FEATURE	UV WEATHERING TEST CHAMBER	XENON ACCELERATED WEATHERING TEST CHAMBER	SALT SPRAY CORROSION TEST CHAMBER	OZONE TEST CHAMBER
PRIMARY PURPOSE	UV exposure aging using fluorescent UV lamps	Sunlight simulation with xenon arc spectrum	Corrosion resistance testing in controlled saline mist	Ozone degradation testing for cracking and aging resistance
BEST FOR MATERIALS	Coatings, plastics, polymers, UV-sensitive materials	Coatings, plastics, textiles, colored materials (colorfastness)	Metals, alloys, protective coatings, plated parts	Rubber, elastomers, polymers
SIMULATES	UV radiation effects and surface degradation	Natural sunlight exposure and broader weathering conditions	Salt spray / salt fog corrosion environment	High-ozone environment exposure
TYPICAL USE CASES	Discoloration, cracking, gloss loss, material weakening	Photodegradation, color change, durability and aging behavior	Coating performance and corrosion resistance validation	Cracking resistance and ozone durability evaluation
COMMON DECISION DRIVER	Need UV-focused accelerated aging	Need broad-spectrum light simulation closer to real sunlight	Need corrosion testing rather than light aging	Need ozone exposure rather than UV or corrosion methods
SELECTION TIP	Choose if UV degradation is your primary concern	Choose if sunlight spectrum simulation is required for your method	Choose if corrosion resistance is the primary requirement	Choose if rubber or elastomer ozone cracking is the key failure mode
