SAE J1015 Revised JUL2012 Page 3 of 8 5. PREPARATION FOR TESTS 5.1 Tires Tires shall be prepared for thermocouple probes
10、 by drilling 3 mm diameter holes from the tread surface to the top of the topmost reinforcement; i.e., breaker cord, belt cord, or carcass ply. These holes, drilled normal or perpendicular to the tread surface, shall be located across the tread in such a pattern that one or more are within 25 mm or
11、less of the hottest point in the tire. To insure this, the following procedure is recommended. 5.1.1 Drill Hole Location 5.1.1.1 With a caliper, measure the total tire thickness of each tread element around the tire at the centerline and shoulder. Determine the area around the circumference with the
12、 greatest total thickness. 5.1.1.2 Select a tread bar or contiguous tread element in this heavy gauge area as the probe location. 5.1.1.3 For tires of 16.00 cross section and smaller, locate holes in the center of the cross lug or contiguous tread element and at maximum increments of 25 mm from the
13、tire centerline to each shoulder. For larger tires, locate holes at 50 mm increments. 5.1.1.4 Continuous rib design tires require holes in the center of each rib. Ribs wider than 76 mm will require additional holes 25 mm either side of the center, but not closer than 12.5 mm from the rib edge. 5.1.1
14、.5 Mark off increments as described in 5.1.1.3 and 5.1.1.4 across the crown of the tire. FIGURE 1 - THERMOCOUPLE NEEDLE AND HOLDER SAE J1015 Revised JUL2012 Page 4 of 8 5.1.2 Drill Hole Depth Determination 5.1.2.1 Depth of the drilled holes should be such that the bottom of the hole is within 2.5 mm
15、 of the top of the highest reinforcement cord, but not into or through this cord. 5.1.2.2 If the carcass thickness is known, measure the total tire thickness at the location determined in 5.1.1.3 and subtract the known carcass thickness from this measurement; the drill depth should be 2.5 mm less th
16、an the difference.5.1.2.3 If the total thickness is not known, then the drill depth can be determined by drilling test core holes. 5.1.2.3.1 Make core drillings not to exceed 6 mm diameter at the prescribed intervals (see 5.1.1.3 and 5.1.1.4) from the centerline to both shoulders on a tread element
17、immediately adjacent to the intended probe location. On rib design tires, the cored hole shall not be within 50 mm of the drill location. Cores should be drilled normal or perpendicular to the tread surface. Core drilling depths should not extend beyond breaker or belt plies into body plies or ply.
18、In the case of steel cord construction tires, core drilling should not go deeper than when initial contact with the steel cord belt/breaker plies occurs. 5.1.2.3.2 Measure the reinforcement (carcass material) thickness on the plugs removed from the cored holes and subtract from the depth of the core
19、d hole. This measurement less 2.5 mm determines the probe depth for that location.5.2 Inflation New tires shall be inflated for 24 h prior to the first test. Test tires should be inflated to the TRA Yearbook pressure for the subject ply rating or load range. 5.3 Break-In New test tires are to be run
20、 for between 130 and 160 km at a load and speed combination estimated to produce an actual stable temperature within the limits listed as follows: 5.3.1 Bias ply (textile) tires, 87 to 107 C. 5.3.2 Radial ply (steel cord) tires, 71 to 93 C. 6. TEST PROCEDURE 6.1 Test Conditions 6.1.1 Selecting Test
21、Load The test load is determined by selecting a load of 85% of the TRA yearbook 50 km/h capacity table for both test tires. The load shall be measured for each tire within 2% of the selected test load. This load shall be used throughout the test. 6.1.2 Setting of Test Inflation Pressures Immediately
