The compressive strength performance of rural lighting Ready Board Box in Africa must prioritize compliance with the IEC 61439-3 standard to suit rural African usage scenarios.

Core Pressure Resistance Standard

1. Top static load (most critical):

1. Standard value: 8500N (approximately 867 kg) uniformly distributed load, sustained for 1 minute.

2. Judgment: No permanent deformation, door/lock hinge opens and closes normally, electrical clearance meets standards.

3. Rural Simplification: Minimum 2,500 N (approximately 255 kg), Recommended 5,000 N (approximately 510 kg) for a balance between cost and safety.

2. Ready board side / Door body:

1. Ready board body: 1200N (approximately 122 kg) vertical force, no deformation or loosening.

2. Ready board side: 1000N/m² uniformly distributed load, no dents or cracks.

3. Impact resistance: IK08 (10J), resistant to stone and tool impacts.

Material and Structural Requirements

Steel plate: ≥1.5mm cold-rolled / stainless steel, with stiffener spacing ≤400mm.

Plastic housing: PC/ABS flame-retardant modified, with a bending strength ≥50MPa and no brittleness.

Protection rating: IP54/IP65, dustproof and waterproof, suitable for high-temperature and high-humidity environments in Africa.

Test points

Static Load: Apply pressure with a fully laid steel plate at the top, then unload after 1 minute, measuring a deformation of ≤1%.

Door body: Apply force at the center of the door, maintain 1200N for 30 seconds, no plastic deformation.

Impact: IK08 hammer strike at 6 points, no cracking, no detachment, protection rating remains unchanged.

4. Rural Scene Adaptation

Minimum Qualification: 255 kg (2500N) top load, meets basic load-bearing requirements.

Recommended standard: 510 kg (5000N) top load, resistant to accidental stepping or falling objects.

High-quality configuration: 867 kg (8500N) top load, suitable for extreme environments and extended lifespan.
