IEC 60884-1 Clause 14.2 Figure 17 Non-Solid Pin Hardness Testing Device

The LS-B04 IEC 60884-1 Clause 14.2 Figure 17 Non-Solid Pin Hardness Testing Device is a precision instrument engineered to evaluate the mechanical strength and structural integrity of non-solid pins in accordance with international electrical safety standards. This device employs a calibrated steel rod to apply a perpendicular force of precisely 100N to the pin surface. Following a standardized dwell time of one minute, the resultant deformation is measured to verify compliance with specified tolerance limits.

This testing methodology ensures that non-solid pins possess adequate hardness and dimensional stability to withstand operational mechanical stresses, thereby validating structural reliability in practical applications. The device’s manual rotary handwheel provides controlled force application, while the Φ4.8mm steel rod maintains consistent contact geometry throughout the testing procedure.

Compliance Standards:
• IEC 60884-1:2022 – Plugs and socket-outlets for household and similar purposes – Part 1: General requirements
• VDE 0620-2-1:2021 – Connectors for household and similar purposes – Part 2-1: Particular requirements for plugs
• GB/T 2099.1-2021 – 家用和类似用途插头插座 第1部分：通用要求 (Plugs and socket-outlets for household and similar purposes – Part 1: General requirements)

Technical Specifications:
• Steel rod diameter: Φ4.8mm ±0.05mm
• Applied force: 100N ±2%
• Force application: Manual rotary handwheel with calibrated mechanism
• Test duration: 60 seconds ±1 second

Test Methodology:
A Φ4.8mm steel rod applies 100N perpendicular to the non-solid pin axis for 60 seconds. Post-test measurements must confirm:
1. Deformation at pressure point: ≤0.15mm
2. Overall dimensional change: ≤0.6mm
These parameters determine whether the non-solid pin meets the hardness requirements specified in IEC 60884-1 Clause 14.2 Figure 17.
