Explanatory notes
Definition
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.
Outcomes and evidence requirements
Outcome 1
Define properties of adhesives used in wood product manufacturing.
Evidence requirements
1.1Definition identifies categories of adhesives used in wood product manufacturing and aligns them with products.
Rangecategories may include but are not limited to – water resistant, moisture resistant, interior.
1.2Definition identifies the chemical structure of key adhesives and describes how this impacts on the adhesives’ effectiveness and limitations of use.
Rangekey adhesives may include but are not limited to – formaldehyde, polyvinyl acetate, urethane.
1.3Definition identifies the properties required of bonds for products in wood product manufacturing and describes how these are achieved.
1.4Definition identifies the factors that influence the effectiveness of adhesives and describes how these factors are controlled.
Outcome 2
Define storage and handling requirements of adhesives used in wood product manufacturing.
Evidence requirements
2.1Definition describes the identification, classification, signage and handling requirements of adhesive chemicals used in wood product manufacturing.
2.2Definition describes the storage and disposal requirements, for various categories of adhesive used in wood product manufacturing, and identifies how these requirements are met for specific adhesives on a specified wood product manufacturing site.
Rangecategories may include but are not limited to – water resistant, moisture resistant, interior.
2.3Definition includes procedures and protective equipment required for the safe handling of adhesive chemicals in wood product manufacturing.
2.4Definition identifies emergency procedures and treatment for adhesive spillage on a wood product manufacturing site.
Outcome 3
Explain adhesive failures in wood product manufacturing.
Evidence requirements
3.1Explanation identifies six causes for adhesive failure in wood product manufacturing.
3.2Explanation describes the physical characteristics that indicate the likely causes of adhesive failure in wood products.
3.3Explanation describes processes for determining adhesive failure in accordance with worksite documentation.
3.4Explanation includes a report on samples of given products with adhesive failures where the causes of failure are determined in accordance with worksite documentation.

Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR 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.
