The new EN 298:2022 standard for Australian certification

EN 298:2012 was superseded in November 2022 and replaced with EN 298:2022. Being the reference standard to assess programmable electronic systems under AS 4625, burner controls certified to AS 4625 will also be affected. As required in the GTRC rules, the affected certificates shall be upgraded to the new standard within two years from publication (November 2024).

In addition, the changes in EN 298 will affect appliances incorporating an automatic burner control, as AS/NZS 5263.0 calls for AS 4625 and EN 298 for the evaluation of automatic burner control with a programmable electronic system. Hence the appliance manufacturers need to ensure their suppliers are responding to this change.

As the certificate holder, you should review the changes to establish what impact this will have on your products within a reasonable time. We recommend that you complete this review and develop an action plan to ensure your products continue to comply with latest requirements in EN 298:2022.

Manufacturers may choose to have this review performed independently by a Conformity Assessment Body (CAB) such as BSI, and our extensive experience in testing and certifying against both versions of the standards may save significant time in the process.

EN 298:2022 has been published

EN 298:2012 was superseded in November 2022 and replaced with EN 298:2022. As AS 4625 calls for EN 298 for the evaluation of electronic flame safeguards and flame detectors, the changes in this standard upgrade are also required in AS 4625.

We recommend that you review the new standard, but in summary, the following changes have been made between EN 298:2012 and previous version EN 298:2022

  • Alignment with EN 13611:2019 and addition of the high-temperature operation (HTO). Relevant changes have been made throughout the standard to reference HTO regarding performance tests and instructions
  • 6.6.1 Design and construction requirements. Additional Software Clause EN 60730-1:2016 Annex H.11.12.4 Remotely actuated control Functions
  • 6.6.3 Class B. The clause was previously N/A but has now been made a requirement for a Reset function
  • 6.6.4 Class C. Software now evaluated to EN 60730-1:2016 Annex H.11.12
  • 7.8 Data exchange. New requirement added
  • 9.3 Voltage dips and interruptions. Tests at 30% decrease for 1.5, 25 & 50 cycles have been added
  • 9.5 Surge immunity tests. Tests of the power supply cable at 2kV LN-LN added (previously N/A). Plus, Test of control cables/balanced circuits LN-GND increased to 1.0 & 2.0 kV (Previously 0.5 & 1kV)
  • 9.8 Immunity to radiated disturbances induced by radio frequency fields. Bandwidth 2.0–2.7 GHz added. 6 x ISM, GSM & DECT spot frequencies changed/added
  • 9.11 Harmonics and interharmonics including mains signalling at a. c. power port, low frequency immunity tests. Clause added
