Copper, lead and zinc sulfide concentrates -- Step-by-step procedure for the testing of static scales

This Technical Report outlines simple procedures to check the performance and calibration status of static scales.
The test sequence is intended for routine applications, generating results which can be used to calculate explicit
scale performance parameters (precision, bias and linearity) in accordance with the relevant equations shown in
ISO 12745, Copper, lead and zinc ores and concentrates — Precision and bias of mass measurement techniques.
It is stressed that the basic procedures described below do not replace comprehensive technical manuals
published by National Weights and Measures authorities to comply with legal and other specific requirements.

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 3.
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.
In exceptional circumstances, when a technical committee has collected data of a different kind from that which is
normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority
vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature
and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.
Attention is drawn to the possibility that some of the elements of this Technical Report may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

2 General Information
ISO 12745 provides a general summary of testing principles and procedures for weighbridges (in 5.3), hopper
scales (in 5.4), gantry scales (in 5.5) and platform scales (in 5.6), augmented by a list of test mass categories in
clause 6.
Weighbridges, hopper and platform scales represent the most common systems encountered in the context of
concentrate mass determinations for commercial consignments. Although the principles of testing are similar,
details vary depending on the availability and number of certified weights and the level of automation (in the case of
hopper scales having built-in reference weights).
3 Frequency of testing
The frequency of in-house and routine scale performance tests (in addition to mandatory certification intervals
stipulated by regulatory authorities) observed in practice ranges from none to as high as three times per
consignment in the case of some fully automated weighing hopper installations. The
