Heat resistance and wet resistance tester

[Application Standard]: GB / T11048-2008, GB / T11048-2019, ISO11092, ASTM F1868 (A-E), etc.

[Main functions]: Suitable for thermal resistance and wet resistance testing of plane materials such as medical products, textiles, clothing, bedding, sleeping bags, interior decorations, thin film, coating materials, foam, leather, multilayer fabric combination of textiles.

[technical function]:

1. Including test methods: (1) A method evaporation heat plate method; (2) B method static plate method; (3) heat absorption and heat release test of phase change fabric;

2. Size of central test board: 200mmX long, 200mm long, and about 3mm thick. The test board is made of microporous plate made of special stainless steel powder metallurgy, with high simulated skin sweating effect.In a 20℃ environment, a beam in a wavelength range of 8um to 14um is illuminated vertically on the surface of the test plate and reflected in the hemisphere, and the radiation coefficient of the test plate surface is higher than 0.4;

3. Tstable sample size: greater than 350mm 350mm;

4. With the one-key preheating function, which greatly shortens the test time and improves the test efficiency.

5. Test sample thickness range: 0~70mm (high-precision motor drive lifting system, quickly cooperate with the test of different thickness samples)

6. Temperature adjustment range of the test board: 20~50℃, temperature control accuracy: ± 0.1℃, resolution: 0.01℃;

7. Thermal resistance (Rct):

(1) Test range: 0 ~2.000m2 K / W;

(2) Resolution: 0.00001m2 K /;

(3) Repeatability error is ± 2.5%;

8. Wet resistance (Ret):

(1) Test range: 0~1000 m2 Pa / W;

(2) Resolution: 0.01m2 Pa / W;

(3) Repeatability error is ± 2.5%;

9. Air flow and wind speed: 0.5, 1.0, 1.5m/s optional, ± 0.05 m/s adjustment;

10. Climate room requirements:

10.1 20℃± 0.1℃ resolution: 0.01℃, 65% ± 2% resolution: 0.01% (thermal resistance);

10.2 35℃± 0.1℃ resolution: 0.01℃, 40% ± 2% resolution: 0.01% (wet resistance);

11. High-precision water level automatic supply system, with an error of less than 1mm;

12. The performance of the sample can be directly measured and calculated.(Thermal resistance, wet resistance, moisture permeability, moisture permeability index, heat preservation rate, heat transfer coefficient, Croo value) without manual calculation;

13. External size: 10007701800mm;

14. Weight: 400Kg;

15. Power supply: AC220V± 10%, 4000W.

16. Provide 100 GB / T11048 and ASTM F1868 films; two sets of imported samples (8, heat and wet resistance: 4,2) and one set of Marine cotton samples (3).
