Scope of Application

【Operating Instructions】

With the revision of the GB 8965.1-2020 standard, the flame retardant performance under finished product flashover conditions has become a mandatory requirement. The Manikin Flashover Test System, developed in accordance with ASTM F1930, ISO 13506, GB/T 23467, and other standards, is mainly composed of a gas supply system, a combustion system (6 sets / 12 burners), a manikin system, a testing system, and a safety protection system. It simulates complex fire scenarios to evaluate the thermal protective performance of garments, enabling an effective assessment of the overall thermal protection level of clothing. Through this testing service, the Manikin Flashover Test System has been validated.This system features high technological content and product added value. It not only demonstrates the enterprise’s R&D capabilities and overall strength in the safety protection sector but also serves as a new economic growth point for the machinery and electronics segment, supporting high-quality development. This is the Manikin Flashover Test System.

This is the Manikin Flashover Test System.

**【Scope of Application】**  

The Manikin Flashover Test System simulates the heat exposure process of a clothed human body (manikin) when subjected to flames. It measures temperature changes on the manikin’s surface to predict potential second-degree and third-degree skin burns and the total percentage of burned body area, providing precise estimates of burn severity. Conducted in a high-simulation flashover environment chamber that replicates high-risk fire scenarios, the system enables the evaluation of flame retardant performance and research into influencing factors for various protective equipment, such as firefighter suits and military uniforms.

**【Applicable Standards】**  

ASTM F1930-2000, ISO 13506-2008, GB/T 23467-2009, GB 8965-2020

**【Technical Parameters】**  

**1. Combustion Chamber System**  

- The combustion chamber adopts an integrated fire-resistant structure, constructed from a metal frame and flame-retardant materials.  

- Effective internal dimensions: 4.0 m (L) × 4.0 m (W) × 3.0 m (H) (minimum required building height: 4 m, floor area: at least 50 m²).  

- **Ventilation and Exhaust System**  

  The test chamber is equipped with pre‑designed fans that automatically adjust airflow for ventilation and exhaust according to different test phases, ensuring adequate ventilation and oxygen supply during testing. After each test, it quickly exhausts combustion gases and introduces cooling air.

**2. Flashover Generation and Safety Control System**  

- **Burners:** 6 sets / 12 burners  

- **Gas Supply System:**  

  Includes propane gas pipelines, pressure regulators, valves, and pressure sensors for delivering gaseous propane to the ignition system and burner nozzles. The system provides uniform, consistent heat flux (at least 84 kW/m²) with a fuel delivery timing accuracy of ±0.1 s.  

- **Safety Systems:**  

  Gas detectors, door seal detectors, flame detectors, fire extinguishers, emergency stop devices, and other necessary safety equipment.

**3. Thermal Manikin System**  

- The manikin is designed to resemble a 1.8 m adult male in form and dimensions, with components including head, chest, back, abdomen, arms, hands, legs, and feet. The shell is made of fully flame-resistant, thermally stable non‑metallic materials (customizable).  

- Joints are adjustable, allowing various postures to meet specific garment testing requirements (Model DR666-40RC only).  

- **Heat Flux Sensors:**  

  Mounted on the manikin’s surface to accurately measure temperature changes.  

  - Model DR666-40R: 130 sensors  

  - Model DR666-40RC: 146 sensors (including independent head and hand test zones)

**4. 3D Measurement System (Model DR666-40RC only)**  

  Utilizes 3D digital measurement technology for garments to evaluate shrinkage before and after combustion.

**5. Centralized Computer Control System and Application Software Platform**  

  A proprietary software system enables full computer control of the entire test process, with data acquisition and analysis completed automatically.
