Room Corner Tester, Medium scale calorimeter : Avg., max 3㎿, RCT-607, Furniture Calorimeter, ISO 9705, ISO 13754, ASTM E 1537, KS F ISO 13784

Introduction

Room Corner Tester (RCT), as ISO's the evaluation of fire-resistance performance of building materials, measures heat release rate (H.R.R), smoke generation rage, oxygen consumption, CO, CO2 production and so on.
As basis of ISO 9705(Fire tests . Full scale room test for surface products), RCT is the test that reproduces local fire conditions by flame combustion in the small room of building structure and measures fire movement and combustion diffusion in the building structure. ISO 9705 states a test method to progress fire generation from the corner of room and the purpose of this test method is to assess what the surface product supplies to the fire growth using standard ignition source.
The standard ignition source is stated but another option is also possible. But we must be careful of what the form, position and heat output influence to the fire growth. This method is suitable to the product - materials like thermoplastic resin, insulated circuit, joints and laboratory having irregular surface - which is impossible to experiment in the small laboratory. The object of this method does not assess fire resistance of product. So FESTEC's Room Corner Tester (RCT) on ISO 9705 assesses the Heat Release Rate about initial step of fire from ignition to maximum flash-over. The maximum Heat Release Rate can be measured up to 3MW.
