1.3 Factors that influence the selection of carpets for special end-uses are described in terms of carpet properties and performance.

Range properties – price, appearance retention, colour, flammability and burning, cleaning and maintenance, pile weight, pile type, backing requirements, chemical treatments and other special treatments, environmental, safety and hygiene considerations, energy efficiency, economic lifetime, depreciation; special end use – aircraft carpet, hospitals, computer and electronic equipment locations.

1.4 Characteristics of carpet as a floor covering are compared with other floor coverings in terms of performance and use.

Range other floor coverings – rugs, laminates, timber, tiles, modular carpets, engineered surfaces such as concrete and metal; characteristics – aesthetics, comfort (acoustic, thermal, walking), maintenance.

Outcome 2

Demonstrate knowledge of carpet performance.

Evidence requirements

2.1 Factors that influence carpet appearance retention are described in terms of constructional properties, the types of the appearance change and end-use situations.

Range constructional properties – fibre type, yarn construction, carpet construction, blends, backing properties; end-use situations – traffic density, location, cleaning methods, exposure to light, local soil type, wet areas; types of appearance change – colour change, soiling and staining, shading (or pile reversal), texture changes, pile thickness loss, fibre shedding, surface fuzzing and pilling, dimensional s stability. is i 2.2 Methods of stabilising carpet pile to enhance appearanced rd retention are described and compared. ar a dnd Range methods – chemical setting,na melt bonding, heat setting, anti- shading treatments.tast g st ngin 2.3 Factors that influence carpetit ndurabilityi r arei i describedr in terms of constructional properties and end-usen situations.u i p us xpx Range constructionalis i e propertiese – fibre type, yarn construction, carpet hconstruction,h blends, backing properties; T end-useT situations – traffic density, location, cleaning methods, exposure to light, local soil type, wet areas.

2.4 Treatments and additives used to enhance carpet performance are described in terms of their application and effect on performance.

Range insect resist, antistatic, flame resist, anti-soiling, stain resist, delustering, anti-shading, smoke retardant, anti-photobleaching.

2.5 Environmental factors influenced by carpets are described in terms of the benefits and disadvantages of the changes caused by carpets, and the ways in which carpets can be modified to enhance the changes.

Range factors – acoustic and thermal comfort, moisture buffering, electrostatic effects, insect infestation, indoor air quality; modifications – insect resist treatments, anti-static treatment, sanitising.

2.6 Tests which enable predictions of carpet performance to be made are described.

Range pile density, appearance retention, durability, colour fastness, tuft bind, soiling propensity, shading propensity, backing delamination strength.

2.7 Carpet constructional parameters are calculated according to industry standard methods.

Range pile density, pile weight, stitch rate, gauge, pile height.

2.8 Contemporary carpet grading and labelling schemes are described and compared in terms of their assessment methods, and relevance in use.

Range grading schemes – Fernmark scheme manufacturer’s ratings, British Standards Association system, International Wool Secretariat grading, Canesis Network Ltd ratings; labelling – fibre labels, special treatment labels.

Consent and Moderation Requirements (CMR) reference 0030 This AMAP can be accessed at http://www.nzqa.govt.nz/framework/search/index.do.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards.

Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards.

Consent requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
