j I INTRODUCTION

1.1 This report provides evaluation ~€sults per ASTH E84 (798) Standard on a c04ting material manufact~red by Miraco, lnc. and designated as HlRACOTE.

1.2 This report supersedes Factory Mutual's Report OA8Q4.AC dated I April 27, 1978 whi ch cot'ltained the rEsults of three tests conduc ted 011__ '"'''''''''''''----'-''' MIRACQTE··when'''·evari.isE~d''··p'~i··ASTM-ES'z;.-' (75TStaRdard~--··_· __·_···n ,-.--- ­

] lishing product performance per the 1979 Standard. The tE~t~ referenced in this ~eport are 85 recorded in the F.M. Report OABQ4.AC.

1.4 The tests were conducted in accordance ~ith the Standard Method ofJ Test for Surface Burning Characteristics of Building Materials, ASTM Designa­tion E~84. The results yield flame spread aqd ~oKe density v~lueg for the tested material during a 10 minute fire exposure.

I 1.5 The purpose of the cest is to determine the comparative surfac~ burn­

ing characteristics of building materials by evaluating the flam~ spr~ad p2r­

J fo~ance of red oak under identical conditions. The smoke density of the mateTial may be compared wi~h that of ~spesto~-cement and red Qak which have been a~bitr~rily established as 0 and 100 respectively.

1 1.6 The tests were ~onducted at the Factory Mutual Research C~rporation

In Norwood t Massachusetts.

I II MATER!AL DESCRIPTION

I 2.1 MIRACOTE is an eld5tom~ric coating mate~i~l ~hich can be used on both

interior and exterior building surfaees.

2.2 MlRACOTE is compose~ of dry mineral a~greg3te combined with a proprietary dry compound, which ~DgetheT i$ mixed with a liquid catalyst.

2.3 The material was brush applied to 1/4 inch C6.35 ~) thick asbestos cement board at a nominal thickness of .075 inch (l.~ ~).

2.4 ' ·The manufacture of the product ~nd the preparation of the test apeciweu& we~e witnessed by a representative of Factory Mutual. FOI~ulation

and physical specifications of the product are on file at Factory Mutual.

III TES'!" MEtHOD

3.1 The furnace, constructed to ASTM E-84 (15) 5pecific~tions. Wa3 pre~

heated fo~ a 10 minute pBriod with the asbestos-cemept board and th~ ~~mov8ble

top in place. During this time, the exposure flame and draft conditions ~er~

adjusted to meet the ASTM £~84 requirementS of 5,000 btu (5.3 MJ/min.) produc­ing a 4-1/2 ft. (1.37 m) flame length Yith an air v~lo¢it1of 240 + 5 ft/min.) (73.2 + 1.5 m/min.).

3.2 Under: these cQnditlons ..nth red oak flooring having. a moisture con~

tent of 6 to 8%, the flame sp~ead~ 19-1/2 ft. (5.94 m) frum the end of the igniting flame in 5 min. 30 ~~C. + 15 g~C.

3.3 The £~rna~~ was allowed to cool until the brick tempe~ature was lOS + 50f (40.5 + 2.S0C) as measu~~d by a thermocouple ~bedded 1/8 ~n.

(3.175 mm) below-the surface of the furna~e floor a~ a point 13 ft. (3.96 m)

from the burners.

3.5 During the test, the advancement of the flame front was noted ViSu­ally th't""ough the vie1.!ing por::slocated on the side of the furnac:t:. Smoke emission ~as continuously monito~ed by a photo~lectric circuit mo~nted verti~

cally ucross a hori 4 oncal section of the flue pipe.

3.6 The ~bove test procedure was followed for the th~ee tests.

IV FLAME SPREAD DETERMINATION

4.1 The fla~e spread distances versus ti~e are plotted to establish a '.-". curve for ~he J:ll'lt~rial tested. Ihe total (At) under the flame-, spread time

distance curve is determined while ignoring any flame: front recession. The flame spread distance is the observed di9tance minus ehe:4-1/Z ft. (1.37 m) due to the ignition fire.

4.2 The Flame Spread Index (lSI) shall be determined ~s follows;

4.2.1 If this tocal area (At) is less than or equal to 97.5 ft-min., the Flame Spread Index shall be 0.515 times the total area (FSC ; 0.515 At).

4.2.2 If the total area (At) is greater than 97.5 ft-min., the Flame Spread Index ~hal1 be 4900, divided by the difference of 195 minus the total 3Te& (At), (FSC a 4900/(195-At )).

IX AUDIT INSPECTION AND RE~E~~INATION

9.1 A manUfacturing and quality control audit inspection will be con­ducted periodically on the listed p40duct at the Allied Block Chemical Company facility in Ne~. Eagle. pennsylvania to determine that the quality a.nd unifom­i~y oiche product has been maintained and will provide the same level of per­formance as originally tested.
