Understanding CAN CSA E60335-2-37-01: Safety Requirements for Commercial Electric Gridirons, Griddles, and Roasters
A comprehensive guide to the Canadian adoption of IEC 60335-2-37 for commercial cooking appliances
Scope and Application
CAN CSA E60335-2-37-01 is the Canadian adoption of the international standard IEC 60335-2-37, addressing the safety of commercial electric gridirons, griddles, and roasters. This standard applies to electrically operated cooking appliances intended for commercial use in restaurants, cafeterias, hotels, and similar catering establishments. The rated voltage is typically not exceeding 250 V for single-phase appliances and 480 V for poly-phase appliances.
The scope of CAN CSA E60335-2-37-01 covers stationary and transportable equipment designed for grilling, roasting, or griddle cooking. The standard does not apply to household cooking appliances, industrial-scale ovens, or appliances primarily intended for food processing. It also excludes appliances used in locations where special conditions prevail, such as explosive atmospheres or corrosive environments.
Tip: When applying CAN CSA E60335-2-37-01, always verify the latest edition and any Canadian deviations (e.g., for voltage tolerances or specific climate considerations) that may differ from the base IEC standard.
Technical Requirements and Key Specifications
Protection Against Electrical Shock and Thermal Hazards
The standard prescribes stringent requirements for insulation, creepage distances, clearances, and access to live parts. For appliances intended to be fixed or stationary, provisions for disconnection from the supply must comply with local wiring rules. Protection against thermal hazards includes maximum temperature limits for accessible surfaces, guards against contact with the cooking platen, and limits on radiant heat exposure to the operator.
Materials and Construction
Enclosures must meet minimum degrees of ingress protection (typically IPX3 or higher) to withstand cleaning and splashing. Cooking surfaces must be of materials suitable for food contact and capable of withstanding thermal cycling without degradation. Mechanical strength requirements ensure the appliance can withstand abuse during normal commercial use.
| Parameter | Requirement | Test Method |
|---|---|---|
| Leakage current | ≤ 0.5 mA per kW rated input; maximum 5 mA | IEC 60335-1, Clause 16 |
| Temperature rise (accessible surfaces) | ≤ 60 K for surfaces likely to be touched; special limits for handle and knob materials | IEC 60335-2-37, Clause 11 |
| Creepage distances and clearances | Per IEC 60335-1, with additional separation for conductive cooking residue environment | IEC 60335-1, Clause 29 |
| Resistance to moisture | IPX3 or better (splash-proof), verified by IP test chamber | IEC 60529 |
| Overload and endurance | 200 cycles of rated load without safety compromise | IEC 60335-2-37, Clause 19 |
Electromagnetic Compatibility (EMC) and Marking
Although not directly covered by this standard, compliance with the applicable CSA and ICES (Interference-Causing Equipment Standards) is required. Marking must include the appliance name, trademark, rated voltage, frequency, power input, and the CSA certification mark. Instruction manuals must provide specific warnings for commercial cleaning agents and grease removal.
Warning: The standard requires that appliance controls be designed to prevent unintended start-up. Verify that all safety interlocks are not defeatable by the operator.
Implementation Highlights for Manufacturers
Manufacturers seeking compliance with CAN CSA E60335-2-37-01 should integrate the following into their design phase:
- Material selection: Use stainless steel or heat-resistant alloys for cooking platen components. Avoid materials that may release toxic fumes under normal operating temperatures.
- Enclosure design: Ensure that grease drains are positioned to avoid accumulation near electrical connections. Use sealed connectors for wiring entering the cooking area.
- Thermosensing and control: Employ redundant thermostats or temperature limiters with manual reset to prevent overheating. All electronic controls must meet requirements for reliability and failure mode analysis.
- User interface: Provide clear, durable markings for control functions. Operator hand contact zones must remain below 55 °C steady-state in ambient commercial kitchen environments.
Success: Early integration of compliance testing—such as ingress protection checks and temperature rise evaluation—reduces certification time and cost. Partner with a recognized testing laboratory early in development.
Compliance and Certification Notes
For Canadian market access, appliances must be certified by a Standards Council of Canada (SCC)-accredited organization such as CSA Group or Intertek. Certification involves review of technical documentation, type testing, and factory inspection. Periodic follow-up inspections may be required for continuing compliance.
Important considerations:
- Year of issue: CAN CSA E60335-2-37-01 was published as an adoption of IEC 60335-2-37:2002. Subsequent amendments (A1, A2) may exist; always confirm the harmonized status with CSA.
- Provincial variations: Some Canadian provinces (e.g., Québec, Ontario) may have supplementary requirements regarding energy efficiency or bilingual labeling beyond the standard.
- Transition periods: When newer editions become available, a transition period is usually provided for existing certified products. Check the latest SCC listing.
Critical: Non‑compliance with CAN CSA E60335-2-37-01 can result in denial of certification, product seizure, or liability claims in the event of an accident. Always ensure your technical file is complete and maintained for regulatory review.
Q: What is the relationship between CAN CSA E60335-2-37-01 and the base IEC standard?
A: CAN CSA E60335-2-37-01 is the national adoption of IEC 60335-2-37, with any Canadian deviations documented in a national preface or annex. The technical content is virtually identical to the IEC edition, but the CSA version includes specific references to Canadian electrical codes and bilingual labeling requirements.

Q: Which appliances are explicitly excluded from this standard?
A: Household kitchen appliances (covered by CSA C22.2 No. 64 for household cooking), microwave ovens, deep fat fryers, industrial conveyor ovens, and appliances intended for outdoor use are outside the scope. Each of these categories falls under separate CSA or UL standards.

Q: Can a Certified Product (CSA mark) from another country be accepted in Canada?
A: Only if the certification body holds a Mutual Recognition Agreement (MRA) with SCC. Typically, products certified to CSA C22.2 No. 60335-2-37 (identical adoption) by an SCC‑accredited lab are accepted. Always confirm with your local inspection authority.

Q: How often is the standard revised?
A: The IEC base standard undergoes periodic maintenance; CSA typically adopts new editions within 2–3 years of their publication. Manufacturers should monitor CSA’s update announcements to anticipate changes to thermal limits or alarm requirements.
