Ninety years of terminology management in ASTM

The American Society for Testing and Materials has been engaged in management of terminology for more than nine decades across many subject disciplines. Throughout this period methods have been developed and applied to management of terminology. One technique, generating and maintaining an audited list of terms and definitions, has proved useful in promoting greater uniformity of term usage. Other methods of promoting improved definition writing and layout have also been developed and applied. These methods are described in their historical context. Problems of a multidisciplinary set of independent standards-writing committees are also discussed with proposed solutions.
