In some cases the wall orceiling covering system will be supported by a frame systemsome distance away from the wall or ceiling covering material.4. Summary of Practice4.1 This practice describes procedures for specimen prepa-ration and mount
23、ing when testing textile, paper or polymeric(including vinyl and expanded vinyl) wall or ceiling coveringsto assess flame spread and smoke development as surfaceburning characteristics using Test Method E84.5. Significance and Use5.1 Textile, paper and polymeric (including vinyl and ex-panded vinyl)
24、 wall or ceiling coverings and wall or ceilingcovering systems used as interior finish are often evaluatedwith Test Method E84 to comply with building or life safetycode requirements. This practice describes specimen prepara-tion and mounting procedures for such materials and systems.5.2 This practi
25、ce is not applicable to the following materi-als:5.2.1 Wall or ceiling coverings with exposed wood surfaces,and5.2.2 Any wall or ceiling covering system where the toplayer is not a textile material, a paper-based material, apolymeric material or a vinyl material.6. Conditioning6.1 The test specimens
26、 shall be conditioned as described inthe section on specimen conditioning in Test Method E84.7. Test Specimens7.1 The test specimen sizes shall comply with those de-scribed in the test specimen section of Test Method E84. Thetest specimens shall be butted against the vent end of the firetest chamber
27、 and shall consist of a continuous, unbrokenlength, or of sections joined end-to-end. The test specimensshall have a width of 20 to 24 in. (510 to 610 mm), a length of24 ft + 12 in. 6 in. (7.32 m + 305 mm 152 mm) and amaximum thickness of 4 in. (101 mm).7.2 The wall covering system test specimens sh
28、all beprepared as described in Section 8.8. Test Specimen Preparation8.1 Whenever a wall or ceiling covering system uses anadhesive to attach a wall or ceiling covering material, theadhesive specified by the manufacturer shall be used forconstruction of the test specimen in accordance with the wall
29、orceiling covering manufacturer application instructions.8.1.1 If the wall or ceiling covering system is a factory-produced wall panel, the adhesive shall be the same one usedin the manufacture of the factory-produced wall or ceilingpanel.8.2 Wall or Ceiling Coverings Intended to be AppliedDirectly

(15.9 mm)thick Type X gypsum board, complying with SpecificationC1396/C1396M. The gypsum board shall not be required to bemounted on studs. Mount the spec
33、imens on the ledges of theTest Method E84 furnace without using additional means ofsupport.8.3.1 Whenever a wall or ceiling covering has been testedusing the test specimen described in 8.3 (over gypsum board),it shall not be required to be additionally tested mounted on afiber-cement board.8.4 Wall
34、or Ceiling Coverings Intended to be Applied over aWood SubstrateIf the wall or ceiling coverings are intendedto be applied over a wood substrate, the specimens shall consistE2404 102of the wall or ceiling covering mounted on untreated plywood,with a face veneer of Douglas fir. The plywood shall have
35、 thesame thickness as the wood substrate used in field practice, andshall comply with NIST Voluntary Product Standard PS 1-07,Structural Plywood. The plywood shall carry a grade stampindicating that the plywood has been graded PS 1-07 A-B andis for exterior exposure. The plywood shall contain a grad
36、estamp issued by a quality control agency. Alternatively, theplywood shall be permitted to be stamped as conforming toCSA Standard O121 (Douglas fir plywood). Mount the speci-mens on the ledges of the Test Method E84 furnace withoutusing an additional means of support.8.5 Wall or Ceiling Coverings I
37、ntended to be Applied overSubstrates other than Wood, Gypsum Board or Noncombus-tible SurfacesIf the wall or ceiling coverings are intended tobe applied over substrates other than wood, gypsum board ornoncombustible surfaces, the specimens shall consist of thewall or ceiling covering mounted on the
38、substrate to be used infield practice. Mount the specimens on the ledges of the TestMethod E84 furnace without using an additional means ofsupport.8.6 Wall or Ceiling Coverings Not Intended to be AdheredDirectly to a Wall or Ceiling Surface, but Intended to beOtherwise Supported by Framing or a Trac
39、k SystemThespecimens shall be prepared in accordance with the require-ments of Practice E2573, in the same way that specimens ofsite-fabricated stretch systems are prepared.9. Testing of Specimens9.1 All testing shall be conducted using the methodologydescribed in Test Method E84.10. Operator Safety
40、10.1 The primary concerns for operator safety are associ-ated with the fire-test-response procedure, Test Method E84,and not with the specimen preparation procedure. Safetyrecommendations are included in Test Method E84.11. Report11.1 Report a detailed description of the system beingtested.11.2 Repo
41、rt a detailed description of the specimen prepara-tion method used, including the adhesive, if used, and itsapplication rate, per Section 8.11.3 Report all the information required in the reportingsection of Test Method E84, including observations, graphicalresults and the values of the flame spread
