  2. What Is ASTM? • American Society for Testing & Materials • A non-commercial organization • Founded in 1898 • Headquartered in Pennsylvania • Coordinates >10,000 written standards • Involves 132 standards-writing committees • Has 32,000 volunteer members worldwide • Dedicated to promoting testing excellence - 2 -

  3. Who Are ASTM's Members? • Producers • Companies who make a product • Users • Companies who use a product • General interest • Academics, government laboratories and other interested individuals - 3 -

  4. ASTM Standard Test Methods • What is an ASTM standard? • Developed by a technical committee • Composed of detailed instructions • Evaluated by multiple users • Approved by a consensus of ASTM members • Who develops ASTM standards? • Anyone can suggest the need for a method • A technical committee considers options • Methods are developed by concensus - 4 -

  5. Why Are ASTM Standards Needed? • ASTM standards provide • Robust methods for general use • A common ground to discuss materials manufacturing specifications • Impartial methods to resolve disputes • A tested introduction to a subject or characterization methodology - 5 -

  6. What Do ASTM Standards Deal With? • ASTM standards include: • Chemical analysis techniques • Physical property methods • Sampling protocols • Catalyst utilization methods • Instrumental methods • Technical definitions • Editorial guidance - 6 -

  7. What Is the ASTM D-32 Committee on Catalysts? • The D-32 Committee • Was established January, 1975 • Resulted from an AICHE meeting on catalytic standards • Has published more than 41 standards • Consists of more than 41 volunteers - 7 -

  8. Who Are Members of D-32? • Our members span the global catalyst and materials producer/user communities • Chemical companies • Refining companies • Catalyst suppliers • Carrier suppliers • Equipment vendors • Technology licensors • Academic researchers • Government laboratory scientists - 8 -

  9. All D-32 Test Methods Contain Several Key Elements • Safety considerations • Sampling plan • Required sample pretreatment • Required reagent quality • Inter-lab round-robin testing protocol • Data reduction information • Statistical evaluation/validation - 9 -

  10. How Does D-32 Function? • Members meet for two days, twice a year • Sites rotate within North America • Eleven subcommittees meet as needed • Task groups coordinate efforts • Members develop draft test method(s) • Formulate testing plans and conduct tests • Evaluate results • Submit test method(s) for Society approval - 10 -

  11. The D-32 Committee’s Mission/Scope • Our Committee's Scope: • The development of test methods, classifications, practices and terminology pertaining to catalysts, zeolites and related materials used in their manufacture, and the stimulation of research related thereto. The work of this Committee will be coordinated with other ASTM committees and other organizations having mutual interests. - 11 -
