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.
Technical parameters:
1. Material: steel, surface hard chromium plated
