Overview

EN 60079-29-1:2016/A1:2022 (CENELEC adoption of IEC 60079-29-1:2016/A1:2020) is an amendment that updates the performance requirements and type‑testing provisions for detectors of flammable gases used in explosive atmospheres. The amendment was approved by CENELEC (2020-04-28) and includes informative Annex ZZ describing the relationship with Directive 2014/34/EU, providing a presumption of conformity when the standard is cited in the Official Journal.

This amendment clarifies test sequencing, test-sample usage, electromagnetic compatibility (EMC) testing, and performance criteria applicable to gas detection equipment and systems intended for hazardous locations.

Key Topics

• Scope and status: Amendment to EN 60079-29-1:2016; aligns the European standard with IEC 60079-29-1:2016/A1:2020 and supports essential requirements of the ATEX Directive (2014/34/EU) via Annex ZZ.

• Type testing and test samples: Most applicable type tests are to be carried out on the same sample. Separate samples are permitted for specific tests (e.g., subclauses 5.4.4.3–5.4.4.6, 5.4.16, 5.4.20, 5.4.21). If a sample fails during testing, the laboratory and manufacturer shall agree which tests require repetition and document the decision in the test report.

• Test sequence: The unpowered storage test is performed before other tests. The vibration test is normally executed after unpowered storage as pre-conditioning, with exceptions for the specified separate-sample tests.

• EMC requirements: EMC testing is referenced to IEC 61326‑1:2012, Table 2. The amendment defines hierarchical performance criteria (A, B, C) for functions associated with gas detection and measurement, and specifies how standard test gas or equivalent simulation may be used during EMC exposure. For multi‑gas portable equipment, tests must be performed with a full set of typical sensors.

• Performance criteria: Criteria A, B and C describe allowable degradations, fault indications, or temporary loss of function during EMC tests, and require self-recovery or easy restoration of functionality post-test where applicable.

Applications

• Selection and certification of fixed and portable flammable‑gas detectors for industrial sites (petrochemical, chemical, mining, utilities).
• Type testing and factory assessment to demonstrate reliable detection, alarm set‑point integrity, EMC resilience and compliance for equipment used in potentially explosive atmospheres.
• Supporting technical files for CE/ATEX conformity assessment when the standard is referenced in the Official Journal.

Related Standards

• IEC 60079‑29‑1:2016/A1:2020 (base international document)
• IEC 61326‑1:2012 (EMC testing referenced)
• Directive 2014/34/EU (ATEX) - see Annex ZZ for correspondence and presumption of conformity

For implementers, manufacturers and testing labs, EN 60079-29-1:2016/A1:2022 provides practical, testable criteria to ensure gas detectors operate reliably under the environmental, mechanical and electromagnetic stresses encountered in hazardous locations.
