5KW Building Materials Surface Burning Characteristics Testing Equipment​​

 

Application:

This method is applicable to determine surface burning characteristics of building materials and

flame propagation rate of exposed surfaces such as walls and ceilings (including solid plastics),

at the same time measure smoke density.

This test method applies to the exposed surface which includes ceiling or walls, provided that the

materials or the whole assembly, with its own structural quality or the aspect in which is tested

and intended to use is able to support itself in position or being supported during the period of

test. The method is used to determine the corresponding burning behavior of the material by

observing the flame spread along the test specimen. Reports are made for the flame spread and

smoke density developed and it is not necessarily a relationship between the two

measurements.

⑥. Installation: install at one end of the pipe with length 150, the other end is a dustproof window,

inner wall of pipe is glossy black and anti-reflection.

⑦. Light transmittance 0% means no light passing, 100% means without shade, all pass

Features:

1. Measure flame propagation speed is based on the time of flame through the window to

estimate after lit sample, get flame propagation speed curve, which method is to draw the

distance and time flame propagation through window. The equipment should be calibrated firstly

when do test, and then do two preliminary tests. The first preliminary test is to detect red oak

specimen, artificially set its flame propagation and smoke generation as 100(this method also

measures material’s smoke generation). The second preliminary test is to detect asbestos

cement specimen, set its above two values as 0. Then determine specimen smoke and flame

propagation velocity curve, calculate flam spread index (FSI), the method is: if this total area is

less than or equal to 29.7m·min, that is FSI=0.515AT; if the total area is greater than 29.7m·min,

that is FSI=4900/(195-AT).

2. The flame propagation rate of various unprocessed wood is 60 to 230, the smoke generated is

also measured during combustion, and its rank is divided in the same range.

3. The FSI value of the material measured with tunnel method is between 0 and 200, the smaller

the FSI value is, the less the fire risk is. The high buildings and corridor, should use FSI<25

material, 25<FSI<100 material only could be used for fire requirement not very strict, while

FSI>100 material don’t meet the requirement of flame retardant.

4. Class A is 0-25, Class B is 26-75, Class C is 76-200, the sample that smoke index less than

450and flame spread rate curve, then calculate flame spread index(FSI) of the sample, the

method is: if this total area is less than or equal to 29.7m·min, that is FSI=0.515AT; if the total

area is greater than 29.7m·min, that is FSI=4900/(195-AT).

 

Procedure:

1. Six pcs samples, placed under 12mm thick calcium silicate cement.

2. Observe data:

A. Measure the time on flame arrived at each observation point

B. Measure the flame spread distance on the first 1.5 minute

C. Measure the flame spread distance during all the test (10 minutes)

D. Measure the flame spread max distance and time

3. Judgment method:

Classification

Flame spread at 1.5 min (mm)

Final flame spread (mm)

Class 1

165 (+25)

165 (+25)

Class 2

215 (+25)

455 (+25)

Class 3

265 (+25)

710 (+25)

Class 4

Exceeding Class 3 limits

 

 

BS Class 1 judge standard:

①. During six pcs samples, the sample that biggest “1.5 minutes flame spread value” and “last

flame spread value”, shall not exceed the max allowance (that is the sum of internal and external

value)

②. The “1.5 minutes flame spread value” and “last flame spread value” of another five pcs

samples should not exceed standard value (that is the external value)

Part 6: Fire propagation

①. Test method: measure temperature change (heating) by thermocouple sensor through

sealing space when burning sample.

②. Observe data: the temperature is measured every 30 seconds within 0-3 minutes ignition; the

temperature is measured every 1 minute within 4-10 minutes ignition; the temperature is

measured every 2 minute within 12-20 minutes ignition, and only measure 3 times.

③. Judgment method:

S1 = S2 = S3 =

S = S1 + S2+ S3

t----- time, in minutes, 0 when ignition

--sample temperature, in ℃, on time t

---standard temperature, in ℃, on time t

BS Class 0 judgment standard: Class 1 material total index S is not more than 12; the first

sub-index is not more than 6, which could be determined as Class 0.
