ASTM D3438-07
(Practice)Standard Practice for Sampling and Handling Naphthalene, Maleic Anhydride, and Phthalic Anhydride
Standard Practice for Sampling and Handling Naphthalene, Maleic Anhydride, and Phthalic Anhydride
SCOPE
1.1 This practice covers procedures for sampling and handling naphthalene, maleic anhydride, and phthalic anhydride in various solid forms, and as liquids at elevated temperatures in a safe manner that represents and preserves quality.
1.2 Any person sampling or handling these products should consult the applicable Material Safety Data Sheets (MSDS) for specific first aid instructions and information on the proper equipment to have available for use in the event of personal contact or exposure.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 3, 4, 5, 6, and 7.
