CAN CSA C22.2 No. 61029-2-10-06: Safety Requirements for Transportable Mixing Machines
Understanding the Canadian National Standard for Motor-Operated Electric Mixing Equipment
Scope of CAN CSA C22.2 No. 61029-2-10-06
CAN CSA C22.2 No. 61029-2-10-06 is the Canadian national adoption of IEC 61029-2-10, titled “Safety of transportable motor-operated electric tools – Part 2-10: Particular requirements for mixing machines.” Published under the Canadian Standards Association (CSA) C22.2 series of electrical equipment standards, this document specifies safety requirements and test methods for transportable electric mixing machines intended for household, commercial, or light industrial use. Common applications include mixing concrete, mortar, plaster, paints, resins, and similar materials.
The standard applies to mixing machines that are rated for single-phase or three-phase AC power up to 250 V and have a rated power input not exceeding 3 kW. Machines covered are those that can be moved from one location to another, either by built-in wheels, handles, or by manual transport, but are not hand-held. Drums, paddles, or agitators are considered part of the mixing system and fall under the scope of this standard. The document excludes stationary industrial mixers covered by other standards such as CAN/CSA-C22.2 No. 60745 series (hand-held tools) or permanently installed equipment.
Tip: CAN CSA C22.2 No. 61029-2-10-06 is harmonized with IEC 61029-2-10:2007 but includes modifications to align with Canadian electrical codes (e.g., CSA C22.1, Canadian Electrical Code) and ambient temperature assumptions typical of North American usage. Always verify the latest edition or amendment when designing for the Canadian market.
Technical Requirements
Electrical Safety
All mixing machines must comply with fundamental insulation, grounding, and leakage current requirements. The standard mandates:
| Requirement | Limit / Condition |
|---|---|
| Insulation resistance | ≥ 2 MΩ (measured at 500 V DC) |
| Dielectric strength | No breakdown during 1 min at 1250 V (basic insulation) or 2500 V (reinforced insulation) |
| Leakage current | ≤ 0.5 mA for Class II, ≤ 3.5 mA for Class I |
| Grounding | Resistance between ground terminal and any accessible metal part ≤ 0.1 Ω |
| Clearance / creepage | Per IEC 60950-1 for pollution degree 2, overvoltage category II |
In addition, the power supply cord must be oil-resistant (e.g., type SJTOW or equivalent) and include a strain relief capable of withstanding a pull force of 100 N without displacement. The cord must be at least 2 m long for plug-connected machines.
Mechanical Safeguards
Mixing machines present unique mechanical hazards due to rotating drums, agitators, and tilting mechanisms. CAN CSA C22.2 No. 61029-2-10-06 requires:
- Guarding: Openings that allow access to moving parts during normal operation must be sized so that a standard test finger (IP1X) cannot contact hazardous moving parts.
- Stability: The machine must not tip over when loaded with 1.25 times the rated mixing capacity and placed on a 10° incline.
- Manual override: A clearly marked, readily accessible stop button (red/yellow, push‑to‑stop) must be provided.
- Residual risk: The mixing drum must have a mechanical lock or position such that accidental tilting is prevented during transport or maintenance.
Danger: Entanglement in rotating mixing elements is a leading cause of serious injury. The standard mandates that all controls be designed to prevent unintentional restart after a power interruption (zero‑voltage protection) and that the operating handle or switch automatically returns to OFF when released (dead‑man control).
Thermal and Overload Protection
Motors must be protected against overheating under conditions of stalled rotor or prolonged overload. Thermal cut‑outs (auto‑reset or manual reset) must be rated to disconnect power before winding temperature exceeds 130 °C (Class B insulation) for <2 min under locked‑rotor test. Temperature rise tests are conducted at rated load; the winding temperature rise must not exceed 90 K when measured by resistance method.
Ingress Protection & Environmental Resistance
Machines intended for outdoor or wet locations must meet at least IPX4 (splash‑proof) requirements. For concrete mixers, the standard demands protection against cement dust ingress (IP5X for dust‑exposed enclosures). All external electrical enclosures must be corrosion‑resistant (e.g., powder‑coated steel, stainless steel, or high‑impact plastic).
Implementation & Testing Highlights
Manufacturers seeking CSA certification for mixing machines must submit samples for type testing at an accredited laboratory. Key tests include:
- Abnormal operation: Stall test, blocked agitator, running with unbalanced load (simulated by attaching a 5 kg mass to one paddle).
- Mechanical endurance: The tilting mechanism and switch must withstand 10,000 cycles of normal operation.
- Overload & endurance: 100 h continuous running at 110 % rated voltage and 120 % rated current.
- Marking permanence: Labels and warnings must remain legible after wiping with water, gasoline, and isopropanol.
Warning: CSA C22.2 No. 61029-2-10-06 requires that instruction manuals include a statement: “This machine is not designed to be used by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the machine by a person responsible for their safety.”
Compliance Notes
Compliance with CAN CSA C22.2 No. 61029-2-10-06 is mandatory in most Canadian provinces under provincial electrical regulations. The standard is referenced in the Canadian Electrical Code (CSA C22.1) for transportable mixing machines. Key compliance points:
- Certification must be performed by a recognized certification body (e.g., CSA, UL, ITS). Self‑declaration is not accepted for products sold in Canada.
- Any deviation from the IEC base standard due to Canadian modifications (e.g., specific supply cord colors, plug configurations) must be documented in a Compliance Annex.
- The standard is subject to periodic updates: check with CSA Group for the most current revision (the “06” suffix indicates the 2006 edition, but amendments or new editions may supersede).
- Imported machines must bear the CSA mark or equivalent (cCSAus, cUL) and be accompanied by a bilingual (English/French) manual and marking.
Success: Product designs that fully comply with CAN CSA C22.2 No. 61029-2-10-06 benefit from reduced liability, smoother market access across Canada, and alignment with major US standards (UL 61029-2-10) where similar requirements apply.
Q: Does CAN CSA C22.2 No. 61029-2-10-06 apply to hand-held beaters or immersion blenders?
A: No. The standard specifically covers transportable mixing machines, not hand-held tools. Hand-held mixers fall under CAN/CSA-C22.2 No. 60745-2-14 (electric food preparation appliances) or similar hand‑tool standards.

Q: Can a mixing machine certified to IEC 61029-2-10 be sold in Canada without additional testing?
A: Not automatically. The certification must be reviewed for Canadian deviations (e.g., supply cord requirements, ambient temperature assumptions). Additional testing for Canadian modifications is usually required, and the product must obtain a Canadian safety mark (CSA, cUL, etc.).

Q: What is the maximum capacity covered by this standard?
A: The standard does not impose a hard capacity limit, but typical machines covered range from 50 L to 200 L. Larger stationary mixers are considered industrial equipment and fall under other standards (e.g., CAN/CSA-C22.2 No. 0.4).

Q: Are there special requirements for dual‑voltage (120/240 V) mixing machines?
A: Yes. The machine must be tested at both voltage ratings, and the voltage‑change mechanism must be protected against accidental switching. A tool‑required interlock is recommended.
