ASTM E3231-19 PDF

1.1 This guide outlines best practices to consider when setting up a representative leachable test method to detect if a material is compatible with cell culture media or manufacturing processes. This guide does not replace or supersede cell growth tests like USP <87>, USP <88> (plastic/elastomeric materials), or ISO 10993 (medical device materials), that are used in assessing biological reactivity in humans. Polymeric materials that have passed these tests have been found to leach compounds under normal process conditions that can inhibit cell culture growth for some cell lines. See Refs (1-5).2 Test methods that are representative of the manufacturing conditions will help identify materials that are appropriate for use during manufacturing.

1.2 This guide may be relevant to biopharmaceutical manufacturing, cell-based therapeutics, vaccines, cell-based diagnostics, and other areas.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
