Understanding CAN/CSA C22.2 No. 62031-13 (2018): Safety Specifications for LED Modules in Canada
A comprehensive guide to the Canadian adoption of IEC 62031 for LED module safety and compliance
The adoption of LED technology for general lighting continues to expand, making robust safety standards essential. CAN/CSA C22.2 No. 62031-13 (2018) is the Canadian national standard for the safety of LED modules intended for general lighting purposes. It is the Canadian adoption of the international IEC 62031 standard, with modifications to align with Canadian electrical codes and climatic conditions. This article provides a detailed overview of the scope, technical requirements, implementation considerations, and compliance pathways for this critical standard, supporting manufacturers and engineers in bringing safe, compliant LED products to the Canadian market.
Scope and Application
CAN/CSA C22.2 No. 62031-13 applies to LED modules for general lighting under the following conditions:
- Supply voltage not exceeding 250 V (AC 50/60 Hz or DC)
- Designed for indoor or outdoor use (depending on declared IP rating)
- Includes both integral (containing control gear) and non-integral LED modules
- Excludes modules that are integral parts of luminaires already covered by other standards (e.g., C22.2 No. 250.13)
The standard covers safety aspects such as electric shock, thermal hazards, mechanical hazards, and abnormal operation. It does not cover performance or lifetime, nor does it address photobiological safety in detail (referenced to IEC/CSA 62471).
Tip: For complete luminaire certification, manufacturers often combine compliance with CAN/CSA C22.2 No. 250.13 (or No. 250.0) and the applicable LED module standard. Check with your certification body for a single evaluation to avoid duplication.
Technical Requirements and Key Parameters
Classification and Marking
LED modules must be marked with:
- Rated voltage, frequency, and power
- Maximum case temperature (tc)
- Class of protection (I, II, or III)
- IP rating if intended for outdoor or damp locations
- Canada-specific markings: for Class II modules, the double-square symbol; for Class P (protected) modules, appropriate designation
Electrical Safety
Creepage distances and clearances must comply with CSA C22.2 No. 60747-1 (or as specified in the national differences of IEC 62031). Dielectric strength tests are performed at:
- 1500 V AC for basic insulation
- 3000 V AC for reinforced insulation
Thermal and Mechanical
The standard defines maximum temperature limits for accessible surfaces, internal windings, and the declared tc point. Mechanical tests include secure mounting, screw torque, and impact resistance (e.g., 0.5 J for portable modules).
| Parameter | Requirement | Test / Reference |
|---|---|---|
| Dielectric Strength (basic) | 1500 V AC / 60 s | Between live parts and accessible parts |
| Creepage / Clearance | Per Table 2 of CSA C22.2 No. 60747-1 | For mains voltage, PD 2 or 3 |
| Leakage Current | ≤ 0.5 mA (Canada difference) | At 1.06 × rated voltage |
| Maximum tc | As declared by manufacturer | Thermal endurance at tc + 10 K |
| Mechanical Impact | 0.5 J (portable), 0.35 J (fixed) | IEC 60068-2-75 |
| Marking Permanence | No illegibility after rubbing / water | CSA specific variation |
Warning: Canadian national differences often impose stricter leakage current limits and additional environmental conditioning (e.g., –30°C cold start test) compared to the international IEC version. Always consult the latest edition of CAN/CSA C22.2 No. 62031-13 and any applicable National Differences document.
Implementation Highlights and Testing Considerations
Design for Canada
When designing an LED module for CSA certification, pay special attention to:
- Creepage distance – often require at least 3.2 mm for secondary circuits compared to 2.5 mm in IEC
- Wire sizing – Canadian Electrical Code (CSA C22.1) may mandate larger gauge (e.g., 18 AWG vs 20 AWG)
- Ambient temperature range – the standard typically tests from –25°C to +40°C, but for outdoor use –40°C may be required
- Flammability – PCB and insulating parts must meet V-1 or better per CSA C22.2 No. 0.17
Testing Sequence
Certification testing typically follows these steps:
- Visual inspection and marking check
- Normal temperature rise test (measure tc and component temperatures)
- Dielectric strength and leakage current measurements
- Abnormal conditions: short circuit of LEDs, failure of control gear components
- Mechanical tests (pulling, torque, impact, static load)
- Environmental tests (damp heat, cold start, salt fog if applicable)
- Insulation resistance and hi‑pot after humidity
Best Practice: Engage a recognized certification body (e.g., CSA, UL, Intertek) early in the design phase. A pre‑compliance review can identify Canadian‑specific gaps before formal testing, saving time and cost.
Compliance and Certification Notes
Market Acceptance
LED modules certified to CAN/CSA C22.2 No. 62031-13 are accepted across all Canadian provinces and territories. The CSA mark (or equivalent recognized mark) is required for products sold under the Canadian Electrical Code (CE Code, Part I). This standard is harmonized with IEC 62031 to facilitate international trade while addressing Canadian safety and environmental conditions.
National Differences (NDs)
The Canadian adoption includes several modifications from IEC 62031. Notable examples:
- ND 2: Lower leakage current limit (0.5 mA vs 1.0 mA)
- ND 6: More stringent mechanical tests for plug‑in modules
- ND 8: Requirement for an insulating barrier between primary and secondary circuits for Class II modules
- ND 11: Additional marking requirements for the rated tc and IP rating
Important: The National Differences are mandatory. Ignoring them can lead to product rejection at certification or even recall. Always obtain the full Canadian standard document, not only the IEC version.
Factory Inspection and Quality
Certification requires initial factory inspection (IF) and periodic follow‑up inspections (FUP) to ensure ongoing compliance. The manufacturer must maintain documented production‑line testing for dielectric strength, grounding continuity, and marking.
Frequently Asked Questions
Q: Does CAN/CSA C22.2 No. 62031-13 cover LED modules with integrated control gear (drivers)?
A: Yes, the standard covers both integral LED modules (with built‑in control gear) and non‑integral modules. However, when the module is part of a luminaire, the luminaire standard (e.g., CSA C22.2 No. 250.13) may also apply, and the module must be evaluated accordingly.

Q: Is photobiological safety (blue light hazard) included in this standard?
A: The standard references IEC/CSA 62471 for photobiological risk assessment. It is not explicitly tested inside 62031-13, but compliance with the risk group classification (Risk Group 1 or exempt) is typically required by the luminaire standard and by Canadian authorities. Many certification bodies include this evaluation anyway.

Q: What is the difference between IEC 62031 and CAN/CSA C22.2 No. 62031-13?
A: The CSA version includes Canadian National Differences that account for the Canadian Electrical Code, different environmental conditions, and historically accepted safety margins. Examples include tighter leakage current limits, additional mechanical tests, and modified creepage/clearance values. The structure and core requirements remain harmonized.
