Rationale

With continued use of ASTM D7826, users and manufacturers continue to modify the materials to be tested. The latest reviews have identified a need to include two non-metallic materials to Table A2.2 Nonmetallics; “Delrin” acetal resin, and Tygon F 4040-A tubing, and to clarify the requirement in A5.7.3.2 to use Sovay BR 127 corrosion inhibiting primer in the preparation of test panels for Hysol EA9628 structural metal bonding adhesive.
