Corrosion on Ex Equipment — When is it a Deficiency?
This article covers Corrosion on Ex Equipment — When is it a Deficiency?. Corrosion on Ex equipment is common in offshore and marine environments. This guide explains how to classify corrosion deficiencies — when corrosion is Category B, Category A, or Category X.
Key Requirements
This inspection topic is covered in depth in IEC 60079-17 and tested in CompEx Ex03 and Ex04 assessments. Understanding the correct approach to this inspection scenario is essential for safe hazardous area inspection practice.
EX Academy's 15 inspection simulations cover this and related inspection scenarios. Each simulation presents a real work order, equipment data, and inspection findings that require deficiency identification and classification — exactly as you will face in your CompEx assessment.
Classification Guide
When assessing this type of deficiency, always apply the fundamental question: does it compromise the protection mechanism? Use the Category X/A/B/C framework from IEC 60079-17 to make your classification decision and document your findings clearly.
