IEC 60335-2-24/30 75mm Hemispherical Test Probe

IEC 60335-2-24/30 75mm Hemispherical Test Probe is engineered for safety compliance verification of household electrical appliances, specifically assessing the inaccessibility of internal components such as lamps and heating elements. The probe incorporates a hardened steel hemispherical end for dimensional stability and wear resistance, complemented by a 100mm baffle plate to ensure consistent positioning during testing procedures. Designed to apply negligible force, this instrument validates whether hazardous parts remain inaccessible when protective covers are installed, in strict accordance with IEC 60335-2-24 Clause 21.102 and IEC 60335-2-30 Clause 21.102 requirements for refrigerators, room heaters, and similar domestic appliances.

Technical Specifications

• Probe Diameter: 75 mm ± 0.5 mm (IEC 60335 compliant)
• Probe Length: 50 mm base length (functional length unrestricted for testing applications)
• Hemispherical End Material: Hardened steel (ensuring dimensional accuracy and durability)
• Baffle Plate Diameter: 100 mm
• Baffle Plate Thickness: 10 mm (provides stable probe positioning during compliance verification)
• Applied Force: Negligible force (simulating accidental contact scenarios)
• Primary Function: Verification of internal component inaccessibility with installed protective covers

Standardized Test Procedure

1. Verify proper installation of appliance protective covers (e.g., refrigerator lamp enclosures).
2. Position the test probe with hemispherical end oriented toward the target component.
3. Apply the probe to the appliance surface without exerting appreciable force.
4. Determine whether the hemispherical end contacts the protected component.
5. Document test results as pass/fail based on component accessibility.

Compliance Applications

• Safety testing of internal lamps in refrigerators (IEC 60335-2-24: Clause 21.102 compliance)
• Protection verification for ice maker exposed components (refrigerating appliance category)
• Compliance assessment of room heater internal parts (IEC 60335-2-30: Clause 21.102)
• Quality control validation for ice-cream appliance covered component inaccessibility
