Applicable scope:
The combustion heat value tester for building materials is mainly suitable for testing the combustion heat value of building materials in a constant heat capacity oxygen bomb calorimeter. Including total combustion heat value and net heat value.
The role of EN ISO 1716:2018 test in the European Classification System
EN ISO 1716:2018 Reaction to fire tests for products - Determination of the gross heat of combustion (calorific value) Reaction to fire test of building materials. Determination of calorific value (calorific value).
EN ISO 1716:2018 can test A1 and A2 grade as well as A1fl and A2fl grade floors, which require the determination of the heat of combustion of the material (the main and non-main components of the product).
Testing principle
In this test, under standard conditions, in an oxygen environment, at a constant volume, and in a high-pressure heat bomb, the specified mass of the sample is completely burned. The calorific values determined under these conditions are calculated based on the observed temperature rise, taking into account both heat loss and the latent heat of vaporization of water. This test can determine the absolute burning value of the product.
Testing equipment
This device is usually called an oxygen bomb. This device consists of three main parts, namely the projectile body, the warhead and the projectile body sealing cover. The warhead contains a crucible support and electrodes for initiating the reaction. The volume of an atomic bomb is ±300 milliliters. Immerse the atomic bomb in the water of the calorimeter container, and then place both in the heat-insulating water jacket.
Testing process
Before conducting the test, calibrate the bomb calorimeter with the water equivalent of a standard organic compound (benzoic acid) measuring instrument of known calorific value. Mix the powder or chopped sample of the specified mass with an equal amount of the combustion aid (benzoic acid) and directly place it in the crucible in granular form. If complete combustion cannot be achieved by the crucible method, the sample can be wrapped in a crucible to ensure complete combustion.
