Competenz has completed the review of the unit standards listed above that were registered in January 1995 and February 2000.
Date new versions published May 2004
New comments by date May 2008
Expiry date of new versions of the unit standards December 2009
Summary of review and consultation process
Two northern and southern pilot meetings involving Competenz, industry representatives, and accredited providers were convened in September 2002 to initially deliberate the concept of Maintenance and Diagnostics as it applies to Mechanical Engineering. Group discussion centred on the mix of unit standards available to candidates in the current level 4 and level 5 qualifications, in addition to future qualification options that may be applicable to this technologically dynamic industry.
The groups were also advised that a significant number of unit standards available to candidates in the level 4 and level 5 qualifications show an expiry date of December 2002. These unit standards were organised into logical sets and assigned to representatives on the basis of expertise and interest. Consequently, six expert sub-groups emerged from the initial pilot groups to manage the full review on a progressive basis. The full review was scheduled for completion October 2003, however, the extent and complexity of the review program has now seen the completion date taken to mid 2004.
This review report summarises the outcomes of the second expert sub-group.
It was recognised that some of these unit standards applied to other Competenz sectors and qualifications, including Machining and Toolmaking and Lifts and Escalators. On this basis, representatives from these sectors were invited to provide input as applicable.
Main changes resulting from the review
Part 1: Domain changes.
Fluid power is a generic term for the specialist areas of hydraulics and pneumatics. However, the two areas are fundamentally different in terms of function, system design, maintenance requirements, and industrial application. As such, the review group considered that hydraulics and pneumatics unit standards should be classified under separate domains, named as follows:
· Fluid Power - Hydraulics
· Fluid Power - Pneumatics
These domains were registered in October 2003, and all reviewed unit standards have been reclassified accordingly.
Part 2: Unit standard changes
The review process has resulted in the following changes to the unit standards.
· The term fluid has been removed from all titles. This term has been replaced by either hydraulic or pneumatic, depending on which arm of fluid power the unit standard is applicable to.
· The introduction of two new knowledge-based unit standards developed for hydraulics and pneumatics: 20611 and 20612. These two unit standards capture underpinning knowledge previously implicit in unit standards 17344 and 17345.
· Unit standards 17344 and 17345: Improved special notes to better indicate parameters for assessment.
· Unit standards 2722 and 2723: These unit standards required performance against both hydraulic and pneumatic systems, a situation not normally encountered in many work environments. Maintenance and safety performance outcomes are now captured against separate hydraulics and pneumatics unit standards of 20613, 20614, 20597, and 20598. It will be noted that while the credit value of unit standard 2723 was split proportionally between the two replacement unit standards, the credit value of 5 for unit standard 2722 was maintained for each of its replacement unit standards. The effective increase in credits more accurately reflects the extent of learning and performance required against each fluid power category.
· Unit standard 2724: Replaced by unit standard 20599, as the performance outcome is applicable to hydraulics only. Credit value of 4 has been retained as it reflects the extent of learning and performance required for this activity.
· Unit standard 2725: Improved special notes and performance criteria range items to better indicate parameters for assessment. Title changed to indicate that performance is under supervision.
· Unit standard 2726: Replaced by two new unit standards 20600 and 20601, and supported by the introduction of new unit standard 20602. All three unit standards focus on system design, with learning and performance progressing from an integrated system under supervision, to the design of a more specialised air distribution system.
· Unit standards 2727 and 2728: Reference to maintenance in titles changed to servicing, and a definition given for the latter in each unit standard. Improved special notes to better convey parameters for assessment. The same amendment rationale and improvements apply to unit standards 2731 and 2732.
· Unit standard 2729: Improved special notes, and the addition/expansion of performance criteria range items to better convey parameters for assessment.
· Unit standard 2730: Replaced by unit standard 20603, and supported by the introduction of 20604. These unit standards continue the learning and performance progression from unit standard 20602 alluded to above. Note that logic elements and servo positioning have been removed from unit standard 20603, thereby making it substantially different from its predecessor, unit standard 2730.
· Unit standard 2733: Improved special notes, and the addition/expansion of performance criteria range items.
· Unit standard 2734: Replaced by two new unit standards 20605 and 20606. Each unit standard represents a progression in fault diagnosis complexity and performance expectation, as reflected in the title, level, and special notes.
· Unit standard 2735: Replaced by unit standards 20607, 20608, and 20609
· Unit standard 2738: Replaced by unit standard 20610. Service/maintenance requirement in earlier unit standard removed. Applicable to hydraulic systems only.
· Unit standard 2736: Designated as expiring due to low usage. Unit standards 20603 and 20604, coupled with unit standard 5926 Demonstrate knowledge of programmable logic controllers (PLC), mayserve as a comparable performance outcome.
· Unit 2737: Designated as expiring due to low usage. A comparable performance outcome can be met via unit standard 11399, for which separate accreditation should be sought as appropriate.
Unit standards categorised as category C or D expire at the end of December 2005.
