Accreditation Evaluation of documentation and visit by NZQA and industry. Standard setting body (SSB) Competenz Accreditation and Moderation Action Plan (AMAP) reference 0173 This AMAP can be accessed at http://www.nzqa.govt.nz/framework/search/index.do. Special notes 1 Definitions Tipping refers to the fixing of a metallic tip to saw teeth. Worksite documentation refers to instructions to staff on policy and procedures (including the application of legislation to worksite situations), which are formally documented, and are available for reference at the worksite. Examples are standard operating procedures, specifications, manuals, and manufacturer’s information. For people already employed in the industry, the worksite referred to is their employer's. For other people, the worksite will be either a local worksite or a typical New Zealand worksite. For these learners, the Industry Training Organisation will ensure that the training given by accredited providers meets these standards. 2 Range New Zealand Qualifications Authority 2016 8337 version 3 Page 2 of 4 saws – circular, frame or band saws; evidence is required of one saw type and one tip type. 3 The following apply to the performance of all elements of this unit standard: a All work practices must meet recognised codes of practice and documented worksite health and safety and environmental procedures (where these exceed the code) for personal, product and worksite health and safety, and must meet the obligations required under current legislation, including the Health and Safety in Employment Act 1992, the Resource Management Act 1991, and their subsequent amendments. b All work practices must meet documented worksite operating procedures.

Elements and performance criteria Element 1 Manage hazards associated with tipping saws with stellite or high speed steel. Performance criteria 1.1 Hazards associated with tipping saws with stellite or high speed steel tips are identified and actions to be taken to isolate, minimise or eliminate the hazard are described in accordance with worksite documentation. Range 1.2 hot objects, moving equipment, grinding wheel disintegration, loose grinding wheel, exposure to grinding coolant. Safe work practices associated with tipping saws with stellite or high speed steel tips to saws are identified and used in accordance with company and legal requirements. Range practices may include but are not limited to – isolation procedures, lock outs, emergency stops, machine guarding, the wearing of appropriate safety equipment Element 2 Prepare saws for tipping. Performance criteria 2.1 Saw and work areas are cleaned of all foreign matter that could affect tipping operations. 2.2 Teeth are assessed for wear and damage, and teeth are re-profiled where indicated.

Range welding equipment, dial gauges, micrometer, calipers, tweezers, safety equipment, cleaning agent. 2.4 Saw is set up in the tipping machine in accordance with worksite documentation and/or manufacturer’s specifications. 2.5 Seats are ground to receive the length of the tip. 2.6 Teeth are deburred to meet worksite documentation. 2.7 Tips are selected for size and type to suit saw application. Element 3 Tip saw teeth. Performance criteria 3.1 Tips and seats are cleaned of all foreign matter that could affect tipping operations. 3.2 Tipping equipment is set up and operated in accordance with worksite documentation and/or manufacturer’s specifications. 3.3 Tips are welded so that they adhere to the tooth. 3.4 Heat affected area is annealed. 3.5 Slag is removed from welded area. 3.6 Each tip has sufficient material for side dressing to the required kerf. Element 4 Grind saw teeth to size. Performance criteria 4.1 New teeth are ground to the same size as the original teeth. 4.2 Teeth are side ground to required radial and tangential angles and company kerf requirements. 4.3 Grinding solutions are handled and stored in accordance with Material Safety Data Sheets (MSDS) and worksite documentation. New Zealand Qualifications Authority 2016 8337 version 3 Page 4 of 4 Please note Providers must be accredited by the Qualifications Authority, 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 accredited by the Qualifications Authority before they can register credits from assessment against unit standards. Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards. Accreditation 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.
