GB/T 17556-2010Sheathing materials for shipboard power and telecommunication cables (English PDF)

Foreword

This standard is identical with IEC 60092-359:1999 "marine electrical equipment Part 359. Shipboard power and communication cable sheathing material material". (English Version) this standard is equivalent translation IEC 60092-359:1999, for ease of use, this standard the following editorial changes.

"." A) with a decimal point instead of IEC 60092-359:1999 as a decimal point, "";

b) Remove the IEC 60092-359:1999 Introduction and Foreword;

c) The IEC standard referenced in the foreword of this standard into the second chapter. For IEC 60092-359:1999 international standard reference , There is adopted as the equivalent of the standard by reference in this part of the standard instead of the international standard, the rest is not identical with me State standards are directly referenced in the standard;

d) To illustrate the references, the latest version of the standard undated, footnote "1)", "2)", "3)" will be explained, the original IEC footnote number "1)" to "4)";

e) according to IEC 60092-351. allow the normal operation of the 2004 cable conductor maximum temperature of Table 1 temperature value added to footnote "*", "**" Will be described.

This standard replaces GB/T 17556-1998 "shipboard power and telecommunication cable sheathing materials." this standard and GB/T 17556-1998, compared the main technical changes are as follows.

a) mechanical properties. SHF1, minimum elongation at fracture rate SHF2 before aging 125% to 120%.

b) Special Features.

--- Increasing the low-temperature performance test winding test, tensile test and impact test equipment, or in the case of the sample has been pre-cooled, Cooling time requirements;

--- Modified SHF1, SHF2 smoke transmittance requirements;

--- Increasing the ozone resistance test requirements.

c) adds an appendix.

Appendix A of this standard is an informative annex.

The standard proposed by China Shipbuilding Industry Corporation.

This standard by the National Standardization Technical Committee Marine Boats (SAC/TC12) centralized.

This standard was drafted. China Shipbuilding Industry Corporation seventh THOUSAND AND FORTY Institute, Shanghai Shenghua Cable Group, Changzhou 8 benefit cable Limited the company.

1 Scope

This standard specifies the test requirements of mechanical properties and special properties of shipboard power and telecommunication cables sheathing materials.
