Understanding CSA C22.2 No. 60745‑2‑21‑05 (2018): Safety Requirements for Hand‑Held Motor‑Operated Cutting Tools
A comprehensive guide to the Canadian adoption of IEC 60745‑2‑21 for the safety of cutting and machining tools
Scope and Application
CSA C22.2 No. 60745‑2‑21‑05 (2018) is the Canadian national adoption of IEC 60745‑2‑21:2010 with specific national differences. It applies to hand‑held motor‑operated electric tools intended for cutting or machining materials, such as saws, shears, nibblers, and similar tools. These tools are rated for voltages not exceeding 250 V for single‑phase AC/DC or 480 V for three‑phase AC. The standard covers both corded and battery‑operated tools, but not those used with separate transformers or converters.
The purpose is to reduce the risk of injury to operators and other persons from mechanical, electrical, thermal, and other hazards that could arise during normal use or reasonably foreseeable misuse. It complements the general safety requirements of the broader CSA C22.2 standard series (Canadian Electrical Code, Part 2).
Scope note: Tools covered include circular saws, jigsaws, reciprocating saws, shears, nibblers, and similar cutting or machining devices. The standard does not apply to tools used in fixed or stationary installations, nor to tools intended primarily for woodworking or metalworking that are not hand‑held.
Technical Requirements and Testing
Mechanical Guarding
Cutting tools must be equipped with protective guards that cover the blade or cutting element during idle and during operation. For tools with rotating blades (e.g., circular saws), a retract‑type lower guard must automatically spring back into place after a cut. Stationary guards must prevent accidental contact with the moving cutting element under normal working positions.
Electrical and Thermal Safety
All electrical components must be protected against ingress of dust and moisture according to at least IP20. Thermal overload protection (e.g., resettable thermal cut‑out) is required to prevent overheating under sustained load. Insulation resistance must not fall below 5 MΩ under high‑voltage test conditions.
Mechanical Strength and Handling
Tools must withstand a 1 m drop onto a concrete floor without sustaining damage that could affect safety. Handles must be designed to provide a secure grip and to limit surface temperatures rise to not more than 30 K above ambient during continuous operation.
Critical test: Vibration emission is measured according to ISO 5349. Acceleration values for tools in this category are typically evaluated at the main handle; the declared emission value must not exceed 10 m/s² unless otherwise justified by the manufacturer.
| Test | Requirement | Typical Acceptance Criteria |
|---|---|---|
| Guard impact resistance (drop test on guard) | Guard must not fracture or detach | Drop mass of 1 kg from 1 m height |
| Switch endurance | 50 000 cycles for trigger, 10 000 for locking button | No electrical failure or mechanical seizure |
| Voltage withstand | 1 250 V for 1 minute (basic insulation) | No breakdown or flashover |
| Thermal cut‑out withstand | 100 operations at rated current | Cut‑out must reset, no permanent damage |
Implementation and Compliance
Manufacturers seeking CSA certification for a cutting tool under this standard must submit representative samples along with a Technical Construction File (TCF). The certification process includes a type‑test evaluation against all applicable clauses, followed by factory inspections to verify ongoing quality control. Products that successfully meet the requirements are authorized to bear the CSA mark.
National Differences from IEC 60745‑2‑21
The CSA standard includes Canadian‑specific deviations such as:
- Mandatory use of locking ON switches for tools that can generate kickback (e.g., reciprocating saws).
- Increased creepage and clearance distances for use in Canadian ambient conditions.
- Marking requirements for bilingual (English/French) safety instructions.
Compliance pathway: For products already certified to the latest IEC edition, a gap analysis against the Canadian deviations is often sufficient to obtain full CSA certification. Many recognized test houses can perform the additional tests.
Compliance Notes and Best Practices
End‑users and specifiers in Canada must ensure that hand‑held cutting tools purchased after 2018 comply with the 2018 edition. Transition periods may have allowed earlier compliance to the 2009 edition, but as of 2026, the 2018 edition is the sole normative requirement for most power tools.
Attention: Tools that are not marked with a valid CSA certification number or that display a certification mark for a different scope (e.g., industrial only) may not meet the essential safety requirements for consumer use. Always verify the certification mark matches the standard number.
Maintenance of Certification
CSA normally audits production facilities twice per year. Manufacturers must maintain records of changes that could affect conformity (e.g., design modifications, supplier changes). Failure to notify CSA may result in suspension of certification.
Q: Does CSA C22.2 No. 60745‑2‑21‑05 cover battery‑operated tools?
A: Yes, it applies to both corded and battery‑operated hand‑held tools. However, battery packs themselves are covered under separate standards (e.g., CSA C22.2 No. 62133).

Q: What is the relationship between this standard and the Canadian Electrical Code (CE Code)?
A: CSA C22.2 standards form the Part 2 series of the CE Code, covering equipment safety. Compliance with this standard is one way to meet the equipment‑safety requirements of the CE Code, Part 1.

Q: Can a tool bearing the IEC‑CB report be directly accepted in Canada?
A: Not automatically. The manufacturer must demonstrate that the tool meets the additional national differences listed in Annex DB of the CSA standard. A CB test report covering the IEC edition serves as a strong foundation, but supplementary testing for the Canadian deviations is usually required.
