CEI 23-50 C7 Standardization Sheet Gauge for S30/S31/S32 Plug to P30 Socket Interchangeability Verification

This professional testing gauge is engineered in strict compliance with CEI 23-50 Normalization Sheet C7 standard requirements, specifically designed to verify interchangeability between S30, S31, and S32 plugs and P30 sockets. Featuring a stably assembled integrated structure, the gauge ensures tested plugs can fully insert into the matching gauge (simulating P30 sockets) without excessive force, which is critical for guaranteeing compatibility and reliable electrical connections in plug and socket products, while eliminating potential safety risks associated with poor interchangeability. This device is essential for enterprises and institutions engaged in production, quality control, and compliance certification of household and similar electrical plug and socket components.

Specifications
• Complies with CEI 23-50 Normalization Sheet C7 standard requirements
• Features key dimensional parameters including 3.26±0.08 mm, 4.60/3.26 mm, 32.6±0.08 mm, 37.1±0.08 mm, 5.1±0.01 mm and 15.4 mm
• Utilizes a firmly fixed integrated structure with all components stably assembled to prevent loosening during testing operations
• Specifically designed for verifying interchangeability of S30, S31, and S32 plugs with P30 sockets
• Requires that tested plugs fully penetrate the gauge without forced operation to meet interchangeability criteria
• Maintains high dimensional accuracy and structural stability to ensure consistent test results through repeated applications

Test Procedures
• Prepare the gauge and the S30, S31, and S32 plugs to be tested, ensuring both gauge and plug surfaces are clean, free of burrs, deformation, or rust that could compromise test accuracy.
• Verify that all gauge components are stably fixed with no structural looseness that might affect test integrity.
