一、修订背景JJG910-1996《摩托车轮偏检测仪》检定规程(以下简称“旧规程”)自1996年颁布实施以来已有17年。随着摩托车通用技术条件的修订,摩托车前后轮中心平面允许偏差已经由±7mm调整为±10mm。同时在检定实践中也发现了一些情况,因此有必要对旧规程中的一些计量性能要求和检定方法进行修订。起草组依据科学性和可操作性的原则,充分考虑现行相关技术标准和其他要求,在广泛征求各计量技术机构、科研院所、生产企业意见和试验验证的基础
First, the revised background JJG910-1996 “motorcycle wheel bias detector” verification procedures (hereinafter referred to as “old procedures ”) has been implemented since 1996, 17 years. With the revision of general motorcycle technical conditions, the allowable deviation of the front and rear wheel center plane of the motorcycle has been adjusted from ± 7mm to ± 10mm. In the meantime, some cases have also been found in the verification practice. Therefore, it is necessary to revise some metrological performance requirements and verification methods in the old procedures. Based on scientific and operational principles, the drafting group fully solves the existing relevant technical standards and other requirements and extensively solicits the opinions of all measuring technical institutes, research institutes and manufacturing enterprises as well as the basis of experimental verification
