Ships and marine technology — Aquatic nuisance species — Part 1: Ballast water discharge sample port
This document specifies requirements for the design and the fitting arrangements of ballast water discharge sample ports. In coordination with the vessel, a suitable sample collection probe is installed into the shipboard sample port as needed to collect ballast samples, and the port is sealed with a blind flange at other times. This document addresses the location of sample ports to accommodate representative sampling, and it standardizes the presentation of the port to accommodate various probe configurations. It provides specifications for a return port to the ballast line downstream of the sample collection port, allowing processed sample water to be returned to the ballast pipe. The appropriate sample probe and other sample collection apparatus is determined by the sample collection team according to the requirements of ISO 11711‑2. NOTE The distinction between the sample port discussed in this document and the sample probe discussed in ISO 11711-2 is worth noting. The sample port is a permanent apparatus designed and installed in the ship's ballast piping to accept multiple sample probe configurations. The sample probe is a temporarily installed water collection pipe designed by the sampling party to mate with the sample port and to meet the measurement objectives of the sample. This document is applicable to ships with a ballast discharge pipe size of DN 100 or greater, with turbulent flows. Guidance for smaller ballast pipe diameters is given in Annex A. This document primarily addresses the collection of ballast water discharge samples. Optional requirements for installation of sample ports intended to collect uptake samples are provided in Annex B.

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 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www .iso .org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 8, Ships and marine technology.
This second edition cancels and replaces the first edition (ISO 11711-1:2013), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The previous edition did not address apparatus needed to collect representative samples of ballast
water, nor did it provide procedures for handling or analysing the samples after they have been
collected. Accordingly, this second edition of ISO 11711-1 is intended to be complemented with
other two Parts in the ISO 11711 series.
— The previous edition provided guidance on the design of "sample ports;" they are now known as
"sample probes."
— This edition clarifies issues encountered with the previous edition and provides additional
information:
— A semi-permanently installed probe could become hazardous to ship operations if there is
excessive bio-fouling in or corrosion of the pipe.
— The first edition did not contain sufficient details to allow for multiple available sample probe
configurations and installation methods.
— The end user is now addressed in each of the parts of the ISO 11711 series. For example, this
document is intended for ship owners, designers and crew for accessing the main ballast pipe for
sampling; ISO 11711-2 is intended for port state control or other sampling parties; a future Part will
be intended for personnel analysing the samples.
A list of all the parts in the ISO 11711 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

ISO 11711-1:2019(E)
Introduction
This document provides guidance to shipboard personnel and other concerned parties on designs,
installations and procedures required to obtain representative samples of ballast water from the
ballast water discharge piping prior to discharge. ISO 11711-1 defines arrangements for shipboard
ballast piping and fittings that are independent of the sampling apparatus used by sampling teams.
1)
ISO 11711-2 will provide guidance on the selection and use of sampling apparatus needed to collect
and process the samples on board the vessel. These concepts are illustrated in Figure 1. A future part
will provide methodologies to analyse the samples and determine compliance with ballast water
discharge regulations.
Sampling is intended to determine whether ballast water is in compliance with regulatory discharge
standards, such as during the installation or evaluation of ballast water treatment equipment, periodic
ballast water discharge assessments or during a port state control inspection of the ballast water being
discharged.
The sampling guidance provided by the ISO 11711 series is intended to support measurement of
organism counts in ballast discharge piping consistent with the requirements of the International
Maritime Organisation (IMO) D-2 discharge standard. Such measurement requires the collection and
analysis of representative samples, i.e. the makeup of the sample is representative of the water flowing
in the ballast pipe over the period of sample collection.
The guidance provided by the ISO 11711 series is valid only for turbulent flows within the ballast
discharge pipe. Selecting appropriate sample probes and controlling sample flows to meet
representative sampling constraints will be discussed in ISO 11711-2.

Ballast water discharge sample port
1 Scope
This document specifies requirements for the design and the fitting arrangements of ballast water
discharge sample ports.
In coordination with the vessel, a suitable sample collection probe is installed into the shipboard sample
port as needed to collect ballast samples, and the port is sealed with a blind flange at other times. This
document addresses the location of sample ports to accommodate representative sampling, and it
standardizes the presentation of the port to accommodate various probe configurations. It provides
specifications for a return port to the ballast line downstream of the sample collection port, allowing
processed sample water to be returned to the ballast pipe. The appropriate sample probe and other
sample collection apparatus is determined by the sample collection team according to the requirements
of ISO 11711-2.
NOTE The distinction between the sample port discussed in this document and the sample probe discussed
in ISO 11711-2 is worth noting. The sample port is a permanent apparatus designed and installed in the ship's
ballast piping to accept multiple sample probe configurations. The sample probe is a temporarily installed water
collection pipe designed by the sampling party to mate with the sample port and to meet the measurement
objectives of the sample.
This document is applicable to ships with a ballast discharge pipe size of DN 100 or greater, with
turbulent flows. Guidance for smaller ballast pipe diameters is given in Annex A.
This document primarily addresses the collection of ballast water discharge samples. Optional
requirements for installation of sample ports intended to collect uptake samples are provided in
Annex B.
