Definitions
Operating window is the range of each of the process control parameters which
achieves product quality and production objectives in accordance with enterprise
requirements.
Production trial means trialling of products, tooling, material grades, or processing
equipment.
5
For the purposes of assessment, candidates are expected to employ their technical
expertise to achieve the product quality and production objectives of the trial.
Elements and performance criteria
Element 1
Review production trial results.
Performance criteria
1.1
Trial objectives are confirmed as a basis for comparison, prior to review of
results.
Range
trial objectives – preliminary product specifications (physical
properties, size, weight, appearance), production requirements
(output, rejects, yield, practical operating window).
1.2
Trial product quality results are reviewed and compared with trial objectives to
identify variations.
1.3
Trial production results are reviewed and compared with trial objectives to
identify variations.
Element 2
Analyse production trial results and make corrections for a future trial.
Performance criteria
2.1
Trial results are analysed to establish priorities for the correction of parameters
which are outside specifications.
Range
2.2
Changes are recommended to achieve product quality and production
requirements.
Range
2.3
trial results – product quality results, production results.
changes – product design and specifications, mould and/or tooling
design and construction, material grade, machine configuration or
specification, production specifications, processing parameters.
Changes are made in accordance with enterprise procedure to achieve the
required product quality and production requirements.

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.
