Complete Cable Testing Capabilities with LIB Ozone Test Chambers

LIB Ozone Test Chambers provide exactly that-fast, precise, and standards-compliant cable testing in one robust platform.

【How LIB Ozone Test Chambers Conduct Cable Testing and the Key Advantages】

To evaluate cable durability accurately, ozone exposure must replicate real-world conditions while applying the same mechanical strain that cables experience in service. LIB chambers achieve this through a combination of advanced control and mechanical flexibility:

Realistic Ozone Aging
The chamber can produce ozone concentrations from 1–1000 PPHM, adjustable to match both IEC 60068-2-42 and Volkswagen PV3305 requirements. For example, rubber cable jackets can be tested at 2 ppm ozone (±15 %), 40 °C (±3 °C), and 55 % RH (±5 %) for 48 hours to simulate accelerated aging as described in PV3305.

Dynamic and Static Stress Simulation
Samples can be mounted on static clamps or on a rotating sample holder operating at 0–10 r/min, with elongation from 5 %–35 %. This reproduces bending, twisting, or stretching that occurs during real cable use, ensuring results predict true service performance.

Integrated Environmental Control
Temperature ranges from 0–100 °C and humidity from 30–98 % RH are tightly regulated using a PID color touchscreen controller. Embedded sensors continuously measure ozone, temperature, and humidity, ensuring repeatability and compliance with strict standards.

Safety and Environmental Responsibility
A silent-discharge ozone generator and activated carbon filtration neutralize residual ozone before venting. This protects both operators and the environment while meeting ISO 14001 environmental protection requirements.

In short, LIB's ozone chambers provide engineers with accurate, repeatable, and globally recognized test results that accelerate product development and strengthen quality assurance programs. Learn more at Ozone Test Chamber.pdf

【LIB's Successful Customization Cases for Cable Testing Under Different Standards】

LIB understands that not all cables or standards require the same setup. By working closely with manufacturers, LIB delivers customized sample-holder designs that simplify complex tests and improve accuracy. Examples include:

Core Spindle on Static Holder
Designed for measuring cable durability when wrapped around a spindle positioned above a static clamp. This configuration makes winding easy and ensures even ozone exposure.

Dual-Layer Sample Rack
The lower layer rotates, while the upper layer holds a core spindle. This hybrid design allows simultaneous testing of both fixed and wound cable samples, maximizing chamber utilization.

Core Spindle on Combined Dynamic/Static Holder
For scenarios requiring cables to be both wound and simultaneously stretched or rotated, this configuration enables highly realistic stress profiles.

...

Each configuration supports strict elongation levels such as 5 % ± 1 %, 10 % ± 1 %, 20 % ± 2 %, 40 % ± 2 %, up to 80 % ± 2 %, in full alignment with IEC 60068-2-42 and PV3305, ensuring test results are accepted worldwide.

【LIB Maintenance Recommendations for Ozone Test Chambers and One-Stop Service】

To keep chambers operating at peak performance, LIB recommends:

Routine Checks: Replace activated carbon filters, verify ozone sensors, and inspect seals every 6–12 months depending on usage.

Calibration: Temperature, humidity, and ozone sensors should be calibrated annually to maintain compliance with international standards.

Operator Safety: Always confirm exhaust systems are functioning before starting tests.

LIB supports every chamber with a 3-year warranty and lifetime service. If a problem cannot be resolved remotely, LIB will ship a replacement chamber free of charge. With 24-hour English-speaking technical support and global spare-parts logistics, customers can depend on uninterrupted testing capabilities worldwide.
