Overview
The OK-CY Series Ozone Aging Test Chamber is an engineered environmental test system designed to evaluate the ozone resistance of elastomeric materials—including natural rubber, SBR, CR, EPDM, and silicone compounds—under controlled, reproducible atmospheric conditions. It operates on the principle of accelerated aging via exposure to precisely regulated ozone concentrations in a sealed, recirculating gas loop. Unlike open-air or semi-closed systems, this chamber employs a fully enclosed silent discharge ozone generator coupled with a nondispersive ultraviolet (UV) absorption ozone analyzer, enabling real-time, trace-level quantification (50–1500 pphm) with long-term stability and minimal drift. The chamber’s thermal and humidity control architecture—featuring PID auto-tuning, high-resolution Weilun touchscreen interface, and Siemens S7-1200 PLC logic—ensures stable operation within ±0.5 °C temperature fluctuation and 30–65 %RH humidity range, critical for isolating ozone-induced surface cracking from confounding thermal or hygroscopic effects.
Key Features
- Hermetically sealed ozone generation and circulation loop: eliminates operator exposure and ensures consistent gas-phase kinetics across test cycles.
- Adjustable ozone concentration control (50–1500 pphm) via digital feedback loop; calibrated output signal (4–20 mA) and RS232 serial interface support integration into centralized lab data acquisition networks.
- Dynamic sample exposure capability: motor-driven 360° rotating sample rack (1 rpm), engineered to follow cycloidal trajectory per ISO 1431-1 Annex B requirements for uniform strain distribution during static or dynamic testing.
- UV-based ozone sensor with ≥5-year operational lifetime and built-in metrology port for periodic NIST-traceable calibration verification.
- Dual-parameter PID control system managing simultaneous setpoint regulation of ozone concentration, temperature, and relative humidity—with independent auto-tuning for each variable.
- Comprehensive safety architecture: integrated leakage detection, overtemperature cutoff, motor overcurrent protection, short-circuit isolation, and grounded discharge shielding compliant with IEC 61000-6-3 EMC standards.
Sample Compatibility & Compliance
The OK-CY chamber accommodates standard dumbbell, strip, and ring specimens per ASTM D1149 and ISO 1431-1 protocols. Its modular internal dimensions (40×50×40 cm to 100×100×100 cm) allow customization for large-format components such as automotive seals, cable jackets, or conveyor belts. All models are validated against national and international standards including GB/T 7762–2003 (Chinese national standard for rubber ozone resistance), GB/T 2951.21–2008 (cable insulation testing), GB/T 11206–2009 (rubber physical property evaluation), and ISO 1431-1:2004 (determination of ozone cracking resistance under static and dynamic conditions). The sealed-loop design meets GLP documentation requirements for auditability, and its analog/digital outputs support 21 CFR Part 11–compliant electronic record retention when paired with validated LIMS or ELN platforms.
Software & Data Management
Control firmware supports time-stamped logging of ozone concentration, chamber temperature, humidity, and elapsed exposure duration at user-defined intervals (1 sec to 60 min resolution). Data export is available via USB flash drive or RS232 serial link in CSV format, compatible with MATLAB, Python pandas, and statistical process control (SPC) software. The Weilun HMI provides intuitive alarm history review, parameter trend graphs, and password-protected configuration access levels (operator, technician, administrator). Optional OPC UA gateway enables seamless connectivity to MES or SCADA environments for Industry 4.0 integration.
Applications
- Quality assurance of rubber compounds in tire, hose, gasket, and sealing element manufacturing.
- R&D screening of antioxidant and antiozonant additive efficacy in synthetic elastomer formulations.
- Validation of material substitutions under regulatory change control (e.g., REACH, RoHS-compliant alternatives).
- Failure analysis of field-failed components exhibiting ozone-induced surface fissuring.
- Supporting ISO/IEC 17025 accredited testing laboratories requiring documented uncertainty budgets and inter-laboratory comparison readiness.
FAQ
Does the chamber support both static and dynamic ozone exposure modes?
Yes—standard configuration includes a continuously rotating sample rack (1 rpm, 360°); optional static fixtures are available for non-rotating tensile strain applications.
Is ozone concentration measurement traceable to national standards?
Yes—the UV absorption sensor includes a dedicated metrology port for third-party calibration using NIST-traceable ozone transfer standards.
Can the system be integrated into an existing laboratory network?
Yes—RS232 communication port and 4–20 mA analog outputs enable connection to PLC-based monitoring systems or custom LabVIEW DAQ interfaces.
What maintenance is required for the ozone generator?
The silent discharge tube requires no consumables; annual inspection of electrode alignment and cooling airflow is recommended to maintain optimal ozone yield and minimize nitrogen oxide byproducts.
Is the chamber suitable for GMP-regulated environments?
When operated with validated SOPs and paired with audit-trail-enabled data capture software, the OK-CY series meets baseline requirements for GMP Annex 11 and FDA 21 CFR Part 11 compliance.
