本文件向压载水取样小组或其他相关方提供了有关选择和使用取样装置的要求和建议，以从根据ISO 11711-1安装的取样口收集和处理船上压载水排放样品。本文件包括取样过程概述，以及关于样品探针的设计和维护、必要的样品流速、包含样品流量控制以保持代表性采样条件的样品采集装置以及后续分析样品的处理的讨论。本文件主要涉及压载水排放样品的收集。然而，考虑到环境（与处理水相反）水中的预期有机物浓度，考虑到适当的样本量，它也可以应用于采样。注意了吗虽然本文件重点关注船舶上的安装，但它可以用于陆基设施。

This document provides requirements and recommendations to ballast water sampling teams or other concerned parties on the selection and use of sampling apparatus to collect and process ballast water discharge samples aboard a ship from sample ports installed in accordance with ISO 11711-1. It includes an overview of the sampling process, and a discussion on the design and maintenance of sample probes, the necessary sample flow rates, the sample collection devices that incorporate sample flow control to maintain representative sampling conditions, and the handling of samples for subsequent analyses.This document primarily addresses the collection of ballast water discharge samples. However, it can also be applied to uptake samples with consideration of appropriate sample volumes given anticipated organism concentrations in ambient (as opposed to treated) waters.NOTE       While this document is focused on installations aboard a ship, it can be used for land-based facilities.
