EPIT Yellow Book - 6th Edition Launch

We’re pleased to announce the release of the latest edition of the Yellow Book.

A trusted reference for hazardous area professionals, the latest edition has been updated to align with the latest IEC standards while maintaining the practical guidance engineers rely on for installation, inspection and maintenance of equipment in potentially hazardous areas.

Designed with real world environments in mind, the Yellow Book now also features durable no-tear paper, making it even better suited for use both on site and in the office.

What’s New In The 6th Edition

The latest edition of the EPIT Yellow Book introduces several updates to ensure the guidance remains aligned with current standards and practical for day-to-day use.

✔ Updated to the latest IEC 60079-14:2024 standard
The guidance has been reviewed and updated to reflect the latest IEC requirements for installations in explosive atmospheres.

✔ Expanded coverage including non-electrical equipment
New content now includes information relating to non-electrical equipment, providing clearer guidance across a wider range of hazardous area applications.

✔ Updated cable gland selection flowchart
A refreshed flowchart helps engineers determine the appropriate cable gland based on installation parameters and equipment protection methods.

✔ Durable no-tear pages
Printed on durable no-tear paper, the Yellow Book is designed to withstand the demands of site work and frequent use.

✔ A trusted industry resource
Providing practical ATEX & IECEx guidance for professionals involved in:

Hazardous area design
Equipment selection
Installation planning
Inspection and maintenance
Compliance and verification
