Explanatory notes
1References
Legislation and standards relevant to this unit standard include the Health and Safety in Employment Act 1992 and any subsequent amendments, and NZS/AS 1100.101:1992 Technical drawing – General principles.
2Definitions
Company quality control procedures – specific details on an engineering drawing covering: checked and approved signatures for the release and use of a drawing; version numbers; compatibility with a master drawing; date of issue stamps; as well asprocedures forthe copying; recording; filing; and modification of a drawing.
Job requirements – the worksite procedures for accurately identifying the componentry, materials, equipment and machine procedure for a specific product.
Pull-in – the geometrical performance of an assembled window stay.
Specifications – all aspects of a technical engineering drawing which detail the dimensions, tolerances, and design of the completed product.
3Assessment information
–All work practices must meet recognised codes of practice and documented worksite safety procedures (where these exceed the codes) for personal, product, and worksite safety), and must also meet the obligations required under current legislation.
–This unit standard is designed for people within manufacturing industries who are engaged in production processes and are required to use technical engineering drawings for checking product design, for setting production machinery such as presses, drills, drill presses, lathes, cut-off saws, die casting and Computer-Numerical Controlled (CNC) machines; and for checking the quality of the finished product. It covers the reading and interpretation of drawings using dimension, centre section, hidden and projection (extension) lines; diameter, radius internal diameter, outside diameter and symbols; 3rd angle projection, section and exploded views; product quality check dimension check boxes; countersunk, counterbore, and chamfer symbols; datum positions (dimensions); Scale 1:1,1:2, 2:1, and Not to Scale (NTS) orthographic projection, including hidden detail and singleplane sectional views. Drawings are limited to single components and may include assemblies.

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.
