范围1.1概述本标准涵盖了用于测量电池充电器能量消耗的测试要求，电池充电器拟在115 V ac、60 Hz线路电压下通过插头连接到墙壁插座或现有直流电源（如汽车电源插座或USB端口）运行。本范围包括使用ANSI/NEMA WD 6-2016中规定的标准化美国电气制造商协会（NEMA）插头1-15P或5-15P且具有交流输出的不间断电源。1.2目的本标准中规定的试验方法旨在补充CSA C381.1中包含的方法。本标准和CSA C381.1定义了两类用于能源性能测试的产品；CSA C381.1范围内的产品不适用于本标准的测试。附录B规定了确定测量产品的适当试验方法（CSA C381.1或本标准）的要求？s的能源性能。 1.3除外条款本标准不包括以下内容:a）《加拿大医疗器械条例》第1节中定义的“医疗器械”；b） 备用电池充电器；直流输出不间断电源（UPS）。1.4本标准中的术语“应”用于表示要求，即用户有义务满足的规定，以符合本标准；“宜”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限制内允许的选项。注释随附条款不包括要求或替代要求；随附条款的注释旨在与文本中的解释性或信息性材料分开。表和图的注释被视为表或图的一部分，可以作为要求编写。附录被指定为规范性（强制性）或信息性（非强制性）以定义其应用。

Scope1.1 GeneralThis Standard covers the test requirements used to measure battery charger energy consumption for battery chargers intended to be operated from 115 V ac, 60 Hz line voltage connected by plug to wall receptacles or existing dc sources (such as automotive power jacks or USB ports). Uninterruptible power supplies that utilize the standardized National Electrical Manufacturer Association (NEMA) plug, 1-15P or 5-15P, as specified in ANSI/NEMA WD 6-2016 and have an ac output are included in the scope.1.2 PurposeThe test method specified in this Standard is intended to complement the methodology contained in CSA C381.1. This Standard and CSA C381.1 define two classifications of products for the purpose of energy-performance testing; products within the scope of CSA C381.1 are not intended to be tested by this Standard. Annex B specifies requirements for determining the appropriate test method (CSA C381.1 or this Standard) for measuring a product?s energy performance.1.3 ExclusionsThe following are not covered by this Standard:a) a "medical device" as defined in Section 1 of the Canadian Medical Devices Regulations;b) back-up battery chargers; andc) dc output uninterruptible power supply (UPS).1.4 TerminologyIn 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; "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.
