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
Implementation of this test report format is informative with regard to the implementation of
ISO 4064-1:2024|OIML R 49-1:2024 and ISO 4064-2:2024|OIML R 49-2:2024 in national regulations;
however, its implementation is required within the framework of the OIML Certificate System for Measuring
Instruments [ISO 4064-2:2024|OIML R 49-2:2024, 11.1].
Clause 4 shows the required format of a type evaluation report for a complete or combined water meter.
A type evaluation report for a separable calculator (including indicating device) or a measurement transducer
(including flow or volume sensor) requires a similar format. However, some modifications to the tables may
be required because a large number of variations in the design of these separable units is possible.
Some examples of tables for presenting the test results for separable units are shown in Clause 5 for initial
verifications. These tables can also be adapted for type evaluation reports.

unambiguous visual indication of the indicated volume
6.7.1.1 The indicating device shall include visual means for testing and
calibration.
6.7.1.1 The indicating device may include additional elements for test-
ing and calibration by other methods, e.g. for automatic testing
and calibration
Unit of measurement and its placement
6.7.1.2 The indicated volume of water shall be expressed in cubic
metres
6.7.1.2 The symbol m shall appear on the dial or immediately adja-
cent to the numbered display

Colour coding for indicating device
6.7.1.4 The colour black should be used to indicate the cubic metre and
its multiples
6.7.1.4 The colour red should be used to indicate sub-multiples of a
cubic metre
6.7.1.4 The colours shall be applied to either the pointers, indexes,
numbers, wheels, discs, dials or aperture frames
6.7.1.4 Other means of indicating the cubic metre may be used pro-
vided there is no ambiguity in distinguishing between the
primary indication and alternative displays, e.g. sub-multiples
for verification and testing
Types of indicating device: Type 1 — Analogue device
6.7.2.1 The indicated volume shall be shown by continuous movement
of either:
a) one or more pointers moving relative to graduated scales;
or
b) one or more circular scales or drums each passing an index
6.7.2.1 The value expressed in cubic metres for each scale division
n
shall be of the form 10 , where n is a positive or a negative
whole number or zero, thereby establishing a system of consec-
utive decades.

6.7.2.1 The scale shall be graduated in values expressed in cubic me-
tres or accompanied by a multiplying factor
(×0,001; ×0,01; ×0,1; ×1; ×10; ×100; ×1 000 etc.)
6.7.2.1 Rotational movement of the pointers or circular scales shall be
clockwise
6.7.2.1 Linear movement of pointers or scales shall be left to right
6.7.2.1 Movement of numbered roller indicators shall be upwards
Types of indicating device: Type 2 — Digital device
6.7.2.2 The indicated volume is given by a line of digits appearing in
one or more apertures
6.7.2.2 The advance of one digit shall be completed while the digit of
the next immediately lower decade changes from 9 to 0
6.7.2.2 The apparent height of the digits shall be at least 4 mm
6.7.2.2 For non-electronic devices, movement of numbered roller indi-
cators (drums) shall be upwards
6.7.2.2 For non-electronic devices, the lowest value decade may have
a continuous movement, the aperture being large enough to
permit a digit to be read without ambiguity
6.7.2.2 For electronic devices with non-permanent displays the vol-
ume shall be able to be displayed at any time for at least 10 s
6.7.2.2 For electronic devices, the meter shall provide visual checking
of the entire display which shall have the following sequence:
— for seven segment type displaying all the elements (e.g. an
“eights” test); and
— for seven segment type blanking all the elements (a
“blanks” test).
For graphical displays, an equivalent test is required to
demonstrate that display faults cannot result in any digit being
misinterpreted.
Each step of the sequence shall last at least 1 s
Types of indicating device: Type 3 — Combination of analogue and digital devices
6.7.2.3 The indicated volume is given by a combination of type 1 and
type 2 devices and the respective requirements of each shall
apply
Verification devices — General requirements
6.7.3.1 Every indicating device shall provide means for visual, non-am-
biguous verification testing and calibration
6.7.3.1 The visual verification may have either a continuous or a dis-
continuous movement
6.7.3.1 In addition to the visual verification display, an indicating de-
vice may include provisions for rapid testing by the inclusion of
complementary elements (e.g. star wheels or discs), providing
signals through externally attached sensors.

6.7.3.2.1 For analogue or digital indicating devices with continuous
movement of the first element, the verification scale interval
may be formed from the division into 2, 5 or 10 equal parts of
the interval between two consecutive digits of the first ele-
ment. Numbering shall not be applied to these divisions
6.7.3.2.1 For digital indicating devices with discontinuous movement of
the first element, the verification scale interval is the interval
between two consecutive digits or incremental movements of
the first element
6.7.3.2.2 On indicating devices with continuous movement of the first
element, the apparent scale spacing shall be not less than 1 mm
and not more than 5 mm
6.7.3.2.2 The scale shall consist of either:
a) lines of equal thickness not exceeding one quarter of the
scale spacing and differing only in length; or
b) contrasting bands of a constant width equal to the scale
spacing
6.7.3.2.2 The apparent width of the pointer at its tip shall not exceed
one-quarter of the scale spacing and in no case shall it be great-
er than 0,5 mm
Resolution of the indicating device
6.7.3.2.3 The sub-divisions of the verification scale shall be small
enough to ensure that the resolution of the indicating device
does not exceed 0,25 % of the actual volume for accuracy class
1 meters, and 0,5 % of the actual volume for accuracy c
