Jianhu Jiangsu Ozone Aging Test Chamber JH-OZ-300

Overview

The Jianhu Jiangsu Ozone Aging Test Chamber JH-OZ-300 is an engineered environmental test system designed to evaluate the ozone resistance of elastomeric materials—particularly vulcanized rubber compounds—under controlled, accelerated aging conditions. It operates on the principle of dynamic or static exposure to precisely regulated ozone concentrations (typically 25–200 pphm), elevated temperature (room temperature to +70 °C), and optionally stabilized relative humidity (10–80% RH), in accordance with international standards including ASTM D1149, ISO 1431-1, GB/T 7762, and JIS K 6259. The chamber utilizes a corona discharge ozone generator coupled with catalytic decomposition and real-time UV absorption-based ozone monitoring to ensure traceable, stable, and reproducible concentration control. Its robust stainless-steel interior, optimized laminar airflow design, and double-sealed door assembly mitigate thermal gradients and ozone leakage—critical factors directly impacting test validity and inter-laboratory comparability.

Key Features

• UV-absorption ozone sensor with NIST-traceable calibration, enabling continuous real-time monitoring and closed-loop feedback control (±5% accuracy across 25–200 pphm range)
• Patented air circulation system featuring symmetrical dual centrifugal fans and baffle-guided laminar flow, achieving ≤±1.5 °C temperature uniformity (measured per IEC 60068-3-5) and ≤±3% RH uniformity at 50 °C/50% RH
• Interior constructed entirely from electropolished 316L stainless steel—resistant to ozone-induced pitting and metallic ion leaching, eliminating sample contamination risks
• Dual-stage sealing mechanism: high-compression silicone gasket + magnetic latching door, validated for ozone leakage <0.1 ppm at operating pressure (tested per EN 14175-3)
• Integrated safety architecture: ozone destruct catalyst, automatic power cutoff upon door opening, and redundant over-concentration alarm (audible + visual + relay output)
• Modular controller with Ethernet/Wi-Fi connectivity, supporting remote parameter adjustment, live data streaming, and event-logged audit trail compliant with FDA 21 CFR Part 11 requirements

Sample Compatibility & Compliance

The JH-OZ-300 accommodates standard dumbbell-shaped, ring-shaped, or strip specimens per ASTM D1149 and ISO 1431-1, with adjustable specimen racks fabricated from 316L stainless steel or PTFE-coated aluminum. It supports both static (non-stretched) and dynamic (mechanically strained) test modes using optional motorized extension fixtures. All operational parameters—including ozone concentration, temperature, humidity, exposure duration, and cycle sequencing—are programmable and logged with timestamped metadata. The system is fully compatible with GLP/GMP laboratory workflows and has been validated for use in regulatory submissions by third-party testing laboratories accredited to ISO/IEC 17025. Documentation includes Factory Acceptance Test (FAT) reports, calibration certificates for ozone and temperature sensors, and a full compliance dossier covering CE marking (EMC & LVD directives), RoHS, and REACH.

Software & Data Management

Jianhu’s proprietary OzoneControl™ v4.2 software provides intuitive graphical configuration of multi-step test profiles, real-time overlay of up to four parameters (ozone, temp, RH, time), and automated pass/fail evaluation against crack initiation thresholds. Raw sensor data is stored in encrypted SQLite databases with SHA-256 hashing; export options include CSV, PDF test reports (with digital signature), and XML for LIMS integration. Audit trails record all user actions—including parameter changes, manual overrides, and calibration events—with immutable timestamps and operator IDs. The system supports role-based access control (RBAC), electronic signatures, and 21 CFR Part 11-compliant electronic records retention for ≥15 years.

Applications

This chamber is routinely deployed in R&D labs and QC departments of tire manufacturers, automotive component suppliers, aerospace seal producers, and medical device firms developing silicone or EPDM-based tubing and gaskets. Typical use cases include: comparative screening of antioxidant formulations; validation of vulcanization process stability; shelf-life prediction of rubber-insulated cables under tropical storage conditions; and qualification of elastomer compatibility with ozone-rich environments (e.g., high-altitude aviation, ozone-generating industrial equipment). Its repeatability (CV <2.3% for crack onset time across 10 replicate runs) meets the stringent requirements of internal method validation protocols and external accreditation bodies such as A2LA and UKAS.

FAQ

What ozone concentration range does the JH-OZ-300 support, and how is accuracy verified?
It delivers 25–200 pphm with ±5% deviation from setpoint, verified via factory-calibrated UV absorption sensor and supported by optional annual third-party calibration using certified ozone standard gas (NIST SRM 2692).
Is temperature and humidity uniformity independently validated?
Yes—each unit undergoes 24-hour uniformity mapping per IEC 60068-3-5 using 9-point thermocouple/psychrometer array; final report included with shipment.
Can the chamber operate unattended for extended durations (e.g., 168-hour tests)?
Fully supported: auto-recovery after power interruption, email/SMS alerts on fault conditions, and 30-day local data buffering ensure uninterrupted test integrity.
Does Jianhu provide installation qualification (IQ) and operational qualification (OQ) documentation?
Yes—customizable IQ/OQ/Performance Qualification (PQ) packages are available, aligned with ISO 13485 and GMP Annex 15 guidelines.
What is the warranty coverage and service response commitment?
Standard 24-month parts-and-labor warranty; 2-hour remote diagnostics SLA and 48-hour on-site engineer dispatch (excl. remote regions) under signed service agreement.
