3 ASTM International Fast Facts Formed in 1898World-Wide Development of Voluntary, Full-Consensus Standards for Materials, Products, Systems & Services12,000 Standards Developed by 138 Technical Committees are Administered, Published, and Distributed by ASTM InternationalOver 32,500 Members from 125 Countries Participate on ASTM CommitteesASTM Standards are Living Documents, Continually Revised to Meet Stakeholder Needs, Reflecting Current TechnologyEach member – not a company or country – gets a vote
4 Committee D30 on Composite Materials Committee D30 formed in 1964 (with heritage to the early ‘50s) out of Committee D20 on PlasticsCurrent (2009) D30 Scope“The Committee will develop standard test methods, practices, terminology, and guides; sponsor symposia; stimulate research; and exchange technical information pertaining to composite materials (primarily those with fibrous reinforcement), as well as to reinforcing fibers with a Young's modulus greater than 20 GPa (3 Msi).This Committee will not develop standard specifications.”D30 ObjectiveA complete, effective, and coordinated suite of testing standards for composites

6 ASTM Technical Committee Organization Technical Committees form to address specific industry issues. They develop scopes to define their jurisdiction.MAIN COMMITTEESubcommittees are established to address subsets of specialized subject matter under the scope of the Main Committee.Subcommittee.01Subcommittee.02Subcommittee.03Subcommittees further organize their expertise into small Task Groups. This is the level at which documents are first developed and are subsequently revised.Task Group1Task Group2The 138 Technical Committees, 2,000+ Subcommittees, & thousands more Task Groups produce 1,200 drafts, or revisions to drafts, annually.

8 ASTM International Balloting Process COMMITTEE ON STANDARDS (COS) 4) As a final check, a standing committee (COS) of the ASTM Board of Directors reviews the process by which each standard is developed or revised, to ensure compliance with ASTM regulations.COMMITTEE ON STANDARDS (COS)3) After S/C approval the Main Committee votes. If approved it is presented to the Committee on Standards for final review. Otherwise it returns to the Task Group for re-work & balloting is repeated.MAIN COMMITTEE2) A completed draft is voted on by the Subcommittee. If approved, it moves to a Main Committee vote. If not, it returns to the Task Group for re-drafting.SUBCOMMITTEETASKGROUP1) Starting Point. Documents are drafted, and continually revised, in the Task Group by a few members who specialize in the subject matter. This is where the bulk of the activity occurs.
