Importance of Testing in Automotive Industries
Ensuring every component-from engine blocks to electronic modules-performs reliably under the harshest driving conditions is non‐negotiable in today's competitive automotive market. LIB's environmental test chambers condense years of real‐world aging and stress into accelerated laboratory cycles, verifying that brake systems, powertrains, plastics, paint finishes, and electronics meet or exceed global OEM and regulatory requirements.
Automotive Industry is a highly competitive and progressive industry all across the globe.To survive in the market for a long period of time,automotive industries need to be constantly innovative in terms of quality,durability,etc.Also,the manufacturers of vehicles need to ensure that the system and components of the automobiles must function properly throughout their working life.Although the environment which the automobiles bear in a year or year after year changes frequently,engineers need to make use of highly sophisticated and innovated test applications to enhance the performance of newly launched products in highly effective and modern way.
Automotive Testing Equipment LIB Support
Temperature & Humidity Test Chambers
Profile: Precise control from –70 °C to +150 °C (± 0.5 °C) and 20 %–98 % RH (± 2.5 % RH), leveraging robust compressors and Nichrome‐alloy heaters.
Automotive Focus: It validates electronic control unit (ECU) operation during extreme temperature and humidity swings and ensures the reliability of the climate-control system. It also assesses interior material aging, protecting against foggy windshields and brittle dashboard trims after years of service.
(1) 2-Zone Rapid-Transfer Cycling
Profile: –40 °C ↔ +120 °C in under 3 s, with programmable dwell times (e.g., 30 min hot/30 min cold).
Automotive Focus: Detects micro‐cracks in engine control boards, gauges solder‐joint resilience, and checks connector integrity to prevent intermittent failures in anti‐lock braking or advanced driver‐assist systems (ADAS). Conforms to ISO 16750‐4 thermal shock requirements.
(2) 3-Zone Air-Circulation Cycling
Profile: Sequential cold-hot-cold transitions with ≤ 5 min recovery to set‐points.
Automotive Focus: Assesses the seal durability of headlamps and sensor housings, verifies strain‐relief on wiring harnesses, and confirms gasket performance after repeated environmental shocks.
Salt Spray & Cyclic Corrosion Test Chambers
Profile: Continuous fog per ASTM B117 and ISO 9227; cyclic salt‐mist per IEC 60068-2-11 with optional SO₂ at 25 ± 5 ppm and 75 ± 5 % RH.
Automotive Focus: Evaluates under‐body coatings, fastener corrosion resistance, and electronic module enclosures against road‐salt and industrial pollutants-ensuring long‐term structural integrity and preventing recall risks.
Mixed Flowing Gas (MFG) Chambers
Profile: Simultaneous exposure to H₂S, NO₂, Cl₂ following IEC 60068-2-60.
Automotive Focus: Simulates urban smog and acidic gas exposure for emission system components and oxygen sensors, validating corrosion protection on critical exhaust and fuel‐delivery parts.
(1) Xenon Arc Aging
Profile: Full solar‐spectrum 280–800 nm, lamp life 1,600 h, reproducing years of solar exposure in weeks.
Automotive Focus: Tests paint and clearcoat durability against fading, chalking, and cracking; verifies UV‐stabilizer performance in polymer bumpers, seals, and interior fabrics.
(2) UV Accelerated Weathering
Profile: Focused 290–400 nm ultraviolet spectrum, lamp life 5,000 h.
Automotive Focus: Rapidly evaluates windshield‐adhesive aging, dashboard surface resistances, and sealant color stability-safeguarding vehicle aesthetics and cabin comfort.
Ingress Protection Test Chambers
Water Spray & Immersion Test Chambers
Profile: IPX1–IPX2 drip tests; IPX3–IPX4 oscillating‐spray; IPX5–IPX6 high‐pressure wash; IPX7–IPX8 immersion up to 1 m–50 m; IPX9K angled‐wash at 88 °C/8000–10000 kPa.
Automotive Focus: Verifies ECU housings, LED headlamp assemblies, and sensor modules for seal integrity against road grime, power‐wash procedures, and submersion events-crucial for off‐road and high‐rainfall applications.
Sand & Dust Test Chambers
Profile: IEC 60529/ISO 20653 and MIL-STD-810G Method 510 simulations of desert and industrial particulates.
Automotive Focus: Assesses air‐intake filters, HVAC vents, and seat‐track mechanisms to prevent clogging and ensure consistent cabin air quality and component operation in dusty environments.
