IEC TS 63165:2024

Requirements for industrial water quality analyzer system – Photometry

IEC TS 63165:2024 applies to the industrial water quality analyzer system that uses a photometric method to determine the concentration of one or more chemical components in industrial water (water used in manufacturing, processing, cooling, washing, boiler, etc).
The objective of this document is to:
- specify the terminology and definitions related to the performance characteristics of a photometric industrial water quality analyzer system;
- unify the performance expression and verifying methods of such an analyzer system;
- specify the test procedures to be used in making statements on the performance characteristics of a photometric industrial water quality analyzer system.

QUALITY ANALYZER SYSTEM – PHOTOMETRY

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has repr
