Rotating Barrel Drop Test Machine

Rotating Barrel Drop Test Machine is engineered for compliance with IEC 60068-2-31 Annex A (superseding IEC 60068-2-32) and IEC 60884-1 Clause 24.3 standards, which specify mechanical strength test requirements for electrical accessories. This equipment evaluates the drop resistance of electrical accessories through standardized testing protocols.

Standards Compliance: IEC 60068-2-31 / GB/T 2423.7 “Basic environmental testing procedures Part 2: Tests – Test method: Free fall” Annex A; IEC 60884-1 / GB/T 2099.1 “Plugs and socket-outlets for household and similar purposes – Part 1: General requirements” Clause 24.3.

Test Objectives:

• Assessment of outer shell durability
• Evaluation of internal structure drop resistance under heavy impact conditions
• Verification of adaptability to repeated free fall events

Testing Methodology: The Rotating Barrel Drop Test Machine simulates free fall conditions encountered during normal user operation. The test procedure involves:

• Manual insertion of the equipment under test (EUT) into the rotating barrel
• Secure closure of the transparent cover and protective safety devices
• Motor-driven clockwise rotation of the barrel against time
• Completion of one rotation cycle, resulting in two drop events

Operational Parameters:

• Drop frequency controlled by motor operation (5 rpm standard)
• Configurable drop heights: 500mm or 1000mm
• Barrel geometry ensures randomized EUT orientation during falls, preventing abnormal friction and collision patterns
