Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces GB/T 17436-1998 "Selection of explosion-proof electrical equipment in hazardous areas of ships" and is consistent with GB/T 17436-1998.
In addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) Added the classification of explosion-proof electrical equipment types (see 4.1.1.1);
b) Added the principle of three-zone division of ship dangerous areas (see 4.2.3);
c) Added positive pressure ("p") electrical equipment (see 4.3.1, 10.2.2 and B.5 of Appendix B);
d) The selection requirements for explosion-proof electrical equipment based on the principle of three-zone division of dangerous areas of ships have been changed (see 4.4, 4.4 of the.1998 edition);
e) The selection requirements for explosion-proof electrical equipment of liquid cargo ships according to the principle of three-zone division of ship hazardous areas have been changed (see Chapter 6, Chapter 7,
Chapter 8, Chapter 9, Chapter 6, Chapter 7, Chapter 8, Chapter 9 of the.1998 edition).
