African rural lighting Ready Board Box impact resistance test impact angle and impact frequency

African rural lighting ready boards comply with the IEC 62262 international mechanical impact standard, and South Africa's SANS 10198 synchronously adopts this specification. African rural lighting ready boards uniformly use pendulum type impact devices to complete IK impact resistance tests, with clear mandatory requirements for impact angle and frequency.

Impact angle standard: The axis of the pendulum impact hammer head is perpendicular to the surface of the tested box, and the impact incidence angle is strictly controlled at 90 °. Tilt impact is prohibited; For weak positions such as corners, door frames, and observation windows of the box body, the axis of the pendulum should be perpendicular to the tangent line of the contact surface to ensure that the impact energy is completely perpendicular to the shell, eliminate the interference of oblique force, and simulate the vertical impact conditions of stones, agricultural tools, and handling collisions. The small energy test of the spring impact hammer also maintains the hammer head perpendicular to the panel, without any deviation angle test.

Impact frequency specification: After the complete installation of the African rural lighting ready board on the rigid bracket, all exposed test surfaces should be divided first, and at least 5 weak impact points (panel center, corners, hinges, lock holes, transparent windows) should be uniformly selected on each surface. The distance between adjacent impact points should not be less than 50mm, and each point should be impacted once; For vulnerable and critical parts such as plastic boxes, thin-walled door covers, and transparent windows, conduct 3 repeated impact tests at the same point to verify their ability to withstand repeated impacts. In rural Africa, there are many scenarios where sand and gravel collide with agricultural tools. Export products generally use IK08 (5J) grade, with a cumulative impact of no less than 20 times on all exposed surfaces of the machine, and an additional 3-5 rechecks for fragile areas at the corners.

Experimental judgment: After all impacts are completed, the box must have no through cracks, no exposed live parts, no sealing failure, and the IP protection level must remain unchanged to meet the long-term mechanical strength requirements for rural households in Africa.
