ASTM WK32995

    Revision of D635 - 10 Standard Test Method for Rate of Burning and/or Extent and Time of Burning of Plastics in a Horizontal Position

    (What is a Work Item?)

    Active Standard: D635 - 14

    Developed by Subcommittee: D20.30 | Committee D20 | Contact Staff Manager


    1. Rationale

    Project X30-323: ASTM D635 is horizontal burn test method. There is currently wording in Section 7 that reflects requirements associated with recognition or classification per flame performance. Since this document is designed to describe a test method, not criteria for recognition, those elements associated with classification and recognition are not relevant. It is proposed that the wording be removed from the body of the standard.
