1. the specimen holder consists of a frame made of two U-shaped corrosion-resistant metal plates.

2. The lower plate of the holder is equipped with six pins, and the upper plate is equipped with pin holes accordingly to ensure uniform clamping of the specimen. The pins also serve as markers for the starting point (one marker) and the ending point (two markers) of the burning distance.

another bracket with not only 6 pins on the lower plate, but also the bracket with a distance of 25 mm of heat-resistant metal support line, line diameter 0.25 mm (see Figure V), which is used in specific cases.

The bottom surface of the specimen after installation should be 178mm above the bottom plate of the combustion box. the distance between the front end of the specimen holder and the inner surface of the combustion box should be 22mm, and the distance between the two longitudinal outer sides of the test holder and the inner surface of the combustion box should be 50mm.

3. gas lamp is the test source of fire, gas lamp torch internal diameter of 9.5mm. when the gas lamp placed in the combustion box, the center of the torch mouth in the center of the free end of the sample 19mm below;.

4. supply gas lamp test with combustible gas combustion calorific value of about 38MJ/m2 (such as natural gas, city gas, liquefied gas).

5. metal comb with a length of at least 110mm and 7 to 8 smooth round teeth within every 25mm.

6. the accuracy of the stopwatch used to measure time is not less than 0.5s.

7. thermometer range should be more than 1500C, the accuracy of 10C.

8. steel plate ruler accuracy of 1mm.

9. Fume hood: combustion box should be placed in the fume hood, the internal volume of the fume hood for the combustion box volume 20 ~ 110 times, and the length, width, height of any size of the fume hood shall not exceed 2.5 times the size of any of the other two dimensions, before the test in the combustion box before and after the final determination of the position of each 100mm to measure the vertical velocity of air flow through the fume hood, the speed must be in 0.10 ~ 0.30m / s between.
