Explanatory notes
1Performance of the outcomes of this unit standard must comply with relevant site requirements, manufacturer’s recommendations, and the following legislation:
Health and Safety at Work Act 2015;Resource Management Act 1991.
2This unit standard is intended for, but is not limited to, workplace assessment. While all evidence requirements must be met, it is noted that all range statements within this unit standard are indicative and dependent on enterprise and site specific equipment, procedures, and practices.
3Definitions
Primary data refers to first analysis results.
Site requirements mean the site specific documented methods for performing work activities and include health, safety, environmental, and quality management requirements. They may refer to manuals, codes of practice, or policy statements.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA, 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.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMRs). The CMR 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.
