ISO 6942 Protective Clothing Heat Radiation Behaviour Test Apparatus

Introduction:
This Heat Radiation Behaviour Test Apparatus is designed according to ISO6942 and EN366 .

The test apparatus has a user-friendly, intuitive, Windows-based application that provides a complete thermal control, fault detectionanddata recording. RPP system configuration and burn prediction also included in theThermDAC.
User-defined test allows the operator to definea non-standardtest conditions and custom tolerances. You can view multiple graphs display with zoom feature to view specific conditions in details.

Real-time statistics can be applied to the test data within any user selected time range.
This Heat Radiation Behaviour Test Apparatus is used for performance evaluation against heat and flame protective clothing when faced with short flame thermal motion.Imposeda certain calorie density (80KW/m ² ± 5%) of heat, under the specimens that composed of protective clothing. When measuring the growth rate of heat through over time (time: seconds, temperature: ºC) by heat meter that installedon testsample, to determine the insulation properties of sample materials.

This Heat Radiation Behaviour Test Apparatus is also applied to measure the fabric of single-layer or multi-layer under high temperature thermal radiation properties, and fire-retardant insulation of plates.

Standards:

• EN 366:Protective clothing. Protection against heat and fire. Method of test: evaluation of materials and material assemblies when exposed to a source of radiant heat.
• ISO 6942:specifies two complementary methods (method A and method B) for determining the behaviour of materials for heat protective clothing subjected to heat radiation.
   

Main Features:
1, The Heat Radiation Behaviour Test Apparatus consists of radiationdevice, the specimen clamping device and control system;
2, Stainless steel frame structure, appearance, corrosion resistance, easy to clean;
3, Specimen size: 230mm x 80mm;
4, Radiation source is made up of 5 infrared quartz lamp, power 500W, and provide at least 80kW/m2radiant heat;
5, Standard copper heat flow meter,heatmeasuring range 0~100kw/m2;
6, A cooling device (cooling water inlet);
7, Intelligent water circulation control system;
8, The water temperature alarm function; ensure the safe operation and test stability;
9, Computer control system; to achieve more intelligent test and easy to operate;
10, Timer accuracy is 1s;
11, Constantan thermocouple: measurement Accuracy 0.1 ºC, meet the design requirements of ISO 6942
12, Metal protection shutters, with water cooling device;
13, Computer records and displays real-time continuous temperature curve;
14, Automatic operation mode, test time can be set freely.
15, According to ISO 6942-2002 (EN366) standards, there are two methods to test the thermal protection;
     The first method (A method) is a specimen to withstand a certain amount of heat radiation, recording changes in appearance in order to reproduce the material the inclementconditions .
     The second method (B method) is a calorimeter inside a specimen back, when heat conduction from samples back, recording temperature trends over time, in order to determine the level of thermal radiation transfer.
