12、 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cl

19、 construction, performance requirements, methods of testing, and required test results for electric and electronic propeller shaft revolution indicators (hereinafter referred to as “indicator system”) required by Clause 2.5.4, Regulation 19, chapter V, SOLAS 1974 (as amended, 2000).This Internationa
20、l Standard is associated with IMO Resolution A.694 (17) and IEC 60945.Where a requirement in this International Standard differs from IEC 60945, the requirement in this International Standard takes precedence.NOTE When this indicator system can be used as the tachometer for the engine of a ship, its
21、 usage as the tachometer will be accepted.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
