Filter Systems	Daylight filters for full spectrum; window glass filters to simulate real conditions; extended UV, CIRA (sodalime) filters for specific testing needs
Black Panel Temperature (BPT) vs Black Standard Temperature (BST)	Know which your test requires. BPT measures the panel temperature exposed to the light source, BST uses a standard black surface reference. This affects degradation results
Chamber Temperature & Humidity Controls	Precise temperature (often 20-80°C) and humidity control (typically 50-95% RH) ensure test repeatability and match various standard methods
Specimen Handling	Look for spray systems, specimen rotation, and rack types that match your sample size and improve exposure uniformity

Quick tips:

• Water-cooled lamps usually offer more stable irradiance but cost more upfront.
• Air-cooled lamps are simpler and cheaper but can have more fluctuations.
• Always verify the test chamber comes with filter options aligned to your standard (e.g., ASTM G155 uses daylight filters).
• Don’t forget calibration certificates to confirm irradiance and temperature accuracy.
• Ensure the spray system mimics real weathering (rain/dew cycles) if your test standard requires it.

Getting these technical parameters right upfront saves headaches later and ensures your xenon arc testing meets North American and international standard expectations.

Common Compliance Pitfalls Buyers Face (and How to Avoid Them)

When shopping for a xenon lamp aging test chamber, avoiding some common mistakes can save you time and money:

• Beware of Cheap Models Meeting Only ISO 4892-2 Method AMany low-cost chambers claim compliance but only cover the basic ISO 4892-2 Method A for plastics. These often fall short when it comes to the tighter controls and precision needed for automotive or high-end coatings testing. If you’re working with automotive standards like SAE J2412 or ASTM G155, make sure the chamber meets those specific requirements.
• Confusing Air-Cooled vs Water-Cooled Xenon Lamp PerformanceAir-cooled lamps are common and simpler, but they may offer less stable irradiance and shorter lamp life. Water-cooled lamps provide better temperature control and longer durability, especially for 4.5 kW or higher lamps. Knowing the difference helps you pick a chamber that fits your test cycle and maintenance capabilities.
• Missing Third-Party Calibration CertificatesCalibration is critical for reliable results. Always ask for third-party calibration certificates from accredited labs like UKAS, DAkkS, or CNAs. Without these, your test data could be off, especially when you need to prove compliance for automotive or coating certification.

To stay compliant and get trustworthy results, verify these points upfront. It’s better to invest in a capable xenon tester that ticks all the boxes than save upfront and face costly retests later.
