1.1 本规范规定了固态条形图型指示仪表的设计、结构、性能和测试要求。 1.2 本规范所涵盖的固态条形图仪表适用于船上电气测量应用。本规范涵盖固态、面板式（扁立）和矩形配电盘式仪表的要求和质量保证规定，这些仪表使用发光二极管（LED）进行条形图指示和可选数字显示器。 1.3 本规范的要求可用于专门的测量应用，其中另一个量，例如大气样品中微量元素的位置、重量、浓度等，被转换为电能用于显示和测量。这种情况下应指定特殊的刻度盘标记。 1.4 以国际单位制表示的数值应视为标准。 括号中给出的值是对英寸磅单位的数学转换，仅供参考，不被视为标准。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification provides the requirements for design, construction, performance, and testing of solid state bargraph-type indicating meters. 1.2 The solid state bargraph meters covered by this specification are intended for use in shipboard applications of electrical measurement. This specification covers the requirements and quality assurance provisions for solid state, panel-type (edgewise), and rectangular switchboard-type instruments, which use light-emitting diodes (LEDs) for bargraph indication and optional digital displays. 1.3 This specification’s requirements may be invoked for specialized measurement applications where another quantity, for example, position, weight, concentration of a trace element in an atmosphere sample, and so forth, is converted to electrical energy for display and measurement. Special dial markings shall be specified for such cases. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
