Overview
The Jianhu JH-OZ Series Ozone Aging Test Chamber is an engineered environmental test system designed to evaluate the ozone resistance of elastomers, rubber compounds, plastics, and polymer-based cables under controlled accelerated aging conditions. Based on the fundamental principle of static or dynamic exposure to elevated ozone concentrations (typically 25–500 pphm), the chamber simulates atmospheric ozone degradation mechanisms—primarily surface oxidation leading to microcrack initiation and propagation—per ASTM D1149, ISO 1431-1, and GB/T 7762–2014. Unlike generic environmental chambers, the JH-OZ Series integrates a precision ozone generation subsystem with real-time UV absorption concentration monitoring, closed-loop feedback control, and thermally stabilized air circulation architecture to ensure spatial uniformity and temporal stability—critical for reproducible crack onset time (COT) and crack growth rate quantification in R&D and QC laboratories.
Key Features
- Stable ozone generation via high-efficiency corona discharge tube with integrated catalytic ozone destruct unit for safe exhaust compliance
- Real-time ozone concentration monitoring using dual-beam UV photometric sensor (254 nm), calibrated traceably to NIST standards
- Precise temperature control (ambient +10°C to 70°C ±0.5°C) and humidity regulation (30–80% RH ±3% RH) via PID-controlled refrigeration/heating and steam humidification
- Uniform airflow design with optimized duct geometry and adjustable axial fan speed to maintain ≤±1.5°C temperature deviation across test zone (per IEC 60068-3-5)
- Test chamber interior constructed from electropolished 316L stainless steel; door gasket certified for ozone leakage <0.1 ppm (measured per EN 14175-5)
- Optional dynamic testing configuration with programmable sample rotation or tensile strain fixtures compliant with GB/T 7762 Annex B and ASTM D1149 Method B
Sample Compatibility & Compliance
The JH-OZ Series accommodates standard dumbbell-shaped, ring, or strip specimens (per ISO 1431-1 and GB/T 7762), including vulcanized natural rubber (NR), styrene-butadiene rubber (SBR), nitrile rubber (NBR), EPDM, silicone, and halogenated polymers. Specimen holders are available in 316L stainless steel or PTFE-coated variants to prevent catalytic ozone decomposition. The system meets essential safety and performance requirements outlined in CE Machinery Directive 2006/42/EC, RoHS 2011/65/EU, and is fully compatible with GLP-compliant laboratory workflows. Full traceability documentation—including factory calibration certificates for ozone sensor and temperature/humidity probes—is provided with each unit.
Software & Data Management
Equipped with Jianhu’s proprietary OzoneControl™ v3.2 software (Windows-based), the chamber supports automated test protocol execution, real-time parameter logging at user-defined intervals (down to 1-second resolution), and export to CSV/PDF formats. Audit trail functionality complies with FDA 21 CFR Part 11 requirements when configured with electronic signature and role-based access control. Remote monitoring via Ethernet or optional Wi-Fi enables secure cloud synchronization and mobile alerting (SMS/email) for out-of-spec events. All firmware and software updates are delivered through validated release channels with version-controlled change logs.
Applications
- Accelerated evaluation of ozone resistance in automotive rubber components (hoses, seals, bushings)
- Quality assurance of wire & cable insulation materials for aerospace and rail applications
- Formulation screening of antiozonant additives (e.g., p-phenylenediamine derivatives) in synthetic rubber compounding
- Comparative aging studies supporting ISO 1431-2 (crack growth measurement) and ASTM D1149 (static crack assessment)
- Supporting regulatory submissions requiring ozone aging data under ICH Q5C (stability testing of biopharmaceutical excipients) and UL 1581 (wire flammability standards)
FAQ
What ozone concentration range does the JH-OZ Series support?
The system delivers stable ozone concentrations from 25 to 500 parts per hundred million (pphm) with ±5% accuracy over 72-hour continuous operation.
Is dynamic testing (under strain) supported out of the box?
Yes—optional motorized specimen stretch fixtures and programmable rotation stages are available as factory-installed modules, fully integrated into OzoneControl™ software scheduling.
How is ozone concentration verified during validation?
Each unit ships with a NIST-traceable calibration certificate for the onboard UV sensor, and users may perform independent verification using a portable reference ozone analyzer (e.g., 2B Technologies Model 106-M).
Does the chamber meet ISO/IEC 17025 laboratory accreditation requirements?
When operated with documented SOPs, calibrated ancillary instruments, and maintained per Jianhu’s Preventive Maintenance Schedule, the JH-OZ Series supports ISO/IEC 17025 method validation for ozone aging testing.
What is the warranty and service coverage outside China?
Jianhu provides 24-month parts-and-labor warranty, backed by authorized service partners in North America, EU, and APAC regions; on-site calibration and IQ/OQ documentation packages are available upon request.
