Proposal to insert a new chapter P and paragraphs 247 and 248 establishing that supply lines for additional TPRDs are constructed from metallic materials with further investigation required for other materials in the next phase, and requiring manufacturers to provide handling procedures to ensure supply lines will not suffer damage or contamination during handling with removal from service of lines with unacceptable damage, exclude the drop test from the requirements at para. 51., and amend para. 81. (c) (i) to clarify that drop impact testing applies to containers without supply lines and valves with damage to supply lines or valves requiring replacement.
