Flame Spread Rate Tester, NF P92-504

Flame Spread Rate Tester, NF P92-504

Introduction:

The test is designed to subject a sample made of a certain material to a heat source constituted by a gas igniter under certain conditions, and may cause: a sample fire and a test of the flame duration and the spread and spread of the flame The speed test is in line with the fire reaction performance test of French building materials and high-speed rail non-metallic materials.

 Model: GD-NFP92-504

  Reference Standard:

   ▪ NF P92-504

  Main Features:

  Features of the box and fixture:

  1. Applicable to French building materials and high-speed rail test standards, in line with the test standard NFP 92-504.

  2. The sample fixture is made of 304 stainless steel, which is beautiful and corrosion-resistant.

  3. Equipped with U-shaped sample holders for soft and hard materials.

  4.  Advanced industrial appearance design, ergonomic design in consideration of test operation, easy to install samples,        burner moving track design, easy to operate.

  5. The burner is designed to be controlled by a rotary motor to realize automatic control of positioning, ignition and return.

  6. 304 stainless steel flame height scale, flame height 20mm, precision 0.5mm.

  7. The tester is composed of a test part and a control part, and adopts an integrated design, which is convenient for on-site    installation and debugging.

  Blowtorch and gas control:

  1. The burner angle can be automatically adjusted at 0 and 45 degrees;

  2. The base of the Bunsen burner (Humboldt) imported from the United States is equipped with a standard burner, and the    sample is subjected to flame impact, and the flame spread performance of the sample is observed;

  3. The flow rate of the blowtorch itself can be adjusted;

  4. Imported flowmeter and precision needle valve to precisely control the flow of combustion gas;

  5. Imported brand high-precision pressure regulating valve and pressure gauge 0~0.4Mpa;

  6. Accurately control the flame height to 20mm;

  Microcomputer control system

  1. Programmable controller 7" touch screen to realize control/detection/calculation/data display.

  2. Pulse high-voltage electronic automatic ignition.

  3. Timing button cooperates with PLC to automatically record and store the burning time.

  4. The time timer detects the time when the flame reaches the 50 and 300mm marking lines. Accuracy 0.1s, automatic          timing;

  5. There is no need to hold a stopwatch or manuscript for timing; the test time system automatically records and generates    an experiment report;

  6. The test time and heating time can be set on the touch screen. Meet the requirements of various test standards;

  7. Linear combustion rate (V) is automatically calculated by PLC, displayed and saved on the touch screen.

  8. The automatic timer device can record the test time and store it in the system, and the report can be queried;
