Minimum energy performance technical specification for passenger tires 乘用车轮胎最低能耗性能技术规范
发布日期: 2021-03-01
前言:这是CSA SPE-115《乘客轮胎最低能耗性能技术规范》的第一版。CSA集团承认,本技术规范的制定部分是由于加拿大自然资源部的财政支持。范围:1.1概述本技术规范旨在制定一项可执行的技术规范,以确定加拿大新进口轻型车辆轮胎的最低能效和湿抓性能要求。其目的是根据NRCan管辖下的《能源效率法案》对能源效率进行监管,并根据加拿大交通部管辖下的《机动车安全法案》对湿抓地力进行监管。1.2用户本技术规范供a)监管机构使用;b) 轮胎制造商;c) 原始设备(OE)车辆制造商; d) 测试设施和实验室;ande)轮胎进口商/分销商。1.3应用本技术规范适用于设计用于1975年1月1日当天或之后制造的轻型车辆的新型充气子午线轮胎(根据CMVSS 139)。1.4例外情况本技术规范不适用于轻型卡车(LT)轮胎和C型轮胎;b) 胎面花纹深度为14.3毫米(18/32英寸)或更大的轮胎;c) 速度符号大于V的轮胎;d) 摩托车轮胎;e) 公路拖车专用轮胎(ST);f) 农业服务中的农用机具(FI)轮胎,间歇公路使用;g) 轮辋直径小于等于8英寸的轮胎;h) 临时使用备用轮胎;i) 使用螺柱制造的冬季轮胎;j) 斜交轮胎;andk)设计用于比赛的赛车轮胎。1.5本技术规范中的术语“应”用于表示要求,即:。 e、 ,用户为遵守技术规范而应满足的规定;“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技术规范范围内允许的选项。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。
Preface:This is the first edition of CSA SPE-115,Minimum energy performance technical specification for passenger tires.CSA Group acknowledges that the development of this Technical Specification was made possible, in part, by the financial support of Natural Resources Canada.Scope:1.1 GeneralThe intent of this Technical Specification is to create an enforceable Technical Specification that will establish minimum energy efficiency and wet grip performance requirements for new and imported light-duty vehicle tires in Canada. The intent is to regulate energy efficiency under theEnergy Efficiency Actunder NRCan's jurisdiction and to regulate wet grip under theMotor Vehicle Safety Actunder Transport Canada's jurisdiction.1.2 UsersThis Technical Specification is intended for use bya) regulatory agencies;b) tire manufacturers;c) original equipment (OE) vehicle manufacturers;d) testing facilities and laboratories; ande) tire importers/distributors.1.3 ApplicationThis Technical Specification applies to new pneumatic radial tires designed for use on light duty vehicles that were manufactured on or after January 1, 1975 (per CMVSS 139).1.4 ExclusionsThis Technical Specification does not apply toa) light truck (LT) tires and C-type tires;b) tires with a tread depth of 14.3 mm (18/32 in) or greater;c) tires with a speed symbol greater than V;d) motorcycle tires;e) special tires (ST) for trailers in highway service;f) tires for use on farm implements (FI) in agricultural service with intermittent highway use;g) tires with rim diameters of 8 in and below;h) temporary use spare tires;i) winter tires that are manufactured with studs;j) bias ply tires; andk) racing tires designed for competition use.1.5 TerminologyIn this Technical Specification, "shall" is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the Technical Specification; "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 Technical Specification. 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.
