FOREST PRODUCE INSPECTION
Apply knowledge of wood technology for the inspection of wood produce
planned review date: December 2004
purpose: People credited with this unit standard are able to: identify solid wood characteristics; verify characteristics of veneered and reconstituted wood products; and verify characteristics of machined and remanufactured timber.
entry information: Open.
accreditation option: Evaluation of documentation and visit by NZQA and industry.
moderation option: A centrally established and directed national moderation system has been set up by Forest Industries Training.
special notes: 1 The term forest produce, in this unit standard, includes but is not limited to - roundwood, logs, sawn timber, packaging and manufactured wood items.
2 International agreements relating to this unit standard include the Convention on International Trade in Endangered Species of Wild Fauna and Flora, (CITES).
Elements and Performance Criteria
Identify solid wood characteristics.
1.1 The mechanisms of tree growth and function are described in terms of tree parts, growth process, and wood type.
Range: tree parts - crown, trunk, roots, pith, bark, cambium, apical mirestems;
growth process - photosynthesis, cell division, growth increments;
wood type - heartwood, softwood, corewood, earlywood, latewood.
1.2 Natural growth characteristics are identified in sawn timber and logs.
Range: knots, cone holes, resin and bark pockets, pith, early and late wood, compression and tension wood, hardwood and softwood cell structure, shakes, occlusion.
1.3 Abnormal growth characteristics are identified in sawn timber and logs.
Range: burrs, cankers, abnormal growth caused by mechanical and animal damage.
1.4 Characteristics of sawn timber are identified for quarter-sawn, flat-sawn, and tangentially-sawn timber.
Range: figure, grain types.
1.5 The susceptibility of solid wood produce to attack by pests and diseases is identified in relation to species; durability; wood structure; chemical and moisture content; and tree part.
Range: tree part - sapwood or heartwood, bark and cambium.
1.6 Common New Zealand grown species are identified from representative samples, without the use of reference data.
Range: Rimu, Kauri, Kahikatea, Silver and Red beeches, Douglas fir, Macrocarpa, Larch, Cypress, Eucalyptus, Pinus radiata, nigra and pondarosa.
1.7 Less common New Zealand grown species are identified from reference data.
Range: Black Walnut, Australian Blackwood, Matai, Totara, Tawa.
1.8 Prohibited export species as defined by the CITES schedule are identified from reference data, and Department of Conservation is informed of any breach of the Convention.
1.9 The interpretation and use of product descriptions facilitate the identification and verification of solid wood produce to the phytosanitary requirements of the importing country.
Verify characteristics of veneered and reconstituted wood products.
2.1 Reconstituted wood products are identified from representative samples.
Range: medium density fibreboard, hardboard, insulating board, particle board, triboard, strandboard.
2.2 Veneer and plywood products are identified from representative samples, in both their laminated and unlaminated forms.
2.3 The susceptibility of veneered and reconstituted wood products to attack by pests and diseases is identified in terms of manufacturing processes, product additives, and longevity.
2.4 The interpretation and use of product descriptions facilitate the identification and verification of veneered and reconstituted wood products to the phytosanitary requirements of the importing country.
Verify characteristics of machined and remanufactured timber.
3.1 Machined timber profiles are identified from representative samples.
Range: dressed four sides; bevel back and rusticated weatherboards; scotia, architrave and quad mouldings; tongue and groove flooring and panelling; shiplap panelling.
3.2 Machining defects are identified from representative samples.
Range: raised grain, torn grain, sniping, feather edging, machine skip.
3.3 Remanufactured timber forms are identified from representative samples.
Range: green and dry finger-jointed timber, laminated timber, edge-glued timber, laminated veneer lumber.
3.4 The interpretation and use of product descriptions facilitate the identification and verification of machined and remanufactured timber to phytosanitary requirements of the importing country.

Please Note: Providers must be accredited by the Qualifications Authority before they can offer programmes of education and training assessed against unit standards.
Accredited providers assessing against unit standards must engage with the moderation system that applies to those unit standards. [Please refer to relevant Plan ref: 0173]
