Definition
Industry practice – safe and sound trade practice generally accepted by competent
persons within the mechanical engineering industry.
Worksite procedures – operational procedures put in place by the candidate’s
employer. These include site safety procedures, equipment operating procedures,
job procedures, quality assurance, and procedures for handling and disposal of
materials and waste.

Assessment information
Complex engineering measuring equipment refers to any equipment capable of
measuring in two dimensions (2D) with a minimum of measurement uncertainty, and
which requires specialist knowledge in terms of its purpose and operation. It may
include but is not limited to – gear tooth verniers, bevel protractors, thread measuring
equipment, surface finish instruments, 2D optical comparators (profile projectors),
computer-controlled height gauges, sine bars, and sine tables, co-ordinate
measuring machines.
Evidence is required for the selection, use, and care of at least three items of
complex equipment.

Outcomes and evidence requirements
Outcome 1
Select complex engineering measuring equipment.
Evidence requirements
1.1
Measuring equipment is selected having regard to the quantity to be measured,
expected magnitude, and ability to meet required tolerances.
1.2
Measurement technique is planned and explained prior to commencing work.
1.3
Measuring equipment is inspected for damage and faults, and, where
necessary, remedial action is taken in accordance with worksite procedures and
industry practice.
Range
damage and faults include but are not limited to – deformation,
breakages, missing parts, cleanliness, expired calibration, wear,
corrosion.
Outcome 2
Use complex engineering measuring equipment.
Evidence requirements
2.1
Use of the measuring equipment achieves the required accuracy, and the
tolerance of the measurement is quoted.
2.2
Measurements are validated by re-measurement with the same or alternate
equipment.
2.3
Measuring equipment and objects to be measured are not damaged during
measurement.
2.4
Measurements are recorded in accordance with industry practice.
Range
number of decimal places, units, prefixes, symbols, accuracy.
Outcome 3
Care for complex engineering measuring equipment.
Evidence requirements
3.1
Measuring equipment is handled and stored in a manner that maintains its
integrity.

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 (CMRs). 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.
