According to the ASTM Regulations Governing Technical Committee Operations, on classified committees and subcommittees, members shall be classified according to voting interest. The classification of a member at the main committee may be different from the classification at the subcommittee level; however, a member classified on any subcommittee as a producer shall be classified as a producer on the main committee.   Classifications include Producer, User, Consumer, and General Interest. For more information on classification, refer to the ASTM Regulations and your Committee Bylaws.
