    HWP05-20S Oxidizing Solids Tester
     
    Product Introduction
    The HWP05-20S Oxidizing Solids Tester is designed to evaluate the potential of solid substances to increase the burning rate or combustion intensity of a combustible material when thoroughly mixed with it. It determines combustion performance using either the combustion-time test method or the gravimetric method, supporting the assessment of oxidizing solid hazards and applicable dangerous-goods packaging classifications.
    The instrument supports both UN Manual of Tests and Criteria Test O.1 and Test O.3, as well as GB/T 21617-2008, Test Methods for Oxidizing Solids in Dangerous Goods. With automated optical detection, mass-loss measurement, environmental monitoring, and remote ignition, the HWP05-20S helps improve test consistency, data traceability, and operator safety.
     

    Performance Features
    1.  Embedded control system: Uses an embedded processor and Windows CE operating system for automated test management.
    2. 8-inch touchscreen: Displays real-time test status, operating time, and animated test progress.
    3. Dual-standard compatibility: Supports UN Test O.1 and Test O.3 procedures.
    4. Automatic combustion detection: An infrared sensor array detects combustion phenomena.
    5.  Automatic gravimetric measurement: A precision balance records mass loss during combustion.
    6. Metal-wire preparation mold: Includes a dedicated mold for preparing standard metal wires.
    7.  Wire-break detection and alarms: Automatically detects metal-wire fusing and provides audible and visual alarms.
    8. Environmental monitoring: Measures ambient temperature and relative humidity during testing.
    9. Remote ignition: Allows ignition to be controlled remotely to help reduce operator exposure during testing.
    10. Automated operation and reporting: Supports parameter configuration, automatic test execution, data storage, and report review.
     

    Working Principle
    The HWP05-20S evaluates the oxidizing behavior of a solid sample mixed thoroughly with a specified combustible reference material. The mixture is tested under the applicable standard procedure using a standardized inert metal-wire heating arrangement.
    • Combustion-time method (Test O.1): An infrared sensor array detects combustion-related events, allowing the instrument to monitor and record the test duration for evaluating combustion behavior.
    • Gravimetric method (Test O.3): An electronic balance measures mass changes during the test, enabling the recording of mass loss associated with combustion.
    The instrument displays test progress and timing, monitors ambient conditions, and stores test data for subsequent review and reporting. Test preparation, sample proportions, operating conditions, and classification criteria should follow the applicable standard.

    HWP05-20S vs. Conventional Oxidizing Solids Testing
    Comparison Item HWP05-20S Oxidizing Solids Tester Conventional Manual Testing
    Test methods Supports O.1 and O.3 Depends on available equipment and setup
    Combustion detection Automated infrared sensor array May require manual observation
    Mass-loss recording Automated balance measurement May require separate weighing and recording
    Test monitoring Real-time display of status and timing May involve manual timekeeping
    Environmental monitoring Integrated temperature and humidity measurement May require separate instruments
    Operator control Supports remote ignition Depends on the test arrangement
    Data management Electronic storage and report review May rely on manual records
    Alarm functions Automatic wire-fusing detection with audible and visual alarms Depends on the equipment configuration
    Note: This comparison describes general workflow differences. Actual performance depends on the test setup and the procedures required by the applicable standard.
     

    Frequently Asked Questions
