GB/T 29485-2025Ships and marine technology - Electric rudder angle indicators (English PDF)

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".

This document supersedes GB/T 29485-2013 "Electrical Rudder Angle Indicators for Ships and Marine Technology" and is consistent with GB/T 29485-2013.

Compared to previous versions, aside from structural adjustments and editorial changes, the main technical changes are as follows.

a) Added specifications for displays (see 4.1);

b) Added provisions for alarms (see 4.4);

c) Added requirements for displays used for information display (see 6.1);

d) Added alarm testing requirements (see 6.6);

e) The requirements for the interface have been changed (see Chapter 7, Chapter 7 of the 2013 edition).

This document is equivalent to ISO 20673:2022 "Electrical rudder angle indicators for marine and marine technologies".

1 Scope
