Understanding CAN CSA C22.2 No. 60745-2-6-04 (2018): Safety Requirements for Hand-Held Electric Hammers
A comprehensive guide to the Canadian adoption of the IEC standard for hammers, covering scope, technical mandates, and compliance strategies.
Introduction and Scope
Hand-held electric hammers—including rotary hammers, demolition hammers, and combination hammer-drills—are vital tools in construction, demolition, and renovation. Their high impact energy and rotating mechanisms introduce unique safety hazards. CAN CSA C22.2 No. 60745-2-6-04 (2018) is the Canadian national adoption of IEC 60745-2-6, which specifies particular safety requirements for these tools. This article provides a detailed analysis of the standard’s scope, technical requirements, implementation strategies, and compliance obligations.
The standard applies to motor-operated or magnetically driven hammers rated for voltages up to 250 V for single-phase tools and 480 V for three-phase tools. It covers all hand-held models that hammer, including those with rotary action. Tools intended for use in explosive atmospheres or medical applications are excluded. The standard addresses hazards specific to hammer action, such as mechanical shock, vibration, dust emission, chuck projection, and unintended start-up.
Technical Requirements
Electrical Safety
CAN CSA C22.2 No. 60745-2-6-04 (2018) builds upon the general requirements of IEC 60745-1. Additional electrical mandates include reinforced insulation for high-voltage circuits, specific creepage and clearance distances, and enhanced ingress protection (IP) to resist conductive dust typical of drilling and chiseling. The standard also requires overload protection and thermal cut-offs that reset automatically or manually according to tool type.
Mechanical Safety
Enclosures must withstand a 1-meter drop onto concrete without exposing live parts or impairing safety. Guards for chucks and bits must be securely retained; the standard requires that any removable guard require a tool for removal. Vibration dampening systems are not mandatory but are encouraged to reduce the declared vibration emission value. The tool must have a means to prevent accidental start-up, such as a two-step switch or a lock-off mechanism.
Vibration and Dust
Manufacturers must determine and declare the vibration emission value in accordance with Annex D of IEC 60745-2-6, using standardized measurement positions and work cycles. The standard also requires that tools designed for concrete drilling be equipped with a dust extraction outlet. Marking must include the vibration emission level in the instruction manual and on the tool if specified.
| Parameter | Requirement (from CSA C22.2 No. 60745-2-6-04) | Verification Method |
|---|---|---|
| Rated Voltage | ≤ 250 V single-phase; ≤ 480 V three-phase | Design specification |
| Enclosure Strength | 1 m drop onto concrete; no damage impairing safety | Drop test per IEC 60745-1 |
| Guard Retention | Tool required for guard removal; guard must be retained | Visual inspection + tool test |
| Vibration Emission Value | Declared in m/s² based on specified test cycle | Test per Annex D of IEC 60745-2-6 |
| Dust Extraction Outlet | Mandatory for tools intended for concrete work | Design check |
| Thermal Protection | Overload protection for motor, reset type defined | Abnormal operation test |
| Marking (Dual Language) | Requirements in English and French; vibration declaration | Label and manual review |
Implementation Highlights
Design Considerations
Tip: Integrate vibration dampening features (e.g., rubber isolators, counterbalanced mechanisms) early in the design to minimize the declared vibration value, which directly impacts user perception and marketability.
Manufacturers should adopt dual insulation or reinforced insulation to meet shock protection without grounding, simplifying export compliance. The mandatory dust extraction outlet must be designed to connect to a standard industrial vacuum; dust nozzles must not be sharp or cause injury.
Testing and Certification
Certification for the Canadian market requires testing by an accredited testing laboratory recognized by the Standards Council of Canada (SCC) or a CB test laboratory in the IECEE system. The standard includes Canadian deviations, such as ambient temperature testing at 25°C instead of 23°C and specific supply cord requirements (e.g., SJT type with Canadian plug).
Warning: A common non-compliance is failing the chuck guard retention test. Ensure that the guard cannot be removed without active use of a tool (screwdriver, spanner).
Compliance Notes
Compliance with CAN CSA C22.2 No. 60745-2-6-04 (2018) is mandatory for hammers sold or used in Canada under provincial electrical safety regulations (e.g., Ontario Regulation 438/10). The standard is referenced in the Canadian Electrical Code, Part II (CSA C22.2 No. 0). Manufacturers exporting to Canada must ensure their products meet this national adoption, which includes additional Canadian deviations from the IEC base. Periodic audit testing is recommended; non-compliance can lead to product recalls, fines, or loss of certification.
Success: Tools fully compliant with this standard often gain faster market acceptance in Canada and serve as a baseline for meeting other national adoptions of IEC 60745-2-6.
Danger: Ignoring the 1-meter drop test requirement can result in enclosure fracture during use, leading to serious injury or death. Never skip this mechanical test.
Frequently Asked Questions
Q: What is the difference between CAN CSA C22.2 No. 60745-2-6-04 (2018) and IEC 60745-2-6?
A: The Canadian adoption includes national deviations such as testing at 25°C instead of 23°C, mandatory bilingual marking (English/French), specific supply cord requirements (e.g., Canadian plugs and SJT cordage), and modified dust extraction outlet dimensions for compatibility with Canadian vacuum systems.

Q: Which tools are covered under this standard?
A: It covers all hand-held electric hammers: rotary hammers, demolition hammers, combination hammer-drills, and similar tools with hammer mechanism. It excludes reciprocating saws (covered by ISO/TR 11688-1) and impact wrenches (IEC 60745-2-2).

Q: Is compliance mandatory in Canada?
A: Yes. Most Canadian provinces require compliance with CSA standards under their electrical safety acts. Certification to this standard (e.g., CSA mark or equivalent) is typically required for legal sale and use.

Q: How does the standard address vibration hazards?
A: The standard mandates measurement and declaration of vibration emission values in m/s² according to a standardized test (Annex D of IEC 60745-2-6). Although no maximum limit is specified, the declared value must be included in the instruction manual, allowing users to assess exposure and select adequate protection.
