Water Spray Test Chamber – Century Series

The Auto Technology Century Series Water Spray Test Chamber is configurable for controlled rain, shower, oscillating spray, and high-pressure wash exposures. Spray apparatus, water conditions, specimen motion, and controls are selected for the applicable component and procedure.

  • High-Pressure Spray: Four independently controlled nozzles; 400-1,500 psi with water temperatures up to 80°C in the documented heated-water configuration
  • Rain and Spray Systems: JIS D 0203 apparatus and a 21-nozzle stainless-steel oscillating arc
  • Specimen Motion: Variable-speed rotating platform with optional reversing, slip-ring power, and air feed
  • Control Options: Basic controls or programmable PLC and touchscreen sequencing

Capability depends on the selected nozzles, pressure, flow, water temperature, geometry, motion, controls, and calibration package. The current procedure must be reviewed before a standards-specific configuration is defined.

Description

Water Spray Test Chamber for Rain and Water Ingress Testing

The Auto Technology Century Series Water Spray Test Chamber provides a controlled enclosure for evaluating housings, seals, connectors, lighting products, vehicle components, and other assemblies exposed to water during service or cleaning. This rain and water ingress test chamber can be configured for shower, oscillating spray, fixed-nozzle spray, or high-pressure wash exposures.

The applicable spray apparatus, water pressure, flow, temperature, nozzle geometry, specimen position, motion, and control sequence are selected around the test item and procedure rather than forcing every application into one fixed chamber arrangement.

Procedure-specific configuration: A standards reference does not mean every Century chamber performs every procedure or protection level. The current method and required nozzle, flow, pressure, water temperature, distance, specimen motion, calibration, and reporting requirements must be reviewed before the chamber is configured.

Rain, Spray, and High-Pressure Water Test Systems

High-Pressure Spray

Four independently controlled nozzles apply high-pressure water from adjustable positions. Each nozzle can be assigned a separate timed step with the automated-control package.

  • 400-1,500 psi documented pressure range
  • Water temperature up to 80°C in the documented configuration
  • Adjustable nozzle position and specimen distance
  • Removable rack and quick-disconnect construction

Oscillating Spray Arc

The stainless-steel arc applies water through 21 removable nozzles directed toward the center of the specimen platform. Arc motion and spray can be programmed independently.

  • Automatically reversing motion at adjustable speeds
  • Twenty-one removable nozzles
  • Dual quick-disconnect unions
  • 30-145 psi documented pressure capability

JIS D 0203 Rain Test Chamber

The JIS apparatus provides the rain and spray distributions used by the R1, R2, S1, and S2 procedures while the arm rotates on a 45-degree axis.

  • R1/R2 rain configuration
  • S1/S2 spray configuration
  • Arm rotation from 0 to 23 RPM
  • Quick-change installation and equipment-detection interlock

Custom Fixed-Nozzle Spray

Fixed-nozzle systems can be arranged for component-specific spray angles, distances, and coverage. Documented Century options include a 45-degree spray arrangement developed for SAE J575-type applications.

  • Component-specific nozzle positioning
  • Custom spray racks and specimen fixtures
  • Stationary or rotating specimen exposure
  • Procedure-specific pressure, flow, and nozzle selection

Specimen Motion and Powered Testing

The rotating platform exposes different sides of the specimen without stopping the procedure for manual repositioning. Platform speed is adjustable, and automatic reversing can be added when the specimen or test method requires alternating motion.

  • Variable-speed rotation from 0 to 17 RPM
  • Optional automatic reversing
  • Optional slip-ring assembly for electrical power on the rotating platform
  • Optional air feed to the top of the platform
  • Programmable user output for energizing or cycling components during exposure

Platform diameter, allowable load, fixture design, and utility connections are defined for the intended test item.

Programmable Controls and Test Sequencing

Century chambers can be supplied with basic ON/OFF controls or an automated PLC and touchscreen package. Automated configurations support stored procedures and custom multi-step sequences.

Control function Documented capability
High-pressure spray Independent event control for each of the four nozzles
Timing Programmable interval time, including seconds-based spray events
Water temperature Programmable heated-water tank setpoint
Motion Spray-system motion and specimen-platform control
Custom procedures Multi-step profiles with loops and configurable user outputs
Access and documentation Password-protected programming and calibration screens; optional data output

Intended Standards and Procedure Types

Standard or procedure family Century Series application
JIS D 0203 R1, R2, S1, and S2 Automotive-component rain and spray exposure using the dedicated rotating JIS apparatus
IEC 60068-2-18 Applicable water-test procedures using an oscillating spray arc or other required apparatus
IEC 60529 Selected water-ingress procedures when the required nozzle, flow, pressure, distance, and specimen arrangement are included
ISO 20653 and DIN 40050-9-type procedures Vehicle-component water-ingress and high-pressure wash exposures when specifically engineered and validated for the selected protection level
SAE J1455 Heavy-duty vehicle environmental spray procedures using the applicable pressure, flow, temperature, and specimen arrangement
SAE J575-type applications Lighting-device spray exposure using the documented optional 45-degree nozzle arrangement
Customer and legacy automotive procedures Custom rain, spray, shower, or high-pressure wash configurations, including equipment historically developed for GM 9103P

Older Century documentation uses the former designations IEC 68-2-18 and IEC 529. Current quotations should identify the applicable current standard, edition, procedure, and protection level.

Water Handling, Construction, and Safety

  • Recirculating water reservoir with in-line particulate strainers
  • Accessible pressure and flow adjustments
  • PVC, CPVC, or stainless-steel hydraulic construction selected for the specified conditions
  • Front-opening viewing door with interlocks that pause spray and heating functions when opened
  • High-temperature shutdown protection for the chamber and heated-water tank
  • Low-water protection for the heater and pumps
  • Equipment-detection interlocks for the installed spray apparatus
  • Blast shielding for high-pressure operation
  • Chamber vent connection for facility exhaust

High-pressure protection testing: The documented 400-1,500 psi pressure range and 80°C heated-water capability do not by themselves establish compliance with ISO 20653 or an IP protection level. Flow rate, nozzle type and force, spray angles, distance, exposure time, specimen rotation, instrumentation, and calibration must also satisfy the current procedure.

Information Required for Configuration

Provide the current standard or customer procedure and the following information when requesting a Century Series configuration:

  • Maximum specimen dimensions and weight
  • Required spray direction, nozzle distance, and coverage
  • Required water pressure, flow, and temperature
  • Required specimen rotation or other motion
  • Electrical, pneumatic, or signal connections needed during exposure
  • Control, recording, reporting, and calibration requirements
  • Facility voltage, water, drain, and exhaust conditions

Specify the standard and revision, procedure or protection level, specimen dimensions and weight, required spray conditions, motion, powered-operation needs, documentation requirements, and available utilities when requesting a Century Series Water Spray Test Chamber.
