ASTM WK87305

Revision of D7826-23a Standard Guide for Evaluation of New Aviation Gasolines and New Aviation Gasoline Additives

Rationale

This ballot is for the proposed addition of Buna-N Top Coat integral fuel tank sealant, also referred to as “Slosh Coat”. This sealant is PPG PR-1005-L; SAE-AMS-3284, Type 2, Class B-2, which is applied as a liquid to the internal fuel tanks, as opposed to the paste-like sealants already in the document. References for the material, the exposure tests, and the durations are proposed for addition. With the addition of this sealant, it becomes necessary to further delineate the non-metallic test descriptions which are exceptions from the original ubiquitous 28-day exposure testing performed on non-metallic materials.
