Tower Type UV Aging Test Chamber

0.35–1.20W/m²/nm @ 340 nm 0.30–1.15W/m²/nm @ 313 nm 0.38 m²Total effective exposure area 50 ± 3 mmLamp axis to specimen plane CSV exportConfigurable data interval Why the tower architecture matters A fixed exposure geometry built for repeatable flat-specimen testing. The chamber positions removable specimen frames on two inclined exposure sides. The mounting angle is fixed by the tower structure, while the target specimen plane is maintained 50 ± 3 mm from the lamp center axis. Choose this architecture when the laboratory primarily tests standardized flat panels and needs high specimen throughput in a compact footprint. Large finished products and irregular three-dimensional parts require a fixture and exposure-geometry review before quotation. Two exposure sidesFour lamps and two irradiance sensors are arranged…

Box-Type UV Accelerated Weathering Test Chamber

The DX-H302-2 places finished parts, thick specimens and irregular shapes directly on an adjustable perforated shelf. Eight lamps are mounted in one row above the working zone, while four movable irradiance sensors follow the selected specimen-plane height. Direct horizontal loading Place specimens on the shelf without cutting every sample into a standard panel size. Adjustable exposure height Fixed shelf slots allow the test surface to be positioned…

Key Technical Parameters for Choosing a Xenon Aging Test Chamber

At Dexiang, as a professional environmental test chamber manufacturer, we’ve seen labs waste years on data that couldn’t be repeated because the wrong chamber was chosen. This article is designed to help you avoid that mistake and give you a clear, engineer-level checklist for selecting the right xenon arc weathering test chamber for 2026 and beyond. If you’re looking at buying a xenon aging test chamber, you’ve probably noticed something: every supplier claims their system offers “stable irradiance,” “accurate temperature,” and “standard-compliant” performance. But which technical parameters actually matter for your materials, standards, and budget? In this guide, you’ll see exactly which specs you must evaluate before you sign a PO: from xenon lamp type and power, to irradiance range and control accuracy, to filter systems, black panel temperature,…

UV WEATHERING SELECTION

Configure the UV exposure around the material, failure mode and test method.

A UV aging chamber combines fluorescent ultraviolet exposure with controlled condensation or water spray. The correct configuration starts with the required method—not the cabinet appearance alone.

Test method

Confirm the exact ASTM, ISO, IEC or customer procedure and edition.

Material & failure

Define fading, gloss loss, chalking, cracking, yellowing or embrittlement.

Specimens

Provide dimensions, quantity, exposed area, thickness and mounting direction.

Exposure cycle

State lamp type, irradiance, UV duration, condensation, spray and temperature.

WHAT THE SYSTEM CONTROLS

Reproduce the stresses that drive accelerated UV weathering.

UV radiation

Select the lamp family and control irradiance at the wavelength required by the method.

Condensation

Controlled moisture and specimen temperature reproduce dew-type wetting conditions.

Water spray

Optional spray supports procedures that require thermal shock, erosion or direct wetting.

Temperature

UV and moisture stages may require different chamber or panel temperature controls.

Cycle sequencing

Program the ordered UV, dark, condensation and spray stages required by the procedure.

Exposure records

Confirm the parameters, alarms and data that must be recorded for your laboratory workflow.

MATERIALS & FAILURE MODES

Use UV exposure when fluorescent lamps match the degradation question.

Typical programs evaluate coatings, plastics, sealants, roofing products, adhesives, cable materials, textiles and other non-metallic materials. Suitability depends on the method and the material's spectral sensitivity.

Coatings and paintsColor change, gloss loss, chalking and cracking

Plastics and polymersYellowing, embrittlement and surface degradation

Sealants and adhesivesCracking, loss of adhesion and visual change

Wire and cable materialsJacket deterioration and property retention

UV OR XENON ARC?

Choose by spectral requirement and exposure method.

Fluorescent UV and xenon arc systems are not interchangeable simply because both accelerate weathering. The governing method, spectral region, moisture cycle and target failure mode determine the appropriate equipment.

Choose UV when

The specified fluorescent lamp and condensation or spray cycle reproduce the required degradation mechanism.

Choose xenon arc when

The procedure requires filtered full-spectrum solar simulation, lightfastness evaluation or more complete spectral reproduction.

STANDARDS-ORIENTED SELECTION

A standard number is the starting point—not the complete chamber specification.

Always confirm the exact edition, apparatus clause, lamp requirement, exposure cycle, specimen mounting and evaluation procedure.

ASTM G154Fluorescent UV exposure of nonmetallic materials

ISO 4892-3Plastics exposed to fluorescent UV lamps

ASTM D4329Fluorescent UV exposure of plastics

ASTM D4587Fluorescent UV-condensation exposure of coatings

ISO 16474-3Paints and varnishes exposed to fluorescent UV lamps

UV CHAMBER FAQ

Questions to resolve before selecting a chamber.

Which UV lamp should I choose?

Use the lamp required by the governing method or validated internal procedure. Do not select a lamp only because it produces faster visible change.

Do I need water spray as well as condensation?

Only when the procedure or failure mechanism requires direct spray, erosion, rapid cooling or an additional wetting stage.

What specimen information is required?

Provide dimensions, thickness, quantity, exposed area, mounting orientation, masking requirements and any special holder needs.

Can one chamber cover every UV standard?

No universal configuration should be assumed. Lamp, irradiance, temperature, moisture, mounting and cycle requirements must be checked method by method.

Can fixtures and chamber access be customized?

Application-specific holders, ports and access arrangements can be reviewed after receiving specimen drawings and the required exposure geometry.
