Fabric thermal protection performance tester

Fabric thermal protection performance tester

Applicable scope:

Used to measure the thermal radiation resistance of single or multiple layers of fabrics in high temperature environments, and can also be used to measure the thermal insulation performance of other fire-resistant and flame-retardant panels. The thermal radiation resistance is an important performance indicator of flame retardant products. Accurately measuring its protective performance has important guiding significance for selecting materials, researching and developing new products, and improving processing technology.

Compliant with standards:

EN 366, ISO 6942-2002

Technical indicators:

1. Heating power of silicon carbide rod: 6.5kW/220V/50Hz, heating section length 178mm, diameter 8mm;

2. Heat flux density of heat source: adjustable from 10kW/m2 to 80kW/m2;

3. Temperature control of thermal radiation source: room temperature~1200 ℃± 5 ℃ (display accuracy of 1 ℃);

4. Thermal radiation source temperature sensor: thermocouple (0-1600 ℃);

5. Thermal radiation source temperature controller: equipped with PID intelligent adjustment controller;

6. Calorimeter heat capacity: measured to be approximately 480.937 J/K, with a heating area of 50 × 50mm2;

7. Temperature measurement range of calorimeter: room temperature~80 ℃; Temperature sensor Pt100 platinum resistance (-200~450 ℃);

8. Running platform: Chinese Windows XP operating system, data output: t1, t2, t3, qc, TF and their average values;

11. Circulating water pump: HQB-3900/100W/220V/50Hz;

12. Air source: Mini air compressor, power 1/4HP 220V/50Hz;

13. Test environment: Between 15 ℃ and 35 ℃, there should be no air circulation indoors;

Testing method:

According to the ISO 6942-2002 (EN366) standard, the protective properties of materials can be tested using two testing methods. The first method (Method A) involves subjecting the specimen to a certain amount of thermal radiation, in order to reproduce the harsh conditions the material is subjected to, and to record the appearance changes. The second method (Method B) is to place the calorimeter on the back of the sample, transfer heat from the back of the sample, and record the trend of temperature over time to determine the level of heat radiation transfer.
