This section GB/T 4798 Part 6.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 4798.6-1996 "Electrical and electronic products for marine applications environmental conditions", and GB/T 4798.6-1996 phase Ratio, the main changes are as follows.

--- Increasing environmental parameters in Table 1 rating 6K6,6K7;

--- In Appendix A A.2 increased climate conditions 6K6,6K7 instructions;

--- Added Appendix B (informative);

--- Added Appendix NA (informative).

This section uses the translation method identical with IEC 60721-3-6. 1987 "Classification of environmental conditions - Part 3. classification of groups of environmental parameters and their Severities - Section 6. Ship "and their single amendment No. 1 (1991-06) and Amended Order (1996-11), and made the following editorial Modifications.

--- "This part of IEC 60721-3-6," modify "GB/T 4798.6 of this part";

--- "Technical Report" to "this Part";

--- Remove the IEC 60721-3-6 foreword and introduction, foreword increase the national standards;

--- According to GB/T 1.1-2009 requirements, increased Chapter 3, "normative references", then reg numbers sequentially adjusted;

--- Added Appendix NA (informative).

1 Scope

GB/T 4798 in this part is to classify groups of environmental parameters and their severities products installed on the ship endured made grading.

These products can be long-term or temporarily mounted on the following ships.

--- The mechanical propulsion of the ship, including a mobile offshore platforms.

--- Non-mechanical means of propulsion of ships, including sailing and life raft.

The provisions rating applies to ships from the yacht to trawlers, ferries, icebreakers, cargo ships (including tankers), and other various scales.

Normal ship sailing region.

--- Inland waterways (canals, rivers, lakes);

--- Coastal waters;

--- Ocean.

Ships must also include ice sailing.

This part of groups of environmental parameters classification and grading severities apply to products for the operation, management and security installed on the ship, but also Other products can be used in a similar manner is mounted on the same site.

This section does not include incidental accidents, but safe operation of the ship have a major impact products should consider the possibility of an accident.

This classification does not include the effects of pressure on the underwater products.

Classification of groups of environmental parameters and their severities classification, see the application by a mechanical means of propulsion in ships IEC 60092-101 Requirements in relation to environmental conditions.

Storage and transportation environmental conditions classification by the IEC 60721-3 regulations.

Objective 2

This aim is part of the product is installed on board, under its conditions of use will be subjected to all kinds of groups of environmental parameters and their severities classified into Hierarchical.

This section groups of environmental parameters and their severities classified into a limited number of grades, but its field of application is very broad. When using this section, should be selected to cover the expected conditions of use required minimum level.
