Full title and description

ISO 80079-36:2016 — Explosive atmospheres — Part 36: Non-electrical equipment for explosive atmospheres — Basic method and requirements. This International Standard specifies basic methods and mandatory requirements for the design, construction, testing and marking of non‑electrical Ex equipment, Ex components, protective systems, devices and assemblies that have their own potential ignition sources and are intended for use in explosive atmospheres (gases, vapours, mists and dusts). Hand tools and manually operated equipment without energy storage are excluded; safety requirements other than those directly related to ignition risk are not specified.

Abstract

ISO 80079-36:2016 provides the basic method and requirements to assess and mitigate ignition sources in non‑electrical equipment intended for explosive atmospheres, and establishes expectations for design, construction, testing and marking so equipment can be placed on the market and used in environments where explosive atmospheres may occur. The standard defines applicable atmospheric conditions (temperature range −20 °C to 60 °C, pressure 80 kPa to 110 kPa and normal air oxygen content) and supplements/modifies the general requirements of IEC 60079-0 for non‑electrical equipment.

General information

• Publication date: February 2016 (Edition 1, 2016-02).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 29.260.20 (explosion protection / non‑electrical equipment).
• Edition / version: Edition 1 (2016).

Key lifecycle notes: a corrigendum (ISO 80079-36:2016/Cor 1:2019) has been published and the standard was reviewed/confirmed in the ISO five‑year review process (review activity noted in 2021). The standard is the foundational part for non‑electrical protection types and is coupled with Part 37 which gives constructional safety and specific protection-type requirements.

Scope

Specifies requirements for the design and construction of non‑electrical equipment, components and assemblies that contain their own potential ignition sources and are intended for use in explosive atmospheres of groups I, II and III (mining and above‑ground applications). The scope excludes simple hand tools and manually operated devices without energy storage, and does not address process safety unrelated to ignition risk. The standard sets the normative atmospheric conditions under which compliance is assumed and indicates where it supplements or modifies IEC 60079-0.

Key topics and requirements

• Definition and classification of non‑electrical equipment and Ex components intended for explosive atmospheres.
• Design principles to eliminate or control potential ignition sources within mechanically driven, pneumatic or hydraulic equipment.
• Construction and material requirements to limit ignition risks (clearances, enclosures, sealing, surface temperature control).
• Testing and verification methods for demonstrating compliance with ignition‑risk requirements.
• Marking, documentation and information to the user (identification of equipment protection level, usage limits and atmospheric conditions).
• Interaction and precedence with IEC 60079‑0 and applicability of additional parts (for example ISO 80079‑37 for protection types “c”, “b” and “k”).

Typical use and users

Manufacturers and designers of mechanical, pneumatic and hydraulic equipment (pumps, gearboxes, couplings, brakes, fans, compressors, engines, assemblies) intended for potentially explosive atmospheres; testing and certification bodies; notified bodies for regulatory compliance (for example ATEX conformity assessment in Europe); engineering teams performing equipment selection and ignition‑hazard assessments; and standards committees developing related documents. The standard is used to demonstrate conformity to market and regulatory requirements for placing non‑electrical Ex equipment on the market.

Related standards

ISO 80079-36 is part of the ISO/IEC 80079 series for explosive atmospheres. Closely related and commonly used together are IEC/ISO 80079-37:2016 (non‑electrical types of protection constructional safety “c”, control of ignition sources “b”, liquid immersion “k”), and IEC 60079-0 (general requirements for electrical equipment for explosive atmospheres), among other parts of the 80079 series that address specific protection concepts and equipment types. National/adopted variants (EN ISO 80079-36) and corrigenda apply regionally.

FAQ

Q: What is this standard?

A: ISO 80079-36:2016 is an International Standard that defines the basic methods and mandatory requirements for the design, construction, testing and marking of non‑electrical equipment and components that have potential ignition sources and are intended for use in explosive atmospheres.

Q: What does it cover?

A: It covers risk‑based measures to eliminate or control ignition sources arising from non‑electrical equipment (mechanical, hydraulic, pneumatic, etc.), prescribes constructional and testing requirements, sets normative atmospheric conditions for assumed operation, and describes marking and documentation needed for safe use. Hand tools without energy storage are excluded.

Q: Who typically uses it?

A: Equipment manufacturers, design engineers, testing and certification bodies, conformity assessment organizations (including those applying ATEX and similar regional regulations), and safety engineers performing equipment selection or hazard assessments.

Q: Is it current or superseded?

A: The 2016 edition (Edition 1) was published in February 2016, a corrigendum was issued in 2019, and the standard was reviewed/confirmed through ISO's periodic review process (review activity recorded in 2021). Check with your national body or ISO for any work in progress or newer editions after 2021.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 80079 series on explosive atmospheres (multiple parts address electrical and non‑electrical equipment and specific protection types). ISO 80079-37 (2016) provides additional requirements for specific non‑electrical protection types and is intended to be used together with ISO 80079-36.

Q: What are the key keywords?

A: explosive atmospheres; non‑electrical equipment; Ex components; ignition sources; equipment protection level (EPL); ATEX; mechanical explosion protection; testing; marking.
