IEC 60662:2011规定了符合IEC 62035安全要求的一般照明用高压钠灯的性能要求。这第二版取消并取代了1980年出版的第一版及其修正案。它构成技术修订。需要开发IEC 60662第2版的主要项目有: -对性能要求的限制。安全要求在IEC 62035:放电灯（不包括荧光灯）-安全规范中给出； -引入点火测试装置； -使用测试装置和不使用测试装置的灯数据表的拆分； -启动期间的测量、电气和光度特性的测量以及流明维护和寿命测试的规定； -一般审查，例如最大灯轮廓和数据对齐； -按瓦数排列的数据表新顺序。

IEC 60662:2011 specifies performance requirements for high-pressure sodium vapour lamps for general lighting purposes which comply with the safety requirements of IEC 62035. This second edition cancels and replaces the first edition published in 1980 and its amendments. It constitues a technical revision. Main items that required development of the 2nd edition of IEC 60662 are:
- restriction to performance requirements. Safety requirements are given in IEC 62035: Discharge lamps (excluding fluorescent lamps) - Safety specifications;
- introduction of a test device for ignition;
- split of the lamp data sheets which make use of the test device and those which do not;
- provisions for measurement during starting, measurement of electrical and photometrical characteristics and tests for lumen maintenance and life;
- general review e.g. of maximum lamp outlines and alignment of data;
- new order of data sheets by wattage.
