VDE0620-2-1:2021 Figure Bild16d 2.5A Temperature Rise Plug Gauge

GNGPL-6217BILDD 2P AC2.5A standard test plug is precisely manufactured according to Figure 16d of DIN VDE 0620-2-1:2021, a dedicated gauge for temperature rise test of German low-current plugs and sockets specified in Clause 19. With standardized outline, precise pin dimensions and designated materials, it simulates actual mating state of 2.5A low-power plugs to accurately test temperature rise of internal socket contacts. For appliances with auxiliary power supply, it can be used with 1.5 mm² single-core wires for loaded temperature rise test on the premise that auxiliary circuit is separable and causes no temperature measurement interference. It is widely applied in laboratory calibration, small home appliance connector type test and thermal resistance verification.

Specifications:
• Standard: DIN VDE 0620-2-1:2021, Figure 16d, 2P, Rated AC 2.5A
• Housing Material: PC Polycarbonate
• Pin Contact: Brass CuZn39, comply with DIN EN 12164 & DIN EN 12167, nickel-plated per DIN EN ISO 4042
• Contact Bridge: Copper, cross-section 2.5 mm²
• Key Dimensions:
– Pin diameter: Φ4±0.06 mm, positioning cylinder Φ3.8±0.1 mm
– Pin length: exposed length 19±0.5 mm, positioning section 10±0.5 mm, step height 4±0.2 mm
– Cover overall height: 25±0.5 mm
– Pin center distance: 19±0.2 mm on end face plane, 17.2±0.2 mm at pin end
– End face total length 35.3±0.2 mm, arc R=5±0.5 mm, 45° inclined surface with length 26.1±0.2 mm, end face height 13.7±0.2 mm
• Matching Cable: 2 pieces of 1.5 mm² single-core wire, each 1 m long

Test Procedures:
• Pre-inspection: Verify outline, pin size and nickel plating conform to drawings, confirm good conduction of contact bridge.
• Standard Temperature Rise Test: Fully insert the plug into tested socket, apply rated 2.5A load current according to Clause 19, arrange temperature measuring equipment to collect real-time thermal data.
• Test for auxiliary-function products
– Connect two 1 m long 1.5 mm² single-core wires for auxiliary power supply;
– This plug is only allowed for test when auxiliary circuit can be separated independently and brings no disturbance to temperature measurement;
– Test with this plug is forbidden if auxiliary circuit cannot be detached.
• Result Judgment: Maintain power until temperature stabilizes, record peak temperature rise and judge qualification against standard limits.

Applications:
• Third-party Labs: VDE/TÜV/CQC type certification temperature test for German low-current sockets;
• Small Home Appliance Industry: Factory thermal sampling inspection for desk lamps, chargers and 2.5A EU sockets;
• Connector Manufacturers: R&D verification for heat-resistant structure of low-voltage connectors and terminals;
• Metrology Institutions: Calibration and traceability calibration for temperature rise testing instruments;
• Import & Export Inspection: Customs spot check and quality screening for exported low-power plugs and sockets.
