本文件规定了1974年《国际海上人命安全公约》第五章第19条第2.9.1款规定的转向率指示器的结构、性能要求、测试方法和要求的测试结果（2000年修订）。 它基于IMO决议A.526（13）的要求，也与IMO决议A.694（17）和IEC？60945有关。 如果本文件中的要求与IEC？60945中的要求不同，则以本文件中的要求为准。 注:从国际海事组织关于转向率指示器性能标准的决议A.526（13）的建议中提取的所有要求均以斜体印刷，决议和段落号用括号表示。

This document specifies the construction, performance requirements, methods of testing and required test results for the rate of turn indicators required by Clause？2.9.1, Regulation 19, chapter V, SOLAS？1974 (as amended, 2000). It is based upon the requirements of IMO Resolution A.526(13), and is also associated with IMO Resolution A.694 (17) and IEC？60945. Where a requirement in this document is different from that in IEC？60945, the requirement in this document takes precedence. NOTE？All requirements that are extracted from the recommendations of IMO Resolution A.526(13) on performance standards for rate of turn indicators are printed in italics and the resolution and paragraph numbers are indicated in brackets.
