25、 areas. It is the result of several factors thatinclude, but are not limited to, induced stresses in the basematerial, fabrication methods, and installation and thermalforces. While oil canning is an aesthetic issue, structuralintegrity is not normally affected. Oil canning is not groundsfor panel r

Structural Integrity5.1 Panel System Design:5.1.1 Structural panels shall be designed in accordance withthe Specifications for Aluminum Structures and in accordancewith sound engineering methods and practices.5.1.2 Defle

27、ction and serviceability shall be accounted for.10The deflection shall be limited so as to allow the roof toperform as designed. The substrate deflection shall not causestrains to the panels that affect the serviceability of the system.5.2 Panel System Testing:5.2.1 Static (Positive or Negative) Loa

31、movement between the paneland the structure to which it is attached shall be accomplishedby the use of concealed panel clips allowing such movement,except as provided in 7.3.7.3 When the building geometry and the rotational flexibil-ity of the support members permit, it is permissible to resolvether

32、mal movement through controlled rotation of the interme-diate structural members rather than movement within thepanel clip.7.4 Where insulation is applied between the panels andsupporting structure, the panel clips shall be designed to becompatible with the thickness and compressibility of the8Avail

Panel and Clip Anchorage8.1 Afixing line is required to anchor roof panels in order tomaintain end align

35、ment and to resist in-plane gravity andthermal force components.8.2 Fasteners that penetrate the roof surface are permittedonly at panel endlaps, penetrations, fixing lines, rib reinforce-ments, and at roof termination lines. Details at these locationsshall allow for the expected thermal movement.8.

36、3 Nails shall not be used where subject to withdrawalloads.9. Weather Tightness9.1 Panel-to-panel sidelap connections and endlaps shall beweathertight.9.2 Panels of maximum practicable lengths shall be used tominimize endlaps.9.3 Sealers:9.3.1 Sidelap SealerWhen the climate, roof slope, androof syst

37、em design warrant, the standing seam sidelap shallhave a sealer (see Note 3). When the sealer is factory applied,it shall remain in place and be protected during transit. In somecases, the panel geometry will provide the required protection.All sealers shall remain in place during panel installation

38、 andbe protected during storage and installation from any contami-nation and abrasion that unduly affects service.NOTE 3When the slope of the roof is steep, or when the roof systemis in a geographic area with little rainfall or snowfall, a sidelap or endlapsealer may not necessarily be required.9.3.

39、1.1 The sealer shall be of sufficient size and shape to fillthe maximum void to be sealed and to ensure compression afterengagement. The minimum compression shall be 30 % byvolume, or the adhesion plus webbing characteristics shall beas required to maintain watertightness.An appropriate test willbe

40、used to demonstrate the roof panel systems resistance toponded water. The sealer shall remain flexible between 0F( 18C) and 140F (60C) to allow engagement and shallshow no signs of cracking when tested in accordance with TestMethod C 765 (wrapped 180 over a 1-in. (25-mm) diametermandrel after4hat0F.

41、Thesealer shall not be exposed afterassembly.9.3.1.2 The sealer shall be sufficiently resilient to maintainthe seal after the movement of joints due to fluctuation inexternal load or expansion and contraction, or both. Whentested in accordance with Specification D 1667, the maximumset shall be 5 % i

42、f compression alone is required to maintainthe seal. The sealer shall be capable of maintaining the abovelevel of watertightness after exposure to the service tempera-ture range, 40F ( 40C) to 200F (93C) unless local orproject conditions justify that the specifier impose a differentrange. This water

43、tightness shall be independent of the tempera-ture at the time of panel installation.9.3.1.3 The sealer shall be noncorrosive and non-staining toadjacent materials and shall exhibit these characteristics aftertesting in accordance with Test Method D 3310, includingwater and with elevated temperature

44、 exposures for 21 days at160F (71C); the rating shall not exceed 2. The sealer shall befungus resistant and exhibit this property after testing inaccordance with Practice G21; the rating shall not exceed 1. Inmeat and poultry processing facilities or other areas requiringUSDA inspection, the sealer

45、shall be chemically acceptable toUSDA and shall be requested by the specifier. AppropriateFDAregulation(s) shall be included by the specifier when FDAcompliance is required.9.3.1.4 If the seam design utilizes sealant, and the locationof a clip component interrupts the sealant, the design shall notre

46、ly on differential movement between the panel seam and theclip component.9.3.1.5 If the sidelap sealer is interrupted by the installationof a sidelap clip, and if required by the panel system design, theseal shall be completed around the clip. The performancecharacteristics of the supplemental seale

47、r shall be equal to theprimary sidelap sealer. Both sealers aging characteristics shallsustain the above performance during the design service life ofthe roof.9.3.2 Endlap SealerThe panel endlap shall be sealed witheither field-applied tape or cartridge-type sealer, or both (seeNote). The endlap sea

48、ler shall be equal in performance to thesidelap sealer. Minimal sealer exposure shall be allowed afterinstallation.9.3.2.1 The following requirements shall apply additionally.Cartridge sealers shall remain fluid, and sealing tapes shallrelease cleanly from any backing paper at temperatures rangingfr

49、om 0F ( 18C) to 140F (60C). Backing paper shallrelease cleanly after exposure to moisture and when tested inaccordance with Test Method C 879 using the Procedure,Alternative A. Tape sealers shall exhibit no cracks or loss ofadhesion after exposure in accordance with Test Method C 765with the modified 0.25-in. (6-mm) mandrel requirement (bent180 over a 0.25-in. mandrel). Cartridge-type sealers shall betested in accordance with Test Method C711. When required,Test Methods C 765 and C711shall both be modified using acold temperature preparatio
