Overview

This standard identifies the competencies you need to carry out material coating operations by electrophoretic or autophoretic methods, in accordance with approved procedures. You will be expected to confirm with the authorised person, such as your immediate supervisor, that the equipment is ready for the coating operations to be performed and that all the required components/materials and consumables are available. You will be required to operate the electrophoretic or autophoretic coating equipment, in line with safe working practices and approved procedures, continuously monitoring the coating operations and where necessary, making minor adjustments or seeking help from the authorised person to make the required adjustments, in order to ensure that the work output is to the required quality. Meeting production targets will be an important issue and your production records must show consistent and satisfactory performance. Your responsibilities will require you to comply with organisational policy and procedures for the electrophoretic or autophoretic coating activities undertaken, and to report any problems with the coating activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, with a minimum of supervision, taking personal responsibility for your actions and for the quality of the work that you carry out. Your underpinning knowledge will be sufficient to provide a sound basis for your work and will enable you to adopt an informed approach to applying electrophoretic or autophoretic coating procedures. You will have an understanding of the electrophoretic or autophoretic coating process and its application and will know about the equipment, materials and consumables in adequate depth to provide a sound background for carrying out the activities, recognising and reporting coating defects and ensuring that completed components are to the required specification. You will understand the safety precautions required when working with electrophoretic or autophoretic coating equipment and solutions. You will be required to demonstrate safe working practices throughout. You will also understand your responsibilities for safety and the environment and the importance of taking the necessary safeguards to protect yourself and others in the workplace.

Performance criteria

You must be able to:

1. work safely at all times, complying with health and safety legislation,  regulations, directives and other relevant guidelines 2. follow work instructions and specifications 3. ensure the material surfaces to be treated are prepared for the finishing operations 4. check that the finishing equipment and treatment solutions are set up and maintained at satisfactory operating conditions and levels 5. carry out the treatment process following operating procedures and to meet the component specification 6. ensure that the treated workpiece achieves the required characteristics and meets the finishing specification 7. deal promptly and effectively with problems within your control and report those that cannot be solved 8. ensure that work records are completed, stored securely and available to others, as per organisational requirements 9. leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements

Knowledge and Understanding

You need to know and understand:

1. the specific safety precautions to be taken whilst carrying out the  activities (including any specific legislation, regulations or codes of practice relating to the activities, equipment or materials) 2. the health and safety requirements of the work area  and the activities, and the responsibility these requirements place on you 3. the hazards associated with  the activities, and how to minimise them and reduce risks 4. the personal protective equipment and clothing (PPE) to be worn during the activities 5. how to obtain and interpret the production documentation required during the coating activity 6. the basic principles of the operation of electro orautophoretic coating equipment 7. the visual checks to be made on components prior to coating 8. the pre-treatments carried out on components prior to coating 9. the methods used to hold and secure components during the coating process 10. the importance of monitoring equipment settings and process solutions during the electrophoretic or autophoretic coating process 11. how to make additions to process solutions 12. the types of adjustment that can be made to equipment settings to maintain component quality 13. how to identify electrophoretic or autophoretic coating process faults (including missed coating, bridging, excessive coating and dull finish) 14. the basic quality checks to be carried out on electrophoretic or autophoretic coated components 15. how to safely remove contaminants from coating solutions (including the checking and maintenance of filters) 16. the procedure for the safe disposal of waste materials 17. how to pack and store finished components to avoid damage 18. the importance of keeping the processing plant and equipment clean 19. the importance of completing the production documentation throughout the electrophoretic or autophoretic coating process 20. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve 21. how to access, use and maintain information to comply with organisational requirements and legislation
