一、规范制定的目的及背景附着系数测试仪是用于测量轮胎与各种机动车用检验台的滚筒(平板)表面或检测路面的附着系数的计量仪器。在许多相关国家标准和国家计量检定规程中,都明确提出了“附着系数”的技术要求,很清楚地说明了“附着系数”的重要性,因此对其进行量值溯源很重要。为了解决量值溯源的问题,JJF1551-2015《附着系数测试仪校准规范》于2015年12月7日由国家质检总局发布,并自2016年3月7日起实施,其中规定了附着系数测试仪的计量特性、校准方法与校准项目。
First, the purpose of setting norms and background Cohesion coefficient tester is used to measure the tire and a variety of motor vehicles with a test-bed drum (flat) surface or measuring the adhesion coefficient of the road measuring instruments. In many relevant national standards and national metrological verification procedures, the technical requirements of “adhesion coefficient” are clearly stated, and the importance of “adhesion coefficient ” is clearly shown. Therefore, it is very important . JJF1551-2015 “Coefficient of Correction Coefficient Tester Calibration Standards” was released by AQSIQ on December 7, 2015 and implemented since March 7, 2016, which stipulates the adhesion coefficient test Metrology instrument characteristics, calibration methods and calibration items.
