NF C 61-314 Figure 10 Gauge for Checking Non-Accessibility of Live Parts Through Shutters SC-TT03
Product No: SC-TT03 (1 N thrust test probe)
Standard requirement: NF C 61-314 (February 2008) Prises de courant pour usages domestiques et analogues – Systèmes 6 A / 250 V et 16 A / 250 V. Figure 10 is the gauge (calibre) for checking the non-accessibility of live parts through the shutters of socket-outlets.
Application
The Figure 10 gauge verifies that the shutters of a socket-outlet prevent access to live parts. The gauge is placed over the shutter with its face in full contact with the socket-outlet face, and the rigid steel wire is pushed along its axis with a thrust of 1 N. The wire shall not touch the live parts or make electrical contact through the shutters. A flexible test lead is fitted so that any contact with live parts is indicated by an electrical circuit.
Construction
- Stainless steel gauge body, Ø50 mm outside diameter with Ø30 mm guide opening, body length 60 mm minimum
- Rigid steel probe wire Ø1 mm (+0.015/0) × 80 ± 0.5 mm, tip rounded R0.05 mm
- Internal calibration spring: with a thrust of 1 N applied on the wire, surface A–A′ is brought practically to the same level as surface B–B′
- Flexible test lead for electrical indication of contact
