Full title and description

St IECEx OD 314-4-2021 — IECEx Certified Service Facilities Scheme – Part 4: Ex inspection and maintenance. Quality management system requirements for IECEx service facilities providing inspection and maintenance services related to equipment and installations for use in explosive atmospheres.

Abstract

This Operational Document (OD 314-4, Edition 3.0) sets out the quality management system requirements, assessment expectations and related procedural guidance for service facilities that perform inspection and maintenance of Ex (explosive-atmosphere) equipment and installations. It is intended to ensure that service facilities operate consistently and safely, demonstrating competence, traceability and control of Ex-related work.

General information

• Status: Active.
• Publication date: 20 December 2021.
• Publisher: IECEx (IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres).
• ICS / categories: Electrical equipment for explosive atmospheres — ICS 29.260.20 (explosive atmospheres / Ex equipment).
• Edition / version: Edition 3.0 (OD 314-4 Ed.3.0).
• Number of pages: Not specified on the IECEx listing; typical Operational Documents are short guidance documents (estimated ~20–30 pages). (page count shown here is an approximate estimate.)

Scope

Defines the quality management system requirements and related guidance for IECEx certification of service facilities that carry out inspection and maintenance work on equipment and installations intended for use in explosive atmospheres. The document covers responsibilities, competence, procedures, record keeping, control of nonconforming work and requirements for facility assessments under the IECEx Certified Service Facilities Scheme.

Key topics and requirements

• Quality management system criteria specific to Ex inspection and maintenance operations.
• Personnel competence, training and authorisation for Ex work.
• Procedures for inspection, planned maintenance, and post-maintenance verification.
• Control of tools, calibration and test equipment used for Ex tasks.
• Traceability, documentation and record-keeping (service reports, certificates, maintenance records).
• Control of nonconforming work, repairs and reporting of modifications affecting Ex protection.
• Requirements and expectations for IECEx assessment, surveillance and certification of service facilities.
• Interface and alignment with relevant technical standards for Ex equipment and installations (e.g., IEC 60079 series).

Typical use and users

Used by service facility managers and quality managers seeking IECEx certification, auditors and assessors performing IECEx assessments, Ex installation and maintenance engineers, asset owners/operators in hazardous industries (oil & gas, petrochemical, mining, chemical), and regulatory/compliance teams that require documented competence and controlled maintenance of Ex equipment.

Related standards

Closely related to other IECEx Operational Documents in the OD 314 and OD 316 families (OD 314-2, OD 314-3, OD 314-5; assessment procedure equivalents in OD 316-x) and to the IEC 60079 series (equipment, installation and maintenance requirements for explosive atmospheres). It also interfaces with general conformity and testing standards and accreditation requirements such as ISO/IEC 17025 and relevant national regulations.
