    Significance and Use

    5.1 These test methods shall be used where precise dimensions are necessary for the calculation of properties expressed in physical units. They are not intended to replace practical thickness measurements based on commercial portable tools, nor is it implied that thickness measurements made by the procedures will agree exactly.

    5.2 Examples of machinist’s micrometers, including pictures with descriptions of their components and pictures of the micrometers used can be located in Practice A1073/A1073M. However, make sure the micrometer, the calibration of it, and the use of it adheres to the requirements of this standard.
