Explanatory note

None.

Outcomes and evidence requirements

Outcome 1

Analyse chemicals used for, and objectives of, leather finishing.

Evidence requirements

1.1Characteristics of leather finishing materials are analysed in terms of their chemical nature and physical properties and their contributions to leather finishing requirements.

Rangeevidence is required of pigments, film formers, and one of the following – dyes, finish modifiers, fillers, penetrators, cross linking agents.

1.2Dry work treatments for the production of waterproof resistant or impregnated leathers are analysed in terms of processing procedure and reagents used.

1.3Objectives of finishing are explained in terms of required attributes in final leather.

Rangeevidence is required of four of the following – fashion aesthetics, colour, gloss, feel, defect concealment, flexibility, rubfastness, colour fastness, wear resistance.

Outcome 2

Analyse leather finishing methods and equipment.

Evidence requirements

2.1Leather finishing applications are analysed in terms of the composition of each finish coat and its purpose.

2.2Leather finishing application methods are analysed in terms of the procedures used.

Rangeevidence is required of two, which may include but are not limited to– padding, spraying, roller coating, foil laminating.

2.3Leather finishing application machines are analysed in terms of their key constituent parts.

Rangeevidence is required of one of the following – padding machine, sprayer, roller coater.

Outcome 3

Evaluate leather finishing performance testing.

Evidence requirements

3.1Leather finishing performance characteristics are evaluated in terms of testing method and how test criteria define suitability for purpose.

Rangeevidence is required of four, which may include but are not limited to – light fastness, rub fastness, scuff resistance, finish adhesion, flexibility, heat resistance, water penetration.

Please note

Providers must be granted consent to assess against standards (accredited) by NZQA, 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.

Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMRs). The CMR 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.
