Understanding CAN CSA C22.2 No. 60335-2-45-14: Safety for Portable Heating Tools in Canada
Comprehensive guide to the Canadian adoption of IEC 60335-2-45 for portable heating tools, including technical requirements, implementation highlights, and compliance notes.
CAN CSA C22.2 No. 60335-2-45-14 (2018) is the Canadian adoption of the international standard IEC 60335-2-45, which specifies safety requirements for portable heating tools and similar appliances for household and commercial use. This standard is part of the Canadian Electrical Code (CE Code) Part II series (C22.2) and incorporates both the international requirements and the specific deviations necessary for compliance with Canadian electrical safety regulations. This article provides an in-depth overview of the standard’s scope, key technical requirements, implementation considerations, and certification pathways, with a focus on helping manufacturers, engineers, and compliance professionals navigate this regulatory framework.
Scope and Application
This standard applies to portable heating tools rated voltage not more than 250 V for single-phase appliances and 480 V for other appliances. Typical covered appliances include:
- Soldering irons, soldering guns, and desoldering tools
- Glue guns and hot-melt adhesive applicators
- Heat guns for stripping paint, shrinking tubing, and thawing
- Portable immersion heaters and similar devices
- Deseaming irons and other electrically heated hand tools
The standard covers the safety of these appliances under normal and abnormal operating conditions, including electrical, mechanical, thermal, and fire hazards. It also applies to appliances that are not intended for normal household use but may be used in workshops, light industry, and by commercial operators, as long as they fall within the definition of portable heating tools.
Tip: Manufacturers of multi-functional tools (e.g., heat gun with soldering attachment) should verify that each operating mode is covered separately under the relevant part of the IEC 60335 series. CAN CSA C22.2 No. 60335-2-45-14 specifically addresses heating functions; additional requirements from other parts may apply.
Technical Requirements
Electrical Safety and Marking
All appliances must withstand the dielectric strength test (hi-pot) and leakage current limits specified in the standard. The insulation system must be suitable for the temperatures expected in normal use. For portable heating tools, the standard requires:
- Minimum clearances and creepage distances based on rated voltage and pollution degree.
- Protection against access to live parts (IP code or enclosure requirements).
- Durable marking of rated voltage, frequency, power input, and the manufacturer’s name or trademark.
- Markings in both English and French, as required by Canadian regulations.
Heating and Surface Temperature Limits
The standard limits the temperature of accessible surfaces to prevent burns. For handles and knobs held continuously, the maximum allowable temperature rise is 60 K for metallic parts and 75 K for plastic or non-metallic parts. For the heating element tip or nozzle, where the function requires high temperature, no limit is imposed but the appliance must be designed so that the temperature does not cause fire hazards to surrounding materials.
| Parameter | Requirement | Test Condition |
|---|---|---|
| Input power tolerance | ±10% of rated input at rated voltage | Stabilized on-load |
| Leakage current | ≤ 0.75 mA for portable tools | At rated voltage, normal operation |
| Dielectric strength (basic insulation) | 1,250 V for 60 s | Between live parts and accessible metal |
| Maximum handle temperature rise | 60 K (metal), 75 K (plastic) | After 30 min continuous operation |
| Stability and mechanical hazard | No overturning on 10° tilt; no sharp edges | As per IEC 60335-1 |
Important: The temperature rise limits for portable heating tools are generally lower than those for stationary appliances, reflecting the need for safe handheld operation. Manufacturers should perform thorough thermocouple measurements during type testing.
Implementation Highlights
The Canadian adoption introduces several deviations from the international base standard IEC 60335-2-45:2002 (including Amendments 1 and 2). Notable differences include:
- Supply cord and plug: Tools must be provided with a Canadian standard cord set (e.g., C22.2 No. 49 or No. 21) and a parallel‑blade attachment plug (NEMA 1-15P or 5-15P) rated at 125 V / 15 A. The length of the cord must comply with Canadian requirements.
- Bilingual markings: All safety and instruction markings must be in both English and French, with specific wording for warnings.
- Grounding: For Class I tools, the grounding terminal must be clearly identified and comply with CSA requirements for bonding conductors.
- Environmental conditions: The standard includes additional tests for cold impact and withstand temperature for Canadian climate considerations.
- Component approval: Certain components (e.g., switches, thermostats) must be recognized to applicable CSA standards.
Compliance Benefit: Early incorporation of CSA‑specific deviations in the design phase significantly reduces the time and cost of certification, as there are fewer non‑conformities during the formal evaluation.
Compliance and Certification Notes
To demonstrate conformity with CAN CSA C22.2 No. 60335-2-45-14, manufacturers must submit their appliances for evaluation by a recognized certification body, such as CSA Group, UL (cUL), or Intertek (cETL). The process typically involves:
- Review of the technical file (drawings, bill of materials, and test data).
- Type testing of the appliance to all applicable clauses.
- Factory inspection to ensure consistent production quality (for initial certification and periodic follow‑up).
Once certified, the product may bear the CSA mark or an accepted equivalent mark (e.g., cUL, cETL) as evidence of compliance with the Canadian Electrical Code Part II. This mark is recognized nationally across Canada by provincial and territorial authorities having jurisdiction.
Warning: Selling a portable heating tool in Canada without a valid CSA (or equivalent) safety certification is illegal under most provincial electrical safety acts. Penalties can include product seizure, fines, and market withdrawal orders.
It is also worth noting that the standard is currently under periodic review. As of 2026, the 2018 edition remains current, but manufacturers should monitor the CSA Group’s update cycle for any proposed amendments or revisions that may impact design or testing.
Frequently Asked Questions
Q: What specific tools are covered by CAN CSA C22.2 No. 60335-2-45-14?
A: The standard covers portable electric heating tools such as soldering irons, solder/desoldering guns, hot‑melt glue guns, paint‑stripping heat guns, and similar handheld devices. For tools with additional functions (e.g., a soldering/desoldering station with a temperature‑controlled base), both the handpiece and the control unit are covered under the relevant clauses.

Q: What is the main difference between this Canadian standard and the international IEC 60335‑2‑45?
A: While the technical safety requirements are largely harmonized, the Canadian adoption imposes specific deviations: mandatory bilingual labeling, a Canadian‑specified plug and cord set, enhanced grounding requirements, and additional mechanical impact tests. These differences must be fully addressed to achieve CSA certification.

Q: Does the standard apply to appliances intended for industrial use only?
A: Yes. The standard covers portable heating tools for household, commercial, and light industrial use. However, tools designed exclusively for heavy‑duty industrial processes (e.g., industrial heat guns built into machinery) may fall under other CSA C22.2 or safety standards. Manufacturers should consult with a certification body to confirm scope.

Q: How long does the certification process typically take?
A: For a standard product with no major deviations, the testing and review can take 8–16 weeks, depending on the workload of the certification body and the complexity of the appliance. Factory inspection visits are scheduled separately. It is advisable to begin the process early in the product development cycle.
