Full title and description

St IECEx 03-4-2021 — IECEx Certified Service Facilities Scheme — Part 4: Inspection and maintenance (Rules of procedure). This publication defines the scheme rules and procedural requirements used by the IECEx System for certification of service companies that carry out inspection and maintenance activities on equipment and installations in explosive atmospheres (Ex).

Abstract

This document sets out the rules of procedure for the IECEx 03‑4 scheme (inspection and maintenance). It specifies how service companies are assessed and certified under the IECEx Certified Service Facilities Scheme for Ex inspection and maintenance services, including requirements for management systems, competence of personnel, assessment steps, on‑site audits, records, reporting and interfaces with Ex Certification Bodies (ExCBs). The aim is to provide consistent, internationally recognised assurance that inspection and maintenance of Ex equipment is performed safely and in accordance with relevant IEC technical standards (notably IEC 60079‑14 and IEC 60079‑17).

Scope

Defines the rules of procedure for the IECEx Certified Service Facilities Scheme — Part 4: inspection and maintenance. The scope covers the processes and obligations for service organisations seeking IECEx certification to perform Ex inspection and maintenance activities, the responsibilities of Ex Certification Bodies (ExCBs) in assessment and certification, required records and reports, competence and auditor requirements, and the relationship between the scheme rules and the underlying technical standards (for example IEC 60079 series). It applies to organisations providing inspection and/or maintenance services to equipment and installations in hazardous (explosive) atmospheres.

Key topics and requirements

• Scheme objectives and definitions specific to Ex inspection and maintenance services.
• Management system and documentation requirements for service facilities (quality management, control of records).
• Competence, training and assessment of personnel who perform Ex inspection and maintenance.
• Assessment and certification process carried out by Ex Certification Bodies (application, audit, on‑site visits, witness assessments).
• On‑site assessment requirements, audit evidence, non‑conformity handling and corrective actions.
• Requirements for inspection/maintenance reporting, completion conditions and record retention.
• Interfaces with core IEC technical standards (notably IEC 60079‑14 and IEC 60079‑17) and with related IECEx operational documents.
• Use of subcontractors, scope limitations and obligations for maintaining competence and traceability.

Typical use and users

Primary users are service companies that perform inspection and maintenance of Ex equipment and installations (onshore and offshore), including organisations in oil & gas, petrochemical, chemical, pharmaceutical, power generation and processing industries. Other users include Ex Certification Bodies (ExCBs), auditors, safety and compliance managers, maintenance supervisors, regulators and operators who require independent proof of competence and conformity for providers of Ex inspection and maintenance.

Related standards

Closely related documents and standards include the IEC 60079 series (in particular IEC 60079‑14 — design/selection/installation and IEC 60079‑17 — inspection and maintenance), other parts of the IECEx 03 series (IECEx 03‑0, IECEx 03‑2, IECEx 03‑3, IECEx 03‑5), IECEx Operational Documents (for example OD 314‑4, OD 316‑4), and internationally recognised conformity/assessment references such as ISO/IEC 17021, ISO/IEC 17024 and ISO/IEC 17065 where relevant for certification and assessment procedures.

FAQ

Q: What is this standard?

A: St IECEx 03‑4‑2021 is the IECEx scheme rules document for Part 4 of the Certified Service Facilities Scheme, covering inspection and maintenance of equipment and installations in explosive atmospheres. It specifies how service organisations are assessed and certified under the IECEx scheme.

Q: What does it cover?

A: It covers procedural and scheme requirements for certification — application steps, management system and documentation expectations, competence and auditor requirements, on‑site assessments and witness activities, reporting and record‑keeping rules, and how ExCBs conduct assessments for inspection and maintenance service providers.

Q: Who typically uses it?

A: Service providers that perform Ex inspection and maintenance, Ex Certification Bodies, auditors, maintenance and safety managers in industries with hazardous areas (oil & gas, petrochemicals, chemical processing, etc.), and regulators or procurement teams who need assurance of service competence.

Q: Is it current or superseded?

A: The title indicates the 2021 edition. Users should note that the IECEx scheme documents are periodically updated; a later edition of IECEx 03‑4 (scheme rules) was published by the IECEx system in December 2023 (IECEx 03‑4 Ed.4.0, published 11 December 2023). Organisations should check which edition an ExCB is assessing against and confirm contractual/contractual obligations reference the correct edition (the later edition supersedes earlier ones for new certifications after its stated effective date).

Q: Is it part of a series?

A: Yes — it is Part 4 of the IECEx Certified Service Facilities Scheme (series IECEx 03). The series includes Part 0 (general rules), and other parts covering selection of Ex equipment/installation design, installation/initial inspection, repair/overhaul and related service activities.

Q: What are the key keywords?

A: IECEx, certified service facilities, inspection, maintenance, Ex, hazardous areas, IEC 60079, ExCB, audit, competence, scheme rules.
