If necessary, gently abrade the upper and lower surfaces of the core with grade
13、60 abrasive paper until the surface area ground is approximately 50 % of the total surface area 3.2 Number of test specimens Prepare a minimum of five test specimens. 4 Procedure 4.1 Test conditions Unless stated otherwise in the manufacturers specifcation, carry out the tests at 23 OC f 2 OC and 50
14、 % f 5 % relative humidity. 4.2 MethodA 4.2.1 Total thickness Set the plunger of the thickness gauge directly on the plane reference plate. Record the reading on the dial (zero reading). Place the prepared core between plunger and plate. Record the reading on the dial (measurement reading 1). 4.2.2
15、Layer thickness Gently abrade the top layer with grade 60 abrasive paper until approximately 50 % of the bottom layer is visible. Replace the core between plunger and plate and record the reading on the dial (measurement reading 2). 4.3 Method B 4.3.1 Force the thickness measuring probe into the sur
16、face under test, using hand pressure, until one or more of the steel probes comes into contact with the Substrate. NOTE Care is required when testing surfaces instailed over macadam or asphalt, to ensure that the probes do not penetrate any soft areas or voids in the substrate. Without moving the pr
17、obes, adjust the sliding bmel until it is in contact with the upper surface of the surface under test, and read off the thickness from the calibrated barrel. 4.3.2 If necessary, make allowance for any surface texture which may be present by laying a reference sample with an identical surface texture
18、 over a steel plate, placed adjacent to the test area, and measure the thickness as given in 4.3.1. Remeasure the thickness of the reference sample as given in 4.2. 5 Calculation and expression of results 6.1 Method A Calculate the total thickness and layer thickness of each test specimen as follows
19、: Total thickness: Total thickness, in millimetres, is given by measurement reading 1 minus zero reading. Layer thickness: Layer thickness, in miliimetres, is given by total thickness minus measurement reading 2. Express the results to the nearest 0,i mm. 6.2 Method B Where necessary, apply the foll
20、owing correction factor to all individual measurements: Correction factor, in miliimetres, is given by thickness of the reference sample using method B, in millimetres, minus thickness of the reference sample using method A, in millimetres. Express results to the nearest 0,5 mm. 6 Test report The te
