前言:这是CSA C863《高强度放电（HID）和低压钠灯（LPS）镇流器的能效》的第三版。它取代了2011年和2004年出版的前两个版本。本标准涵盖了HID和LPS灯镇流器的试验程序、最低能量性能要求和标记要求。本标准旨在为特定类型的灯镇流器提供能效测试方法和最低效率水平。本标准不是对任何特定类型灯具或灯具的认可。 人们认识到，一个完整照明系统的整体效率和效能取决于许多超出本标准范围的因素。CSA集团感谢加拿大自然资源部（NRCan）的财政支持，使本标准的制定成为可能。范围:1.1本标准适用于所有高强度放电（HID）和低压钠灯（LPS）镇流器，其输入线频率为60 Hz。 注:CAN/CSA-C22第2部分提供了镇流器的安全要求。2 No.74.1.2本标准定义了用于确定HID和LPS灯具中使用的HID和LPS灯镇流器效率的测量技术。1.3本标准规定了HID和LPS灯镇流器的最低能效水平。注:功率因数也是能源管理的一个重要考虑因素，但不在本能效定义的范围内。1.4本标准不适用于受监管的- 滞后金属卤化物灯镇流器；b） 480V工作的电子金属卤化物灯镇流器；c） 高频电子金属卤化物灯镇流器，以1000 Hz或更高的输出频率操作灯；和d）特殊应用汞蒸气灯镇流器。注:本标准第3.1.5条定义了汞蒸气灯镇流器的特殊应用，“应”用于表示要求，即用户有义务满足的条款，以符合本标准； “应该”用于表示建议或建议但不需要的建议；“可”用于表示一个选项或在标准范围内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释的目的是将解释性或信息性材料与文本分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附件被指定为规范性（强制性）或信息性（非强制性）- 必须）定义其应用程序。1.6国际单位制给出的数值为本标准中的记录单位。括号中给出的值仅供参考和比较。

Preface:This is the third edition of CSA C863,Energy efficiency of high-intensity discharge (HID) and low-pressure sodium (LPS) lamp ballasts. It supersedes the previous editions published in 2011 and 2004.This Standard covers the test procedure, minimum energy performance requirements, and marking requirements for HID and LPS lamp ballasts.This Standard was developed to provide an energy efficiency test method and minimum efficiency levels for specific types of lamp ballasts. This Standard is not an endorsement for any particular type of lamp or luminaire. It is recognized that the overall efficiency and efficacy of a complete lighting system depends on a number of factors that are beyond the scope of this Standard.CSA Group gratefully acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan).Scope:1.1This Standard applies to all ballasts for high-intensity discharge (HID) and low-pressure sodium (LPS) lamps intended to operate with an input line frequency of 60 Hz.Note:Safety requirements for ballasts are provided in Part 2 of CAN/CSA-C22.2 No. 74.1.2This Standard defines the measurement technique for determining the efficiency of HID and LPS lamp ballasts for use in HID and LPS luminaires.1.3This Standard defines minimum energy efficiency levels for HID and LPS lamp ballasts.Note:Power factor is also an important energy management consideration, but is not within the scope of this energy efficiency definition.1.4This Standard does not apply toa) regulated-lag metal halide lamp ballasts;b) electronic metal halide lamp ballasts that operate at 480 V;c) high-frequency electronic metal halide lamp ballasts that operate a lamp at an output frequency of 1000 Hz or greater; andd) specialty application mercury vapour lamp ballasts.Note:Speciality applications mercury vapour lamp ballasts are defined in Clause 3.1.5In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.1.6The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
