Outcomes and evidence requirements

Outcome 1

Demonstrate knowledge of the membrane separation process in a dairy processing operation.

Evidence requirement

1.1Cleaning and sanitation requirements and procedures for a membrane separation process are outlined in terms of organisational requirements.

1.2Components of membrane separation equipment are identified and explained in terms of the functions and basic operating principles.

Rangeevidence is required of three components.

1.3The effect of the quality, composition and physical characteristics of raw materials is identified and explained in terms of process outcomes.

1.4The membrane separation process is explained in terms of basic principles.

1.5The main membrane separation controls and quality control points are identified and outlined in terms of their effect on the quality of the product.

Rangecontrols and control points may include but are not limited to –procedures, operating parameters, equipment and instrumentation components, materials and services;

effects may include but are not limited to – physical quality, functional quality, microbiological quality, consistency of quality;

evidence is required of three controls and three effects.

1.6Critical control points (CCPs), if relevant, are explained in terms of key operating parameters, monitoring and operational checks.

Outcome 2

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 (CMR). 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.
