  flavor: oiml
  scope: This Recommendation applies to « gauge blocks of rectangular section », which
    are measures of length in the form of rectangular plates or parallelepipedal rectangular
    blocks comprising two opposing, flat, mutually parallel, faces, called measuring
    faces, whose surface quality is such that they have the property of wringing to
    the corresponding faces of other gauges or plane datum surfaces. It lays down
    the principal technical specifications relating to their intended use, their manufacture,
    their qualities, their inspection.
