本标准规定了压力传感器(以下简称传感器)性能的试验条件、试验的一般规定、试验项目及试验方法、数据计算及处理。本标准适用于压力传感器(包括绝压传感器、差压传感器、表压传感器和负压传感器)。
除了GB/T 18268.1的要求外,GB/T 18268的本部分更详细的规定了下列设备的试验配置、工作条件和性能判据:低压配电系统防护设施的试验、测量或监控设备;由电池和(或)被测电路供电的设备;便携式设备。此类设备包括但不限于GB/T 18216(或IEC 61557)确定的电压检测器、万用表、绝缘电阻测试仪、接地导通电阻测试仪、环路阻抗测试仪、“剩余电流保护装置测试仪”(RCD测试仪)和相序测试仪。制造商应规定设备的预定使用环境,并从GB/T 18268.1的规范中选择适用的试验等级。
本标准规定了交流1 100 kV气体绝缘金属封闭开关设备的使用条件、额定值、设计与结构、试验、选用导则、运输、储存、安装、运行和维护等要求。本标准适用于1 100 kV户内和户外安装、频率为50 Hz的单极封闭SF<下标6>气体绝缘金属封闭开关设备,其绝缘的获得至少部分通过绝缘气体而不是处于大气压下的空气。为了便于本标准的使用,术语“GIS”和“开关设备”均用于表述“气体绝缘金属封闭开关设备”。本标准涵盖的气体绝缘金属封闭开关设备是由可以直接连接在一起的各独立元件构成,而且这些元件只能按这种方式运行。根据需要,本标准对于构成GIS的各个独立元件的相关标准进行了完善和补充。
本标准规定了地下水检测移动实验室(以下简称移动实验室)的术语和定义、技术要求、试验方法、标志、文件、运输及贮存。本标准适用于陆地使用的可进行地下水的感官、无机物、有机物、微生物等指标检测的移动实验室。
本规范适用于新建、扩建和改建的民用建筑和一般工业建筑的电气工程电磁兼容的设计、施工、检测及验收。
本标准规定了鱼雷射击导引海上验证试验的试验项目及内容、试验程序和考核验收方法等。本标准适用于新研或改进潜艇鱼雷射击导引海上验证试验及试验的评定。
本标准规定了空间用光纤陀螺惯性测量组合试验的一般要求、温度建模试验、性能试验及环境试验的项目和方法、试验中断处理及试验结果处理等内容。本标准适用于空间用光纤陀螺惯性测量组合的试验。
本部分规定了舰载导航雷达(以下简称雷达)的修理性能指标要求和检查验收条件。 本部分适用于雷达的修理和检验。
本规范规定了海军海洋水文气象自动观测系统的通用要求。本规范适用于在海军海洋站和观通站上安装、使用的海洋水文气象自动观测系统(以下简称“系统”)的设计、生产、试验与验收,其它水文气象自动观测系统可参照使用。
本标准规定了火力发电厂热控系统检修运行维护的内容、方法和技术管理应达到的标准。本标准适用于火力发电厂已投产机组热控系统的检修和日常运行维护工作。
DIN EN ISO 15970 gives requirements and procedures for the measurement of the properties of natural gas that are used mainly for volume calculation and volume conversion: density at reference and at operating conditions, pressure, temperature and compression factor. Only those methods and instruments are considered that are suitable for field operation under the conditions of natural gas transmission and distribution, installed either in-line or on-line, and that do not involve the determination of the gas composition. This International Standard gives examples for currently used instruments that are available commercially and of interest to the natural gas industry.
This British Standard gives recommendations for, and guidance on,the design for the installation of instrumentation of measurementand control systems in the process industry, and the implementationand commissioning of this installation. It is intended to be used asa manual of good practice on the site and also to assist those whodesign the installation.
This European Standard describes a hot-wire (parallel) method for the determination of thermal conductivity ofrefractory products and materials. It is applicable to dense and insulating shaped products and to powdered orgranular materials (see 6.2), for thermal conductivities of less than 25 W/m.K. The limits are imposed by thethermal diffusivity of the test material and therefore by the dimensions of the test pieces; higher thermalconductivities can be measured if larger pieces are used. Electrically conducting materials cannot bemeasured.NOTE 1 The thermal conductivity of products with a hydraulic or chemical bond can be affected by the appreciableamount of water that is retained after hardening or setting and is released on firing. These materials may therefore requirepre-treatment; the nature and extent of such pre-treatment and the period for which the test piece is held at themeasurement temperature as a preliminary to carrying out the test, are details that are outside the scope of this standardand should be agreed between the parties concerned.NOTE 2 In general it is difficult to make measurements on anisotropic materials and the use of this method for suchmaterials should also be agreed between the parties concerned.
