Behind every safety certification mark on your air fryer - whether it is UL Listed, ETL Certified, CE marked, or carries a GS Mark - there is a specific technical standard that defines what "safe" actually means. For portable cooking appliances like air fryers, that foundational standard is IEC 60335-2-9.
This is a technical document, but we think parents deserve to understand what standard their appliance was actually tested against. Here is what it covers, what it does not, and why it matters.
What IEC 60335-2-9 Is
IEC 60335-2-9 is published by the International Electrotechnical Commission (IEC), an international standards organization based in Geneva, Switzerland. The full title is "Household and similar electrical appliances - Safety - Part 2-9: Particular requirements for grills, toasters and similar portable cooking appliances."
It is part of the IEC 60335 family, which consists of:
- IEC 60335-1 - General requirements for household electrical appliance safety (the base standard)
- IEC 60335-2-X - Particular requirements for specific appliance types (over 100 parts)
Part 2-9 specifically applies to portable cooking appliances that use electricity for heating. This includes air fryers, toaster ovens, indoor grills, waffle makers, sandwich presses, rotisseries, and similar countertop cooking devices. The standard defines safety requirements beyond those in the general Part 1, accounting for the specific hazards of cooking appliances - high temperatures, food contact, grease accumulation, and extended operation times.
The current edition is Edition 7 (IEC 60335-2-9:2019, with Amendment 1:2023), though national adoptions may reference slightly different revision dates.
How IEC 60335-2-9 Connects to National Standards
This is where the standard becomes practically important. IEC 60335-2-9 is not directly enforceable in any country - it is an international reference document. Individual countries adopt it into their national standards, sometimes with modifications:
United States - UL 1026 (Standard for Safety for Electric Household Cooking and Food Serving Appliances) is the national standard for cooking appliances. UL 1026 is harmonized with IEC 60335-2-9, meaning it covers the same core requirements but includes US-specific deviations to align with American electrical infrastructure (120V/60Hz), National Electrical Code requirements, and OSHA regulations. When your air fryer is UL Listed or ETL Certified, it was tested to UL 1026.
European Union - EN 60335-2-9 is the European adoption. The "EN" prefix indicates it has been adopted by CENELEC (European Committee for Electrotechnical Standardization). It is virtually identical to the IEC version with minor European-specific additions. CE marking and GS Mark certification for cooking appliances reference this standard.
Canada - CSA C22.2 No. 64 covers household cooking appliances and is harmonized with both IEC 60335-2-9 and UL 1026.
Other countries - Australia (AS/NZS 60335-2-9), China (GB 4706.14), Japan (JIS C 9335-2-9), and most other major markets have national adoptions of this standard.
The harmonization means that an air fryer tested to any properly adopted version of IEC 60335-2-9 has been evaluated against substantially the same safety requirements, regardless of which country's version was used.
