一、概述

A, an overview of the

試驗前詳細(xì)閱讀國家標(biāo)準(zhǔn)GB8626《建筑材料可燃性試驗方法》，對您的試驗工作將有很大幫助。

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

JCK-2型建材可燃性試驗爐是判定在規(guī)定的條件下，建筑材料是否具有可燃性的試驗方法，是根據(jù)國家標(biāo)準(zhǔn)GB8626規(guī)定的技術(shù)參數(shù)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.

二、儀器的工作環(huán)境及主要技術(shù)指標(biāo)

Second, the instrument working environment and main technical index

1.環(huán)境溫度：15℃～25℃；

1. Ambient temperature: 15 ℃ to 25 ℃;

2.相對濕度：≤85％；

2. The relative humidity: 85% or less;

3.供電電壓和功率：220V 50HZ 100W；

3. The power supply voltage and power: 50 hz, 220 v, 100 w;

4.氣源：液化石油氣；

4. Source: liquefied petroleum gas （LPG）;

5.本生燈對式樣施加火焰時間15s；

5. The Bunsen burner on style fire time of 15 s;

三、式樣尺寸：采用邊緣點(diǎn)火90×190mm；采用表面點(diǎn)火90×230mm，每組試驗需5個試件。

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、試驗步驟

4, test steps

1.檢查儀器面板上的時間顯示器設(shè)定值是否在標(biāo)準(zhǔn)值。

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

2.接通電源、氣源，把儀器面板上的“燃?xì)忾_關(guān)”閥向右調(diào)到zui小，打開鋼瓶閥門。

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.打開電源開關(guān)，按“復(fù)位”鍵使燃燒器復(fù)位。

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

4.打開燃燒箱門，將裝有試件的試件夾固定在燃燒箱內(nèi)，按“運(yùn)行”鍵后，根據(jù)試件的情況調(diào)節(jié)試件夾與燃燒器的距離，再按“復(fù)位”鍵使燃燒器返回。

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?xì)忾_關(guān)”用點(diǎn)火器鍵點(diǎn)著燃燒器，調(diào)節(jié)火焰高度到20mm±2mmm，關(guān)閉箱門。

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“運(yùn)行”鍵，使燃燒器對試件施加火焰15s，施加火焰完畢后，燃燒器自動移去，計量從點(diǎn)火開始至火焰到達(dá)刻度線或試件表面燃燒火焰熄滅的時間，按“計時”鍵儀器面板上的時間顯示器停止，并記錄此數(shù)據(jù)。

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.重復(fù)做5個試件后，關(guān)掉電源，“燃?xì)忾_關(guān)”及鋼瓶閥門，對燃燒箱、試件積進(jìn)行必要的維護(hù)。

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.“復(fù)位”：在試驗過程中未到15s，火焰尖頭已達(dá)刻度線，按“復(fù)位” 鍵移去燃燒器。

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

經(jīng)試驗符合下列規(guī)定的建筑材料均的確定為可燃性建筑材料：

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

1.對下邊緣未加保護(hù)的試件，在底邊緣點(diǎn)火后開始后的20s內(nèi)，五個試件火焰尖頭均未到達(dá)刻度線。

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.對下邊緣加以保護(hù)的試件，除符合（1.）規(guī)定外，應(yīng)附加一組表面點(diǎn)火試驗，點(diǎn)火開始后20s內(nèi)，五個試件火焰尖頭均未到達(dá)刻度線。

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.
