IEC60335‑2‑3 Household Appliance Unintentional Touch Test Tool

This Unintentional Touch Test Tool, also known as the Simulated Hand Test Gauge, is a standardized test probe engineered strictly to IEC 60335‑2‑3 Clause 22.13 and Figure 102. Fabricated from aluminum material, this special test fixture reproduces the geometry of a human hand, designed to identify components beside appliance handles that users may accidentally touch during daily operation.

Many household electrical appliances are fitted with handles for grip and operation. When operators hold or grab these handles, unintended contact with nearby live-risk components creates critical electrical-safety hazards. This simulated hand probe simulates real-world hand-gripping scenarios, locating accessible dangerous zones within 13 mm from the handle bottom. Cooperated with a feeler gauge, it judges whether dangerous parts can be touched unintentionally, helping labs and manufacturers validate product safety against IEC household-appliance safety requirements.

• Applicable Standard: IEC 60335‑2‑3 Clause 22.13, Figure 102
• Construction Material: Aluminum
• Dimension: Overall height 25 mm; key contact points A & B dimension 19 mm; main body length 75 mm; end segment 6 mm; inner step height 6 mm
• Matching accessory: Used together with feeler gauge (per standard Figure 103‑105)
• Test object: Handle‑adjacent zones of household electrical appliances

• Strict IEC‑standard geometry: 1:1 follows Figure 102 dimension requirements, guarantees repeatable, comparable test outcomes for certification.
• Robust aluminum construction: High‑strength aluminium material resists deformation under repeated testing; stable dimension, long service life.
• Real‑simulation hand‑shape structure: Two contact points A and B support dual‑point or single‑point contact test modes, matches the standard test‑operation workflow.
• Easy‑to‑operate: Directly insert into handle openings, cooperate with feeler gauge to finish assessment; no complicated setup required.
• Certification‑ready: Test results are traceable and acceptable for third‑party lab testing and product compliance submission.

This simulated‑hand test fixture is widely adopted in household‑appliance safety inspection, R&D verification, and IEC‑standard product certification.

It is used to detect parts adjacent to appliance handles which could be touched by accident. The probe checks hazardous areas within 13 mm below the handle bottom. Operators insert the simulated‑hand gauge into handle openings, run inspection with a feeler gauge following Figure 104 / Figure 105 procedures. If the handle‑underside profile blocks simultaneous contact of point A and B, perform testing with single‑point contact respectively as required.

This test identifies potential unintended‑touch risks, helps optimize product handle structural design, avoids hidden electric‑shock hazards, and ensures end‑user safety for mass‑produced household appliances.
