IEC 61386-21 Figure 102 Gauge For Checking The Minimum Inside Diameter Of The Conduit System
 
 
Product information:
 
This gauge is the minimum inner diameter gauge for metal conduits and other materials after bending tests. When the sample is tested in IEC61386-21, clause 10.4.101 (one end of the sample is vertical and the other end is at a 45° angle to the vertical line), this gauge should pass through the sample with no initial velocity. Comply with the requirements of Clause 6.7.2 and Figure 12 of JG3050-1998 "Insulated Electrical Bushings and Accessories for Buildings", "GB 20041.21-2008 Conduit Systems for Cable Management - Special Requirements for Rigid Conduit Systems", GB/T14823.2 "Conduits for Electrical Installation" Special requirements - Rigid insulating material flat conduit", ZBG33008 "Polyvinyl chloride plastic corrugated wire conduit" and IEC61386-21 Section 10.4.101 and Figure 102 and IEC61386-22 Section 10.4.102 and Figure 102 and other requirements.
