Credits
Purpose
4
This unit standard is for experienced people wishing to develop
their technical skills in leather manufacture.
People credited with this unit standard are able to: demonstrate
knowledge of measurement of hide and skin raw material
characteristics; analyse the measurements used for process
control in leather manufacturing; and analyse the
measurements used to define finished leather properties.

Outcomes and evidence requirements
Outcome 1
Demonstrate knowledge of the measurement of hide and skin raw material characteristics.
Evidence requirements
1.1
Measurements and units used to define the condition and characteristics of
untanned hides and skins are explained in relation to specified raw materials.
Range
1.2
evidence is required of three of the following – weight, thickness,
area, moisture content, temperature, degree of preservation.
Instruments for measurement of raw hide and skin characteristics are outlined
in terms of their principle components, operating principles and methods of use.
Range
evidence is required of two of the following – area measuring
machine, thickness gauge, moisture meter, dipslides.
Outcome 2
Analyse the measurements used for process control in leather manufacturing.

Range
3.2
evidence is required of three measurements for each of three of
the following – upper, clothing, chamois, sole, woolskin, belt,
upholstery.
Instruments for measurement of finished leather properties are evaluated in
terms of their principle components, operating principles and methods of use.
Range
evidence is required of three instruments, which may include but
are not limited to – colour computer, tensometer, lastometer, rub
tester, soxhlet apparatus, flexometer.

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.
