一、概述

A, an overview of the

试验前详细阅读国家标准GB8626《建筑材料可燃性试验方法》，对您的试验工作将有很大帮助。

Test before read national standard GB8626 building materials flammability test method, test work will be of great help to you.

JCK-2型建材可燃性试验炉是判定在规定的条件下，建筑材料是否具有可燃性的试验方法，是根据国家标准GB8626规定的技术参数而研制的。

JCK - type 2 building materials flammability test furnace is determined under specified conditions, whether building materials have flammability test method, GB8626 is according to the national standard of technical parameters and developed.

三、式样尺寸：采用边缘点火90×190mm；采用表面点火90×230mm，每组试验需5个试件。

Three size, style: the edge of the ignition 90 x 190 mm; Using surface ignition 90 x 230 mm, each set of tests need five specimens.

四、试验步骤

4, test steps

1.检查仪器面板上的时间显示器设定值是否在标准值。

1. Check whether the time display setting of the instrument panel in the standard values.

2.接通电源、气源，把仪器面板上的“燃气开关”阀向右调到zui小，打开钢瓶阀门。

2. Turn on the power supply, air supply, "gas switch valve on the instrument panel to the right to transfer to the minimum, open the cylinder valve.

3.打开电源开关，按“复位”键使燃烧器复位。

3. Open the power switch, press the "reset" button to reset the burner.

4.打开燃烧箱门，将装有试件的试件夹固定在燃烧箱内，按“运行”键后，根据试件的情况调节试件夹与燃烧器的距离，再按“复位”键使燃烧器返回。

4. The door is open burning, will be equipped with a specimen of the specimen clamp fixed to the burn in, press "run", according to the specimen of regulating specimen clamp distance with burner, then press "reset" button to make the back burner.

5.向左“燃气开关”用点火器键点着燃烧器，调节火焰高度到20mm±2mmm，关闭箱门。

5. To the left with the ignition key on fire burner gas switch ", adjust the flame height to 20 mm + / - 2 MMM, the door is closed.

6.按“运行”键，使燃烧器对试件施加火焰15s，施加火焰完毕后，燃烧器自动移去，计量从点火开始至火焰到达刻度线或试件表面燃烧火焰熄灭的时间，按“计时”键仪器面板上的时间显示器停止，并记录此数据。

6. Press "run" button, make the burner on specimens flame for 15 s, after the flame, the burner automatically remove, measuring from ignition to reach the surface of the scale line or specimens flame burning flame of the time, press the "timer" key on the instrument panel display time stops, and record the data.

7.重复做5个试件后，关掉电源，“燃气开关”及钢瓶阀门，对燃烧箱、试件积进行必要的维护。

7. Repeat for five specimens after turn off the power supply, and the cylinder valve, gas switch "for combustion box, specimens for necessary maintenance.

8.“复位”：在试验过程中未到15s，火焰尖头已达刻度线，按“复位” 键移去燃烧器。

8. "reset" : in the process of test not to 15 s, flame pointed to calibration, press the "reset" key to move to the burner.

五、材料可燃性的判定

Five, judgement of flammable materials

经试验符合下列规定的建筑材料均的确定为可燃性建筑材料：

Tests comply with the following provisions of the building materials are indeed as combustible construction materials:

1.对下边缘未加保护的试件，在底边缘点火后开始后的20s内，五个试件火焰尖头均未到达刻度线。

1. The bottom edge of specimen without protection, at the bottom edge of the ignition after 20 seconds, after the beginning of the five specimens flame point did not reach the scale line.

2.对下边缘加以保护的试件，除符合（1.）规定外，应附加一组表面点火试验，点火开始后20s内，五个试件火焰尖头均未到达刻度线。

2. To the edge under protected specimen, in addition to the prescribed （1.）, should be attached a set of surface ignition test, ignition start after 20 seconds, five specimens flame point did not reach the scale line.
