Description (English):

ISO 80079-37:2016 specifies the requirements for the design and construction of non-electrical equipment, intended for use in explosive atmospheres, protected by the types of protection constructional safety "c", control of ignition source "b" and liquid immersion "k". This part of ISO/IEC 80079 supplements and modifies the requirements in ISO 80079-36. Where a requirement of this standard conflicts with the requirement of ISO 80079-36 the requirement of this standard takes precedence. Types of protection "c", "k" and "b" are not applicable for Group I, EPL Ma without additional protective precautions. The types of ignition protection described in the standard can be used either on their own or in combination with each other to meet the requirements for equipment of Group I, Group II, and Group III depending on the ignition hazard assessment in ISO 80079-36. Keywords: constructional safety "c", control of ignition source "b" and liquid immersion "k"

Abstract

Overview

EN ISO 80079-37:2016 specifies design and construction requirements for non‑electrical equipment intended for use in explosive atmospheres, using the non‑electrical types of protection constructional safety "c", control of ignition source "b", and liquid immersion "k". This part supplements and modifies ISO 80079‑36 and takes precedence where conflicts occur. The standard applies to equipment for Groups I, II and III (subject to ignition hazard assessment in ISO 80079‑36); types "c", "b" and "k" are not applicable to Group I, EPL Ma without additional precautions. EN ISO 80079‑37 supports conformity with EU Directive 2014/34/EU (ATEX) and supersedes earlier EN 13463 parts.

Key topics and technical requirements

The standard focuses on preventing ignition sources inherent to mechanical and constructional design. Major topics include:

Determination of suitability and how to apply protection types "c", "b" and "k".
Ingress protection requirements for dust and liquids to prevent hazardous contact with explosive atmospheres.
Design rules for seals (unlubricated, lubricated, stuffing boxes) and moving parts to avoid frictional or mechanical ignition.
Lubrication, coolants and fluids: selection and containment to prevent vapor or aerosol hazards.
Vibration, clearances and tolerances to prevent hot surfaces, friction or impact ignition.
Bearings, power transmission systems (gears, belts, chains), clutches, variable speed couplings and flexible couplings - design and operational constraints to limit ignition risks.
Brakes and braking systems, and other mechanical elements where heat buildup or sparks could occur.
Information for marking and instructions to support safe installation, operation and maintenance.

Practical applications and users

EN ISO 80079‑37 is essential for:

Mechanical designers and manufacturers producing non‑electrical equipment for hazardous areas (e.g., pumps, gearboxes, conveyors, mixers).
Safety and process engineers performing ignition hazard assessments (in conjunction with ISO 80079‑36).
Certification and notified bodies assessing conformity to ATEX/IECEx requirements.
Maintenance teams and asset owners who need to apply correct installation, lubrication and inspection regimes to keep equipment safe in explosive atmospheres.

Using constructional safety "c", control of ignition source "b" and liquid immersion "k" - alone or combined - helps manage diverse ignition scenarios for equipment in mining, chemical, petrochemical, grain handling, and other industries with explosive atmospheres.
