Range tolerances may include but are not limited to – temperature, pressures, flow rates, production rate, pH, proportions.
2.3 All operations are safely completed and workplace and equipment are cleaned in accordance with operating manuals and company procedures.
Range operations – inventory, start-up, shut-down, load-out.
2.4 Binders are handled and stored to avoid product deterioration in accordance with operating manuals and technical data sheets.
Range stirring, heating;
examples of deterioration – polymer agglomeration, emulsion settlement.
2.5 Materials and product sampling and testing are carried out and documented in accordance with the sampling and testing plan.
Range base bitumen, emulsion, polymer, finished binder.
2.6 Binder product meets target properties specified in contract quality plan.
Range evidence is required of – understanding test results, conformance, non-conformance, corrective action.
2.7 All binder documentation is completed in accordance with customer requirements, specifications, contract quality plans, and company procedures.
2.8 Binder is loaded in accordance with operating manual and company procedures, and documentation is completed in accordance with legislation.
Range tank space and contents must be checked prior to load-out.
Outcome 3
Manage environmental protection and plant maintenance at a bituminous binder plant.
Evidence requirements
3.1 Consents for the plant are accessed to confirm requirements for environmental protection in accordance with company procedures.
3.2 Environmental protection is planned and emissions are controlled in accordance with consent requirements and operating manuals.
Range emissions – noise, dust, odour, fumes, steam, run-off.

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.
