1 Scope

This standard specifies the marine electric measuring and control instruments (hereinafter referred to as marine electric meter) requirements, test methods, inspection rules,

Logo and packaging requirements.

This standard applies to all kinds of ships and marine engineering using an electric measuring and control instruments.

This standard applies to the marine electric meter can be divided according to their functions.

a) instrumentation (detected temperature, pressure, level, flow, mechanical variables such as the amount of used instruments);

b) control instrument (position controller, continuous controller, etc.);

c) actuators (control valves, actuators, etc.);

d) display instruments (recorder, indicator, etc.);

e) other suitable instrument.

For different types of product specific technical requirements were not specified in this standard shall comply with the respective product standards or technical conditions.
