Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Sound measuring equipment
Sound measuring equipment may include:
microphones
cables/connectors
meters
recorders
analysers/comper and software
Set-up and measurement techniques
Set-up and measurement techniques may include:
microphone positioning
meter time constants
frequency filter settings
Purpose for sound measurements
Purposes for sound measurements may include:
simple sound level or spectrum
limited or full frequency band
standards to be met
impulsive or consistant noise
Vibration
Vibration refers to continuous or sporadic vibration whether or not associated with noise and also includes mechanical shock
Vibration and shock measuring equipment
Vibration and shock measuring equipment may include:
accelerometer
impedance heads
cables
mounting media
calibrators
preamplifier
meters
filters
recorders
analysers/computer and software
Appropriate technical and professional assistance
Appropriate technical and professional assistance may include:
technical support and advice relating to elements which have intrinsic dangers, such as:
high pressure
energised fluid vessels
high temperatures and heat energy capacity
wiring with high current control voltages above extra low voltage
professional support for technologies, such as:
specialist electric motor drives and controllers
specialist materials, plastics, metal alloys and nano materials
special processes, foundry, alloy welding, heat treatment, sealing and fastening
WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements
Standards and codes
Standards and codes refer to all relevant Australian and International standards and codes applicable to a particular noise and vibration measurement and analysis task
Systems thinking

Systems thinking refers to the conduct of engineering work in a manner that demonstrates knowledge of how the interaction of different technical systems on equipment, machinery or structures, as well as the skills and techniques of personnel, combine to perform or support engineering-related operations, processes or projects. It embraces determining or establishing how the function of each technical system or component, as well as the skills and techniques of personnel, effects or potentially may effect, outcomes. Systems should be interpreted broadly within the context of the organisation and depending on the project or operation can include equipment, related facilities, material, software, internal services and personnel, and other organisations in the value chain
Continuous improvement
Continuous improvement implementation may relate to plant, products, processes, systems or services, including design, development, implementation or manufacture, commissioning, operation or delivery and maintenance.
Improvement processes may include techniques, such as:
balanced scorecard
current and future state mapping
measuring performance against benchmarks
process improvement, problem solving and decision making
data management, generation, recording, analysing, storing and use of software
training for improvement systems participation
technical training
Constraints and contingencies
Constraints and contingencies may be:
financial
organisational, procedural or cultural
physical constraints, such as limits to resources, limits to site access or logistical limitations

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to measure and analyse noise and vibration and make recommendations for mitigation and protection.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
determine compliance with WHS and regulatory requirements, and risk management with particular emphasis on automation safety
review physics of sound and vibration, effects of noise, vibration and shock on humans, measuring equipment and mitigation measures
identify noise and vibration, noise dose and vibration exposure limits
select appropriate measuring equipment for measuring task
calibrate, site and set up equipment
correctly measure and record noise and vibration
analyse and interpret measurement results
relate data to plant and equipment performance
recommend noise and vibration elimination, mitigation and protection measures
investigate sustainability implications
report and document results and recommendations
apply systems thinking, continuous improvement problem solving and constraint and contingency management.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
