radial distance between the smallest circumscribed sphere and the greatest inscribed sphere, with their centres common to the least squares sphere centre
NOTE This definition supersedes ISO 5593:1997, 05.06.03.
surface irregularities of random or periodical deviation from the ideal spherical form
NOTE 1 Waviness can be evaluated as velocity amplitude by default.
NOTE 2 In practice, the waviness components are separated from the real surface by a waviness analyser (filters).
surface irregularities with relatively small spacings, which usually include irregularities resulting from the method of manufacture being used and/or other influences
NOTE These irregularities are considered within the limits that are conventionally defined, e.g., within the limits of the sampling length.
element, irregularity or group of elements and irregularities of the real surface, unintentionally or accidentally caused during manufacture, storage, handling or use of the surface
NOTE 1 These types of element or irregularity differ considerably from those constituting the surface roughness and are not considered during the measurement of the surface roughness.
NOTE 2 The limits for surface defects are not specified in this part of ISO 3290.
definite quantity of balls manufactured under conditions presumed uniform and which is considered as an entity[ISO 5593:1997, 05.04.05]
amount by which the mean diameter of ball lot should differ from the nominal ball diameter, this amount being one of an established series [ISO 5593:1997, 05.04.09]
NOTE 1 Each ball gauge is a whole multiple of the ball gauge interval established for the ball grade in question.
NOTE 2 A ball gauge, in combination with the ball grade and nominal diameter, is considered as the most exact ball size specification to be used by a customer for ordering purposes.ABMA 3290-2 pdf free download.
