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.
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.
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.
IEC 60335-2-9 defines specific test procedures and pass/fail criteria across multiple safety dimensions:
This section is critical for families. IEC 60335-2-9 is specifically and exclusively an electrical and mechanical safety standard. It does not evaluate:
Coating chemistry - Whether the nonstick coating contains PTFE, PFAS, or other substances of concern is entirely outside scope. A PTFE-coated air fryer basket and a stainless steel basket are evaluated identically under this standard - only their electrical and thermal properties matter, not their chemical composition.
Food-contact material safety - Migration of chemicals from cooking surfaces into food is governed by food-contact regulations (FDA 21 CFR in the US, EU Regulation 1935/2004 in Europe), not by IEC 60335.
Temperature accuracy - The standard tests that thermal protection devices work correctly, but it does not verify that the temperature displayed on the control panel matches the actual internal temperature. An air fryer that runs 30 degrees hotter than advertised can still comply.
Cooking performance - Evenness of cooking, speed, capacity claims, and energy efficiency are not safety criteria.
Electromagnetic emissions - EMC (electromagnetic compatibility) is covered by a separate standard family (IEC 61000 series, or FCC Part 15 in the US).
Every safety-certified air fryer sold in the world was tested against a national version of IEC 60335-2-9. In the US, that means UL 1026. In Europe, EN 60335-2-9. The standard ensures your air fryer's electrical system, heating element, thermal protection, and mechanical construction are safe. It does not evaluate what the cooking basket is coated with. When we assess air fryers at R3, we look at both the safety certification (based on this standard) and the coating materials (based on separate evaluation).
IEC 60335-2-9 does not address health concerns related to food-contact materials, coating chemistry, or chemical exposure. It is strictly an electrical and mechanical safety standard. The health-relevant questions for air fryers - whether coatings contain PFAS or PTFE, whether materials migrate into food at cooking temperatures - fall under separate food-contact regulations in each country.
International: Published by the International Electrotechnical Commission (IEC). Not directly enforceable - serves as the base document for national adoptions.
United States: Harmonized through UL 1026. Air fryers tested for UL or ETL listing are evaluated against UL 1026, which incorporates IEC 60335-2-9 requirements with US-specific modifications.
European Union: Adopted as EN 60335-2-9. Referenced by the Low Voltage Directive (2014/35/EU) for CE marking compliance. Also the basis for GS mark testing.
Canada: Harmonized through CSA C22.2 No. 64.
Global: Adopted in over 80 countries through national standards bodies affiliated with the IEC.

How to verify
1. Confirm your air fryer carries a recognized safety mark (UL, ETL, CE, GS, or CSA). 2. For US products: verify the UL or ETL listing in the appropriate directory (ul.com/database or ramuk.intertekconnect.com). The listing should reference UL 1026. 3. For European products: check the Declaration of Conformity (usually in the manual or available from the manufacturer) for a reference to EN 60335-2-9. 4. For GS-marked products: verify the certificate in the issuing body's database (certipedia.com for TUV organizations). 5. The standard itself can be purchased from the IEC webstore (webstore.iec.ch) for reference, though this is mainly relevant for engineers and compliance professionals.

Yes - it is the foundational international safety standard for portable cooking appliances, which includes air fryers. Your air fryer was not tested directly to IEC 60335-2-9 itself, but to a national adoption: UL 1026 in the US, EN 60335-2-9 in Europe, or CSA C22.2 No. 64 in Canada. These national versions are harmonized with the IEC standard, meaning they cover substantially the same safety requirements.
No. IEC 60335-2-9 is exclusively an electrical and mechanical safety standard. It does not evaluate nonstick coating chemistry, PFAS content, PTFE presence, or food-contact material safety. Those concerns are governed by separate food-contact regulations - FDA 21 CFR in the US and EU Regulation 1935/2004 in Europe.
UL 1026 is the US national adoption of IEC 60335-2-9. They share the same core safety requirements, but UL 1026 includes US-specific modifications to align with 120V/60Hz electrical infrastructure, National Electrical Code requirements, and OSHA regulations. Think of IEC 60335-2-9 as the international template and UL 1026 as the American version customized for US conditions.
Any air fryer that carries a recognized safety certification mark (UL, ETL, CE, GS, CSA) was tested to a national adoption of this standard. Air fryers sold without any safety certification mark - particularly inexpensive models from unknown brands on marketplace platforms - may not have been tested to any standard at all, which is why we recommend only purchasing certified appliances.
The IEC revises the standard periodically. The current base is Edition 7 (2019) with Amendment 1 (2023). Updates address new appliance designs, emerging hazards, and evolving technology. National adoptions (UL 1026, EN 60335-2-9) update on their own schedules but generally track IEC revisions within a few years.
Yes, but it is a paid document. The IEC sells it through their webstore (webstore.iec.ch). National versions are available through their respective publishers (UL for UL 1026, CENELEC for EN 60335-2-9). The documents are technical and written for engineers and compliance professionals, but they are publicly purchasable if you want to review the specific test procedures.
It means your air fryer has passed rigorous testing for electrical and mechanical safety - it should not shock you, catch fire, overheat dangerously, or fall apart under normal use. That is meaningful and important. But 'safe' in the broader sense that families care about - including coating material safety and chemical exposure - requires additional verification beyond this standard's scope.
Long-term degradation - Testing is performed on new-condition samples. How components, coatings, and seals perform after years of use is not assessed.
Understanding that IEC 60335-2-9 (and its national equivalents) is the foundation of air fryer safety certification helps families evaluate safety claims more accurately:
The standard evolves over time as new appliance types and hazards emerge:
Air fryers were not a mainstream product category when earlier editions were written. The standard's language about "grills, toasters and similar portable cooking appliances" has been interpreted to encompass air fryers (which are technically rapid air circulation convection ovens), and current editions explicitly accommodate fan-assisted cooking appliances.
