Definitions
I-value – the moment of inertia is a numerical value which refers to the deflection
strength of an aluminium extrusion in relation to the wind zone and wind loading. It is
used to calculate the effect of wind load on the strength, length and spacing, in the
construction of a window, of its structural members, for example mullions and
transoms.
WANZ WIS – the Window Association of NZ (Inc.) Window Installation System
developed for the installation of aluminium windows and doors into the external walls
of buildings.

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.
