Definitions
Gravimetric in the context of this unit standard means
determination of volume by weighing.
International Organisation of Legal Metrology (OIML) is
based in Paris and is an organisation made up of
member states. New Zealand is a member state.
OIML makes recommendations covering aspects of
legal metrology.
Legal Metrology is part of metrology relating to activities
that result from statutory requirements and concern
measurements.
Maximum permissible error (mpe) is the extreme value
of an error permitted by the mandatory requirements.
Metrology is the science of measurement.
Organisation in the context of this unit standard is the
Ministry of Consumer Affairs Measurement and Product
Safety Service.
Organisational requirements in the context of this unit
standard includes policy and procedures of the Ministry
of Consumer Affairs Measurement and Product Safety
Service.
Public Sector covers all publicly owned organisations
which are connected to the institution of New Zealand
government, both central and local, and which include
public service, crown entities, non-uniformed staffs of
the services and forces, offices of Parliament, and local
authorities.
Public Service is part of the State sector, and consists
of all the ministries and departments of state which
carry out core government business which are listed in
the First Schedule of the State Sector Act 1988.
State Sector applies to all national institutions of central
government.
Standard means a physical representation of any
standard of measurement.
Uncertainty is a measure of the precision by which a
value is known. The amount by which a true value may
differ from a measured value at a given confidence
level.
