IEC 60335 75mm Test Probe with Hemispherical End

IEC 60335 75mm Test Probe with Hemispherical End is engineered for safety compliance testing of household electrical appliances, concentrating on verifying protection for internal components such as lamps. It incorporates a hardened steel hemispherical end for enhanced durability and a 100mm baffle plate for stable positioning. Designed to exert no appreciable force, it evaluates if hazardous parts (e.g., exposed lamps) remain inaccessible when appliance covers are secured, conforming to IEC 60335-2-24 Clause 21.102 and IEC 60335-2-30 Clause 21.102 for refrigerators, room heaters, and analogous devices.

Specifications:

• Probe Diameter: 75 mm ± 0.5 mm (in compliance 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 (facilitates 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.
