This unit standard is intended for, but is not limited to, workplace assessment. While
all performance criteria 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. Any queries can be directed to the NZ Motor Industry
Training Organisation (Incorporated) (MITO).

Definitions
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.
Artificial lift equipment may include but is not limited to:
pumps – jet, electric submersible, beam, plunger lift, compressed gas lift;
testing and monitoring equipment – sonarlogs, dynameters, dipping equipment, tanks
and treaters, pressure gauges, temperature gauges, flow meters, centrifuges, chart
recorders;
prime movers – electrical motors, diesel and gas engines;
controllers – electrical, pneumatic, mechanical chemical.

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.
