URN: SEMMME229
Business Sectors (Suites): Mechanical Manufacturing Engineering Suite 2
Developed by: Enginuity
Approved: 2026

Overview

This standard identifies the competences you need to assemble electrical or electronic components to mechanical equipment, in accordance with approved procedures. You will be required to check that specified components are available and fit for purpose, to obtain all relevant and current documentation, to obtain the tools and equipment required for the assembly operations and to check that they are in a safe and usable condition. In carrying out the assembly operations, you will be required to follow company procedures and specified assembly techniques, in order to fit the electrical or electronic components to the mechanical assembly.

The assembly activities will also include making all necessary checks and adjustments, to ensure that the electrical or electronic components are correctly orientated, positioned and secured correctly. You must also check that any cables and wires are routed correctly and are tidy in appearance, and that connections are mechanically sound and checked for electrical continuity.

Your responsibilities will require you to comply with organisational policy and procedures for the assembly activities undertaken, and to report any problems with the assembly activities, materials or equipment 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 own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will be sufficient to provide a good understanding of your work, and will provide an informed approach to applying electrical or electronic fitting and assembly techniques and procedures. You will have an understanding of the product being assembled and its application, and will know about the equipment, relevant components and joining techniques, in adequate depth to provide a sound basis for carrying out the activities to the required specification.

You will understand the safety precautions required when carrying out the assembly activities. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.

K8    the assembly and securing methods and procedures to be used, and the importance of adhering to these
K9    how the components are to be positioned, aligned and secured, and the tools and equipment that are used
K10    the importance of using the specified electrical or electronic components and securing devices for the assembly, and why you must not use substitutes
K11    the quality control procedures to be followed during the assembly operations
K12    how to conduct any necessary checks to ensure the accuracy, position, security, function, completeness and electrical continuity of the assembly
K13    how to detect assembly defects and what to do to rectify them
K14    how to check that the tools and equipment to be used are in a safe and serviceable condition
K15    the importance of ensuring that all tools are used correctly and within their permitted operating range
K16    the importance of ensuring all tools, equipment and components are accounted for and returned to their correct location on completion of the assembly activities
K17    the issues that can occur with the assembly operations, and what to do if they occur
K18    the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
