Rationale

1. Propose a change in the solids contents to be even more representative of the dry tomb landfills. To remove lower solids contents (35% and 45%) and to include 75% solid content instead. This revision would streamline the test by focusing on two representative solids content levels 60% and 75% which align more closely with actual dry tomb landfill conditions and also improves efficiency of the test by minimizing the number of required test reactors. In addition, we could propose a title revisions as well. 2. Propose to change the title of the standard. Current Title (Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under Accelerated Landfill Conditions) . Proposed change ( Standard Test Method for Determining Anaerobic Biodegradation of Thermoplastics, Elastomers and Biopolymers under Dry tomb landfill conditions.) As the current title is limited plastics, replacing it to additional polymer materials will give a broad scope of materials to test using this standard.
