檢測的定義(Inspecting):
     依據設計圖面上之要求(例如:長度或是形狀的要求)，來測試工件是否符合實際使用上的需求標準。
Inspecting
Determining whether a test object complies with the specified requirements (e.g. as regards dimensions and form).

量測的定義(Measuring):
     被測物與量測標準值，經由比對量測過程之後所得到的一個數值(例如:長度或是材質的量測)。
Measuring
Obtaining a value (e.g. of a length) measured by comparison against a measurement standard (e.g. material measure).

校正的定義(Calibrating):
     經由實際的量測過程來確立所使用量測儀器的實際誤差值，校正結果之數值通常以證明書格式表列出來，並可作為爾後量測結果數值調整參考依據。
Calibrating
Establishing the actual deviation from the desired value of a measuring instrument. This is usually done through measurement operations. The result of a calibration is documented in the form of a calibration certificate and can be used later on for adjustment purposes, for instance.
