SL-FL25 Heat Transfer Index Test Apparatus
Heat Transfer Index Test Apparatus for Evaluate the Thermal Protection Performance of Protective Clothing Fabrics
Product introduction of the Heat Transfer Index Test fitaovana
A new term heat transfer index (HTI) has been introduced to avoid confusion with the thermal protective index (TPI) or other terms used in previous versions of this test. HTI calculated from the mean time in seconds to achieve a temperature rise of 24±0.2℃ when testing by this method using a copper disc and a starting temperature of 25±5℃. The heat transfer index provides a method of grading materials which does not imply that the material tested will give any precise protective time under actual use conditions.
The convective heat resistance test device is developed according to EN367 and ISO9151 test standards, and meets the requirements of the convective heat resistance test standard of domestic AQ 6103-2007 welder protective gloves. The test results are thermal protection index (HTI). The principle of the test is to measure the test time required for the back temperature of the sample to rise 12 or 24 degrees by the impact of flame on the bottom of the sample. The average value of the three tests is recorded as thermal protection index (HTI), which is used to evaluate the thermal protection performance of the protective clothing fabric.

Product Feature of the Heat Transfer Index Test fitaovana
Mety maneho lelafo mari-pana, famarana mari-pana sy ny fotoana nomerika.
Ny fitaovana dia natao sy vokarina araka ny EN 367 sy fenitra ISO9151.
Ny fitaovana dia ahitana ny burner, ny rakotra fanaovam-panavotana sy ny taratasy specimen calorimeter mpihazona-barahina.
Ny taratasy sy ny rakotra fanaovam-panavotana specimen mpihazona dia manaiky hozakain'izy pneumatic alalan'ny fifindran'ny izay tonga dia fehezin'ny rindrambaiko.
A horizontally miompana specimen iharan'ny fitsapana ny zava-nitranga hafanana marary mitsika ny 80KW / ㎡from ny lelafo ny Meker burner ambany izany.
Ny hafanana mandeha mamaky ny specimen dia refesina amin'ny alalan'ny kely varahina calorimeter teo ambonin'ny sy ny fifandraisana amin'ny specimen.
Ny fotoana mba hanoratra ny fiakaran'ny hafanana amin'ny 12 na 24 ℃ ao amin'ny calorimeter dia voarakitra ao segondra.
Ny fitaovana hihena calorimeter manafohy ny fotoana fitsapana.
Ny fanahy result for ny telo fitsapana santionany dia kajy toy ny HTI.
Ny calibration ny hafanana mikoriana hakitroky ny 80 KW / ㎡is nanao ho azy ny softwa
Instrument toetra mampiavaka
Product application of the Heat Transfer Index Test fitaovana
Ny convective fitaovana fitsapana hafanana fanoherana ny fitaovana fiarovana dia fitaovana izay tena ampiasaina mba handrefesana ny convective hafanana fanoherana ny lamba, afo miady fitaovana sy ny fitaovana hafa.
