Test Procedures

1. Prepare the IECEE CEE-7 C21 test device and the 10/16A 250V two-pole fixed socket-outlet specimen, ensuring both components are clean, free from contaminants, damage, or deformation that could compromise test accuracy.
2. Secure the socket-outlet specimen in a stable test fixture according to IECEE CEE-7 C21 standard requirements to prevent movement during testing procedures.
3. Align the test device with the specified position on the socket-outlet specimen as detailed in Fig. 21 of the IECEE CEE-7 standard.
4. Apply the initial specified test force (8±0.5 N) laterally to the socket-outlet specimen through the test device, maintaining the force for the required duration specified in the standard.
