CEI 31-35, titled "Explosive atmospheres - Guide for the classification of hazardous areas for the presence of gas in application of CEI EN 60079-10-1 (CEI 31-87)," is an Italian technical guide published by the Italian Electrotechnical Committee (CEI). It serves as a practical support tool for engineers and safety technicians to correctly identify and classify hazardous areas where a potentially explosive gas atmosphere can form.

The standard is the essential technical guide issued by the Comitato Elettrotecnico Italiano (CEI) for classifying hazardous areas where explosive gas atmospheres may form. Designed as a companion application guide to the European and international standard CEI EN 60079-10-1 (CEI 31-87) , this document provides engineers, health and safety managers, and plant designers with the detailed calculations, definitions, and practical methodologies required to fulfill ATEX safety directives.

The CEI 31-35 standard provides guidance on the application of IEC 61508 and IEC 61511, including:

While international standards like IEC 60079-10-1 establish overarching principles for zone mapping, they often lack highly specific calculation methods for complex engineering scenarios. CEI 31-35 bridges this gap by offering:

The CEI 31-35 guide was first developed in 1999 by the subcommittee of the CEI to help Italian technicians interpret the then-new European standard EN 60079-10. The guide has undergone several revisions to stay aligned with updates to the reference standards.
