CSA C22.2 No. 1335.2.14-93 (2018): Particular Requirements for Food Processors – Scope, Technical Requirements, and Compliance
A comprehensive technical overview of the Canadian safety standard for household food processors and similar kitchen appliances
Scope and Application
CSA C22.2 No. 1335.2.14-93 (2018) is part of the Canadian Standards Association (CSA) C22.2 series of safety standards for electrical equipment. This particular standard specifies the safety requirements for electric food processors intended for household and similar commercial use. It applies to appliances with a rated voltage not exceeding 250 V for single-phase and 480 V for other appliances. The scope includes food processors, blenders, mixers, juicers, graters, and similar appliances that process food by rotating cutting tools.
The standard is harmonized with IEC 60335-2-14 (Ed. 5.2) with Canadian deviations. It covers both stand-alone food processors and attachments for multi-function appliances. The standard addresses normal use as well as reasonably foreseeable misuse by untrained users in a household environment.
Scope Note: The standard does not cover appliances intended exclusively for commercial or industrial food processing, appliances for professional kitchen use, or appliances that are part of larger processing systems. For those, reference should be made to other applicable CSA C22.2 standards or the CSA SPE-7000 series.
Technical Requirements
CSA C22.2 No. 1335.2.14-93 (2018) outlines detailed technical requirements to ensure the safety of food processors under normal and abnormal conditions. These include mechanical, electrical, thermal, and material safety aspects.
Key Technical Specifications
| Requirement Category | Specification | Test Conditions |
|---|---|---|
| Protection against contact with moving parts | Intermeshed or self-closing lids; interlock switches that disconnect power if lid is opened; maximum opening gap ≤ 4 mm | Accessibility probe in accordance with IEC 61032 |
| Stability | Appliance must not tilt more than 10° on a 15° inclined plane | With maximum load; lid open and closed |
| Mechanical strength | Blade assembly must withstand force of 50 N applied without permanent deformation | Blade locked; force applied in most unfavorable direction |
| Thermal protection | Motor temperature rise ≤ 90 K (Class A), 105 K (Class B); accessible parts ≤ 60 K | Rated voltage; 30 min continuous run with load |
| Electrical insulation | Clearance ≥ 3 mm, creepage ≥ 4 mm for basic insulation; dielectric strength 1250 V for basic, 2500 V for reinforced | As per Table of CSA C22.2 No. 1335.1 |
| Resistance to moisture | IPX4 protection against splashing; withstand humidity cycle (93 % RH, 25°C, 48 h) | Hose test after 10 min operation |
Additional Requirements
- Interlock Systems: Food processors must have at least one interlock switch that prevents operation if the lid or bowl is not correctly positioned. The interlock must be positively driven (not rely on spring return alone).
- Locking Mechanism: Blades must stop within 1.5 seconds after opening the lid (tamper-proof design). A brake may be required for high-inertia blades.
- Material Resistance: Food-contact materials must be resistant to staining, corrosion, and thermal degradation. Glass bowls must pass a thermal shock test (90°C to 20°C).
- Overload Protection: Appliances must have thermal cutouts or current limiters to prevent motor burnout under locked-rotor conditions for more than 15 seconds.
- Cord Anchorage: Strain relief must withstand a pull force of 100 N for 1 minute without displacement.
Design Tip: To simplify compliance, manufacturers are encouraged to integrate a mechanical interlock that directly disconnects the motor drive rather than relying solely on electronic sensors. This approach is often simpler to validate and reduces the risk of failure due to sensor drift.
Harmonization: While the standard follows IEC 60335-2-14 closely, Canadian deviations include stricter requirements for cord anchorage and more stringent stability tests (e.g., larger test angle). Always consult the official CSA edition for specific national differences.
Implementation and Testing Considerations
Manufacturers and testing laboratories must follow a structured approach to demonstrate compliance with this standard. The testing sequence typically includes:
- Classification and Marking: Verify that the appliance is clearly marked with rated voltage, power, and model number. Food processors must carry a warning about the risk of blade injury.
- Conditioning: Appliances are operated at 1.1 times rated voltage for 2 hours to stabilize internal temperatures before thermal testing.
- Normal and Abnormal Tests: Including locked-rotor, overvoltage, and component failure simulation.
- Mechanical Tests: Drop test (1 m onto concrete for free-standing units), blade penetration test, and bowl burst pressure test (if applicable).
- Environmental Tests: Humidity, splashing, and storage temperature exposure.
One notable aspect is the requirement for a load simulation during testing. Food processors must be tested with a typical load (e.g., 500 g of ice cubes or 300 g of carrots) to represent worst-case mechanical stress. Tests are conducted in three cycles of 30 seconds each, with 2-minute rest periods between cycles.
Critical Warning: Failure to properly test interlock mechanisms under all lid positions (slightly open, fully open, and with locked bowl) is a common cause of non-compliance. Interlocks must be tested for endurance (5000 cycles) without any loss of function.
Compliance and Certification
In Canada, compliance with CSA C22.2 No. 1335.2.14-93 (2018) is mandatory for food processors under the jurisdiction of provincial electrical safety authorities and is often referenced by the Canadian Electrical Code. Certification is typically obtained through accredited bodies such as CSA Group, Intertek (cETL), or TÜV SÜD Canada.
Certification Process
- Application: Submit technical file including circuit diagrams, bill of materials, and component ratings.
- Testing: Full testing per the standard at an ILAC-accredited laboratory.
- Factory Inspection: Initial inspection of manufacturing facility for quality control and traceability.
- Periodic Audits: Annual follow-up inspections to ensure continued compliance.
It is important to note that the standard was reaffirmed in 2018, meaning the 1993 edition with amendments remains current. Reaffirmation indicates that the technical committee has reviewed the standard and found it still relevant. However, manufacturers should check for any new amendments or interpretations published after 2018.
Compliance Note: If a food processor has been certified to IEC 60335-2-14 by a recognized body, the manufacturer may use a streamlined process for Canadian certification by submitting evidence of the product meeting the stricter Canadian deviations (e.g., cord pull test, stability test). This can reduce duplication of testing by up to 30%.
Frequently Asked Questions
Q: Does CSA C22.2 No. 1335.2.14-93 (2018) apply to commercial food processors used in restaurants?
A: No. The standard is explicitly for household and similar appliances. Commercial food processors are covered by other CSA standards (e.g., CSA SPE-7000 series, or CSA C22.2 No. 1335.2.14 may be applied with additional requirements). It is advisable to consult the certifying body for the appropriate standard scope.

It is advisable to consult the certifying body for the appropriate standard scope.
Q: What are the main differences between the CSA version and IEC 60335-2-14?
A: The CSA version includes additional Canadian national deviations, mainly stricter requirements for cord anchorage (higher pull force), stability tests (steeper incline angle), and more detailed marking requirements (e.g., warnings in both English and French). The CSA edition also adopts the North American voltage ratings (120 V / 240 V) and frequency (60 Hz).

Q: Is the 2018 reaffirmation substantially different from the original 1993 edition?
A: The reaffirmation in 2018 did not introduce new technical requirements. It confirmed that the existing edition (including any amendments up to that date) is still valid. Manufacturers should still refer to the latest consolidated version published by CSA Group, which includes all corrigenda and amendments.

Q: How long does the certification process typically take for a new food processor model?
A: The process takes 8 to 16 weeks on average, depending on the complexity of the design and the laboratory’s schedule. Pre-compliance testing by the manufacturer can reduce time by about 4 weeks. Use of recognized component labels (e.g., UL/CSA for motors and switches) can also accelerate the process.
