Summary of Test Method4.1 Straight lines are marked at various locations on the floor surface. Point eleva
23、tions are then measured at regular 300-mmintervals along each line. The elevation differences between all adjacent reading points are calculated, and a straight lineapproximation to the surface profile along each measurement line is produced and evaluated for consistency with visualobservation of th
24、e floor surface.4.2 The arithmetic differences between all adjacent 300-mm elevation differences and the elevation differences between allpoints separated 3 m are then calculated. Estimates of each test sections floors FF Flatness and FL Levelness F-Numbers areobtained through statistical analyses o
25、f these calculated profile values. Finally, the F-Numbers for each test section are combinedto arrive at a composite set of F-Numbers for each test surface.5. Significance and Use5.1 This test method provides statistical (and graphical) information concerning floor surface profiles.5.2 Results of th
26、is test method are used primarily to:5.2.1 Establish compliance of randomly trafficked floor surfaces with specified FF Flatness and FL Levelness tolerances,5.2.2 Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and5.2.3 Investigate the curling
27、 and deflection of floor surfaces.E1155M 1425.3 Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installationsprimarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors).NOTE
28、2When the traffic patterns across a floor are random, (as is generally the case) evaluation of the floors FF Flatness and FL Levelness willnecessarily involve a random sampling of the surface, since all of the infinite potential profiles to be seen by the traffic can not possibly be measured.In thos
29、e instances when the traffic across a floor will be confined to specific paths, however, the requirement for random sampling is eliminated, sincethe floor can indeed be inspected exactly as it will be seen by all of the traffic. In these special cases, rather than inferring the condition of the traf
30、fic pathsfrom a random sample, it is far more useful to measure each of the traffic paths directly using continuous recording floor profilometer configured to runexactly in the traffic wheel paths. Such direct simulation measurements eliminate the inherent uncertainties of statistical sampling and p

Organization of Test Are

40、as a unique specified set of tolerances must be treated as a separatesurface.7.2 Test SectionA test section shall consist of any subdivision of a test surface satisfying the following criteria:7.2.1 No test section shall measure less than 2.4 m on a side, nor comprise an area less than 12 m2.7.2.2 N
41、o portion of the test surface shall be associated with more than one test section.7.2.3 When testing a concrete floor, no test section boundary shall cross any construction joint.7.3 Sample Measurement LineA sample measurement line shall consist of any straight line on the test surface satisfying th
42、efollowing criteria:7.3.1 No sample measurement line shall measure less than 3.3 m in length.7.3.2 When testing a concrete floor, no portion of any sample measurement line shall fall within 600 mm of any slab boundary,construction joint, isolation joint, block-out, penetration, or other similar disc

44、.7.3.3 Measurement lines may not be placed parallel to each other closer than 1.2 m.7.4 Type I Test Sample (Measured With Type I Apparatus)AType I test sample shall consist of not less than twelve sequentialpoint elevation measurements made at regular 300-mm intervals along a single sample measureme
45、nt line.7.5 Type II Test Sample (Measured With Type II Apparatus)A Type II test sample shall consist of not less than elevensequential measurements of the elevation differences between adjacent reading points spaced at regular 300-mm intervals alonga single sample measurement line.7.6 Minimum Number
46、 of zi Readings Per Test SectionThe number (or length) of Type I or Type II test samples to be collectedwithin each test section shall be sufficient to yield (in aggregate) not less than Nmin individual measurements of zi, where Nmin iscalculated as follows:Nmin52=A 12#A#150! (1)5A/3A.150!where:A =
47、test section area, m2.A = test section area, m27.7 Construction JointsWhere construction joints are required to be measured, periodic measurements of the 600-mmcurvature qi shall be taken, transverse to and centered on the construction joint.At least one qi measurement shall be taken on eachstraight
48、 section of joint, with a maximum interval between measurement locations not to exceed 3 m. These measurement locationsshall be recorded.NOTE 4Since construction joints are a discontinuity in the floor surface, measuring across them would introduce statistical anomalies into this testmethod. Constru
49、ction joints are therefore excluded from the generation of F-Number statistics. However, since traffic will nevertheless pass across manyof the construction joints, a separate measurement and analysis of the joints may be required in order to provide a quantitative measure of the roughnessof the joints themselves. Some joints may never see traffic, for example, those along a wall. The particular joints required to be analyzed may be specifiedin contract specifications, along with a maximum allowable value for q
