2. Reference Standards
This inspection is conducted in accordance with the following standards and requirements, applicable to FIR sauna rooms exported to Canada:
- Canadian Electrical Safety Standard: CSA C22.2 No. 68-14 (Electric Heating Equipment for Residential and Commercial Use)
- Canadian Building Materials Safety Standard: CAN/CSA-Z240.4.1-16 (Wood Products for Indoor Use)
- Far-Infrared Radiation Safety Standard: IEC 62233 (Safety Requirements for Electrically Heated FIR Devices)
- Supplier’s Product Specifications and Canadian Customer’s Quality Requirements
3. Inspection Scope & Methodology
3.1 Inspection Scope
A total of 50 units of FIR sauna rooms (batch No.: FIR20260105) were inspected, covering the following key items:
- Electrical System (power supply, wiring, grounding, insulation, control panel)
- FIR Heating Components (heating panels, radiation intensity, temperature uniformity)
- Structural Safety (wooden frame, door lock, ventilation system, load-bearing capacity)
- Appearance & Workmanship (surface finish, splicing, coating, color consistency)
- Accessories (seats, foot mats, remote control, user manual)
- Labeling & Certification (compliance labels, warning signs, CSA certification marks)
- Packaging (moisture-proof, shock-proof, export marking compliance)
3.2 Inspection Methodology
- Visual Inspection: Check appearance, labeling, splicing, and surface defects.
- Instrument Testing: Use multimeters, insulation testers, FIR radiation detectors, and temperature sensors to verify electrical performance and FIR function.
- Functional Testing: Test heating speed, temperature control accuracy, door lock operation, and ventilation efficiency.
- Sampling Inspection: Randomly select 10 units for detailed performance testing; full inspection for critical safety items (electrical insulation, grounding).
- Defect Verification: Mark and record defects, classify them by severity, and verify after handling.
4. Inspection Results
4.1 Qualified Items
After inspection, the following items of the tested products meet the Canadian export standards and customer requirements:
- FIR radiation intensity (range: 5.0-7.5 μm, meeting IEC 62233 requirements).
- Load-bearing capacity of wooden frame and seats (able to bear 150kg without deformation).
- Ventilation system efficiency (air exchange rate ≥ 0.5 times/hour).
- User manual content (complete English instructions, compliant with Canadian safety warning requirements).
- Export packaging marking (correct destination, batch number, and moisture-proof labels).
4.2 Defects & Imperfections
During the inspection, various defects were identified and classified into critical defects (affecting safety and usability) and minor imperfections (cosmetic or non-critical functional issues). Details are as follows:
4.2.1 Critical Manufacturing Defects (Total 8 Units)
| Defect Description | Quantity (Units) | Impact |
|---|---|---|
| Electrical insulation failure: Insulation resistance < 1MΩ (required ≥ 2MΩ), risk of electric shock. | 3 | Violates CSA C22.2 No. 68-14, poses safety hazards for end users. |
| FIR heating panels not working: No heat output or radiation detected, complete functional failure. | 2 | Product unable to perform core function, unfit for use. |
| Loose wooden frame splicing: Gaps > 5mm between panels, risk of structural collapse during use. | 2 | Violates CAN/CSA-Z240.4.1-16, fails structural safety requirements. |
| Missing grounding wire: No effective grounding connection, increased electric shock risk. | 1 | Non-compliant with Canadian electrical safety standards, critical safety defect. |
4.2.2 Minor Imperfections (Total 12 Units)
| Imperfection Description | Quantity (Units) | Impact |
|---|---|---|
| Surface scratches: Wooden panels have minor scratches (length 2-5cm, depth < 0.5mm). | 5 | Cosmetic defect, no impact on functionality or safety. |
| Color inconsistency: Slight color difference between door panel and side panels (ΔE < 2). | 3 | Aesthetic issue, meets basic quality requirements but not optimal. |
| Remote control response delay: 1-2 second delay when adjusting temperature. | 2 | Minor functional inconvenience, does not affect overall usability. |
| Coating bubbles: Small bubbles (diameter < 3mm) on metal control panel surface. | 2 | Cosmetic defect, no impact on electrical performance. |
5. Defect Handling Measures
Our QC team conducted a comprehensive inspection, marked all defective products, and implemented the following handling measures:
- Critical Defect Handling: The 8 units with critical manufacturing defects wereremoved and segregated from the delivery batch to prevent substandard products from being shipped. These units will be returned to the production line for rework or scrapped based on defect severity.
- Minor Imperfection Handling: The 12 units with minor imperfections were marked and recorded. A detailed correction plan was formulated, including polishing scratches, adjusting color consistency, and calibrating remote controls. These units will be re-inspected after correction to ensure compliance before delivery.
- Report Submission: This QC Report was promptly sent to the Canadian customer to support delivery evaluation, defect correction confirmation, and replenishment arrangement for the 8 removed units.
6. Conclusion
Of the 50 FIR sauna rooms inspected, 30 units are fully compliant with Canadian export standards and customer quality requirements, 12 units have minor imperfections (correctable via rework), and 8 units have critical manufacturing defects (removed from delivery). The overall quality of the batch meets basic export requirements after handling critical defects.
It is recommended that the supplier implement the correction measures for minor imperfections as soon as possible, complete re-inspection, and arrange replenishment of the 8 defective units to ensure on-time delivery to the Canadian customer. Follow-up inspections should focus on electrical system and structural safety to avoid recurrence of critical defects.
