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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15839 was prepared by Technical Committee ISO/TC 147, Water quality.

water — Specifications and performance tests
WARNING — Persons using this International Standard should be familiar with normal laboratory
practice. This standard does not purport to address all of the safety problems, if any, associated with
its use. It is the responsibility of the user to establish appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
1 Scope
This International Standard describes the performance testing of on-line sensors/analysing equipment for
water. The standard is applicable to most sensors/analysing equipment, but it is recognized that, for some
sensors/analysing equipment, certain performance tests cannot be carried out. This International Standard
defines an on-line sensor/analysing equipment for water quality measurements;
defines terminology describing the performance characteristics of on-line sensors/analysing equipment;
specifies the test procedures (for laboratory and field) to be used to evaluate the performance
characteristics of on-line sensors/analysing equipment.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
accepted reference value
value that serves as an agreed reference value for comparison, and which is derived as:
a) an assigned or certified value based on experimental work of some national or international organization;
b) a consensus or certified value based on collaborative experimental work;
c) a theoretical or established value based on scientific principles;
d) when a), b) and c) are not available, the expectation of the (measurable) quantity, i.e. the mean of a
number of measurements.
[Adapted from ISO 5725-1:1994]
3.2
accuracy
closeness of agreement between a measured value and the accepted reference value
NOTE The term accuracy, when applied to a set of measured values, involves a combination of random components
and a common systematic error or bias component.
[Adapted from ISO 5725-1:1994]
3.3
analytical chain
set of instruments and actions covering all the steps involved in determining a reference value in a field test,
including sampling, fractioning, conditioning, storage and transportation of the sample to the laboratory for
analysis
3.4
availability
〈measurement chain〉 percentage of the full measurement period during which the measurement chain is
available for making measurements
NOTE The full measurement period is the period which includes all specified automatic or manual maintenance
operations at least once
cf. up-time (3.42)
3.5
bias
consistent deviation of the measured value from an accepted reference value
NOTE Bias is the total systematic error as contrasted to random error. There may be one or more systematic error
components contributing to the bias. A larger systematic difference from the accepted reference value is reflected by a
larger bias value.
[Adapted from ISO 5725-1:1994]
3.6
blank solution
solution, free of determinand, to which the on-line sensor/analysing equipment is exposed in the same way as
calibration or sample solutions
NOTE The value of the measurement is known as the “blank value”.

ISO 15839:2003(E)
3.7
calibration solution
solution containing a substance or mixture of substances giving a defined value of the determinand and used
for calibration of the on-line sensor/analysing equipment
cf. reference material (3.30)
3.8
calibration procedure
set of operations that establishes, under specified conditions, the relationship between the amount or quantity
of calibrant and the response indicated by the on-line sensor/analysing equipment
3.9
coefficient of variation
ratio of the standard deviation of the on-line sensor/analysing equipment to the mean of the working range of the
equipment
[Adapted from ISO 8466-1:1990]
3.10
day-to-day repeatability
precision under day-to-day repeatability conditions
3.11
day-to-day repeatability conditions
conditions whereby independent test results are obtained with the same method on identical test items in the
same laboratory by the same operator using the same equipment and reagents over several days
3.12
delay time
time interval between the instant when the on-line sensor/analysing equipment is subjected to an abrupt
change in determinand value and the instant when the
