Rain testing belongs to the quality-release route

A rain test chamber verifies water ingress risk before the vehicle leaves final assembly. It should not be treated as an isolated booth. The chamber must fit vehicle dimensions, takt requirement, spray zones, water circulation, inspection access, and the acceptance procedure after testing.

Start from Rain Test Booth, then connect it with Final Assembly and Testing Line if the project includes a complete EOL route.

Requirements to define

  • Vehicle envelope, mirror width, roof height, door layout, and underbody exposure
  • Spray zones, nozzle density, pressure or flow requirement, and recipe control
  • Drainage, filtering, water recycling, lighting, and inspection walkway
  • Throughput, test duration, rework loop, and acceptance standard

RFQ checklist

Provide vehicle drawings or dimensions, target throughput, required standard, water supply condition, workshop location, drainage limits, operator access, and whether the chamber should include recipe control or data records.
