List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Prepare for stress-grading | 1.1 Review work order and where required check with appropriate personnel. 1.2 Select appropriate personal protective equipment and check for operational effectiveness. 1.3 Obtain type and quantity of timber for stress grading from storage location. 1.4 Plan stress-grading process in line with work order. |
2. Set up equipment | 2.1 Use equipment in line with organisational safety procedures, manufacturer’s instructions and environmental protection practices. 2.2 Complete pre start-up checks on equipment to ensure operational effectiveness. 2.3 Set up spray guns or branding rolls for use in line with work order. 2.4 Complete calibration process using verification boards and set grade thresholds in line with organisational procedures. |
3. Stress grade timber | 3.1 Complete automatic grading process, monitor and adjust material flow to machine. 3.2 Monitor machinery to ensure consistent grade marking and board appearance in line with industry standards. 3.3 Withdraw samples for independent testing and prepare according to testing procedures. |
4. Complete operator maintenance | 4.1 Follow organisational safety procedures to lock out equipment. 4.2 Check and clean photo-electric cells and reflectors in line with environmental protection practices. 4.3 Check and refill spray guns or branding rolls. 4.4 Adjust and maintain mechanical stress grade rollers, auto-feed and load pressure in line with manufacturer’s recommendations. 4.5 Keep stress-grading area clear of dust and debris in line with organisational safety procedures. 4.6 Record and report production outcomes, equipment faults and maintenance requirements to appropriate personnel. |
A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit. If a specific volume or frequency is not stated below, then evidence must be provided that the following requirements have been performed on at least one occasion:
