范围
本规程适用于中准确度级和普通准确度级的数字指示轨道衡 (以下简称轨道衡)的
首次检定、后续检定和使用中检验。
机电结合数字指示轨道衡的非自行指示装置按JJG 142-2002《非自行指示轨道衡》
检定规程进行检定，数字指示装置按本规程进行检定。
2 引用文献
本规程引用下列文献:
JJG 555-1996《非自动秤通用检定规程》
JJG 567-1989《检衡车》
GB 2887-2000《计算站场地技术条件》
使用本轨程时应注意使用上述引用文献的现行有效版本。
3 术语和 计f单位
JJG 555-1996《非自动秤通用检定规程》的部分术语适用于本规程，为便于计量检
定，特引用其计量管理中的部分术语。
3.1 检定
查明和确认轨道衡是否符合法定要求的程序，它包括检查、加标记和出具检定证
书 。
3.2 首次检定
对未曾检定过的新轨道衡进行的一种检定。首次检定包括:
a)新制造、新安装轨道衡的检定;
b)新进口轨道衡的检定。
3.3 后续检定
轨道衡首次检定后的任何一种检定:
a)强制性周期检定;
b)修理后检定;
c)周期检定有效期内的检定，不论它是由用户提出请求，或由于某种原因使有效
期内的封印失效而进行的检定。
