Explanatory notes
1
This unit standard can be assessed against off job.
2
This unit standard is recommended for candidates already familiar with standard
composite laminating and vacuum techniques.

Definitions
Resin infusion – low pressure (less than 0.5 bar) vacuum resin transfer moulding,
including RTM light.
Resin injection – injection resin transfer at pressure greater than 0.5 bar.
RTM light – low pressure closed moulding resin transfer technique that uses a semi
rigid matched pair of moulds clamped closed by a perimeter flange. Cavity vacuum
is typically less than 0.5 bar.
Outcomes and evidence requirements

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA, 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 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.
Consent 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.
