Glossary
Volumetric analytical techniques refers to spectrophotometric and titrimetric
techniques.
Specified standards refer to those recognised by the Standards Institute of
New Zealand or equivalent for calibration.
Certified reference value is a value traceable to a national or international standard.
Laboratory procedures refer to documented systems or processes of operation,
which may be found in a SOP manual, quality management system or protocol
system documentation. These procedures are external and/or internal laboratory
requirements governing laboratory work.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
