know when to take exceptions to or tailor the standard to fit the job. Standards that are used in contamination control have increased in numbers over the years as more industries have had to improve their manufacturing processes to enhance reliability or yields of products. Some older standards have been revised to include new technologies, and many new standards have been developed. Some of the new standards were written for specific industries while others apply to many industries. Many government standards have been replaced with standards from nongovernmental standards organizations. This trend has been encouraged by U.S. law that requires the government to use commercial standards where possible. This paper reviews some of the more important standards for the aerospace industry, such as IEST-STD-CC1246 and ISO 14644-1, that have been published in recent years. Benefits, usage, and problems with some standards will be discussed. Some standards are referenced, and websites of some standards organizations are listed.
