Test Procedures:
• Prepare the testing device and the 10/16A 250V two-pole fixed socket-outlet to be tested, ensuring both are clean, free from debris, damage, or deformation that may affect test accuracy.
• Secure the socket-outlet in a stable fixture according to IECEE CEE-7 C21 standard requirements to prevent movement during the test.
• Align the testing device with the specified position of the socket-outlet as indicated in Fig. 21 of the standard.
• Apply the first specified test force (8±0.5 N) laterally to the socket-outlet through the device, maintaining the force for the required duration.
• Observe and record the socket-outlet’s deformation, structural integrity, and any signs of failure during and after the force application.
• Repeat steps 3-5 with the second specified test force (15±0.5 N) to further evaluate the socket-outlet’s resistance to lateral strain.
• Compare the test results with the requirements of IECEE CEE-7 C21 standard to determine if the socket-outlet meets the resistance to lateral strain criteria.
• After the test, remove the device gently and store it in a dry, dust-free environment to preserve its precision and service life.
