ASTM E1354 ISO 5660 BS 476 Cone Calorimeter Analyzer Cone Calorimetry Tester

Product Specification

ASTM E1354 ISO 5660 BS 476 Cone Calorimeter Analyzer Cone Calorimetry Tester 

1.Overview

The design principle of this equipment is based on the oxygen consumption calculated by the oxygen concentration in the gas stream of combustion products and the heat release rate of combustion products. The heat release rate of materials is also the most important parameter in the combustion performance of materials. The equipment can measure the heat release rate of materials in the combustion process more accurately, with beautiful appearance and convenient and accurate testing. Essential for predicting fire hazards and their flame retardant treatment, this device can be used to detect the mass loss rate, O2, CO, CO2 and heat release rate of all fire and flame retardant materials.

2. Meet the standard

Comply with GB/T16172-2007, ISO 5660-1:2002, ASTM E1354 and other current domestic and foreign test standards.BS 476 PT. 15:, NFPA 264.

3.Scope of application

Can be used for all fire and flame retardant materials to carry out smoke production, mass loss rate, O2, CO, CO2 and heat release rate, etc., to test flame retardant and combustion performance of materials under various preset conditions, and can also be used as correlation analysis data to import mathematical models to predict combustion behavior. Widely used in quality inspection units, scientific research institutions to analyze materials and test material heat release properties.

5.The composition of cone calorimeter

5.1 The cone calorimeter is composed of six parts: combustion chamber, load platform, oxygen analyzer, smoke measurement system, ventilation device and related auxiliary equipment.
5.2 Combustion chamber: the size is L1680mm×W700mm×H2410mm, which is composed of conical heater, igniter, control circuit and windshield.
5.3 Oxygen analyzer: It can accurately check the change of the percentage of oxygen in the ventilation pipe with time during combustion, and then determine the combustion and heat release of the material by the principle of immediate oxygen concentration and oxygen consumption.
5.4 Load stage: it can accurately record the quality change of the sample during the combustion process. During combustion, the sample is placed on the support of the load platform.

5.5 Smoke measurement system: The ventilation duct near the combustion chamber is equipped with a He-NE laser emitter and a double electron beam measuring device, so that the specific extinction area (SEA) of smoke in the smoke duct can be determined.

5.6 Ventilation system: Ventilation system refers to the device that exhausts combustion products from the combustion chamber to the atmosphere after the sample is burned.
5.7 Auxiliary equipment: The auxiliary equipment contains a microcomputer processor, a server, a heat flow meter device, and a corresponding device for removing CO2 and H2O(gas).
