A, horizontal and vertical burning tester applies scope:

In the laboratory, method of test specimen placed on horizontal and vertical direction with a smallflame ignition and combustion performance after the

Two, horizontal and vertical burning tester national standards:

ISO 1210 plastics - horizontal and vertical sample and the small flame ignition source contact,

Test method for performance of horizontal and vertical burning method GB/T method 2408 plastic,

GB4609 vertical burning method

GB5455 textile fabrics - Determination of flame retardant performance of vertical method

The main technical indicators, and based on the understanding of absorbing domestic andimported combustion test instrument, combined with the development of China..

Characteristics of three, horizontal and vertical burning tester of the instrument:

Beautiful appearance, generous, stable transmission, compact structure, large adjusting range,applying the flame with automatic control, and no electronic ignition device, convenient operation. The results are reliable, provide the basis for the research of flame retardant materials, and various materials contrast to each other and grading.

Four, the definition of horizontal and vertical burning tester:

1, vertical burning method: Determination of combustion performance of contact materials in theignition source, including extinction time, scope and time of flame spread, and whether thecombustion behavior of this material by combustion method of other material due to material,comparison and fire resistance grading.

Combustion method, level 2: applicable to normal temperature, one end is fixed after the level of support, the other end hangs little plastic sample 10mm or other self supporting material quality control tests and flammability classification test. Is a powerful means to control material fire resistant quality and evaluation of products.

3, the textile fabric flame retardant performance determination of vertical method: specifies astandard test method for determination of flame retardant treated fabrics flame retardant properties of various, be used for the determination of the tendency of fabric preventcombustion and carbonization. For the determination of flame retardant requirements of clothingfabric, decorative fabric, flame retardant tent fabric occurred performance.

4, the flame

Under the stated experimental conditions, remove the ignition source, material continuouscombustion flame.

5, flaming time

Under the stated experimental conditions, remove the ignition source, material flame combustiontime.

6, flameless combustion

In the test specifications, remove the ignition source, when the flame combustion termination ornon flame generated material to keep the glow of combustion.

7, flameless combustion time

In the test specifications, when the flame combustion termination or remove the ignition source,material flameless combustion time.

Five, the principle of

Horizontal or vertical hold one end of the specimen, applying gas flame provisions on the sample free, burning velocity measured by linear (horizontal) or flame and flameless combustion time(vertical) combustion performance to evaluate the sample.

Six, technical indicators:

1, the sample size:

Sample size long (125 + 5) mm, wide (13 + 0.3) mm, thick (3 + 0.2) mm

Consultation by all parties concerned, also can use other thickness, but the maximum thickness should not exceed 13mm, and should be reported in the test report.

Note: thickness, density, anisotropic material, pigment, filler and the direction of flame retardanttype and content of different samples, the test results are not comparable.

2, the temperature of the environment (standards): (23 + 2) C

Relative humidity: (50 + 5)%

3, the power supply voltage and power: 220V + 10%, 50HZ, 100W;

4, the gas source:

Industrial grade methane gas or other fuel gases (liquefied petroleum gas, such as natural gas,coal and so on)

5, instrument appearance size of about:

Long 720mm wide 370mm high 850mm ““;

6, the timing device:

Accurate to 1s

7, thickness gauge or micrometer:

Accurate to 0.01 mm

8, the best use of medical absorbent cotton;

9, the Bunsen burner flame time on three shifts applied sample: 10s, 12s, 30s;

10, laboratory burner (Bunsen):

Cylinder length (100 + 10) mm; diameter of (9.5 + 0.3) mm;

11, the Bunsen burner tilt 45 degrees (adjustable).
