A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEDesignation was changed to dual and units information was corrected editorially in August 2015.1. Scope1.1
3、 This practice covers guidelines for application ofsprayed fiber and cementitious fire-resistive materials.1.2 This practice is general in nature. It is not intended tocover all requirements for application.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as
4、standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns, if any,
5、 associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

Fire Resi
20、stance Classifications9.1 GeneralRequired fire resistance classifications areoutlined by building codes such as those published by BOCA,3SBCCI,4ICBO5and enforced by local authorities havingjurisdiction. Required fire resistance classifications are deter-mined by construction type, occupancy, and loc
21、ation.9.2 Architects and material specifiers shall indicate onconstruction drawings and in specifications the required fireresistance classification(s) for a project. They shall also indi-cate what elements of that project are to be so protected. (SeeNote 1.)NOTE 1The architect and material specifie
22、r may indicate on construc-tion drawings and in specifications a reference number for a fire resistancesystem capable of providing the required protection.10. Safety10.1 Current OSHA, applicable local ordinances, or coderegulations shall be followed at all times.10.1.1 Equipment shall have safety gu
23、ards that meet appli-cable OSHA regulations in place. Grounded electrical connec-tions shall be used.10.1.2 Protective EquipmentAll persons in the applicationarea shall wear protective equipment as required. Examples ofequipment that may be needed are: respirators, dust masks,coveralls, goggles or s
24、afety glasses, and hard hats.10.1.3 Workmen shall not wear loose fitting clothing thatcould become caught in the machinery. However, that person-nel actually spraying product may wear loose, long sleeveclothing for protection and comfort reasons.10.1.4 ScaffoldWhen required, a strong, lightweight,st

Substrate Preparation11.1 Prior to the application of SFRM, all areas to besprayed shall be inspected by the applicator to ensure a suitablesurface for proper SFRM bonding. The following recommen-dations shall be followed:11.1.1 All surfaces to be sprayed shall
27、be free of dirt, grease,oil, mill scale, loose scale, loose rust, or any material that willimpair proper adhesion.11.1.2 CleaningThe applicator shall bring to the generalcontractors attention any surface that does not meet therequirements of 11.1.1. Responsibility for cleaning substratesshall be est
28、ablished prior to submittal of SFRM bid. Unaccept-able surfaces shall be cleaned in accordance with substrate orSFRM manufacturers recommendations. (On asbestos removalprojects it is necessary to coordinate substrate conditions andcleaning procedures to ensure the integrity of the post removalencaps
29、ulant coatings.)11.1.3 MaskingSurfaces that are susceptible to damageand are not to be sprayed shall be masked, covered orotherwise protected from the overspray of SFRM.11.1.4 Painted SurfacesSFRM manufacturers generallydo not recommend application to painted surfaces. If it hasbeen established that
30、 a paint or primer is necessary, the primedsubstrate sprayed with SFRM shall be tested in accordancewith Test Methods E119.11.1.5 Post removal encapsulated surfaces (lockdown coat-ings) shall be inspected in accordance with Practice E1368.Ifit has been established that a lockdown coating is necessar
31、y,the coated substrate sprayed with the SFRM shall be tested inaccordance with Test Methods E119.11.1.6 Where UL fire resistance rating designs are utilized,unless specifically prohibited in a design, SFRM may beapplied to primed or painted wide flange steel shapes provided:the beam flange width doe

34、column flange width does not exceed 400 mm 16 in.; thebeam or column web depth does not exceed 400 mm 16 in.;and bond tests conducted in accordance with Test MethodE736 shall indicate a minimum average bond strength of 80 %and a minimum individual bond strength of 50 % whencompared to the bond stren
35、gth of the fire resistive coating asapplied to clean uncoated18 in. 3.2 mm thick steel plate. Theaverage minimum bond strength values shall be determinedbased upon a minimum of five bond tests conducted inaccordance with Test Method E736.12. Application Environment12.1 General:12.1.1 A minimum ambie
36、nt and substrate temperature of4.4C 40F shall be maintained for 24 h before, during, anda minimum of 24 h after the application of the SFRM unlessotherwise recommended by the material manufacturer. Ifnecessary for job progress, enclosures and heat shall beprovided to maintain temperatures.12.1.2 In
37、most instances, natural ventilation is sufficient. Inenclosed areas, forced ventilation shall be introduced forcuring.13. Application13.1 GeneralSFRM shall be applied by an experiencedfirm. The firm shall be licensed or otherwise approved to applythe SFRM.13.1.1 Equipment, mixing, and application sh
38、all be in ac-cordance with SFRM manufacturers written specifications andapplication instructions.13.1.2 Application shall not start until SFRM applicatorinspects the substrates to receive protection and they are foundacceptable.13.1.3 Work shall be coordinated with other trades so thatproject progre
39、ss is not delayed. Application of SFRM shall becompleted prior to the installation of duct work, piping,conduit, and other suspended items. Hangers for these itemsmay be installed prior to SFRM application, thus reducingsubsequent SFRM damage.13.1.4 SFRM shall be applied after all roof construction,
40、installation of roof-top HVAC equipment and other relatedwork is completed.13.1.5 Bonding adhesive or other surface preparation shallbe used when required and as recommended by SFRMmanufacturer.13.1.6 No SFRM shall be applied to steel deck prior tocompletion of concrete work on steel deck.13.1.7 Sur
41、face sealers are optional. When used, the surfacesealer shall be as recommended by the SFRM manufacturerand shall be applied in accordance with the SFRM manufac-turers written application instructions.14. Protection During Curing14.1 SFRM are susceptible to damage while they are curing.Precautions s
42、hall be taken to allow the materials to curewithout physical abuse.14.1.1 Heating and ventilation shall be provided whenneeded for curing (see 12.1).14.1.2 No roof traffic shall be allowed during application orduring the curing period of the SFRM applied to the roof.(WarningRoof traffic at any time
43、after the SFRM is fullycured shall be avoided if possible. Excessive traffic, loading orimpact, can cause SFRM delamination.)14.1.3 Care shall be taken so that deflection or impactgreater than the SFRM manufacturers recommended limits donot occur. The maximum allowable steel deck deflection shallbe
44、determined in accordance with Test Method E759/E759Mand the effects of impact shall be determined in accordancewith Test Method E760/E760M.15. Inspection Procedures15.1 An independent testing laboratory shall inspect theapplied SFRM upon the completion of each floor for thicknessand density in accor
45、dance with Test Methods E605/E605M.15.2 Results of thickness and density testing shall be madeavailable to the SFRM applicator before application progressesmore than two floors beyond the floor in question.15.3 Where required by contract documents or buildingcode authority, the SFRM shall be tested
46、upon curing forcohesion/adhesion in accordance with Test Method E736 by anindependent testing laboratory.15.4 Results of cohesion/adhesion testing shall be madeavailable to the SFRM applicator as soon as practical. Depend-ing upon job scheduling and jobsite conditions, it may not bepossible to condu
47、ct cohesion/adhesion tests in a timely manner.16. Patching16.1 PatchingIn areas where the SFRM has beenremoved, it shall be resprayed or patched with the samematerial or with a compatible material as determined by a firetest.16.2 Patching shall be done by the SFRM applicator.Responsibility for payme
48、nt of patching shall be decided priorto bid submittal.17.
