1.0.1为规范电子工程建设的基本术语及其定义,实现术语标准化,制定本标准。1.0.2本标准适用于电子工程建设的规划、咨询、设计、工程监理、工程管理等工程服务以及教学、科研及其他相关领域。1.0.3电子工程建设文件、图纸、科技文献使用的术语,除应符合本标准外,尚应符合现行有关标准的规定。
本标准规定了核电工程测量各级基准网的布设原则、技术规格、作业方法、成果整理提交、各级网维护、仪器使用管理等内容。本标准适用于核电站建设工程测量基准网建立的技术设计、作业,检查与验收等活动。
本标准规定了800MHz/2GHz cdma2000数字蜂窝移动通信网高速分组数据(HRPD)(第二阶段)接入终端的功能、各层性能、环境适应性、寿命、电源和充电器、外观包装及装配等方面的测试方法。本标准适用于支持UIM卡(机卡分离)及不支持UIM卡(机卡一体)的800MHz/2GHz cdma2000 HRPD(第二阶段)接入终端,对于支持UIM卡的800MHz/2GHz cdma2000 HRPD (第二阶段)接入终端,本标准所有项目均适用,对于不支持UIM卡的800MHz/2GHz cdma2000 HRPD (第二阶段)接入终端,本标准涉及到UIM卡及UIM卡接口测试的项目不适用。
The ITU Radiocommunication Assembly considering that HDTV is defined as one of the picture formats in DTV standards; that compression technology is widely used and provides adequate picture quality in SDTV and HDTV applications not only for secondary distribution to the home but also for broadcasting studio equipment; that devices for HDTV signal compression have been developed by several integrated circuit manufacturers and are available economically in the market; that compression technology makes it possible to produce digital HDTV tape cassette recorders not only for studio production applications but also for field acquisition applications.
Band segmentation between radiocommunication services can be viewed as actually eliminatingsharing by creating sub-allocations.
This European Standard is applicable to open-path absorption measurements of 'concentration ~ path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.
This part 1 of DIN EN 61996 specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for shipborne voyage data recorder (VDR) installations as required by Chapter V of the International Convention for Safety of Life at Sea (SOLAS), as amended. It takes account of IMO resolution A.694 (17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. This 2nd edition incorporates amendments according to new IMO requirements included in IMO Resolution MSC.XXX (90).
This part of IEC 61996 specifies the minimum performance requirements, technical characteristics andmethods of testing, and required test results, for simplified shipborne voyage data recorders (S-VDRs) asrequired by IMO MSC.163(78). It takes into account IMO resolution A.694(17) and is associated withIEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in thisstandard takes precedence.NOTE All text of this standard, whose wording is identical to that of IMO MSC.163(78) or A.861(20) is printed in italics, and theResolution and associated performance standard paragraph numbers are indicated in brackets.
This first part of IEC 62320 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS Base Stations, compatible with the performance standards adopted by IMO Res. MSC.74 (69), Annex 3, Universal AIS.
This European Standard is applicable to open-path absorption measurements of 'concentration × path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.
