  ABBREVIATIONS:

  L1 Fire endurance test (appendix 1) in dry conditions, 60 minutes

  L2 Fire endurance test (appendix 1) in dry conditions 30 minutes

  L3 Fire endurance test (appendix 2) in wet conditions, 30 minutes

  0 No fire endurance test required

  NA Not applicable

  X Metallic materials having a melting point greater than 925°C

  FOOTNOTES:

  1/ Where non-metallic piping is used, remotely controlled valves to be provided at ship's side (valve is to be controlled from outside space).

  2/ Remote closing valves to be provided at the cargo tanks.

  3/ When cargo tanks contain flammable liquids with f.p. > 60°C, “0” may replace “NA” or “X”.

  4/ For drains serving only the space concerned, “0” may replace “L1”.

  5/ When controlling functions are not required by statutory requirements of guidelines, “0” may replace “L1”.

  6/ For pipe between machinery spaces and deck water seal, “0” may replace “L1”.

  7/ For passenger vessels, “X” is to replace “L1”.

  8/ Scuppers serving open decks in positions 1 and 2, as defined in Regulation 13 of the International Convention on Load Lines, 1966, should be “X” throughout unless fitted at the upper end with the means of closing capable of being operated from a position above the freeboard deck in order to prevent downflooding.

  9/ For essential services , such as fuel oil tank heating and ship's whistle, “X” is to replace “0”.

  10/ For tankers where compliance with paragraph 3.6 of regulation 19 of annex I of MARPOL 73/78 is required, “NA” is to replace “0”.
