Explanatory notes
1
This unit standard is intended for, but not restricted to, workplace assessment. The
range statements across the unit standard can be applied according to
industry-specific equipment, procedures, and processes.
2
Safety of personnel and plant must be prioritised during assessment against this unit
standard. If the client safety requirements are not met assessment must stop.
3
Performance of the evidence requirements must comply with all current legislation,
especially the Electricity Act 1992, and any regulations and codes of practice
recognised under that statute; the Health and Safety in Employment Act 1992; and
the Resource Management Act 1991. Electricity supply industry codes of practice
and documented industry procedures include the current version of the Safety
Manual – Electricity Industry (SM-EI) (Wellington: Electricity Engineers’ Association).
A full list of current legislation and industry codes is available from the Electricity
Supply Industry Training Organisation, PO Box 1245, Hamilton 3240.

Industry requirements include all asset owner requirements; manufacturers’
specifications; and enterprise requirements. Enterprise requirements may include
the documented workplace policies, procedures, specifications, business, and quality
management requirements relevant to the workplace in which assessment is carried
out.

Practical exercises should be used for assessment wherever possible.
Outcomes and evidence requirements
Outcome 1
Interpret technical specifications for test equipment and explain the principles of equipment
operation.
Evidence requirements
1.1
The technical specification for a minimum of three different types of test
equipment is interpreted correctly and an explanation verifies understanding of
the operations and functions of the selected test equipment.
Range
1.2

This CMR can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.
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.
