Product Reliability Testing

Product Reliability Testing

Product reliability testing is a critical process that verifies whether a product can maintain its functional stability and structural integrity under various stress conditions throughout its expected service life. The test scope simulates extreme environments, including temperature cycling, high temperature and humidity, salt spray, vibration, shock, drop, IP dust and water resistance, IK mechanical impact, and UV exposure, to evaluate the product’s weather resistance, durability, and environmental adaptability. Such testing is widely applied to products with stringent reliability requirements — including electronic devices, outdoor equipment, lighting fixtures, transportation infrastructure, military-grade instruments, and industrial equipment — ensuring stable operation even under harsh conditions.

Reference Cases

• Lighting Fixtures: Outdoor streetlights underwent accelerated aging and environmental durability testing, including CNS 3634 high temperature and humidity tests, ISO 9227 salt spray, and EN 60529 IP protection tests, to verify weather and corrosion resistance under harsh environmental conditions. These luminaires are ideal for lighting applications in coastal bridges and high-humidity, high-salinity environments.
• Home Appliances: A clothes dryer was tested under IEC 60068 temperature cycling and solenoid valve endurance testing to verify component reliability under thermal stress and long-term operation. Results confirm overall performance stability and compliance with extended warranty quality standards.
• ICT Products: An industrial-grade router passed IEC 60068 vibration and mechanical shock simulations as well as high-temperature continuous operation testing, verifying its structural durability and operational stability under high-stress conditions. It is suitable for automotive communication systems and other applications exposed to high temperatures and frequent movement.
• Explosion-Proof Electrical Equipment: An explosion-proof junction box designed with an Ex d IIB flameproof structure and IEC 60529 IP66 rating passed IEC 60079-1 explosion-proof testing, ASTM B117 salt spray, and IEC 60068 humidity and heat resistance tests. It withstands corrosive coastal environments with high salinity and humidity, and meets Class / Division / Zone safety requirements. Certified under IECEx and CNS, it has been successfully implemented in multiple petrochemical, gas station, and heavy industrial coastal installations with stable long-term operation.
• Fire Protection Equipment: An emergency lighting fixture featuring a waterproof and dustproof reinforced enclosure and weather-resistant optical materials passed IEC 60068 thermal-humidity cycling, CNS 8886 salt spray, and ASTM G154 UV aging tests, and meets EN 60529 IP65 and IEC 62262 IK08 standards. It ensures reliable activation and continuous performance in outdoor environments exposed to sunlight, rain, and salt corrosion, and is now widely used in parking exits, open-air transport hubs, and coastal public facilities requiring high weather resistance.
