Safety Requirements for Wireless Communication Equipment: An In-Depth Look at CSA C22.2 No. 198.2-15 (2017)
Understanding the Canadian Standard for the Safety of Two-Way Radio, Cellular, and Wireless Data Systems
Scope and Application of CSA C22.2 No. 198.2-15
CSA C22.2 No. 198.2-15 (2017) forms part of the Canadian Electrical Code, Part II, and establishes safety requirements for wireless communication equipment operating in the frequency range from 25 MHz to 6 GHz. This standard applies to a wide array of two‑way radio equipment, cellular terminals, wireless data devices, and related accessories intended for indoor, outdoor, and portable use.
The standard covers equipment designed for installation in accordance with the Canadian Electrical Code, Part I (CSA C22.1) and is intended to reduce risks of fire, electric shock, mechanical injury, and harmful RF exposure. It does not cover fixed point‑to‑point links, broadcasting transmitters, or equipment intended solely for laboratory use.
Key Application: Manufacturers seeking CSA certification for portable radios, mobile two‑way transceivers, cellular handsets, and wireless module components must comply with this standard.
Technical Requirements for Equipment Safety
Electrical Safety and Insulation
All equipment connected to a main power source must meet stringent insulation and clearance requirements. The standard mandates:
- Minimum creepage distances and clearances based on working voltage and insulating material group (following Appendix A of CSA C22.2 No. 0.4).
- Double or reinforced insulation between accessible parts and hazardous live circuits.
- Overvoltage protection for equipment with a rated voltage exceeding 48 V DC or 50 V RMS AC.
Mechanical and Environmental Durability
Equipment intended for portable or mobile use must pass impact, drop, and vibration tests. The standard specifies:
| Test | Criteria | Acceptance |
|---|---|---|
| Drop test (1.2 m on concrete) | 1 drop on each face, edge, corner | No rupture, no hazardous live part exposure |
| Impact test (spring‑hammer 0.5 J) | 3 impacts per face | No insulation breakdown, no fire hazard |
| Vibration (sinusoidal, 10‑55 Hz) | Amplitude 0.35 mm, 10 cycles per axis | No loosening of parts, no intermittent malfunction |
RF Exposure Limits
The standard references Health Canada’s Safety Code 6 (ICNIRP equivalent) for specific absorption rate (SAR) limits. Portable devices operated at a distance of ≤ 20 cm from the body must demonstrate a SAR peak spatial average of ≤ 1.6 W/kg over 1 g tissue (head and trunk) and ≤ 4.0 W/kg over 10 g tissue (limbs).
Design Consideration: Devices with multiple antennas or simultaneous transmissions may require additional simulation or testing to show composite SAR compliance.
Implementation Highlights for Designers
Marking and Instructions
Each device must be permanently marked with:
- Rated current, voltage, and frequency (if AC powered).
- Manufacturer’s name or trade‑mark and model identifier.
- Canadian certification mark (e.g., CSA Monogram).
User and installation instructions must include RF exposure warnings, battery handling precautions, and any required separation distances.
Battery and Charger Systems
Rechargeable battery packs and charging cradles must comply with additional requirements from CSA C22.2 No. 0.15 and IEC 62133. Tests for overcharge, short‑circuit, reverse polarity, and thermal runaway are mandatory.
Good Practice: Integrating a gas gauge and temperature cutoff in battery packs helps meet the abnormal‑charge and forced‑discharge tests.
Compliance Notes and Certification Process
CSA Group performs certification under the C22.2 umbrella. The typical process involves:
- Application and pre‑evaluation – Provide construction details, schematics, bill of materials.
- Testing agency review – Full testing according to tables 1‑15 of the standard.
- Factory inspection – Initial and periodic follow‑up audits are required.
- Certification and mark – Upon passing, the CSA monogram is authorized for the product.
| Stage | Typical Duration | Deliverables |
|---|---|---|
| Application | 1‑2 weeks | Product documentation |
| Safety testing | 4‑8 weeks | Test report |
| Factory inspection | 2‑3 days | Inspection report |
| Certification award | 1‑2 weeks | Certificate of compliance |
Critical: Changes in RF power amplifiers, antennas, or battery chemistry after certification may require a new evaluation – always consult your certification body before modding an approved device.
Frequently Asked Questions
Q: Does CSA C22.2 No. 198.2-15 apply to wireless modules intended for integration into other equipment?
A: Yes, if the module is a complete radio with an RF transmitter and its own power management circuit. The integrator must ensure the final assembly also complies with the standard for enclosure, marking, and RF exposure.
A: Yes, if the module is a complete radio with an RF transmitter and its own power management circuit. The integrator must ensure the final assembly also complies with the standard for enclosure, marking, and RF exposure.
Q: Are there specific requirements for outdoor antennas?
A: While the standard covers the transmitting equipment itself, permanently installed outdoor antennas must meet CSA C22.2 No. 0.12 for environmental withstand and grounding. The equipment standard mandates lightning suppression for antenna ports if the system is used outside.

Q: How are simultaneous RF transmissions handled for SAR compliance?
A: The standard requires either combined SAR testing or summation of SAR values from each transmitter. If the sum exceeds the limit, additional measurements or simulations using approved computational methods (e.g., FDTD) must be performed.

Q: Can an IEC 62368-1 report be re-used for part of the CSA assessment?
A: Yes, provided the differences between the IEC edition and the CSA C22.2 requirements (including Canadian deviations) are covered. The certification body will typically accept IECEE CB reports with a national deviation review.
