EN50399 : 2001 ZY6260 Horizontal Flammability Tester Wire Cable Heat Release Tester
Scope of application:
It is applicable to the evaluation of flame spread, heat release and smoke characteristic test of a beam cable or optical cable installed vertically in a specific test condition.
Meet the standard:
Conformity to GB/t31248-2014, EN50399:2001, GA/t716-2007 "test methods for flame propagation and thermal release and smoking characteristics of cable and optical cable under fire conditions".
Main parameters:
The instrument is mainly composed of the combustion chamber, air supply system, standard ladder, ignition source, sensor and sensor pipe section, smoke density optical test system, gas analyzer software, data acquisition and processing system, computer control system, combustion gas control system and ventilation system and other parts.
Differential pressure transmitter: capacitance, accuracy, plus or minus 5 P a, range of 0 ~ 2 0 0 P a
Oxygen measurement: range 0-25%; Signal output: 4-20ma
Carbon dioxide measurements: range of measurement: 0-6%; Deviation: < 1
Exhaust fan: 2. 0 m3 / min
Light source: consisting of 6 V, 10W incandescent lamp, power supply transformer and variable resistor.
Optical window adder: AC220V power supply, 9W resistance wire is surrounded, to ensure the surface temperature of the light window (50 C ~ 55C) is appropriate.
Convex lens: 40mm in diameter and 50mm in focal length.
Photoelectric detector: it consists of photomultiplier tube, amplifying filter, optical brake, filter, neutral filter, convex lens, optical window, etc.
