本欧洲标准规定了用于在线或在线操作位置的便携式和固定位置测量装置（MD）的一般要求和性能测试程序，用于测量水中的物理化学性质。它不包括在线设备，如化学测试套件和离线设备，如实验室分析仪。 一般要求包括MD需要满足用户应用程序的功能设施和需要包含在相关文档中的信息。 测试程序规定了在确定MD的关键性能特征时要使用的统一方法。性能测试包括在实验室和现场条件下进行的测试。 定义了对测试数据进行评估的统计程序。应当认识到，对于某些设备，某些测试程序不适用。 附件A中详细列出了用于监测废水排放和接收水的选择用途管理系统的性能特征的示例值，以供指导。 本欧洲标准要求MD的制造商提供比EN ISO 15839:2006 [5]更多的技术数据进行验证。因此，EN ISO 15839将对希望表征新设备的制造商有更大的帮助

This European Standard specifies general requirements and performance test procedures for portable and fixed position measuring devices (MDs) that are used in an in-line or online operating position to measure physical and chemical determinands in water. It excludes at-line devices, such as chemical test kits, and off-line devices, such as laboratory analysers. The general requirements include functional facilities that MDs need to meet users’ applications and information that need to be included in associated documents. The test procedures specify uniform methods to be used when determining key performance characteristics of MDs. The performance tests comprise testing carried out under laboratory and field conditions. Statistical procedures are defined for evaluation of the test data. It is recognized that for some devices certain test procedures are not applicable. Example values for performance characteristics for a selection of MDs for monitoring waste water effluents and receiving waters are detailed in Annex A for guidance. This European Standard requires the manufacturer of a MD to provide more technical data for verification than does EN ISO 15839:2006 [5]. Consequently, EN ISO 15839 will be of greater assistance to manufacturers wishing to characterize a new device whereas this European Standard is more focussed on user requirements for the verification of manufacturer’s claims.
