     MOE refers to the Modulus of Elasticity that is a measure of stiffness.

     MOR refers to the Modulus of Rupture that is a measure of bending strength.

     Worksite documentation refers to instructions to staff on policy and procedures

    (including the application of legislation to worksite situations), which are formally

    documented, and are available for reference at the worksite. Examples are standard

    operating procedures, specifications, manuals, and manufacturer's information.

    2 All activities must be completed within a timeframe agreed between the candidate

    and assessor.

    4 The following apply to the performance of all elements of this unit standard:

     a All work practices must meet recognised codes of practice and documented

    worksite health and safety and environmental procedures (where these exceed

    the code) for personal, product and worksite health and safety, and must meet

    the obligations required under current legislation, including the Hazardous

    Substances and New Organisms Act 1996, the Health and Safety in

    Employment Act 1992, the Resource Management Act 1991, and their

    subsequent amendments.

     b All work practices must meet documented worksite operating procedures. This

    includes the recording (by electronic or non-electronic means) of activities,

    events, and decisions.

     c All evidence of communications gathered in relation to this unit standard must

    be in accordance with worksite procedures for content, recipient, timing and

    method.

Please note

    Providers must be accredited by the Qualifications Authority, 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 the Qualifications Authority 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.
