序言这是ANSI Z21的第三版。73/CSA 11.1,便携式气体营地灯。它取代了2000年和2011年出版的前两个版本。范围1。1本标准适用于便携式气体营地灯:a)使用丙烷、丁烷、液化石油气或其任何组合;b)仅限于户外。1.2使用材料或结构形式与本规定中详述的不同的灯具和部件可根据本规定的意图进行检查和测试,如果发现其具有令人满意的等效性,则可予以认可。
1.3本标准适用于完全由新的未使用部件构成的灯具。1.4除非另有规定,否则本标准中提及的所有psi均应视为表压。1.5如果本标准中给出的测量值之后是其他单位的等效值,则应将第一个规定值视为规范,除非第4.10条“说明”和第4.11.4条另有说明。1.6附件A“加拿大独有的项目”包含加拿大独有的条款。1.7第2条“参考出版物”包含本标准中特别引用的标准列表,以及这些标准的来源。
1.8本标准包含相当于码/磅数量的国际单位制(公制),目的是允许以国际单位制(公制)单位使用标准。(IEEE/ASTM SI 10,美国国家米制实践标准,或ISO 80000-1:2009,数量和单位——第1部分:总则用作从码/磅数量进行米制转换的指南。)如果规定了测量值和其他单位的相应值,则应将第一个规定值视为要求。给定的相应值可能是近似值。如果一个测量值和其他单位的相应值都被规定为引用的标记要求,则应提供第一个或两个规定的单位。
1.9在本标准中,“应”用于表示要求,即用户为遵守本标准而应满足的规定;“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。
PrefaceThis is the third edition of ANSI Z21.73/CSA 11.1, Portable type gas camp lights. It supersedes the previous editions published in 2000 and 2011.Scope1.1 This Standard applies to portable type gas camp lights for use: a) with propane, butane, liquefied petroleum gas or any combination thereof; and b) outdoors only. 1.2 Lights and components employing materials or having forms of construction differing from those detailed in these provisions may be examined and tested according to the intent of the provisions and if found to be satisfactorily equivalent, may be given recognition. 1.3 This Standard applies to lights constructed entirely of new, unused parts. 1.4 All references to psi throughout this Standard are to be considered gauge pressures unless otherwise specified. 1.5 If a value for measurement, as given in this Standard, is followed by an equivalent value in other units, the first stated value is to be regarded as the specification, except as noted in Clause 4.10, Instructions, and Clause 4.11.4. 1.6 Annex A, Items Unique to Canada, contains provisions that are unique to Canada. 1.7 Clause 2, Reference publications, contains a list of standards specifically referenced in this Standard, and sources from which these standards may be obtained. 1.8 This Standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the Standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units - Part 1: General is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both are to be provided. 1.9 In this Standard, "shall" is used to express a requirement, i.e., a provision that the user shall 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.
