QJSCY-1215 Stainless Steel Enclosed Rain Test Chamber

Overview

The QJSCY-1215 Stainless Steel Enclosed Rain Test Chamber is an engineered environmental simulation system designed to evaluate the ingress protection (IP) performance of enclosures—particularly against vertically falling, oscillating, or directed water spray—as defined in IEC 60529, GB/T 4208–2017 (equivalent to EN 60529), and ISO 20653 for road vehicles. Unlike open-loop drip or static spray setups, this chamber employs a precisely calibrated oscillating pipe system with 25 uniformly spaced nozzles (φ0.1–0.4 mm orifice diameter), delivering repeatable raindrop size distribution and impact kinetics consistent with real-world exposure conditions. Its fully enclosed stainless steel construction ensures long-term corrosion resistance, thermal stability during extended tests, and compliance with laboratory safety and containment requirements for wet testing environments.

Key Features

• Robust enclosure: Inner chamber fabricated from SUS304 2B brushed stainless steel; outer shell constructed from cold-rolled steel with anti-rust pretreatment and electrostatic powder coating
• Oscillating spray arm: Dual-axis swing mechanism (±60° total range, 120° sweep) with programmable dwell time and angular velocity (full cycle: ~12 seconds)
• High-fidelity nozzle array: 25 precision-drilled nozzles (φ16 mm pipe diameter), spaced at 50 mm intervals, generating uniform droplet distribution across a 400 mm radius spray field
• Flow-controlled delivery: Integrated digital flowmeter and pressure-regulated water supply ensure stable volumetric flow rate (1.8 L/min total, ±2% repeatability per ISO 5167)
• Extended timing resolution: Microprocessor-based controller supports test duration programming from 1 second to 99 hours, 99 minutes, 99 seconds—with power-loss recovery and event logging
• Drainage-optimized sample platform: Custom stainless steel turntable with laser-drilled drainage holes (pitch: 8 mm) to prevent pooling and enable dynamic orientation testing
• Modular integration capability: Optional wind speed module (0–12 m/s, turbulence <15%) compliant with IPX5/IPX6 wind-assisted test protocols

Sample Compatibility & Compliance

The QJSCY-1215 accommodates samples up to 800 mm × 800 mm × 800 mm (W×D×H), making it suitable for automotive headlamps, outdoor LED signage, industrial control cabinets, railway signaling housings, and marine electronics enclosures. It meets mandatory test conditions for IPX1 through IPX6 classifications under IEC 60529, as well as GB/T 4208–2017 Annex B (rain test methods), GB/T 4942.2–1993 (rotating electrical machines), and ISO 20653:2013 (road vehicles – degrees of protection against ingress of water). All operational parameters—including flow rate, oscillation angle, and dwell time—are traceable to NIST-traceable calibration standards. The system supports GLP-compliant test record generation when paired with optional audit-trail software.

Software & Data Management

While the base unit features a standalone 7-inch TFT touchscreen HMI with real-time parameter display and manual override, optional PC-based software (RainTest Pro v3.2) enables full test sequence automation, data export (CSV/Excel), digital signature authentication, and 21 CFR Part 11–compliant electronic records—including user access logs, calibration history, and deviation alerts. All test events—including start/stop timestamps, flow anomalies, and door-open interruptions—are timestamped and stored in non-volatile memory for ≥12 months. Remote monitoring via Ethernet or RS-485 is supported for integration into centralized lab management systems (LIMS).

Applications

• Validation of IP rating claims for lighting fixtures (e.g., streetlights, tunnel lamps, aviation obstruction lights)
• Pre-certification testing of automotive components including front/rear lamps, sensor housings, and ADAS modules per SAE J1211 and ECE R112
• Quality assurance of outdoor-rated industrial IoT gateways, solar inverters, and telecom junction boxes
• Reliability screening of military-grade connectors and portable field equipment per MIL-STD-810H Method 506.6
• Research on hydrophobic coating durability and sealant aging under cyclic wet-dry exposure

FAQ

What IP ratings can be validated using the QJSCY-1215?
The chamber supports full validation of IPX1 through IPX6 test conditions per IEC 60529, including vertical drip (IPX1), tilted enclosure testing (IPX2), oscillating tube (IPX3), splashing water (IPX4), and powerful jet (IPX5/IPX6) with optional wind assist.
Is temperature control integrated into the standard configuration?
No—temperature regulation is not included by default. However, ambient-to-60 °C heating capability can be added via optional chamber-heating module with PID-controlled stainless steel heaters and Class A PT100 sensors.
How is water quality managed to prevent nozzle clogging?
A dual-stage filtration system (5 µm sediment filter + 1 µm particulate filter) is installed upstream of the flowmeter. Deionized or softened water is recommended for continuous operation exceeding 200 hours per month.
Can test reports be generated automatically?
Yes—when equipped with RainTest Pro software, the system auto-generates PDF test reports containing operator ID, calibration status, raw flow/time data, pass/fail determination per clause, and digital signature fields compliant with ISO/IEC 17025 documentation requirements.
What maintenance intervals are recommended?
Nozzle inspection and cleaning every 50 operating hours; flowmeter recalibration annually or after 500 test cycles; full system verification per ISO/IEC 17025 every 12 months by accredited third-party service provider.
