CAN CSA E60335-2-48-01: Safety Requirements for Commercial Electric Grills and Toasters
Comprehensive Guide to the Canadian Adoption of IEC 60335-2-48 for Commercial Cooking Appliances
CAN CSA E60335-2-48-01 is the Canadian adoption of IEC 60335-2-48, the particular safety standard for commercial electric grills and toasters. Specified within the CAN/CSA-C22.2 No. 60335 series (Safety of Household and Similar Electrical Appliances), this standard addresses the specific hazards and performance expectations for equipment used in commercial kitchens, cafeterias, and similar professional food‑service environments. Engineers, certifiers, and manufacturers must understand the scope, technical provisions, and compliance pathways outlined in this document to ensure safe, reliable products in the Canadian market.
Scope of CAN CSA E60335-2-48-01
This standard applies to commercial electric grills and toasters manufactured for stationary or movable use, with a rated voltage not exceeding 600 V. The scope includes:
- Electric grills of all types (contact, radiant, conveyor, and contact‑toasting grills).
- Commercial toasters (pop‑up, conveyor, and batch types).
- Apparatus incorporating supplementary heating elements, timer controls, and thermal protection devices.
Excluded from the standard are household toasters and grills (covered by CAN/CSA‑C22.2 No. 60335‑2‑9), appliances designed exclusively for industrial food processing, and equipment that uses gas or other non‑electric energy sources. The standard aligns with the general safety philosophy of IEC 60335‑1 while introducing modifications that address the specific risks associated with high‑power, high‑temperature, and high‑usage commercial cooking appliances.
Tip: The scope explicitly requires that the appliance be intended for operation by untrained staff in a commercial setting. Design considerations must therefore account for potential misuse, e.g., leaving the appliance unattended with flammable materials nearby.
Key Technical Requirements
All requirements of the General Standard (IEC 60335‑1) apply unless modified by this Part 2‑48. The following table summarises the most critical technical provisions specific to commercial grills and toasters.
| Requirement | Specification | Remarks |
|---|---|---|
| Rated voltage & frequency | ≤ 600 V, 50‑60 Hz | Test for single‑phase and three‑phase configurations |
| Temperature rise limits | Enclosure surface ≤ 85 K (accessible parts) Handle/grip ≤ 35 K | Measured under normal operating conditions with maximum load |
| Creepage distances & clearances | Per IEC 60335‑1 with additional 0.5 mm separation for parts exposed to grease or moisture | Applied to switches, thermostats, and terminal blocks |
| Stability & mechanical hazards | Tilt angle ≥ 10° (movable appliances); guards for rotating parts (conveyor types) | Testing with tilting platform and simulated drawer/pull loads |
| Over‑temperature protection | Thermal cut‑out (auto‑reset or manually reset) required for all heating elements | Must operate before the appliance exceeds the temperatures of Table 3 of IEC 60335‑1 |
| Resistance to moisture & grease ingress | IPX4 minimum; drainage provisions for spillage | Drip‑test and grease‑impact test (Clause 15.101) |
| Leakage current | ≤ 0.75 mA per kW rated input (max 5 mA) | Measured at rated voltage with all heating elements energised |
| Electrical endurance | 6000 cycles (switches, thermostats); 3000 cycles for relays | After endurance test, voltage withstand test at 1000 V |
Additional Technical Provisions
CAN CSA E60335-2-48-01 introduces modifications to the General Standard for grease‑fire risk mitigation. For example, Clause 22.101 requires that any appliance with a cooking surface that can accumulate grease must be fitted with a drip tray that can withstand ignition tests. Furthermore, Clause 30.101 (abnormal operation) requires the appliance to pass an extended thermal test where the heating elements are energised while the thermostat is short‑circuited; no flame or molten metal may escape.
Important: Designers should pay close attention to the clearance requirements near the cooking surface – the standard mandates a minimum distance of 150 mm between the heating zone and any electrical insulation that does not meet a glow‑wire rating of 850 °C.
Implementation and Testing Highlights
Testing under CAN CSA E60335-2-48-01 is based on the concept of “worst‑case” loading. The standard defines specific test loads for grills (bread slices, butter pats) and toasters (white bread loaves with controlled moisture content). The appliance is operated at 1.15 times the rated power input for temperature‑rise measurement, and at 1.25 times for overload conditions.
Critical Test Sequences
- Normal operation test (Clause 11): Running at rated voltage until steady state, with a grease‑simulant spread on the cooking surface for grills.
- Toasting reproducibility test (Annex AA): For pop‑up toasters, the toast colour must remain within a defined tolerance over ten consecutive cycles.
- Grease fire simulation (Clause 30.102): A small amount of combustible oil is placed on the drip tray; the heating elements are energised at maximum setting. The test is passed if no sustained flame develops.
- Mechanical strength of handles and knobs (Clause 21.101): A static force of 250 N applied in the most unfavourable direction; handles must not detach or fracture.
Success: Manufacturers who integrate thermal cut‑outs with manual reset (in line with Clause 19.101) can significantly simplify compliance, as this is the preferred method for meeting abnormal‑operation requirements.
Compliance and Certification Notes
In Canada, compliance with CAN CSA E60335-2-48-01 is required for obtaining CSA certification and for meeting the Safety Standards of the Canadian Electrical Code (CE Code, Part I). Certification involves a factory inspection, product testing, and ongoing surveillance. Key points to consider:
- All appliances must bear the CSA mark or a recognised equivalent (e.g., cUL, cETL) that covers the scope of 60335-2-48.
- When differences exist between the Canadian edition and the base IEC standard, the Canadian deviations (noted in the front matter) take precedence. For example, the grounding requirements are stricter in Canada: a dedicated green bonding conductor is required for all exposed metal parts.
- Components such as power cords must comply with CAN/CSA‑C22.2 No. 49 (flexible cords) and be terminated with a plug rated for the appliance current.
- The standard includes a national annex for voltage tolerance: appliances rated 600 V or less may be tested at either 480 V or 600 V to cover both common supply configurations.
Caution: Using a household‑grade component in a commercial grill or toaster (e.g., non‑rated thermal fuse) can lead to non‑compliance with Clause 24.1.4, which demands components rated for at least 150% of the operating temperature under fault conditions.
Finally, manufacturers should be aware that CAN CSA E60335-2-48-01 was reaffirmed in 2021, with an edition date of 2001 (hence the “‑01” suffix). While the core safety principles remain stable, the CSA Group periodically publishes amendments. It is essential to always reference the latest version (current as of 2026) and any applicable Interpretations issued by the CSA Technical Committee on Consumer and Commercial Products.
Frequently Asked Questions
Q: Can a commercial grill designed for the European market be certified directly under CAN CSA E60335-2-48-01?
A: Not without review. While the Canadian standard is technically identical to IEC 60335-2-48, there are national differences (e.g., supply voltage, grounding requirements, and plug configurations) that must be addressed. A CB test certificate from an IECEE member body can streamline the process, but the product must still be evaluated for the specific Canadian deviations.

Q: Does CAN CSA E60335-2-48-01 apply to electric grills that are also capable of using charcoal or gas?
A: The standard covers only the electric heating function. If the appliance contains a gas or charcoal burning system, it must also comply with the relevant CSA gas appliance standard (e.g., CAN/CSA‑C22.2 No. 0.4 for gas‑fired appliances). When the electric part is independent, it can be evaluated separately.

Q: What is the process for a component such as a thermostat to gain recognition under this standard?
A: Components are not individually certified to 60335-2-48; instead, they must be included in the appliance’s certification. However, the manufacturer can provide test data showing that the component complies with the applicable clause of IEC 60335-1 and the Canadian deviations. Many suppliers offer components that carry cURus or CSA component acceptance marks for temperature limiters and thermal cut‑outs.
