編號：GD201311030063

規(guī)格：JZKR-A

建筑材料可燃性試驗儀

產(chǎn)品名稱：建筑材料可燃性試驗儀

產(chǎn)品型號：JZKR-A

主要用途：

適用于在規(guī)定的條件下判定建筑材料是否具有可燃性。

建筑材料可燃性試驗儀技術(shù)指標(biāo)：

1、噴嘴孔徑：￠0.17+0.03mm

2、火焰高度：20±1mm

3、點(diǎn)火器計時：0～99.99秒任意設(shè)置

4、使用氣體：純度在95%以上的丙烷氣

5、試樣尺寸：250mm×90mm

6、點(diǎn)火定位裝置

7、融化滴落制品的試樣夾

建筑材料可燃性試驗儀適用標(biāo)準(zhǔn)：

GB/T 8626-2007 《建筑材料可燃性試驗方法》

ISO 11925-2：2002

建筑材料可燃性試驗儀操作方法

1、使用250mm×90mm的模板切割試樣。如果試樣為融化收縮制品，則選用250mm×180mm的模板。

2、將試樣夾在尺寸為250mm×90mm試樣夾內(nèi)，擰緊蝶母，固定好試樣。融化收縮制品樣夾尺寸為250mm×180mm。此時試樣夾先不要裝到水平桿上。

3、打開電源開關(guān)，將點(diǎn)火時間設(shè)的稍長一些，比如5min。根據(jù)點(diǎn)火方式選擇相應(yīng)的定位器，按試驗開始，燃燒器在45°位置停止后，將定位器的一端插入燃燒器中。此時將試樣夾裝到水平桿上，調(diào)節(jié)試樣夾的上下左右位置，使其符合試驗要求。將定位器取出。按返回鍵。等燃燒器復(fù)位后，按試驗清零。

4、長按點(diǎn)火鍵，同時調(diào)節(jié)儀器面板上的火焰調(diào)節(jié)閥，點(diǎn)著氣體后，再調(diào)節(jié)火焰高度到20士1mm，將火焰從大調(diào)到小時，先將面板上的火焰調(diào)節(jié)旋鈕背緊，再調(diào)節(jié)火焰會比較容易。測高尺高度20mm。關(guān)閉前門。

5、將收集盤內(nèi)放兩張濾紙，然后將其放在試樣下方。

6、設(shè)定點(diǎn)火時間，按試驗開始，燃燒器自動轉(zhuǎn)到45°位置，并在該位置停留設(shè)定的點(diǎn)火時間，然后復(fù)位，同時續(xù)燃時間開始計時。在試樣續(xù)燃未達(dá)到刻度線前停止續(xù)燃后，按下續(xù)燃停止或試樣續(xù)燃達(dá)到刻度線后立即按下續(xù)燃停止。記錄燃燒時間。

7、按試驗清零，停止試驗。如想繼續(xù)進(jìn)行試驗可重復(fù)以上步驟，否則關(guān)閉電源。

ISO 11925-2:2002

=========================================

The operation method of building materials flammability test instrument

Sample 1, using the 250mm * 90mm template cutting. If the sample is melted contraction product, choose 250mm x 180mm template.

2, the sample size of 250mm * 90mm in the specimen holder, tighten the butterfly nut, fixed specimens. Melting shrinkage products like clip size is 250mm × 180mm. The sample holder should not be attached to the horizontal bar.

3, turn on the power switch, the ignition time is slightly longer, such as 5min. According to the ignition mode select positioner, according to the test, the burner at 45 ° position after the stop, the locator is inserted into the burner. The sample is clamped to the horizontal rod, adjustable sample holder on the left and right position, to meet the testing requirements. The locator out. Press the return key. Burner after reset, reset according to the test.

4, long press the ignition key, while adjusting the instrument panel on the flame regulating valve, a gas, then adjust the flame height to 20 ± 1mm, the flame from major to hours, the best first panel on the flame adjusting knob back tightly, then adjust the flame will be easier. Altimeter scale height 20mm. Close the front door.

5, will collect the tray placed two pieces of filter paper, and then put it in the sample.

6, set the ignition time, according to the test, automatic burner to the position of 45 DEG, and stays at the position the ignition time, the set and reset, and continued ignition timing starts. In the sample continued burning did not reach the scale line before the end of the continued burning, press the continued burning stop or sample continued burning reach scale line immediay after the press continued burning stop. To record the burning time.

7, according to tests cleared, stop test. If you want to continue testing can repeat the above steps, or turn off the power.
