IEC 60335‑2‑11 75mm Hemispherical End Test Rod for Heater Safety Test

This 75 mm Hemispherical‑End Test Rod is a standard test probe built strictly to IEC 60335‑2‑11 Clause 11 Table 101. Its main probe body is constructed from stainless steel, paired with an insulated nylon handle. This special‑purpose test tool is developed for safety assessment of household heating appliances.

Household heaters may generate high‑temperature surfaces during operation. Under real‑world usage conditions, users could accidentally touch hot zones. This hemispherical‑tip test rod simulates physical contact scenarios, helping laboratories and manufacturers verify whether accessible surfaces of heating devices satisfy international safety‑related temperature‑limit requirements. It delivers repeatable test data for product R&D adjustment, internal quality inspection and third‑party IEC certification applications.

• Applicable Standard: IEC 60335‑2‑11 Clause 11, Table 101
• Probe Diameter: Φ75 mm
• Probe Structure: Rod with hemispherical end, unlimited effective length
• Probe Material: Stainless steel
• Handle Material: Nylon
• Test Object: Household heaters

• Strictly standard‑compliant geometry: 75 mm diameter with hemispherical end fully matches IEC 60335‑2‑11 Table 101 specification, ensuring consistent and reproducible test outcomes for certification reports.
• Durable stainless‑steel probe body: Resists deformation, maintains precise dimension under frequent continuous lab testing.
• Insulated nylon handle: Provides safe manual operation for operators during high‑temperature sample assessment.
• Simple‑to‑use structure: No complex assembly required. Directly apply the test rod against heater surfaces to complete surface‑contact evaluation.
• Certification‑acceptable performance: Test results generated by this fixture are traceable and valid for IEC compliance submissions for household heating appliances.

This hemispherical‑end test rod is widely used for R&D verification, factory QC and third‑party lab certification of household heaters.

Following IEC 60335‑2‑11 test workflow, operators use this Φ75 mm hemispherical‑tip rod to assess accessible areas of heater units. The test simulates real‑life contact conditions, evaluating whether the heater's surface meets standard temperature‑threshold requirements.

By performing this assessment, engineers can identify over‑temperature risks, optimize heater structural layout and surface‑protection design, and prevent potential burn hazards for end‑users. This test fixture is an essential piece of hardware for heating‑appliance manufacturers to achieve international market access.
