Water quality - Guidance and requirements for designing an interlaboratory trial for validation of analytical methods (ISO/TS 7013:2023)
This document specifies requirements and recommendations for the design and execution of an interlaboratory comparison for validation of new standardized analytical methods in the field of water analysis, e.g. the number of participating laboratories and time schedules. This document is based on ISO 5725-1 and ISO 5725-2.
NOTE The scope of other standards in the field of interlaboratory comparison, such as ISO/IEC 17043 and ISO 13528, is proficiency testing of analytical laboratories and not interlaboratory comparison for the validation of analytical methods.

In diesem Dokument werden Anforderungen und Empfehlungen für die Planung und Durchführung eines Ringversuchs zur Validierung neuer genormter Analysenverfahren im Bereich Wasseranalytik festgelegt, z. B. die Anzahl der teilnehmenden Labore und Zeitpläne. Dieses Dokument beruht auf ISO 5725 1 und ISO 5725 2.
ANMERKUNG Der Anwendungsbereich anderer Normen zum Thema Ringversuche, wie etwa ISO/IEC 17043 [3] und ISO 13528 [1], sind Eignungsprüfungen von Analyselaboren, nicht Ringversuche zur Validierung von Analysenverfahren.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.

Introduction
The final validation step during standardization of an analytical method is the evaluation of
performance through an interlaboratory trial to demonstrate that a new method is fit for purpose.
This document is intended to assist persons organizing interlaboratory trials to design and organize
international interlaboratory comparisons for the validation of new standardized physical, chemical
and biochemical methods for water analysis.
