本部分规定了建筑及居住区数字化技术应用的检测内容、方法和验收要求等,包括通信系统、信息系统与监控系统以及支持这些系统工程的基础设施(包括:信息网络平台、综合布线系统、电源与接地、环境、机房系统、基础系统集成等)的检测验收。 本部分适用于对建筑及居住区数字化技术应用系统的功能与质量的第三方检测,相应的改扩建系统和其他应用项目可以参照使用。
本标准规定了工业环境中及工业现场的自动化岛内和岛间的通信网络媒体安装的基本要求。本标准包括对称线缆布线和光纤布线,以及无线媒体的布线设施,但不包括无线媒体本身。其他媒体见IEC 61784-5系列标准。本标准是工业自动化岛通信网络的配套标准,尤其是对IEC 61158系列和IEC 61784系列标准中规定的通信网络。此外,本标准还包括:——ISO/IEC 24702中规定的工业环境电信综合布线的安装;——ISO/IEC 24702中规定的电信综合布线与自动化岛的特定布线之间的连接,其中,用自动化引出端(AO)代替ISO/IEC 24702的电信引出端(TO)。本标准提供解决工业自动化领域关键问题(拓扑、气候条件、振动、化学污染、EMC、功能安全、信息安全等)的指南。本标准为设计者、安装者、验证者和验收测试人员、管理和维护人员分配任务、规定和相应职责,并且/或者给予指导。
本规范适用于测试5、5E、6类等双绞线的网络线缆分析仪的校准。测试超6类、7类双绞线的网络线缆分析仪可参照使用。
To provide within the scope of the series 11073 "Health informatics" - Point-of-care medical device communication standards, the wireless infrared transport services needed to accomplish plug and play interoperability.
This part of EN 61935 specifies reference measurement procedures for cabling parameters and therequirements for field tester accuracy to measure cabling parameters identified in series EN 50173. Thisstandard does not apply to EN 50173-4.This International Standard applies when the cable assemblies are constructed of cablescomplying with the IEC 61156 family of standards, and connecting hardware as specified inIEC 60603-7 family of standards or IEC 61076-3-104 and IEC 61076-3-110. In the case wherecables and/or connectors do not comply with these standards, then additional tests may berequired.This standard is organized as follows:• reference laboratory measurement procedures on cabling topologies are specified inClause 4. In some cases, these procedures may be used in the field;• descriptions and requirements for measurements in the field are specified in Clause 5;• performance requirements for field testers and procedures to verify performance arespecified in Clause 6.This standard relates to performance with respect to 100 Ω cabling. For 120 Ω or 150 Ωcabling, the same principles apply but the measurement system should correspond to thenominal impedance level.Field tester types include certification, qualification and verification. Certification testing isperformed for the rigorous needs of commercial/industrial buildings to this standard.Qualification testing is described in IEC 61935-3. Qualification testing determines whether thecabling will support certain network technologies (e.g., 1000BASE-T, 100BASE-TX,IEEE 1394b1)). Qualification testers do not have traceable accuracy to national standards andprovide confidence that specific applications will work. Verification testers only verifyconnectivity.Throughout this document, 4-pair cabling is assumed. The test procedures described in thisstandard may also be used to evaluate 2-pair balanced cabling. However, 2-pair cabling linksthat share the same sheath with other links are tested as 4-pair cabling.
Specifies a generic telecommunications cabling system for commercial buildings that will support a multiproduct, multivendor environment. This standard was listed for public review in the 2/11/2000 issue of Standards Action. It is being resubmitted due to substantive changes to the text.
