109 Retention of Blades Test
109.1 A flush or self-contained receptacle having a 5-15R, 5-20R, 6-15R, or 6-20R configuration shall be
subjected to the retention of blades test described in this Section.
Exception: A receptacle having a 1-15R, 5-15R, 5-20R, 6-15R, or 6-20R configuration and not of the
flush or self-contained type may instead be subjected to the Retention of Plugs Test, Section 114.
109.1 revised November 16, 2012
109.2 Receptacles having the break-off tab, when provided, removed from one nonidentified terminal are
to be subjected to ten conditioning cycles of manual insertion and withdrawal of a standard gauge, see
Figure 109.1. Each of six devices is to be tested. The gauge is to be configured as outlined in Table 109.1.
The force applied to insert the gauge for any of the conditioning cycles is not to exceed 40 lbf (178 N).
The gauge is to have the dimensions indicated in Figure 109.1 but is not to have holes in the outer ends
of the blades.
Figure 109.1 Test gauge
NOTES
1) Blades shall be made of tool steel, Rockwell Hardness C58 to C60.
2) All sharp edges shall be removed to a radius of 0.016 to 0.020 inch. Ends of all flat blades bevelled as shown in the end of
blade detail.
3) Blade surfaces shall not exceed a 32 microinch finish grind in a direction perpendicular to the major axis. Finish is to be
determined visually using a comparative method and 10 X optical magnification.
4) All blade hole positions are located on the centerline of the blades.
5) R designates radius. All dimensions are in inches.
6) Flat blade positions shall be modified to suit configurations 5-20 and 6-20.

109.3 The standard gauge is to be configured as shown in Table 109.2 using the line blades without
holes and with the grounding blade removed. The gauge is then to be inserted in the receptacle and a
static 3 lbf (13.3 N) (including the weight of the gauge), which tends to remove the gauge from the
receptacle, is to be applied for a period of 1 minute in a direction normal to the plane of the face of the
receptacle. There shall not be more than 0.079 inch (2 mm) displacement of the gauge.

a Test gauge having grounding blade removed.
109.4 The standard gauge is to be configured as shown in Table 109.3 using the line blades with holes
in the end and with the grounding blade in place. The gauge is then to be inserted in the receptacle and
a force applied in a direction normal to the plane of the face of the receptacle that tends to remove the
gauge. The static force required to withdraw the gauge shall not exceed 15 lbf (67 N) (including the weight
of the gauge).
109.2. Each line contact shall be capable of withstanding for 1 minute a static 0.5 lbf (2.2 N) applied to
the test blade in a direction normal to the plane of the face of the specimen and in a direction that tends
to remove the test blade, when the test blade is fully inserted in the contact opening. There shall not be
more than 0.079 inch (2 mm) displacement of the test blade.

2 oz (57 g) ground pin
Material: Pin-Steel, Rockwell Hardness C58 to C60.
Handle – cold rolled steel
NOTES
1) The ground pin is to be fastened to handle in rigid manner.
2) Length not specified. Total tool weight 2 oz (57 g).
3) Axis of blade and axis of handle, must have combined concentricity and axial alignment of 0.006 maximum at tip of pin.
4) The blade surfaces shall not exceed a 32 microinch finish grind in a direction perpendicular to the major axis.
Finish is to be determined visually using a comparative method and 10 X optical magnification.

Application:
Shice equipment offers a wide range of gauge to meet the most common standards including those from IEC, EN, UL, DIN, VDE and others. Such standards require the checking of size & definition etc. these gauges are constructed from senior stainless steel and appropriate steel with a hardness of at least 52-58 HRC and a roughness according to standard require. Each gauge is supplied with a certificate of calibration.
