ZY6235B-PCE Flammability Test Chamber Piradiateur Radiation Flame Propagation

ZY6235B-PCE Flammability Test Chamber Piradiateur Radiation Flame Propagation

Scope of application:

Applicable to any single or synthetic hard material of any thickness, all bonded decorative materials with a thickness of more than 5MM of soft material. It also applies to any thickness of the wall or the flaking board (i.e., flat roof, inner top), soft filter material.

Meet the standard:

Compliance with TB/T 2639.1-1995 "experimental radiation test method for the fire resistance of railway vehicles" and French standard NF p92-501:1995 test standard.

Main parameters:

1. Test box: 760MM (long) *463MM (wide) *1010MM (high) is made of stainless steel plate and is made of high temperature electrostatic baking paint.

2. Radiator: Epiradiator thermal radiation device, rated power is 500 w, radiating surface is a diameter of 100 + / - 5 mm quartz disk, intraday spiral CaoRao resistance wire, used to heat the spiral groove six laps, from 30 mm parallel plane, through the radiator heat flux density of 3 w/CM2, and uniform as possible.

3. Sample support: made a high-end three root Angle for open rectangle frame, a u-shaped, supporting bracket on both sides of the Angle welding with fixed tags, is used to measure the length of the flame, sometimes test need sample retainer, so the supporting frame is welded on both sides, there are two fixed retainer clip.

4. Temperature measurement device:

A. in the center of the test chamber exhaust port and four diagonal arrangement on five thermocouple, the other at the air inlet at the bottom level 5 thermocouple, measure the airflow temperature at the input and output side, real-time display temperature difference value.

B. Thermocouple: the use of nickel chromium -- the thermocouple of nickel aluminum magnesium alloy and 0.5mm diameter of resistance wire.

C. Temperature record: computer temperature module and I/O block input computer display, temperature acquisition time of 10 seconds.

D.2.5MM stainless steel plate, weight unit (unit decigram)

E. The calorimeter measurement of the copper plate adjusts the heat flux density of the radiator.

5. Control system and operation interface:

A. Labeview with instruments and equipment dedicated development software and control data acquisition card, the control test in the process of thermal radiation can be real-time display unit operating power value, from frequent calibration procedures, to view the test data curve, which can realize the automatic data acquisition and processing. Data saving and output measurement results, data can output and print, friendly operation interface mode

B. Control mode: using board card, module I/O card, PID+SSR control mode. The collection system can collect record samples and the raw flame time T1 and T2 above, and record the temperature difference between air input and outlet of the test box in real time. Flame index, flame average height index S, maximum flame index H, burning heat index C, etc.

C. Lenovo computer one: model: m4360-b013; CPU cores: 2 cores; Total capacity of hard disk: 250GB; Total memory capacity: 2GB; CPU frequency: 3GHZ; Graphics chip: high-performance integrated graphics card.

D. Work power: AC220V, 50HZ

E. ambient temperature: normal temperature.
