Product Overview
The IEC 60335-1 stability test equipment provides a controlled inclined support surface for electrical appliance stability evaluations associated with IEC 60335-1 Clause 20.1.
During testing, the appliance is positioned on the platform in the applicable use condition and test orientation. The test surface is inclined to the required angle so that the laboratory can evaluate the stability behaviour of the complete appliance under the specified condition.
KINGPO offers three platform configurations with different surface diameters, bearing capacities and angle ranges. Appliance manufacturers, product safety laboratories and third-party testing organizations can therefore select IEC 60335-1 stability test equipment according to the actual appliance footprint, test-condition weight and required inclination range.
Model Selection and Technical Specifications
| Model | Surface Diameter | Angle Range | Bearing Capacity | Inclination Adjustment |
|---|---|---|---|---|
| KP-ST1 | 600 mm | 0–45° | 50 kg | Hand-actuated |
| KP-ST2 | 800 mm | 0–30° | 80 kg | Hand-actuated / motorized |
| KP-ST3 | 1000 mm | 0–30° | 125 kg | Hand-actuated / motorized |
The IEC 60335-1 stability test equipment model should be selected according to appliance dimensions, test-condition weight and the applicable stability test requirement. Laboratories covering several appliance categories should consider the largest intended sample range.
Core Equipment Features
Platform dimensions, load capacity and inclination control are the main configuration factors for IEC 60335-1 stability testing.
01. Three Platform Configurations
The KP-ST series includes 600 mm, 800 mm and 1000 mm platform diameters with corresponding load capacities of 50 kg, 80 kg and 125 kg. This allows IEC 60335-1 stability test equipment to be matched to different appliance sizes and test weights.
02. Adjustable Inclined Test Surface
KP-ST1 provides an adjustable angle range of 0–45°. KP-ST2 and KP-ST3 provide a 0–30° inclination range. The selected configuration should match the applicable IEC 60335 test procedure.
03. Angle Measurement
The system provides an angle measurement accuracy of ±0.5° for checking the inclination of the test surface. The detailed digital inclinometer configuration should be confirmed according to the final equipment configuration.
04. Inclination Adjustment
KP-ST1 uses hand-actuated inclination adjustment. KP-ST2 and KP-ST3 are available with hand-actuated / motorized inclination adjustment configurations according to the selected specification.
IEC 60335-1 Clause 20.1 Stability Test Application
The IEC 60335-1 Clause 20.1 stability test is associated with the evaluation of appliance stability and mechanical hazards. The inclined plane test is used to assess whether an applicable appliance maintains the required stability under the specified test condition.
As an electrical appliance inclined plane tester, the KP-ST series provides the controlled support condition needed for this evaluation. The specimen is positioned according to the applicable use condition and relevant test orientation before the platform inclination is set.
The exact test condition should be determined from the applicable IEC 60335-1 edition and, where relevant, the product-specific IEC 60335 Part 2 standard. Appliance type, movable parts, doors and loading conditions may affect the applicable test procedure.
Inclined Plane Test Principle
Position the Appliance
Place the specimen on the test surface in the condition required by the applicable test procedure.
Adjust the Inclination
Set the platform to the angle required for the applicable stability test.
Check the Test Angle
Use the angle measurement arrangement to check the inclination of the test surface.
Evaluate Stability
Assess the appliance behaviour according to the applicable IEC 60335 requirements.
The IEC 60335-1 stability test equipment provides the adjustable inclined test condition required for the test. Compliance evaluation remains based on the applicable standard and the observed behaviour of the appliance.
For appliances with different operating positions, movable parts, doors or liquid-containing structures, sample preparation and test conditions should be confirmed from the relevant product standard.
Appliance Stability and Safety Evaluation
Electrical appliances intended to stand on a floor, table or other supporting surface may present a safety concern if the complete product can overturn under applicable use conditions.
Stability testing evaluates the appliance as a complete product. Sample footprint, centre of gravity, loading condition and orientation can influence its behaviour on an inclined surface.
Platform Compatibility
IEC 60335-1 stability test equipment should provide sufficient surface area for the specimen and its required test orientation.
Load and Inclination Control
Bearing capacity and the applicable angle range should be reviewed together with sample size and test-condition weight.
Inclined Plane Tester Selection Guide
Appliance Footprint
The 600 mm KP-ST1 platform is intended for smaller appliance samples. Larger footprints may require the 800 mm KP-ST2 or 1000 mm KP-ST3 configuration. Platform size is one of the main factors when selecting IEC 60335-1 stability test equipment.
Sample Weight
KP-ST1 supports loads up to 50 kg, KP-ST2 up to 80 kg and KP-ST3 up to 125 kg. For appliances containing water or other test loads, total test-condition weight should be considered before selecting the electrical appliance inclined plane tester.
Required Inclination Range
KP-ST1 provides a 0–45° inclination range. KP-ST2 and KP-ST3 provide a 0–30° inclination range. The selected IEC 60335-1 stability test equipment should match the applicable IEC 60335 test procedure and relevant product-specific requirements.
Adjustment Method
KP-ST1 uses hand-actuated inclination adjustment. KP-ST2 and KP-ST3 are available with hand-actuated / motorized configurations. Routine testing frequency and sample weight can be considered when selecting the adjustment method.
Typical Test Objects
The IEC 60335-1 stability test equipment is intended for applicable electrical appliances requiring stability testing on a supporting surface.
Application Note:
Sample suitability should be determined according to the appliance type and applicable IEC 60335 Part 2 requirements.
Laboratory and Compliance Applications
Appliance Manufacturer R&D Laboratories
Engineering teams can use IEC 60335-1 stability test equipment during product development to evaluate appliance stability before formal compliance testing and compare different appliance orientations or design configurations.
Product Safety and Compliance Laboratories
The equipment provides a dedicated inclined test surface for IEC 60335-1 Clause 20.1 stability test projects. Different platform sizes help laboratories match the electrical appliance inclined plane tester to their normal sample range.
Third-Party Testing Organizations
Independent laboratories may test appliances with different dimensions and weights. The 600 mm, 800 mm and 1000 mm platform configurations support a wider range of sample requirements.
IEC 60335 Laboratory Equipment Projects
The IEC 60335-1 stability test equipment can be configured as part of an electrical appliance safety testing laboratory according to the standards and appliance categories covered by the laboratory.
Practical Procurement Value
For appliance stability testing, a larger platform is not automatically the most suitable configuration.
The IEC 60335-1 stability test equipment should match the actual appliance footprint and test-condition weight while providing the required inclination range. An oversized platform may occupy unnecessary laboratory space, while an undersized platform can restrict specimen positioning or sample compatibility.
The three KP-ST configurations allow laboratories to select IEC 60335-1 stability test equipment according to actual appliance dimensions, bearing requirements and IEC 60335-1 Clause 20.1 stability test applications rather than relying on one fixed platform specification.
Compliance & Regulatory Assurance
- The IEC 60335-1 stability test equipment is designed for stability evaluations associated with IEC 60335-1 Clause 20.1, providing an adjustable inclined support surface for applicable household and similar electrical appliances.
- Test conditions should be determined according to the applicable IEC 60335-1 edition and relevant product-specific IEC 60335 Part 2 requirements. Appliance type, loading condition, movable parts and test orientation should be confirmed before formal compliance testing.
