ATEX 2014/34/EU Guidelines – January 2026 update

In a move toward modernisation, the European Commission released the 6th Edition of the ATEX 2014/34/EU Guidelines in January 2026. While the underlying Directive remains unchanged, this new guidance represents a shift in interpretation, specifically targeting the digital transition, clarifying the murky waters of trace heaters.

DoC and instructions go digital

Reference: § 74 & § 151
The most immediate operational change is the provision for digital documentation. The 6th Edition explicitly acknowledges that the ATEX Directive does not mandate paper forms for the EU Declaration of Conformity (DoC) or instructions, but rather has to determine, and take into account the intended use of the product and the probable environmental use.

• Manufacturers can now provide the DoC and safety instructions via a machine-readable code (e.g., a QR code on the product label) or a direct URL.
• The digital information must be:
  • Accessible for at least 10 years after the product is placed on the market.
  • Easily printable and downloadable.
  • Provided in paper form upon request (at no cost).

This aligns ATEX with the new Machinery Regulation and reduces the massive volume of paper previously required for every unit shipped.

A clearer, broader exclusion for spare parts

Reference: § 33
The status of spare parts was a source of confusion, specifically whether a spare part that functions as a component in its own right needed separate certification. The 6th Edition has been reworded to simplify this.

• The new guidance explicitly states that because spare parts are primarily intended for the maintenance of a finished product already placed on the market, they are not required to comply with Directive 2014/34/EU.
• This removes the previous 5th Edition rule which stated that spare parts representing an item of equipment or component ‘normally not’ having to fulfill all obligations of the Directive.

Trace heating

Reference: § 253
The guidance for electrical trace heating systems has undergone a complete structural overhaul to align with international standards (IEC/EN 60079-30-1). The confusing terms “Stabilized Design” and “Controlled Design” have been retired.

• Type A (formerly referred to as Stabilised): Systems where the temperature class is determined by the construction of the heater itself.
• Type B (formerly referred to as Controlled): Systems where the temperature class depends on the ‘design and installation’ configuration.

The 6th Edition explicitly states that engineering or installation companies who design and install
‘Type B’ systems from various components will be taking the role of a ‘manufacturer’. This means that they will assume full liability for ATEX compliance, and need to take all measures as if they are manufacturers.

“Simple” products & battery pumps

Reference: § 38 & Market Surveillance
The Commission has tightened its grip on “simple” products and consumer goods.

• Battery pumps: A new section clarifies that battery-operated pumps for domestic use are generally excluded from ATEX but must comply with the General Product Safety Regulation (EU) 2023/988 (GPSR).
• Market Surveillance Authorities now have the right to restrict “simple” mechanical products (like hand tools) if they pose an explosion risk, even if the manufacturer claims an exemption. This closes a loophole where unsafe “simple” tools were previously difficult to regulate.

To align with the new edition, economic operators should ensure to review the changes and how these apply to their products or system integrations and update the technical documentation, and its longevity to ensure that this aligns to the latest guide notes.
