Understanding CAN CSA E60335-2-65-11 (2016): Safety Requirements for Air-Cleaning Appliances
A comprehensive guide to the Canadian adoption of IEC 60335-2-65 for air-cleaning appliances
Scope and Application
CAN CSA E60335-2-65-11 (2016) is the Canadian adoption of IEC 60335-2-65, covering the safety of household and similar electrical air-cleaning appliances. This standard applies to appliances intended for filtering, cleaning, or purifying air in residential and commercial spaces, including portable units, ceiling-mounted units, and those integrated into HVAC systems. The standard addresses electrical, mechanical, thermal, and chemical hazards, with particular emphasis on ozone generation from electrostatic types.
Key benefit: Compliance with CAN CSA E60335-2-65-11 ensures that air-cleaning appliances meet rigorous safety requirements, reducing the risk of fire, electric shock, and harmful ozone exposure for Canadian users.
Applicable Products
The standard covers a wide range of air-cleaning technologies including filter-based, electrostatic, ultraviolet, photocatalytic, and ionizing appliances. Appliances with a rated voltage not exceeding 250 V for single-phase and 480 V for polyphase are within scope. Notably, this standard does not cover appliances intended solely for industrial purposes or those designed for medical applications.
Key Technical Requirements
Ozone Emission Limits
Electrostatic and ionizing air cleaners are required to limit ozone emissions to safe levels. CAN CSA E60335-2-65-11 specifies a maximum ozone concentration of 0.050 ppm (by volume) in the ambient air when the appliance operates under normal test conditions. This limit aligns with Health Canada guidelines and protects against respiratory tract irritation.
Caution: Ozone generation is a critical safety parameter. Manufacturers must verify that their product does not exceed the limit under worst-case operating scenarios, including after prolonged use and at maximum fan speed.
Electrical Safety and Protection
The standard incorporates general safety requirements from IEC 60335-1 (adopted as CSA C22.2 No. 60335-1) and adds specific provisions for air-cleaning appliances. These include:
- Leakage current limits for electrostatic grids
- High-voltage component insulation and creepage distances
- Protection against access to live parts, especially in electrostatic units
- Overload and overheating protection for fans and motors
Mechanical Hazards
Moving parts such as fans and filters must be guarded to prevent injury. For appliances with exposed UV lamps, the standard requires shielding to prevent radiation exposure. Filters must be secured to prevent unintended ejection during operation.
Performance and Test Conditions
| Parameter | Requirement / Limit | Test Method Reference |
|---|---|---|
| Ozone concentration | ≤ 0.050 ppm | Annex AA (normative) |
| Leakage current (electrostatic) | ≤ 0.25 mA | IEC 60335-1, Clause 13 |
| Touch current | ≤ 0.5 mA for portable | IEC 60335-1, Clause 16 |
| High-voltage grid creepage | ≥ 8 mm (if > 2 kV peak) | Annex BB |
| Filter retention force | ≥ 50 N | Clause 22.102 |
Tip: Test for ozone should be conducted in a well-defined test chamber with controlled temperature and humidity to ensure reproducible results. Consider using certified test laboratories with experience in IEC 60335-2-65 evaluation.
Implementation Highlights for the Canadian Market
CAN CSA E60335-2-65-11 (2016) is harmonized with the US standard UL 867 in several aspects but retains Canadian-specific deviations. Key differences include:
- Ozone limit is more stringent (0.050 ppm vs. 0.050 ppm in US, but Canadian test procedures may differ)
- Requirements for bilingual (English/French) safety markings and instructions
- Adoption of Canadian Electrical Code (CEC) Part I wiring rules
- Additional marking for appliances intended for use in wet locations (e.g., bathrooms)
Manufacturers entering the Canadian market must ensure that their products bear the appropriate CSA mark or recognized certification mark for compliance with this standard. Importer responsibilities include maintaining technical documentation and providing instructions in both official languages.
Important: Non-compliance with CAN CSA E60335-2-65-11 can lead to market withdrawal, fines, or liability issues. Products without CSA certification may be rejected by Canadian distributors or retailers.
Compliance and Certification Notes
To demonstrate compliance, manufacturers should follow the certification process outlined by CSA Group or other accredited certification bodies (e.g., QPS, Intertek, TÜV SÜD). The process typically includes:
- Application and technical documentation review
- Product testing in an accredited laboratory
- Factory inspection and follow-up audits
- Labeling and marking verification
The standard underwent revisions in 2016 to incorporate updated requirements for newer technologies such as photocatalytic and plasma air cleaners. Any amendments should be reviewed to ensure continued compliance. All relevant clauses of the base standard (IEC 60335-1) together with this Part 2-65 must be applied.
Recommendation: Engage with a certification body early in the product development cycle. Having pre-compliance testing and design reviews can significantly reduce time-to-market.
Frequently Asked Questions
Q: Does CAN CSA E60335-2-65-11 (2016) apply to commercial air purifiers used in offices?
A: Yes, the standard covers household and similar commercial appliances. Units intended for ordinary commercial use (e.g., small offices, retail spaces) are within scope provided they are not rated for heavy industrial applications.

Q: What is the maximum ozone level allowed by this standard?
A: The limit is 0.050 parts per million (ppm) by volume. This is measured in a 30 m³ test chamber under specific conditions defined in Annex AA. Some electrostatic devices may require additional control circuitry to remain below this threshold.

Q: Is there a transition period if a new revision of the standard is released?
A: Generally, when a new edition is published, a transition period of one to three years is provided by certification bodies. However, it is advisable to monitor CSA Group announcements and begin compliance work promptly.

Q: Can a product certified to IEC 60335-2-65 be marketed in Canada without additional testing?
A: Not automatically. Canadian adoption includes national deviations, so a product compliant with the international standard must still be evaluated for the specific CSA requirements, particularly ozone testing and bilingual labeling.
