No, they are different documents from different countries. CEI 31-35 is an Italian guide for explosive gas atmospheres. GB/T 16895 is a Chinese national standard for low-voltage electrical installations. They are not interchangeable.

Refineries, distillation columns, and chemical storage depots.

Please note that because this is a copyrighted technical standard published by the Comitato Elettrotecnico Italiano (CEI)

While EN 60079-10-1 provides the overarching theoretical framework and qualitative guidelines for hazardous area classification, CEI 31-35 delivers the practical calculations, specific examples, and quantitative methodologies required to implement those rules under Italian law. Core Objectives of the Standard

the impact of ventilation on reducing explosion risks. cei 31-35 pdf

Tied heavily to older versions of CEI EN 60079-10-1. It introduced complex math formulas for calculating the background dilution and discharge rates of flammable leaks.

Releases that are not expected during normal operations and occur strictly due to an equipment malfunction (e.g., pipe flange failure). Ventilation and Dilution Calculations

: Digital copies are easier to integrate into safety reports and audits.

By combining the release rate of the substance, its physical properties (like density and boiling point), and the local ventilation parameters, the CEI 31-35 guide allows engineers to calculate the precise distance ( No, they are different documents from different countries

Consider a real-world scenario: A station has a mechanical lever frame and relay interlocking, but needs to add an axle counter interface to a new interlocking. Using CEI 31-35:
