Course Description
The CompEx Ex12 – Application Design Engineer course empowers Electrical, Instrumentation & Control professionals to take charge of Ex system design — not just installation. It focuses on designing, specifying, and verifying electrical and instrumentation systems for hazardous (explosive) areas, ensuring full compliance with IEC 60079-14 and global Ex standards.
What certificate will i receive?
Upon successful completion, participants will receive a CompEx Certificate of Core Competence – Ex12 Application Design Engineer, valid for 5 years, along with a CompEx ID card.
Advantage: Provides globally recognised proof of competence and compliance in Ex design.
What is the duration of the course?
The typical course duration is 5 days (full-time), including written assessments.
Guided learning time is approximately 30–35 hours.
Advantage: A compact yet intensive training programme designed to deliver maximum learning depth in minimal downtime.
What are the entry requirements?
A relevant technical qualification such as HNC/HND or equivalent in electrical, instrumentation, or process engineering.
Minimum 2 years of engineering experience in hazardous area design or operations (recommended).
A solid understanding of electrical design principles and familiarity with IEC 60079-14.Proficiency in technical English for reading, writing, and comprehension.
Benefit: Ensures learners possess the right background to fully engage with advanced Ex design and assessment principles.
What does the course cover?
The aim of this course is to provide the knowledge, understanding, and skills required to competently design and specify electrical systems for explosive atmospheres in accordance with international standards and best practice.
Theory Topics (Part A)
Legislation, regulations, and certification schemes (ATEX, DSEAR, IECEx, EN/IEC Ex)
Fundamentals of explosive atmospheres and hazardous area classification (gases, vapours, dusts)
Explosion protection concepts – Ex d, Ex e, Ex p, Ex ia, Ex ib, etc.
Interpretation of Ex equipment markings and certificates
Roles and responsibilities of designers, manufacturers, and installers
Design & Application Topics (Part B)
Design and selection of Ex electrical and instrumentation systems
Intrinsically Safe (IS) loop design and verification
Installation design including wiring, segregation, earthing, and cable routing
Assemblies and mixed protection conceptsStandards, normative references, and compliance documentation
Applied Design Exercises (Part C) Equipment evaluation for specific hazardous area scenariosIntrinsically safe loop design and calculations
Design case studies with group presentations and critiques
Benefit: Learners build both theoretical and practical competence, ready to apply Ex design principles directly in professional environments.
How is the course assessed?
Written Examinations: Four assessment papers covering Ex knowledge, equipment marking, standards, and design application (approx. 7 hours total).
- Core knowledge and regulations (closed book)
- Standards and design exercises (open book)
Design Exercises: Evaluation of real-world case studies and Ex design proposals.
Benefit: Comprehensive assessment ensures each participant demonstrates both theoretical understanding and design application competence.
