Definitions
Company procedures – the documents and procedures that include company rules,
codes and practices; machine and equipment operating instructions; quality and
conformance checks; and health and safety requirements.
Non-standard aluminium joinery products – unique designs or ‘one-off’ products
characterised by unusual or non-standard angles and dimensions. They include –
windows (arch, bay, bow, faceted, raked, internal and external corners, double hung,
greenhouse), doors (arch, raked, internal/external in plan corners).
Unusual angles – any angles that are not 45 or 90 degrees, or those not common to
the company’s products.

The skills needed for making non-standard products include the ability to: interpret
architectural drawings and/or work from site measurements; use the appropriate
geometrical equipment to calculate and measure the unusual angles and
dimensions; work out a step-by-step process; and develop a layout or work to a
supplied template.

Skills specific to cutting non-standard products include the ability to: interpret the
cutting system for unusual angles; set cutting machinery and other specialised
equipment, such as jigs, to these angles in preparation for precision cutting; and
safely and accurately operate the cutting equipment, which can be made more
complex by the angle at which it is set. For example, standard safety machine locks
cannot be used, and the operator must be able to set the locks to other positions.

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
