Application
This unit of competency describes the outcomes required to visually stress grade Australian white cypress (Callitris glaucophylla) by assessing material for strength against set classifications as detailed in Section 3 of the Australian Standard AS2858 as a minimum standard.
The unit applies to those who visually stress-grade cypress in a forest products factory setting.
No licensing, legislative, regulatory, or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENTS | PERFORMANCE CRITERIA |
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 for visually stress-grading cypress and clarify with appropriate personnel. 1.2 Identify grading requirements in line with site procedures, standards and specifications. 1.3 Select materials, hardware items, tools and equipment appropriate to work order and check for operational effectiveness. 1.4 Position cypress to be graded to provide appropriate access and facilitate efficient workflow. 1.5 Establish and maintain communication with others at site to ensure safety. |
2. Evaluate cypress | 2.1 Identify species and check status of seasoning. 2.2 Accurately record size and tolerance measurements in line with site requirements. 2.3 Establish characteristics and evaluate in line with standards and product specifications. 2.4 Measure moisture content and evaluate against standards and seasoning requirements. |
3. Grade cypress | 3.1 Visually stress grade cypress based on standards for the required structural grade. 3.2 Diagnose and check characteristics with the greatest limiting effect on the grade. 3.3 Assess the appearance, and mark, segregate and dispose of, in line with site procedures and environmental requirements 3.4 Record and report results of grading in line with workplace procedures. |
Evidence of Performance
A person demonstrating competency in this unit must satisfy all of the elements, performance criteria and foundation skills of this unit.

follow organisational policies and procedures, standards and codes of practice for visually stress grading cypress
record and report grading activity.
Evidence of Knowledge
A person competent in this unit must be able to demonstrate knowledge of:
applicable regulations, standards, codes of practice and established safe practices for visually stress-grading cypress, including Australian Standard AS2858
organisational and site standards, policies and procedures for visually stress-grading cypress
environmental risks and hazards associated with grading timber
grading markings and standards
characteristics and properties of cypress
visual stress-grading techniques and methods
structural grade: structural conformity of the timber, consistency of the structural quality, defects which may weaken strength, including knots, shakes and short grain
appearance of contamination, surface characteristics and grain pattern
criteria for recycling and re-using sub-standard material
recycling timber with inappropriate defects or contamination
re-using timber with inappropriate defects or contamination
redirecting timber with inappropriate defects or contamination for energy recovery
storage systems and labelling procedures
established communication channels and protocols
procedures for recording and reporting workplace information.
Assessment Conditions
The following resources must be made available:
cypress for visual stress grading
work order, workplace requirements and site standards for visually stress grading cypress
vernier callipers
moisture meters (resistance and/or capacitance)
tapes
marking implements
personal protective equipment required for visually stress grading cypress
relevant personnel for the purposes of communicating information.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessor requirements
Assessors must:
hold the appropriate assessor competency standards as outlined in regulations; and
be able to demonstrate vocational competencies at least to the level being assessed; and
be able to demonstrate how they are continuing to develop their VET knowledge and skills as well as maintaining their industry currency and assessor competence.
