Description
This CEI 23-50 C5 Standardization Sheet (formerly CEI UNEL 09319-64 2A and 2B) Calibration Gauges for S30, S31, and S32 Plug Pin Spacing Inspection comprises a specialized set of dimensional verification tools engineered to inspect the pin spacing of S30, S31, and S32 plugs. The system strictly complies with the CEI 23-50 standard (formerly CEI UNEL 09319-64 2A and 2B), serving as an essential quality control instrument for plugs utilized in household and similar applications. Accurate verification of pin spacing is critical for ensuring reliable compatibility with corresponding sockets, maintaining stable electrical contact, and preventing connection failures or potential safety hazards.
Specifications
- Compliance: Conforms to CEI 23-50 “Spine e prese per usi domestici e similari – Parte 1: Prescrizioni generali” C5 (formerly CEI UNEL 09319-64 2A and 2B)
- Application Scope: Dedicated to dimensional inspection of pin spacing for S30, S31, and S32 plugs
- Gauge Types: Fork gauge (Calibro a forchetta, Type A) and flat gauge (Calibro platto, Type B)
- Fork Gauge (Type A) Dimensions (mm):
- Curved prongs (Spigli arcantati): 24.08-0.02
- Rounded prongs (Spigli arrotondati): 13.92+0.02
- Additional dimension: 5±0
- Core Function: Fork gauge verifies external pin spacing; flat gauge verifies internal pin spacing
- Key Requirement: Neither gauge shall require force during the inspection process
- Unspecified Dimensions: Not constrained by the standard’s unified requirements
Test Procedures
- Prepare the S30, S31, or S32 plug under test, ensuring its pins are clean, intact, and free from deformation or misalignment.
- Inspect both the fork gauge (Type A) and flat gauge (Type B) to confirm they meet the specified dimensional requirements and have no wear or damage.
- Use the fork gauge (Type A) to check the external spacing of the plug’s pins: Align the gauge’s prongs with the outer edges of the pins and position it without applying force.
- Verify that the fork gauge fits smoothly… (truncated)
