Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTERevised 5.4 editorially in July 2017.1. Scope1.1 This test method covers the evaluation of ceramic floorti

19、 cast into the foundation extension to hold thedrive base.5.2 TesterThe tester itself shall be a 150 6 5-lbs (68.1 62.3-kg) carriage, consisting of a piece of12-in. thick, hot-rolledsteel plate in the shape of an equilateral triangle with 6-in.(152-mm) radius rounded corners and having a 338-in. (85

20、.7-mm) diameter hole in the exact center. Three swivel casterwheels shall be equally spaced in a circle with 15-in. (381-mm)radius from the center and fastened to the underside of thecarriage at the intersection of the bisector of each angle and the15-in. (381-mm) radius circle. Over each wheel a 16

21、-in.(406-mm) high, 1-in. (25.4-mm) diameter, fully threaded steelrod shall be vertically threaded into the carriage to permit theaddition of up to 250 lbs (113.5 kg) of auxiliary weights to eachwheel. The auxiliary weights with 112-in. (38-mm) diametercenter openings shall weigh either 25 or 50 lbs

22、(11.5 or 23 kg)each and when stacked on the threaded rod, their totalthickness shall not exceed 15 in. in height. They shall be helddown firmly by a washer and nut on the threaded rods. If theweight of the carriage with wheels and threaded steel rods, butwithout auxiliary weights, does not reach the

23、 required weightof 150 6 5 lbs (68.1 6 2.3 kg), one third of the necessaryadditional weight shall be permanently added near each steelrod by welding it in place. Conversely, if the total weight of thecarriage exceeds the required weight of 150 6 5 lbs (68.1 62.3 kg), a sufficient number of 1-in. dia

24、meter holes may bedrilled into the steel plate, equally distributed along the threesides of the triangle, to reduce the weight. A cutaway diagramof the apparatus is shown in Fig. 1.25.3 DriveThe tester shall be driven by a34-hp motor andspeed reducer. Drive transmittal shall be arranged in such aman

25、ner that the plane of travel and the elevation of the carriageare free to accommodate various types of test slabs. Thecarriage shall rotate at the rate of 15 6 0.5 rpm.5.4 WheelsThe wheels shall be swivel casters with remov-able axles, equipped with grease fittings. They shall be 4 in. indiameter an

26、d have a 138-in. bearing surface. Three differentsets of three wheels each are required, namely one set with asoft rubber bearing surface of 78 6 3 Shore A durometerhardness, one set with hard rubber bearings surface of 80 6 3Shore D durometer hardness, and one set with steel bearingsurface. All cas

32、 Base for Portland Cement InstallationsArecommended mortar base panel for portland cement installa-tions may be cast without reinforcements into a 2-in. (51-mm)thick regular octagon, measuring 4 ft (1220 mm) from side toside, from a mortar mix consisting of six parts by weight of drysand, clean and

33、graded (see Specification C144) and one partby weight of portland cement (Type I of Specification C150),with enough potable water to make a relatively dry mortarwhich, when stroked with a trowel, gives a smooth, slickappearance. One half-inch (12.7-mm) diameter, 11-in. (280-mm) long sections of pipe

34、, centered and projecting about 5 in.(127 mm), may be horizontally cast into alternate sides of theoctagon to serve as lifting handles for the panel. A 6-in.(152-mm) square opening in the center of the octagon admitsthe drive shaft of the tester. For conventional-type installationmethods, the tile s

35、hall be set before the mortar hardens. Afterproper curing, such a panel is set in place on the foundation ofthe testing machine with a weak plaster. A polyethylene sheetshall be laid between the foundation of the tester and theplaster, so that the mortar-base test panel can be easily removedafter co

36、mpletion of the test. A plaster mix of ten parts byweight of dry sand, clean and graded (Specification C144) andone part by weight of gypsum plaster with enough potablewater to make a fairly thick slurry has been found satisfactory.Construction details for such a panel are shown in Fig. 3.6.1.2 Conc

37、rete Base for Thin-Bed InstallationsThe sizeand construction of such a concrete base shall be the same asthat described under 6.1, except that the concrete mix shallconsist of three parts of gravel not over34 in. (19 mm) in size,two and one-half parts of dry sand, clean and graded (Speci-fication C1

38、44), one part of portland cement (Type I ofSpecification C150) and one part of potable water, all parts byweight. The concrete base panel shall be cured for at leastseven days before the installation of tile. The concrete base isset in place on the foundation of the tester with plaster asdescribed i

39、n 6.1.1.6.1.3 Plywood Base for InstallationsThe plywood baseshall be 4 ft (1220 mm) square and of sandwich construction.For maximum stiffness, the plywood face grain directionshould be installed so as to run perpendicular to the floor joistor supports. The top shall consist of two sections of1932-in

40、.tongue and groove plywood (or as otherwise specified) suchthat the joint between the two sections runs perpendicular tothe joists and tangential to the center of the wheel path (wheelsare 138-in. wide). The bottom shall be14-in. (6.4-mm)plywood. In between the top and bottom of the panel on 16-in.(

41、406-mm) centers, shall be four 158-in. (41.4-mm) square and4-ft (1220-mm) long sections of wood to duplicate the supportrendered by joists in an actual installation. There shall be a6-in. (152-mm) square opening in the center of the panel toFIG. 2 Deflection Gage (Not to Scale)Dimension TableKey in.

Such a panelshall be set in place on the foundation of the testing machinewith plaster as described in 5.1, but a polyethylene sheet shall

43、also be used between the plywood base and the plaster to keepmoisture out of the wood. The panel shall be held in place onthe foundation of the testing machine with four bolts, one ateach corner. The bolts fit into the “Star Tamp-Ins” cast into thefoundation and secure the lower14-in. (6.4-mm) plywo

For details of construction of such a panel seeFig. 4.6.1.3.1 Plywood Base with Panel-Type Underlayment

45、If apanel-type underlayment (for example, backerboard) is to beinstalled atop the plywood base, it shall consist of two sectionssuch that the joint between the two sections runs parallel to thejoists and tangential to the center of the wheel path (wheels are138-in. wide). A 6-in. (152-mm) square ope

46、ning in the centerof the underlayment shall align directly with the plywood baseto permit entry to the testing machine drive shaft. See Fig. 5 foran illustration.6.1.4 Composition Base for InstallationsThe constructionof the composition base panel shall be identical to that of theplywood base, excep

47、t that the top of the panel consists ofcomposition board or other sheeting material as specified. Thesame method shall be used to set the composition base on thefoundation of the machine and to fasten it to the foundation asoutlined in 6.1.3.7. Testing Procedure7.1 Prepare a test panel assembly usin
