Materials8.1 The inspector shall verify that the materials and systemsused for firestopping have been tested in accordance with TestMethod E814 or UL 1479-94, and are listed and l
34、abeled for theuse intended.NOTE 6Listed and labeled refers to materials, devices or assembliesthat have been tested by an accredited testing laboratory after which thetest results and description of the materials, devices or assemblies areE2174 14a2published by an accredited quality assurance agency
35、 and the materials,devices or assemblies bear a Listing Label.8.2 All materials shall bear a Listing Label as defined in3.2.9. Manufacturers container labels shall include the manu-facturers name, product name and product description. Othercomponents of the firestop shall also be identifiable by lab

37、 fire code, or both.9. Inspection Schedule9.1 The inspector and installer shall mutually agree upon aschedule for the notification of the following:9.1.1 Inspection of firestop materials,9.1.2 Start of installation, and9.1.3 Anticipated completion of inspection.9.2 The inspection schedule shall not
38、interfere with theinstallation process.9.3 The installer shall notify the inspector within oneworking day when any item agreed to on the schedule must bechanged due to unforeseen circumstances, such as materialdelays, project change orders, or other installation conflicts.10. Inspection10.1 The insp
39、ector shall be permitted to enter the premisesto review the applicable inspection documents, to observe theinstallation in progress, to inspect completed work and toperform overall functions relative to their duty as inspector.10.2 The inspector shall use the inspection documents in 7.3to identify a
40、nd locate fire rated assemblies on the project thatare subject to the installation of firestops.10.3 The installer shall notify the inspector of the arrival ofthe materials (described in 8.1 8.4 inclusive) as agreed to in9.1.10.4 Prior to installation, the inspector shall verify that allmaterials re
41、ceived for the installation of the firestop meet therequirements of 8.1 8.4 inclusive and record this informationon the inspection form.10.5 Prior to installation, the inspector shall verify anyconstruction detail on the inspection documents that will not bevisible after the firestop installation an
42、d record this informationon the inspection form.10.6 The inspector shall not supervise or in any mannerdirect any aspect of the installation process. This includes, butis not limited to, the following:10.6.1 Handling and storage of materials,10.6.2 The mixing of materials,10.6.3 The cutting or faste
43、ning of materials, and10.6.4 The preparation of substrates.10.7 When work is started or completed per the schedule inSection 9, the installer shall notify the inspector. Inspection ofcompleted work shall take place within two working days fromnotification by the installer.10.8 The inspector shall ve
44、rify and document that thefirestop systems required in the inspection documents havebeen installed.10.9 The inspector shall verify that every firestop systeminspected as required by 10.12.2 is in accordance with one ofthe documents specified in 7.4.10.10 The inspector shall verify that every firesto
45、p systeminspected as required by 10.12.2 is in accordance with themanufacturers instructions.10.11 The inspector shall verify compliance of the firestopsystem by observing the installation process and by taking andrecording measurements of the substrates and materials beinginstalled or by destructiv
46、e examination of completed installa-tions.10.12 Inspection frequency shall depend on the method ofinspection and the scope of the project. The method ofinspection shall be one of the following:10.12.1 The inspector shall be on site during installation andrandomly witness a minimum of 10 % of each ty

An areaconsists of 10 000 ft2or less.NOTE 7The AA may determine the types of firestop systems andsubsequently the number of each type that is to be inspected, in additionto the minimum required by this standar
49、d. The determination of a “type”will typically be a function of a unique combination of parameters,including penetrant type (for example, metal pipe, plastic pipe, cabling),firestop material or device (for example, intumescent caulk, collar,sealant), and penetrated substrate (for example, gypsum wall, concretefloor, composite floor deck).10.13 Any type of firestop system noted in 10.12.2 that doesnot comply with the inspection documents will require repairor replacement and re-inspection of that firestop system plusone full additional inspecti
