Age the specimens under the following conditions:7.1.2.1.1. 3个内胎气门嘴在180oC 3oC 放15分钟min 30 秒 Three inner-tube valves at 180oC 3oC for 15 min 30 s.7.1.2.1.2. 3个轮辋气门嘴在100oC 3oC 放 4 小时 5分钟 Three rim valves at 100oC 3oC for 4 h 5 min.7.1.2.2. 将气门嘴从高温箱移走，在测试前冷却至少12小时。把支架拧上气门嘴的出口，用收聚钳和圆边钳将橡胶从气门嘴拆走，要不损坏橡胶覆盖的金属嘴杆（见图1，2和3）Remove the valves from the furnace and let them cool for at least 12 hours before the test. Screw the maneral? onto the valve outlet and using the pinching pliers with rounded edge remove the rubber from the valves without damaging the metal covered by the rubber (see figures 1, 2 and 3).7.1.3. 结果描述：确定支持的数量并以mm2 陈述没有被橡胶覆盖的金属区域的结果，用以下计算。Statement of results: quantify the adhesion and state the result in mm2 of metallic area not covered by the rubber, using the following calculation:Quantify the adhesion and state the result in mm2 of the metallic area not covered by the rubber, realizing the following for the calculation:7.1.3.1. 在测试区域贴上胶带 ，该区域按照面积单位有一个恒定的重量 Stick an adhesive tape onto the test area having a constant weight per area unit.7.1.3.2. 在没有任何金属/橡胶的区域上贴的胶条上做一个记号（在该区域完全分离橡胶与金属，观察粘附的金属或接合剂。Mark with a tip on the tape the area without any metal/rubber adhesion (in this area the rubber is completely detached from the metal and observe the adhered metal or cement).7.1.3.3 将胶带从测试区域移走，切下做标记的地方。Remove the tape from the test area and cut off the marked areas.7.1.3.4. 称重修整好的区域，以毫克为单位，用“A”标明该值Weigh the trimmed areas in mg, record this value as A.7.1.3.5. 称重40 mm2 贴有胶带的区域，以毫克为单位。用“B”标明所获得的重量的值。做以下计算：粘合剂*（橡胶-金属）=（A/B）*(40 mm2)注意：所获得的该公式的结果为mm2 ，而且粘合剂与一个区域有关。Weigh in mg a 40 mm2 area of the adhesive tape used. Record this value as B with the obtained weights. Do the following calculations:Adhesion (rubber-metal) = (A/B) * (40 mm2)Note: The result of this equation in obtained in mm2 and the adhesion is related to one area.7.2. 轮辋气门嘴拆卸力Rim valve disassembly effort (force) 该测试用于橡胶浇铸的，装在无内胎轮胎轮辋上的气门嘴。目的是确定安装在轮辋上的气门嘴在被毁坏和金属没有任何裂缝前能承受的力，确保不出现这些情况不会发生。This test is made to valves with molded rubber adhered to it, mounted on the rim used for tubeless tires in order to determine the force which the valve to be assembled onto the rim can withstand before being destroyed and without any cracks in the metallic part, making sure that this does not happen.7.2.1. 设备Equipmenta) 带有无线的，中心孔的金属板，直径11.4mm，或其它的能够锚定气门嘴底座的直径，厚3.2mm。Metal plate with wireless, central hole, with an 11.4 mm diameter, or other metal plate with a 15.7 mm diameter, or the diameter able to anchor the valve base and 3.2 mm thick.b) 气门嘴支架Maneral(?) clamp for the valve.c) 金属板夹具Clamp for the metal plate.d) 肥皂水Soap diluted in water.e) 最小10 kN 容量的气体压力计Tensimeter with minimum 10 kN capacity.Figure 1 Adhesion test of valves for rimFigure 2 Adhesion test of valve for innertubesFigure 3 Adhesion test of valve for rim7.2.2. 步骤Procedure7.2.2.1. 把卡扣气门嘴放在金属板的空中，以便用肥皂水的操作，要考虑以下问题：Place the valve with the molded rubber adhered to it in the orifice of the metal plate, facilitating the operation with the diluted soap, taking the following into consideration:7.2.2.1.1. 用于TR-412; TR-413; TR-414; TR-418; TR-423; 600 HP 和 602 HP或类似气门嘴测试的带孔的板直径为11.4mm。Plate with orifice with 11.4 mm diameter for valves TR-412; TR-413; TR-414; TR-418; TR-423; 600 HP and 602 HP or equivalent.7.2.2.1.2. 用于TR-415 and TR-425 or equivalent或类似气门嘴测试的带孔的板直径为15.7mm，或者适合被测气门嘴的直径。 Plate with orifice with 15.7 mm diameter for valves TR-415 and TR-425 or equivalent or with a diameter adapted to the valve to be tested.7.2.2.2.把气门嘴放在金属盘夹具中，在气体压力计中装上装备设备，把支架拧上轮辋气门嘴。以 500 mm/分钟 50 mm/分钟的速度拧紧气门嘴.当气门嘴从金属板的孔脱落时所获得气体压力计的值就是将气门嘴从轮辋孔拆卸下来所需要的力的值。Place the valve in the clamp for the metal plate, install the assembled device in the tensimeter, screwing the mineral? to the valve for the rim; tighten the valve at a speed of 500 mm/min 50 mm/min. The tensimeter value obtained when the valve breaks off or exits the orifice of the metal plate is the magnitude of the effort required to disassemble the valve from
