IEC 60335 75mm Test Probe with Hemispherical End

IEC 60335 75mm Test Probe with Hemispherical End is built for safety compliance testing of household electrical appliances, focusing on verifying protection for internal components like lamps. It features a hardened steel hemispherical end for durability and a 100mm baffle plate for stable positioning. Designed to apply no appreciable force, it checks if hazardous parts (e.g., exposed lamps) are inaccessible when appliance covers are in place, adhering to IEC 60335-2-24 Clause 21.102 and IEC 60335-2-30 Clause 21.102  for refrigerators, room heaters, and similar devices.

Specifications:
• Probe Diameter: 75 mm ± 0.5 mm (compliant with IEC standards)
• Probe Length: 50 mm (base length; functional length unrestricted for testing)
• Hemispherical End Material: Hardened steel (for wear resistance and consistent shape)
• Baffle Plate Diameter: 100 mm
• Baffle Plate Thickness: 10 mm (aids in stable probe positioning during tests)
• Applied Force: No appreciable force (to simulate real-world accidental contact)
• Core Function: Verifies inaccessibility of internal components (e.g., lamps) with appliance covers installed

Test Procedures:
• Ensure the appliance’s protective covers (e.g., refrigerator lamp cover) are properly installed.
• Hold the test probe, aligning its hemispherical end toward the target component (e.g., internal lamp).
• Apply the probe to the appliance without appreciable force, attempting to touch the target.
• Check if the hemispherical end makes contact with the protected component.
• Record whether the component remains inaccessible (pass/fail).

Applications:
• Safety testing of internal lamps in refrigerators (per IEC 60335-2-24: Clause 21.102).
• Protection verification for ice makers’ exposed components (refrigerating appliance category).
• Compliance checks for room heaters’ internal parts (e.g., heating element lamps, per IEC 60335-2-30).
• Quality control for ice-cream appliances to ensure covered components are inaccessible.
