Special notes
1
The following apply to the performance of all elements of this unit standard:
a
All required equipment must be set up, started up, operated, and shut down in
accordance with company procedures.
b
All work practices must meet recognised codes of practice and documented
worksite health and safety procedures (where these exceed code) for personal,
product, and worksite health and safety, and must meet the obligations required
under the Health and Safety in Employment Act 1992.
c
All work practices must meet recognised codes of practice and documented
worksite environmental procedures (where these exceed code) for personal,
product, and worksite environmental matters, and must meet the obligations
required under the Resource Management Act 1991.
d

Definition
FRC – fibre reinforced composite, as used in this unit standard is a generic term that
encompasses GRP (glass reinforced plastic). FRC may be laminated from any
combination of fibres, cores and resins including polyester, vinylester and epoxy
resins.

Please note
Providers must be accredited by the Qualifications Authority, or an inter-institutional body
with delegated authority for quality assurance, before they can report credits from
assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by the Qualifications Authority before
they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP 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.
