Product Code:SAE J694 Title:Disc Wheel/Hub or Drum Interface Dimensions--Truck and Bus Issuing Committee:Truck And Bus Wheel Committee Scope:This SAE Recommended Practice contains dimensions and their tolerances concerning disc wheel to hub or drum interface areas for commercial vehicles and multipurpose passenger vehicles. Stamped disc wheels for single applications and special or less common applications are not covered in this document.This document defines wheel mounting systems and documents the dimensions and tolerances necessary to maintain serviceability, and interchangeability in the interface areas. To be consistent with ISO, it is divided into two sections (I and II). Section I is in concert with ISO 4107, describing mounting systems currently used internationally and nominated for, or included in, the international standard for bolt circle interfaces. Section II records information on current mounting systems also used in North America. Components of different mounting systems with common bolt patterns could be mis-assembled together and cause service problems. Therefore, it is important to note that each mounting system should be treated individually and their components not be intermixed.【英文标准名称】:ElectromagneticcompatibilityandRadiospectrumMatters(ERM)-ShortRangeDevices(SRD)usingUltraWideBand(UWB)technology-LocationTrackingequipmentoperatinginthefrequencyrangefrom6GHzto8,5GHz-Part1:Technicalcharacteristicsandte 【原文标准名称】:电磁兼容性和射频频谱物质(ERM).用超宽带(UWB)技术的短程装置(SRD).工作频率范围为6GHz～8.5GHz的定位跟踪设备.第1部分:技术特性和试验方法 【标准号】:EN302500-1-.2.1 【标准状态】:现行 【国别】: 【发布日期】:2008-11 【实施或试行日期】: 【发布单位】:欧洲标准学会(EN) 【起草单位】: 【标准类型】:() 【标准水平】:() 【中文主题词】:通信技术;数据电路;数据传送;电气工程;电磁兼容性;EMC;信息处理;无线电工程;无线电网络;无线电设备;无线电系统;评定;规范(验收);远程通信;测试;无线通信业务 【英文主题词】:Communicationtechnology;Datacircuit;Datatransfer;Electricalengineering;Electromagneticcompatibility;EMC;Informationprocessing;Radioengineering;Radioequipment;Radionetworks;Radioplants;Radiosystems;Ratings;Specification(approval);Telecommunication;Telecommunications;Testing;Wirelesscommunicationservices 【摘要】: 【中国标准分类号】:L06;M36 【国际标准分类号】:33_060_20 【页数】:2P.;A4 【正文语种】:英语
