Non-combustible test furnace

Overview

The non-combustible test furnace for building materials is designed and manufactured according to the specifications of GB/T5464-2010/ISO1182:2002. A non-combustibility test method for determining the main composition of a homogeneous building product under specific conditions.

It is applied to the test method for non-combustibility of building materials and is suitable for testing building materials. For composite articles, the components of the components that make up the article can be tested separately and described in the test report. Coated, finished or multi-layered articles can also be evaluated for other fire reaction test methods. The test instrument can also be used to test BS 476-4 & 11 and IMO FTP part 1 standards.

experiment method

1,

The furnace temperature is balanced. If the temperature recorder cannot perform real-time calculations, the temperature should be checked for balance.

2,

Before the test, ensure that the whole device is in good working condition. For example, the air stabilizer is clean and unobstructed, the insertion device can slide smoothly, and the sample holder can be accurately located in the specified position in the furnace.

3,

A sample prepared according to the regulations and adjusted by the state is placed in the sample holder, and the sample holder is hung on the support member. Insert the sample holder into the specified position in the furnace. The operation time should not exceed 5 s. The timer is started immediately when the sample is in the specified position in the furnace. Record the temperature measured by the thermocouple in the furnace during the test. If the surface temperature and center temperature of the sample are required to be measured, the corresponding temperature should also be recorded.

4,

Perform a 30-min test, if the temperature in the furnace reaches the final temperature equilibrium at 30 min, that is, the temperature measured by the thermocouple drifts within 10 min (linear regression) does not exceed 2

°C, you can stop the test. in case

If the temperature balance is not reached within 30 minutes, the test should be continued, and the final temperature balance should be checked every 5 minutes. When the temperature in the furnace reaches the final temperature balance or the test time reaches 60 minutes, the test should be terminated. The duration of the test was recorded and the sample holder was removed from the furnace. The end time of the test was the end of the last 5 min or 60 min. If the temperature recorder cannot be recorded in real time, the temperature record at the end of the test should be checked after the test. If the above requirements are not met, they should be retested. If additional thermocouples are used in the test, the test shall be terminated when all thermocouples reach the final temperature equilibrium or when the test time is 60 min.

5,

Collect all carbides, ash and other debris that have been broken or dropped during the test and after the test. After being placed in a drying vessel with the sample and cooled to ambient temperature, the residual mass of the sample is weighed. The mass of each set of samples was recorded before and after the test and the burning behavior of the test pieces during the test was observed. Record the duration of the flame and the duration of the occurrence, accurate to the second. A continuous flame on the surface that is visible for 5 s or longer on the surface should be considered a continuous flame.

6,

Record the measured temperature of the thermocouple in the following furnace, in degrees Celsius, the initial temperature in the furnace T1, the average temperature of the last 10 minutes of the specified furnace temperature equilibrium period; the maximum temperature in the furnace Tm, the discrete value of the maximum temperature during the whole test period; The final temperature Tf in the furnace. The average temperature of the last 1 min of the test.

At the end of the test, the test furnace is wiped clean for the next use.
