2 Definitions
Industry practice – safe and sound practices generally accepted by competent trade persons within the fabrication industry.
Jigs
– devices that hold the component or object to be worked on securely in a definite position for a fabrication operation, and provide suitable location enabling subsequent operations or finishing.
Job specifications
– instructions relevant to the safe completion of the specific task, such as technical specifications, assembly instructions, drawings, parts lists, standards, codes of practice, test and commissioning procedures, and verbal instructions.
Safety guidelines
– guidelines for the safe operation of machinery and tools, such as those listed in the references, as well as guidelines for specific machines in workshops.
Worksite procedures – operational procedures p ut in place by the candidate’s employer. These include site safety procedures, equipment operating procedures, job procedures, quality assurance, and procedures for the handling and disposal of materials and waste.
3 Range a All activities must demonstrate safe working practices. b All activities must be completed independently and reported within reasonable timeframes. c Jigs may either control components for assembly or welding operations. d Minimum of four components must be dimensionally controlled to within a maximum tolerance of 2mm for dimensions up to 1m, and 3mm for dimensions of over 1m. e Clamping restraints must be applied for at least two components within the jig. f Evidence of at least three unique projects is required.
Element 1

3.2 Completion of work is reported in accordance with worksite procedures.
Please note
Providers must be 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 accredited by NZQA 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.
