35、All materials shall be exactly as identified on theinspection documents.8.4 All materials used in fire stops shall have been tested orevaluated as part of the system in accordance with Test MethodE814 or UL 1479-94 as required by the building code or firecode, or both.E2174 1029. Inspection Schedule
36、9.1 The inspector and installer shall mutually agree upon aschedule for the notification of the following:9.1.1 Inspection of fire stop materials,9.1.2 Start of installation, and9.1.3 Anticipated completion of inspection.9.2 The inspection schedule shall not interfere with theinstallation process.9.
37、3 The installer shall notify the inspector within 1 workingday when any item agreed to on the schedule must be changeddue to unforeseen circumstances, such as material delays,project change orders, or other installation conflicts.10. Inspection10.1 The inspector shall be permitted to enter the premi
38、sesto 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 and locate fire rated assemblies on the proj
39、ect thatare subject to the installation of fire stops.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 received for the installation of the fire st
40、op 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 fire stop installation and record this informa-tion on the inspec
41、tion 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 fastening of materials, and10.6.4 The prepa
42、ration 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 verify and document that the firestops r
43、equired in the inspection documents have been installed.10.9 The inspector shall verify that every fire stop inspectedas required by 10.12.2 is in accordance with one of thedocuments specified in 7.4.10.10 The inspector shall verify that every fire stop in-spected as required by 10.12.2 is in accord
44、ance with themanufacturers instructions.10.11 The inspector shall verify compliance of the fire stopby observing the installation process and by taking andrecording measurements of the substrates and materials beinginstalled or by destructive examination of completed installa-tions.10.12 Inspection
45、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 type of fire stopbeing installed, or10.12.2 The inspector sha
46、ll conduct a post installationinspection, which shall require destructive type verification ofthe fire stop and repair of the fire stop. A minimum of 2 %, butnot less than one, of each type of fire stop shall be inspected perfloor or for each area of a floor when a floor is larger than10 000 ft2(946
47、.7 m2). An area consists of 10 000 ft2or less.NOTE 7The AA should determine the types of fire stops and subse-quently the number of each type that is to be inspected. The determinationof a “type” will typically be a function of a unique combination ofparameters, including penetrant type (for example
48、, metal pipe, plasticpipe, cabling), fire stop material or device (for example, intumescentcaulk, collar, sealant), and penetrated substrate (for example, gypsumwall, concrete floor, composite floor deck).10.13 Any type of fire stop noted in 10.12.2 that does notcomply with the inspection documents
49、will require repair orreplacement and re-inspection of that fire stop plus one fulladditional inspection, of the number specified in 10.12.2,ofthat type fire stop. If non-compliance occurs on 10 % or moreof the quantity of like fire stops within 10.12.1 or 10.12.2, theninspection of those particular type fire stops shall cease. Theinstaller shall inspect their own work, repair or replace thoselike fire stops within the area prior to re-commencement ofinspections by the inspector.10.14 All observed deficiencies shall be documented andmarked on the
