Receptacle Test Fixture of UL 498 Figure 118.1

Assembly Security Test

A flush receptacle having a 5-15R,5-20R,6-15R,or 6-20R configuration is to be mounted in the fixture described in Figure 118.1, and 50 lbf (220 N) is to be applied, as shown in Figure 118.2, for a period of 10 s by means of a push-out tool inserted into the slots of the receptacle.

The push-out tool required for configuration 5-15R is to be as shown in Figure 118.3. The tool used for configurations 5-20R, 6-15R,and 6-20R is to have the same design but is to be modified to fit the slots. For a single receptacle, the push-out tool (see Figure 118.3) is to be modified to have a single set of blades.

Exception: A self-contained receptacle having a 5-15R,5-20R,6-15R, or 6-20R configuration shall
instead be subjected to the Assembly Security Test, Section 144.

There shall not be any mechanical breakage of the receptacle that exposes live parts or separation of the face and body by more than 1/16 inch (1.6 mm), measured after removal of the applied force. There shall not be any permanent deformation of the yoke that would render the receptacle incapable of functioning as intended.

The receptacle is then to be placed in an inverted position in the test fixture and the 50 lbf (220 N) applied, as shown in Figure 118.4, for a period of 10 s by means of a bridge as shown in Figure 118.5. The criteria of 118.2 shall apply.

The receptacle shall maintain grounding continuity between the grounding terminal and ground pin. An indicating device such as an ohmmeter, a battery-and-buzzer combination, or similar device is to be used to determine compliance. Additionally it shall be capable of retaining without displacement in excess of 0.079 inch (2 mm) for 1 minute after insertion, the fully inserted test pin illustrated in Figure 119.3.

For this test, each receptacle is to be placed with its face horizontal so that the downward force exerted by the pin is perpendicular to the plane of the receptacle face and tends to withdraw the pin.
