ISO 5660-1, ASTM E1354, ISO9705 How to conduct physical room fire test

In recent years, fire accidents involving confined spaces such as hotel rooms, student dormitories, shopping malls, private rooms for singing and dancing and entertainment have occurred frequently, causing serious casualties and major property losses. For this reason, the fire protection code for building design is constantly revised. For the fire safety of confined spaces, the experimental research is carried out based on ISO9705 room fire, and the test data of Cone Calorimeter is used as the basic input parameters. The same fire scene has been tested on fire source propagation and smoke spread characteristics, so how to test ISO9705 room burning?

Use Cone Calorimeter to test pine wood, MDF, PVC carpet and indoor furniture, and use FDS burning decomposition model to simulate and calculate the burning of the same material under the same working conditions, and compare the results of the two analyze. The test is divided into two parts: ISO 5660-1 and ASTM E1354 Cone Calorimeter test, and ISO9705 test. The ISO 5660-1 and ASTM E1354 cone calorimeter test is to place a single furniture sample component material in a cone calorimeter to test its heat release rate curve per unit area and other parameters. The ISO9705 test is to place multiple pieces of furniture in the ISO9705 burning room and ignite them in a certain way to obtain the characteristic parameters such as the total heat release rate.

Cone Calorimeter Test

The cone calorimeter test is shown in Figure 1.

ISO9705 burning test

The ISO9705 corner fire test device is a commonly used test device for studying the flame spread characteristics of wall decoration materials. The indoor headroom dimensions of the test room are 3.6m×2.4m×2.4m in length x width x height. The door of the test room is set at the center of the short side wall on one side, with a width x height of 0.8m x 2.0m, and the other walls, floors and roofs have no vents. The interior of the test room is composed of non-combustible materials with a density of 500~800kg/m³ and a thickness of not less than 20mm.

The ISO9705 corner fire test device is equipped with a conical fume collecting hood directly above the entrance, and the fume collecting hood is connected with the smoke exhaust pipe.
