Revised proposal as adopted by the 109th GRSG session to revise the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders. This proposal has been integrated with the proposal to regulate the discharge direction of pressure relief devices on CNG containers adopted by the 108th session. This document will be submitted as a revision to WP.29/2015/90 at the November 2015 World Forum session.
