Elements and Performance Criteria

1. Identify the categories and levels of verification for reference standards
   • The categories of reference standards that the organisation is authorised to verify are identified.
   • The classes of reference standards required to verify a range of standards are identified.
   • Tolerances for a range of reference standards are identified.
   • Tolerances for a range of reference standards are described.
2. Maintain suitable environmental conditions to facilitate verification of reference standards
   • Reference standard details are recorded in accordance with organisational guidelines.
   • Sources of possible operational procedures errors in the verification of reference standards are identified.
   • Required atmospheric conditions for the verification of a range of reference standards are applied.
   • Environmental conditions are assessed to determine whether a verification can be conducted.
3. Examine the design and required markings for a range of reference standards
   • The identification marking required for reference standards is located and explained.
   • Design features of a range of reference standards are correctly identified and applied.
   • The function of major components for a range of reference standards is described and applied.
   • The fundamental features of a range of reference standards are identified and explained.
4. Perform verification of reference standards
   • A variety of reference standards are verified.
   • Uncertainty and tolerances for reference standards are applied.
   • Results of verification are documented and certificate of verification is issued in accordance with organisational procedures, legislation and policies.

Required Skills

Required skills

Look for evidence that confirms skills in researching and identifying suitable reference standards for verification within standards hierarchy accessing reference manuals to gain appropriate information concerning tolerances for reference standards completing the organisations information tracking documentation identifying operational errors relevant to the verification locating identification marks on reference standards researching design features on a range of reference standards completing verification work sheets completing and issuing certificates of verification

Required knowledge

Look for evidence that confirms knowledge of relevant categories of reference standards for which the organisation is authorised to verify a range of classes for reference standards appropriate tolerance for a range of reference standards current status of clients reference standards atmospheric factors required for verifying a range of reference standards remedial action for atmospheric deficiencies environmental factors that may adversely influence the integrity of the reference standards remedial action for a range of environmental deficiencies requirements for identification marking on reference standards the purpose of design specifications the purpose of the major components and functions of reference standards the fundamental features of reference standards the process for maintaining integrity of results including calculation the reference material for uncertainty and maximum permissible errors for a variety of reference standards the process for producing certificates of verification in accordance with verifying authority status

Evidence Required

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 verify reference standards Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
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 that is the candidate is not in productive work then an appropriate simulation 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 The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with verifying reference standards or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

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.
Reference standards	Mass, volume, density, area, length, master meters, temperature
Operating procedures	Manufacturers' specifications, industry guidelines, Australian standards, legislation, organisational procedures and guidelines
Legislation and policies	Enabling legislation, organisational procedures and guidelines Workplace health and safety legislation including storage and transportation of test equipment, handling of test equipment, handling of hazardous materials, safety clothing, manual handling techniques, site/premises conditions
Documentation	Fees, verification work sheets, certificate of verification
