Ships and marine technology — Piping and machinery — Ballast water sampling and analysis — Part 1: Discharge sampling port
ISO 11711-1:2013 provides guidance to shipboard personnel and other concerned parties on the materials, design, and installation of equipment used to take samples of treated ballast water from the ballast water discharge pipe onboard a vessel. The purpose of the sampling system is to enable the taking of a representative sample in order to verify that the ballast water management system (BWMS) is working as designed, i.e. the treatment is reducing the concentration of living organisms to levels established in discharge standards. The intent of the sampling installation is to provide a representative sample of the ballast water effluent with adequate pressure and flow.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

Introduction
This part of ISO 11711 provides guidance to shipboard personnel and other concerned parties on the
design and installation of the sampling port required to obtain representative samples of ballast water
from the ballast water discharge piping prior to discharge. Parts 2 and 3 of this part of ISO 11711 will
provide guidance on how to handle and process the samples on board the vessel, and on how to analyse
the samples to determine compliance with ballast water discharge requirements, respectively.
Although it is recognized that sampling of the actual tanks is possible through various methods, the
primary concern for port and flag state officials is verification of the efficacy of the ballast water
management system (BWMS) in preventing the unwanted discharge. The only true way to measure
what is being sent overboard in ballast water is to sample the ballast discharge as near as possible to the
actual overboard.
NOTE This part of ISO 11711 is written for sampling after the BWMS treatment, and prior to the discharge
of ballast water, in order to assess the effectiveness of the BWMS. However, sample ports can also be installed
elsewhere on a vessel for other purposes, such as experimental assessment of prototype BWMSs. In such cases,
similar sample ports could also be installed prior to the treatment (ballast uptake side) in order to make a
comparison between the ballast uptake and discharge.

1 Scope
This part of ISO 11711 provides guidance to shipboard personnel and other concerned parties on the

taking of a representative sample in order to verify that the ballast water management system (BWMS)
is working as designed, i.e. the treatment is reducing the concentration of living organisms to levels
established in discharge standards. The intent of the sampling installation is to provide a representative
sample of the ballast water effluent with adequate pressure and flow.
