标准范围

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，以确定样品是否符合或超过活生物体的浓度限值。这些限值包括《国际船舶压载水和沉积物控制和管理公约》[4]中国际海事组织(IMO)D-2条例或国家或地区当局采用的其他排放标准(DS)规定的限值。测试方法测量CMD和参考方法之间的一致性，以计算真实性和精确度。真实性和精确性都只考虑简单的、分类的结果（例如。g.“符合”或“超过”DS）。性能度量可靠性通过CMD不可用或未按预期运行时的实例频率来量化。该组测试和试验基于CMD制造商声明，如CMD针对的DS组和已知限制，包括基于样品水盐度的限制。笔记？如果最终用户需要，可以遵循本通用测试方法进行额外的测试和试验。确定实验功率的指导见7.5。本文件为定制测试提供了指导，以评估制造商的声明或解决最终用户感兴趣的可选因素。本文档不设置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。

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.
