船舶和海洋技术 水生公害物种 压载水排放合规监测装置性能评估方法

[中文适用范围]： 本文件规定了评估特定类别分析仪器（称为合规性监测设备 (CMD)）性能的方法。这些仪器旨在检查压载水，以确定样品是否达到或超过活体或可存活生物的浓度限值。这些限值包括国际海事组织 (IMO) 规则 D-2 在《国际船舶压载水和沉积物控制和管理公约》[4] 中规定的限值或国家或地区当局采用的其他排放标准 (DS)。测试方法测量 CMD 与参考方法之间的一致性，以计算正确度和精确度。正确度和精确度都只考虑简单的分类结果（例如“达到”或“超过”DS）。性能指标可靠性通过 CMD 不可用或未按预期运行的情况的频率来量化。测试和试验的设置基于 CMD 制造商的声明，例如 CMD 针对的 DS 组，以及已知的限制，包括基于样品水盐度的限制。注：如果最终用户需要，可以按照此通用测试方法进行额外的测试和试验。确定实验能力的指南见 7.5。本文件提供了定制测试的指南，以评估制造商的声明或解决最终用户感兴趣的可选因素。本文件不设定或推荐任何性能指标的成功标准，因为这些标准由最终用户适当定义。 [外文原描述]： This document specifies methods to evaluate the performance of a specific class of analytical instruments, known as compliance monitoring devices (CMDs). These instruments are designed and intended to examine ballast water to determine whether a sample meets or exceeds limits for the concentration of living or viable organisms. These limits include those specified by the International Maritime Organization (IMO) Regulation D-2 in the International Convention for the Control and Management of Ships' Ballast Water and Sediments [ 4 ] or other discharge standards (DS) adopted by national or regional authorities. The test methods measure the agreement between the CMD and a reference method to calculate trueness and precision. Both trueness and precision consider only simple, categorical outcomes (e.g. “meets” or “exceeds” the DS). The performance metric reliability is quantified by the frequency of instances when the CMD is not available or is not operating as expected. The set of tests and trials is based upon the CMD manufacturer claims, such as the DS group(s) targeted by the CMD, and known limitations, including those based upon the salinity of the sample water. NOTE Additional tests and trials, if required by the end-user, can follow this general test method. Guidance on determining experimental power is found in 7.5 . This document provides guidance for customizing the tests to evaluate the claims of the manufacturer or to address optional factors of interest to the end-users. This document does not set or recommend success criteria of any performance metric, as these are appropriately defined by the end-users.
