Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Work requirements may include:
material to be used
process required to complete work tasks
the required size of the units
number of IGUs required and holding area for completed items
IGUs are:
two sheets of glass that are separated by a spacer, sealed to form an airtight unit
Personal protective equipment includes:
that prescribed under legislation, regulations and enterprise practices and procedures, and may include:
gauntlets
gloves
safety glasses
hard hats
safety footwear
aprons
hearing protection
overalls
Workplace procedures include:
workplace procedures relating to the setting up and operation of IGU manufacturing machinery
machine manufacturer specifications and operational procedures
workplace procedures relating to the handling and movement of glass
work instructions, including job sheets, cutting lists, plans, drawings and designs
safety standards, including personal protective equipment, OHS regulations and enterprise requirements
Australian Standards:
AS 1288:2006 Glass in buildings - Selection and installation.
AS/NZS 2208:1996 Safety glazing materials in buildings
AS/NZS 4666:2000 Insulating glass units
AS/NZS 4667:2000 Quality requirements for cut-to-size and processed glass
Tools and equipment are to include:
cutting equipment (e.g. saws)
spacer preparation equipment (appropriate size)
sieve machine and desiccant equipment
primary seal equipment
secondary seal equipment
basic hand tools (e.g. screwdrivers and scrapers)
mechanical handling equipment
Materials are to include, but are not limited to:
customer requirements for glass (annealed, toughened or laminated)
corner keys for spacers
appropriate primary (polyisobutylene) and secondary sealant (polysulphide) and separation paper
Desiccant is:
a hygroscopic substance that induces or sustains a state of dryness (desiccation)

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
interpret work order/job instruction and locate and apply relevant information, including relevant glass and window rating systems to the operation of IGU manufacturing equipment
plan the conduct of IGU manufacturing operations
set up, operate and monitor IGU manufacturing equipment and the quality testing of IGU
apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
follow work instructions, operating procedures and inspection practices to:
minimise the risk of injury to self and others
prevent damage to goods, equipment and products
maintain required production output and product quality
as a minimum:
prepare, set up, manufacture and conduct the appropriate quality testing of five (5) differing IGU patterns to the capacity of the IGU machine
work effectively with others.
Context of and specific resources for assessment
The application of competency is to be assessed in the workplace or realistically simulated workplace.
Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints.
Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context.
Assessment is to comply with relevant regulatory or Australian Standard requirements.
The following resources should be made available:
insulated glass unit manufacturing equipment
workplace operating procedures
unprocessed materials
personal protective equipment
an appropriate work area.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the LMF02 Furnishing Industry Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency.
