Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

This document replaces GB/T 4541-2008 "Self-illuminating floating lights for lifebuoys" and GB/T 30488-2014 "Lights for survival craft and rescue boats" and is consistent with Compared with GB/T 4541-2008, in addition to structural adjustments and editorial changes, the main technical changes are as follows:

a) Incorporated the technical content of GB/T 30488-2014 "Survival Crafts and Rescue Boat Lights";

b) Added terms and definitions (see Chapter 3);

c) Delete the size and weight requirements for self-illuminating buoy lights of lifebuoys (see 3.1.3 of the 2008 edition);

d) Changed the energy source and lighting type used by the position indicator lights (see 4.1.2, 2.1 of the 2008 edition);

e) Delete the requirements for water spray conditions in deluge and watertightness (see 4.5 of the 2008 edition);

f) The spectral energy distribution requirement is deleted (see 4.14 of the 2008 version);

g) Added the requirements for immersion in fresh water for the high and low temperature cycle performance of the lifebuoy self-illuminating floating light (see 5.3.1 and 5.3.2);

h) Add requirements for water-activated battery position indicators (see 5.3.4);

i) Added requirements for the arrangement of light switches on boats that are activated by pulling the light body when the life raft expands (see 5.12.2);

j) Add requirements for positioning devices (see 5.13);

k) The number of high and low temperature cycle tests for the self-illuminating floating light of the lifebuoy has been increased, as well as the test method for immersion in fresh water (see 6.2.3);

l) The formula for luminous intensity has been changed (see 6.3.2.2, 4.4 of the 2008 edition);

m) The factory inspection requirements for the appearance of ring lights have been changed (see 7.3.1, 5.3.2 of the 2008 edition).
