CSA C22.2 No. 745-2-30-95 (R2018): Safety Requirements for Electric Hammers – A Guide to Compliance and Implementation
Understanding the scope, technical requirements, and compliance framework for hand-held motor-operated electric hammers under Canadian standards
Scope of CSA C22.2 No. 745-2-30-95 (R2018)
CSA C22.2 No. 745-2-30-95 (R2018) is the Canadian adoption of IEC 60745-2-30:1995, with national deviations to align with the Canadian Electrical Code (CE Code, CSA C22.1). This standard applies to hand-held motor-operated electric hammers, including rotary hammers, chipping hammers, demolition hammers, and similar impact tools intended for professional and domestic use. It covers tools rated at not more than 250 V single-phase or 480 V three-phase, and it establishes safety requirements for construction, mechanical strength, thermal protection, and vibration exposure.
Tip: Although originally published in 1995, the 2018 reaffirmation confirms that the technical provisions remain current for Canadian certification. However, manufacturers should check for amendments or supplements issued after 2018 that may affect compliance.
Technical Requirements
Protection Against Mechanical Hazards
The standard mandates that all tools must be equipped with guards that prevent accidental contact with moving parts (e.g., chisel, drill bit, hammer mechanism). Guards must be non-removable except with the use of tools. For chipping hammers, a locking device must secure the tool accessory during operation.
Electrical Safety and Insulation
Double insulation (Class II construction) is required unless the tool is intended for use with a grounding conductor (Class I). Leakage current limits are specified under normal and fault conditions, and dielectric strength tests must be performed at 1250 V for Class II and 1500 V for Class I. All insulation materials must withstand thermal ageing tests.
Vibration Emission Control
One of the most critical technical aspects is the limitation of hand-arm vibration. The standard references ISO 5349 for measurement methodology. The declared vibration emission value (ahv) must not exceed the limits specified in the standard for different hammer types. Manufacturers must perform vibration tests on at least three samples, and the upper limit of the measured values becomes the declared value.
Warning: High vibration levels are a known health risk. Compliance with CSA C22.2 No. 745-2-30-95 (R2018) is not a substitute for proper risk assessment per CAN/CSA-Z1002. Always supplement with administrative controls such as rest periods and work scheduling.
Thermal Protection and Overload
Tools must incorporate thermal cut‑outs or current limiters that prevent the motor from exceeding its temperature class rating (typically Class A or E). The standard specifies a temperature rise test at rated load: the winding temperature rise must not exceed 85 K (Class A) or 100 K (Class E) after 30 minutes of continuous operation.
Mechanical Strength and Drop Test
The tool must survive a 1 m drop onto a concrete surface without impairing safety. After the drop test, the tool must still pass dielectric and leakage current tests. This requirement ensures robustness for jobsite handling.
| Parameter | Requirement | Test Condition |
|---|---|---|
| Leakage current (Class II) | ≤ 0.5 mA | At rated voltage, no load |
| Dielectric strength (Class II) | 1250 V, 1 min, no breakdown | Between live parts and accessible metal |
| Vibration emission (rotary hammers) | ahv ≤ 20 m/s² | Per ISO 5349, three axes |
| Temperature rise, winding | ≤ 85 K (Class A) / ≤ 100 K (Class E) | 30 min at rated load |
| Drop test height | 1.0 m onto concrete | Three orientations, tool switched off |
Implementation Highlights for Manufacturers
Design Considerations
To meet the vibration limits, designers should incorporate vibration damping handles, mass balancing, and reduced impact frequency at no load. Compliance with the guard requirements often demands a combination of fixed and adjustable guards, particularly on demolition hammers where chisel position changes frequently.
Quality Control in Production
The standard requires periodic verification of insulation resistance (≥ 7 MΩ after humidification) and dielectric strength. Manufacturers must implement a routine test program for 100% of production: a flash test at 1 000 V for 1 second, plus a ground continuity check for Class I tools.
Marking and Instructions
Every tool must bear the CSA mark or a recognized certification mark, along with the model number, serial number, voltage, frequency, input power (in W or A), and the double insulation symbol ( ∏ ) for Class II. Instruction manuals must include vibration and noise emission values, warnings about residual risks, and details on essential maintenance intervals (e.g., brush replacement every 100 h).
Compliance Notes for Certifiers and Users
Certification Process in Canada
To obtain CSA certification, the manufacturer must submit a test report from a CSA accredited laboratory. The report must confirm compliance with all clauses of C22.2 No. 745-2-30-95 (R2018) and with the applicable requirements of the base standard C22.2 No. 745-1 (IEC 60745-1). A factory inspection is required to verify production line testing and quality systems.
Success: Products certified to this standard are accepted across all Canadian provinces and territories under the CE Code. Certification also eases market access via mutual recognition with UL and other North American schemes.
User Safety and Maintenance
Users of CSA-certified hammers must follow the manufacturer’s instructions, especially regarding:
- Use of vibration‑dampening gloves and hearing protection.
- Periodic inspection of the power cord (must be a CSA-certified cord type SJTW or equivalent).
- Replacement of carbon brushes only with original parts to maintain compliance.
- Never operating the tool without its proper guard assembly.
Danger: Modifying a certified hammer (e.g., removing guards, using non‑approved accessories, bypassing the trigger lock‑off) voids the CSA certification and may lead to serious injury or fire. Always use genuine replacement parts.
Frequently Asked Questions
Q: Does CSA C22.2 No. 745-2-30-95 (R2018) apply to battery‑powered hammers?
A: Yes, the standard covers both corded and battery‑powered (cordless) hand‑held electric hammers, provided they have a motor and produce an impact action. For battery‑powered tools, additional requirements for battery packs and chargers from other CSA standards (e.g., C22.2 No. 0) must also be considered.

Q: Is there a new edition expected to replace this 1995 version?
A: CSA plans to adopt a future IEC edition (likely based on IEC 62841‑2‑6) which will replace the entire 60745 series. However, as of 2025‑2026, the 2018 reaffirmation remains the active national standard. Manufacturers transitioning to the new standard should begin early compliance work.

Q: What are the main differences between CSA C22.2 No. 745‑2‑30 and the US UL 60745‑2‑30?
A: The technical requirements are harmonized (both adopt IEC 60745‑2‑30), but Canadian deviations (DRs) exist for voltage ratings, cord types (CSA‑certified SJTW vs. UL‑listed SJT), and marking language (English/French). Always request the CSA edition with DRs when testing for the Canadian market.

Q: Do I need to test vibration for each tool model separately?
A: Yes, vibration emission values must be determined for each model family. However, if the mechanical design (mass, handle, impact mechanism) is identical, the highest measured value from one representative can be declared. Still, the standard allows only 0.5 m/s² tolerance between models; otherwise, each requires separate testing.
