Abstract
A clear definition of the measurand is an essential precondition for measuring. When verifying conformity to ISO GPS tolerances (verification), the measurand is often unclear, particularly for geometrical tolerances. The tolerance zone is a portion of space whereas the measurand is a scalar quantity, and many such quantities may be derived from the same portion of space. We propose a unified derivation of the measurand in ISO GPS verification matching the designer's intent. Different types of tolerances are considered, from the easiest to the least obvious as to the derivation of the measurand.
明确定义测量对象是测量的基本前提。在验证是否符合 ISO GPS 公差（验证）时，测量值往往不明确，尤其是几何公差。公差带是空间的一部分，而测量值是一个标量，许多这样的量可以从空间的同一部分推导出来。我们建议在 ISO GPS 验证中对测量值进行统一推导，以符合设计者的意图。我们考虑了不同类型的公差，从最简单到最不明显的测量值推导。
