Competenz SSB Code 101571 New Zealand Qualifications Authority 2016 NZQA registered unit standard 5 695 version 7 Page 2 of 4 Definitions Preventative maintenance refers to the care and servicing of equipment and machinery. This may include periodic checks and inspections, testing, measurements, adjustments, or parts replacement as required in accordance with worksite policies and procedures for the purpose of preventing faults or failures and to maintain production requirements. Worksite policies and procedures refer to documented policies and to documented or other directions provided to staff. These include, but are not limited to, ways of managing health and safety, environmental considerations, quality, and production, and must conform to legislation. Examples include standard operating procedures, company health and safety plans, on-site briefings, and supervisor’s instructions. Outcomes and evidence requirements Outcome 1 Explain fundamentals of bonding and bonding agents. Evidence requirements 1.1 Adhesives used in wood panels manufacturing are identified in terms of their applications. Range 1.2 may include but are not limited to – urea formaldehyde, melaminefortified urea resins, isocyanate resins, phenolic resins, resorcinol adhesives, tannin. The purpose of introducing additives to synthetic resins is explained in terms of the additives’ effect on curing time and pot life. Range additives may include but are not limited to – curing agents, hardeners, buffers. 1.3 The chemical reaction that is heat-activated in the press is described in accordance with the reference text. 1.4 The consequences of non-conformance with worksite standards are described in accordance with worksite policies and procedures. 1.5 Physical factors affecting the bonding of wood are explained in accordance with the reference text. Range 1.6 may include but are not limited to – wood moisture content, glue type and mix, pressing time and temperature, wood fibre. Safety data sheets are explained in terms of their location, chemical content and potential hazards. Outcome 2 Competenz SSB Code 101571 New Zealand Qualifications Authority 2016 NZQA registered unit standard 695 version 7 Page 3 of 4 Monitor bonding agent mixing. Range bonding agents may include but are not limited to – curing agents, hardeners, waxes, scavengers. Evidence requirements 2.1 Recipes are selected for given products in accordance with worksite policies and procedures. 2.2 Mixing operations are monitored to ensure the prescribed ratios are being maintained in accordance with worksite policies and procedures. Outcome 3 Apply bonding agents. Range equipment may include but is not limited to – glue blender and/or spreader and/or injection nozzles, and/or glue curtain. Evidence requirements 3.1 Adhesives are applied to wood furnish in accordance with worksite policies and procedures. 3.2 Hazards associated with bonding and bonding agents are identified and managed in accordance with worksite policies and procedures. 3.3 Adhesive application rate is matched to wood flow. 3.4 Equipment is set up, started up, operated, and shut down in accordance with worksite policies and procedures. 3.5 Operating faults and malfunctions are identified, and corrective action is taken, in accordance with worksite policies and procedures. Range 3.6 out-of-specification applications, incorrect formulations. Preventative maintenance and cleaning requirements are explained and applied in accordance with worksite policies and procedures. Outcome 4 Monitor application of bonding agents. Evidence requirements 4.1 Monitoring and interpretation of feedback information, and adjustment of control parameters, enable process requirements, plant performance, and bonding to be maintained in accordance with worksite policies and procedures.
