Sample Details

 The details of the tested specimen given below have been prepared from information provided by the sponsor of the test. All values quoted are nominal, unless tolerances are given.

Test result:

1. ASTM E84:2009c

• Test Conducted

This test was conducted in accordance with ASTM E84:2009c Standard Test Method for Surface Burning Characteristics of Building Materials.

• Introduction

The method, designated as ASTM E 84:09c, “Standard Method of Test for Surface Burning Characteristics of Building Materials”, is designed to determine the relative surface burning characteristics of materials under specific test conditions. Results are expressed in terms of flame spread index (FSI) and smoke developed index (SDI).

The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported. However, there is not necessarily a relationship between these two measurements.

• Test Procedure

The tunnel is preheated to 150°F, as measured by the floor-embedded thermocouple located 23.25 feet downstream of the burner ports, and allowed to cool to 105°F, as measured by the floor-embedded thermocouple located 13 feet from the burners. At this time the tunnel lid is raised and the test sample is placed along the ledges of the tunnel so as to form a continuous ceiling 24 feet long, 12 inches above the floor. The lid is then lowered into place.

Upon ignition of the gas burners, the flame spread distance is observed and recorded every 15 seconds. Flame spread distance versus time is plotted ignoring any flame front recessions. If the area under the curve (A) is less than or equal to 97.5 min·ft, FSI = 0.515·A; if greater, FSI = 4900/(195-A). Smoke developed is determined by comparing the area under the obscuration curve for the test sample to that of inorganic reinforced cement board and red oak, arbitrarily established as 0 and 100, respectively.

• Conditioning

Prior to testing, the sample was conditioned,

To a constant weight at a temperature of 73.4±5°F (23±2.8°C) and at a relative humidity of 50±5%

Exposed Face:

One face of the specimen was exposed to the flame.

 Mounting Methods:

The specimen was self-supporting and was placed directly on the inner ledges of the tunnel.

The specimen consisted of 3 pieces of 2470mm×600mm×12mm scetions jointed end-to-end.

Rating:

The National Fire Protection Association Life Safety Code 101, Chapter 10, Section 10.2.3 “Interior Wall and Ceiling Finish Classification”, has a means of classifying materials with respect to Flame Spread and Smoke Developed when tested in accordance with NFPA 255, ASTM E84, UL 723 “Method of  Test of  Surface  Burning Characteristics of Building Materials”.

International Building Code, Chapter 8, Interior Finishes, Section 803 “Wall and Ceiling Finishes”,  was       classified in accordance with ASTM E84 or UL 723. Such interior finish materials shall be grouped in the following classes in accordance with their flame spread and smoke-developed indexes.

Since the tested sample received a Flame Spread Index 5 and a Smoke Developed 100, it would meet the requirement of Class A interior Wall & Ceiling Finish Category.

OBSERVATIONS

 NOTE: The use of supporting materials on the underside of the test specimen has the ability to lower the flame spread index from those which might be obtained if the specimen could be tested without such support. These test results do not necessarily relate to indices obtained by testing materials without such support.

Testing of materials that melt, drip, or delaminate to such a degree that the continuity of the flame front is destroyed, results in low flame spread indices that do not relate directly to indices obtained by testing materials that remain in place.

• Test conducted

This test was conducted in accordance with the procedure specified in BS 476 Part 6:1989 + A1:2009

—Fire tests on building materials and structures －Part 6: Method  of  test for fire propagation  for  products.

• Test details Conditioning:

Prior to testing, the sample was conditioned,

to constant mass at a temperature of 23 ± 2 °C, and a relative humidity of 50 ± 10 %, and maintained in this condition until required for testing.

Exposed Face:

One face of the specimen was exposed to the flame. Form in which the specimens were tested:Material

• Test results

Throughout the test on each specimen, carefully observe the material’s behaviour within the apparatus and take special note of any of the following phenomena listed in clause 9.2 of the standard. None of the listed phenomena was observed and the test results on all three specimens tested were valid.

The index of the performance for the specimen was determined as follows:

S = index of performance for each of the specimens tested and S1, S2 and S3 are sub- indices t = Time in minutes from the origin at which readings are taken

qs = Temperature rise in ℃ for the specimen at time, t

qc = Temperature rise in ℃ for the calibration sheet at time, t

Fire Propagation index

I = i1  + i2  + i3

Where,  i1 , i2

and i3   are given by the expressions:

i1  = 13 [(S1 )A  + (S1 )B  + (S1 )C ],  i2  = 13 [(S2 )A  + (S2 )B  + (S2 )C ],  i3  = 13 [(S3 )A  + (S3 )B  + (S3 )C ]

The following test results were obtained for each specimen tested:

Sub – indices                         Index of performance

Number of Specimens tested

Sub-index i₁

Sub-index i₂

Sub-index i₃

Fire Propagation index I

3                      0.70              0.69              0.54                        1.92

Note: If a suffix “R” is included in the above fire propagation index I, this indicates that the results should be treated with caution.

3. BS 476 Part 7:1997

• Test conducted

This test was conducted in accordance with the procedure specified in BS 476 Part 7:1997 —Fire tests on building materials and structures Part 7. Method of test to determine the classification of the surface spread of flame of products.

• Test details Conditioning:

Prior to testing, the sample was conditioned,

to constant mass at a temperature of 23 ± 2 °C, and a relative humidity of 50 ± 10 %, and maintained in this condition until required for testing.

Exposed Face:

One face of the specimen was exposed to the flame. Specimen mounting:

Each specimen was placed into the specimen holder and backed with a non-combustible insulation board. So that no air gap was provide between the unexposed face of specimen and backing board.

• Test results

Note: Six specimens are usually tested. If the test on any specimen is deemed to be invalid, as defined in the standard, it is permissible for up to a maximum of nine specimens to be tested in order to obtain the six valid test results.

The classification limits specified in BS 476-7:1997 are given in Appendix 1. Observations during test:

In the case of specimen No.1, ignited at 57 sec. In the case of specimen No.2, ignited at 54 sec. In the case of specimen No.3, ignited at 54 sec. In the case of specimen No.4, ignited at 51 sec. In the case of specimen No.5, ignited at 53 sec. In the case of specimen No.6, ignited at 57 sec.

Criteria for classification:

If the prefix “D” or suffix “R” or “Y” is included in the classification, this indicates that the results should be treated with caution. An explanation of the reason for prefix and suffixes is given in Appendix 2

Appendix 2 Explanation of prefix and suffixes which may be added to the classification

1. A suffix R is added to the classification if more than six specimens are required in order to obtain six valid test results (e.g. class 2R).
2. A prefix D is added to the classification of any product which does not conform to the surface characteristics specified in the standard and has therefore been tested in a modified form (e.g. class D3).
3. A suffix Y shall be added to the classification if any softening and/or other behaviour that may affect the flame spread occurs

Classification: In accordance with the class definitions given in BS 476 Part 7:1997, the tested samples    are classified as class 1.

WARNING:

 The test results relate only to the specimens of the product in the form in which were tested. Small differences in the composition or thickness of the product may significantly affect the performance during the test and may therefore invalidate the test results. Care should be taken to ensure that any product, which is supplied or used, is fully represented by the specimens, which were tested.

The specimen was supplied by the sponsor and SGS-CSTC ANJI Branch was not involved in any selection or sampling procedure.
