Test Probe 41 of IEC 61032 – Test Cone for Access Probes to Hazardous Hot or Glowing Parts

IThis IEC 61032 Test Probe 41 is a specialized test cone built specifically to check if hazardous hot or glowing parts in electrical appliances are out of users’ reach. It has a tapered cone shape with precise dimensions—key for mimicking accidental human contact with hot components. Made from heat-resistant stainless steel, it won’t warp or damage even when used near high-temperature parts. Lightweight but rigid, it’s easy to handle during tests, making it reliable for safety compliance checks on heaters, toasters, and ovens, while fully meeting global safety standards.

Standards:

Specifications:
Probe Type: IEC 61032 Test Probe 41 (test cone for hot/glowing parts)
Cone Taper: 1:5 (standardized to simulate accidental human contact)
Total Length: 100 mm ± 0.2 mm
Effective Working Length: 80 mm
Base Diameter: 10 mm ± 0.1 mm
Material: Heat-resistant stainless steel (resists deformation near high temperatures)
Applied Force: No appreciable force (mimics light, accidental contact)
Core Function: Verifies inaccessibility of hazardous hot or glowing components in appliances

Test Procedures:
1. Check the test cone for damage (like dents or rust) that could affect results.
2. Turn on the appliance and let it reach operating temperature (until hot/glowing parts activate).
3. Gently guide the test cone’s tip toward access points near hot/glowing parts.
4. See if the cone touches any hazardous hot or glowing components.
5. Record if the parts stay inaccessible (pass/fail).

Applications:
1. Safety testing of hot parts in fixed room heaters (per IEC 61032:2021 Figure 15).
2. Compliance checks for glowing elements in portable electric space heaters (UL 1278:2023 Clause 15.4).
3. Verifying hot component access in household toasters (IEC 60335-1:2023 Clause 22.11).
4. Safety checks for internal hot parts in electric ovens (aligning with IEC 60335-2-30:2023).
5. Quality control for small heating appliances (e.g., electric grills) to prevent burn risks.
