前言:这是CSA C877《便携式电子标志的能量性能》的第一版。本标准的要求是对CAN/CSA-C22中规定要求的补充。2号207。CSA集团承认，该标准的制定部分是由BC Hydro、加拿大电力协会、效率新斯科舍省、魁北克Hydro、马尼托巴Hydro、加拿大自然资源部、安大略省能源部、安大略省电力局和SaskPower的财政支持实现的。CSA集团感谢加州能源委员会（CEC）在制定本标准时使用2013年《住宅和非住宅建筑能效标准》第24篇第6部分和第1部分的相关行政法规。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。 CSA集团已将其作为加拿大国家标准发布。范围:1.1本标准规定了确定便携式插入式发光标志性能的要求和试验程序。注:本标准范围和目标的背景信息见附录A.1.2。本标准适用于非危险场所室内或室外使用的便携式电子标志，旨在根据《加拿大电气规范》第一部分进行安装，在导体之间不超过125 V的分支电路上，涉及不超过7500 V的灯电压。1.3本标准包括以下要求:（a）内部照明标志（柜）；b） 未过滤发光二极管（LED）；和c）未过滤冷阴极/氖管。1.4本标准不包括a）室内外固定标志的要求；b） 外部照明标志； c） 不属于电子信息中心（EMC）、内部照明标志或外部照明标志的未过滤白炽灯。此例外情况仅适用于未经过滤的白炽灯的标志部分；注:1）尽管本例外情况中提到了内部照明标志，但只有由未经过滤的白炽灯组成的混合标志部分不在标志照明能量要求范围内。2） 参见第3条中未经过滤的标志的定义。d） 出口标志；e） 交通标志；电子显示器。1.5在本标准中，“应”用于表示要求，即用户为遵守本标准而有义务满足的规定；“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）以定义其应用。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 first edition of CSA C877,Energy performance of portable electric signs.The requirements of this Standard are in addition to those specified in CAN/CSA-C22.2 No. 207.CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, Canadian Electricity Association, Efficiency Nova Scotia, Hydro-Quebec, Manitoba Hydro, Natural Resources Canada, Ontario Ministry of Energy, Ontario Power Authority, and SaskPower.CSA Group is indebted to the California Energy Commission (CEC) for the use of the2013 Building Energy Efficiency Standards for Residential and Nonresidential Buildings, Title 24, Part 6 and associated administrative regulations in Part 1, in the development of this Standard.This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.Scope:1.1This Standard specifies requirements and test procedures to determine the performance of portable plug-in luminous signs.Note: Background information on the scope and objective of this Standard is provided in Annex A.1.2This Standard applies to portable electric signs for indoor or outdoor use, in nonhazardous locations, intended for installation in accordance with theCanadian Electrical Code, Part I, on branch circuits of not more than 125 V between conductors and involving lamp voltages of not more than 7500 V.1.3This Standard includes requirements fora) internally illuminated signs (cabinet);b) unfiltered light emitting diodes (LEDs); andc) unfiltered cold cathode/neon tubing.1.4This Standard does not include requirements fora) stationary indoor and outdoor signs;b) externally illuminated signs;c) unfiltered incandescent lamps that are not part of an electronic message center (EMC), an internally illuminated sign, or an externally illuminated sign. This exception applies only to portions of a sign that are unfiltered incandescent lamps;Notes:1) Although internally illuminated signs are mentioned in this exception, it is only those portions of a hybrid sign consisting of unfiltered incandescent lamps that are excluded from the sign lighting energy requirements.2) See the definition Unfiltered sign in Clause 3.d) exit signs;e) traffic signs; andf) electronic displays.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.
