Introduction:
The design and production of protective gear flame spread testers follows ISO 15025. It is used to mimic protective clothing is at risk of igniting to assume the flame spread performance. It is also appropriate for the fabric material or other comparable functional usage of combustible materials. It can test the flame spread state under a tiny flame.
Standards:
EN BS ISO 15025
Procedure
1) Preparation of the test portion solution
a) Test portion Weigh (1士0,001) g of the test sample.
b)Test portion solution Transfer the test portion into a 250 ml beaker. Add 10 ml of hydrochloric acid and 10 ml of the nitric acid solution . Cover with a watch glass and heat gently until the test portion is completely dissolved, then heat at a temperature of approximately 90 °C until nitrous fumes have been expelled. Cool to room temperature. Wash the cover and the sides of the beaker with water. Transfer the solution to a 100 ml one-mark volumetric flask. Dilute to the mark with water and mix well.
Main Feature:
1. The combustion chamber is composed of beautiful, corrosion-resistant stainless steel; Size: 1200 mm by 600 mm by 1200 mm
2. All sample holders are manufactured from corrosion-resistant stainless steel;
3. Standard burner; nozzle opening 0.19 mm; vertical 40 mm 2 mm; flame height level 25 mm 2 mm;
4. Timer accuracy is 0.1s, and the time is automatically recorded and stored;
5. A PLC with a touch screen control system that enables more intelligent testing and automatically records test results and stores them;
6. With gauge and control valves from imported brands, the gas pressure is more steady;
7.Imports needle valve, which allows for fine adjustment of flame height and more stable flame;
8.High intellect, ease of use, and simplicity of operation;
9. Made of stainless steel with a bottom surface for combustion and combustion of two sample holders;
10. Automatically shuts off automatic ignition system;
11. containing a flame height indicator;
12. Electronic automated ignition with pulsed high voltage.
13.Time-consuming timing button with PLC automatically record storage combustion.
14.The system automatically records the test of time and generates test reports without requiring the user to hold a stopwatch or timer;
15. A touch screen and the test time and time can be set to fire. meet certain test requirements;
16. The touch screen's burner test programs for surface combustion and bottom surface combustion can be switched.
