Sunlight, rain, humidity, and temperature fluctuations are among the most damaging factors materials face outdoors, causing fading, cracking, chalking, embrittlement, and loss of strength over time. LIB accelerated weathering solutions compress months or years of outdoor exposure into days or weeks of lab testing.
Reproduce full-spectrum sunlight, UV, moisture, and combined weathering-corrosion conditions to evaluate coatings, plastics, textiles, and solar components — meeting ASTM, ISO, and SAE international standards.

LIB provides environmental simulation solutions for the following weathering-related tests:
Xenon Arc Weathering Test
Xenon arc testing uses a xenon lamp to reproduce the full spectrum of sunlight, including UV, visible, and infrared light, combined with controlled temperature, humidity, and water spray. It is widely regarded as the closest laboratory simulation to natural sunlight.
Common standards:
· ASTM G155
· ISO 4892-2
· SAE J2527
· SAE J1960
Solar Simulation Test
Solar simulation testing reproduces concentrated sunlight conditions to evaluate thermal and optical performance, commonly used for solar panels, automotive components, and outdoor electronics.
Common standards:
· IEC 60068-2-5
· ISO 4892 series
|
|
What you're afraid of: a coating that fades or chalks within a year outdoors A coating or plastic that looks fine after a quick indoor check can still fade, crack, or chalk within a single outdoor season once real sunlight gets to it. This xenon arc chamber reproduces the full solar spectrum with adjustable irradiance and programmable light/dark and spray cycles, so degradation shows up in weeks of testing instead of a year of field complaints. Irradiance 0.35–1.10 W/m² @340nm · 35℃~85℃ black panel · 50–98% RH |
UV Weathering Test (Fluorescent UV / QUV)
UV weathering testing uses fluorescent UV lamps to simulate the short-wavelength UV portion of sunlight, combined with condensation cycles to simulate dew and moisture exposure. It is commonly used for materials most sensitive to UV degradation.
Common standards:
· ASTM G154
· ISO 4892-3
Light Fastness / Color Fastness Test
Light fastness testing evaluates the resistance of dyed or printed materials, such as textiles and inks, to fading or color change when exposed to light sources.
Common standards:
· ISO 105-B02
· AATCC 16
|
What you're afraid of: colors fading or fabrics degrading faster than promised Textiles, inks, and UV-sensitive plastics that fade or degrade faster than a warranty promises turn into customer complaints and returns. This chamber runs UVA-340 or UVB-313 lamps at up to 1.55 W/m² with condensation and spray cycles, reproducing years of UV and moisture exposure on a programmable cycle you control. Up to 1.55 W/m² @340nm · Chamber temp up to +90℃ · Condensation + spray cycles Replacement component: UVA-340 fluorescent lamp, peak wavelength 340nm, closely matches natural sunlight UV spectrum below 365nm. |
Carbon Arc Weathering Test
Carbon arc testing is an earlier weathering simulation method that uses a carbon arc light source to reproduce sunlight exposure, still referenced in some legacy industry standards.
Common standards:
· ASTM G152
· ASTM G153
|
|
What you're afraid of: a report that doesn't satisfy an older spec still on file When a customer or legacy spec still calls out ASTM G152/G153 by name, a modern xenon report alone may not satisfy the requirement, and re-testing after the fact costs time you don't have. This chamber runs enclosed or open-flame carbon arc exposure with water spray cycling, built specifically to keep legacy-standard compliance available when it's still requested. Enclosed or open-flame carbon arc · Water spray cycle · Complies with ASTM G152/G153 |
|
Combined Weathering and Corrosion Test
Many outdoor products face both UV exposure and corrosive environments simultaneously, such as coastal or industrial regions.
Applicable standards:
· ASTM G155
· ISO 4892 series
· Combined salt spray and UV cyclic standards
|
|
What you're afraid of: a coating that passes UV testing but fails once salt gets involved A coating that survives isolated UV exposure can still fail once combined with salt spray in the real coastal or industrial environments it's actually sold into. This chamber runs short-duration UV pre-aging cycles programmed to OEM specification, then hands the sample to a cyclic corrosion chamber, so both stresses are validated in sequence instead of assumed independently. UVA-340 lamps · Programmable per OEM spec · Temp/humidity control included Pairs with a cyclic corrosion test chamber for the full combined weathering-corrosion sequence — see our Corrosion Testing Solutions page. |
Large-Scale / Custom Weathering Test
Application-dependent
Full-size panels, large assemblies, and high sample volumes often exceed the capacity of standard benchtop weathering chambers, requiring a dedicated large-format testing space.
|
|
What you're afraid of: full-size panels that can't fit any chamber you own Building panels, large automotive assemblies, and bulk sample batches simply don't fit in a standard chamber, forcing manufacturers to cut samples down or outsource testing entirely. This room-scale chamber is custom-built from several cubic meters up to a full room, with multiple light source arrays for uniform exposure across the whole space. Custom volume: several m³ to full-room scale · Multiple light arrays · Custom monitoring available |

FAQ — Frequently Asked Questions
| Which weathering test standard applies to my product? | It depends on your material and industry. Use the standard selector table above, or contact our engineers — we'll match your product to the correct ASTM, ISO, or SAE standard based on your application and any customer or OEM requirements you already have on file. |
| What's the difference between xenon arc and UV testing? | Xenon arc reproduces the full solar spectrum (UV, visible, infrared) and is the closest lab simulation to real sunlight — commonly required for automotive and solar applications. UV/QUV testing focuses on the short-wavelength UV portion of sunlight and is typically used for plastics, coatings, and building materials where UV degradation is the primary concern. |
| Can your equipment meet standards not listed on this page? | Most of our chambers are programmable and can be configured to additional or customer-specific test standards. Let us know your required standard and we'll confirm compatibility. |
| How long does a typical weathering test take? | Test duration depends on the standard, material, and target exposure equivalent (e.g., simulated years of outdoor exposure). Most accelerated tests run from a few hundred to a few thousand hours; our engineers can estimate a timeline based on your specification. |
| Do you offer calibration and replacement parts? | Yes. Consumables such as UVA-340 lamps and xenon burners are available as replacement components, and all chambers are covered under lifetime maintenance support. |
| Can equipment be customized for large or oversized samples? | Yes — for full-size panels or large assemblies that exceed standard chamber capacity, we offer walk-in weathering rooms built to custom volume, from several cubic meters up to full-room scale. |
