The most fundamental methods of measurement will be described here, but other equipment is available if a greater degree of accuracy is desired.
This SAE Standard defines the normal dimensions, dimensioning practice, tolerances, specialized measurement techniques, and glossary of terms for bearing inserts commonly used in reciprocating machinery. The standard sizes cover a range which permits a designer to employ, in proper proportion, the durability and lubrication requirements of each application, while utilizing the forming and machining practices common in manufacture of sleeve type half bearings. Not included are considerations of hydrodynamic lubrication analysis or mechanical stress factors of associated machine structural parts which determine the nominal sizes to be used, selection of bearing material as related to load carrying capacity, and economics of manufacture. For information concerning materials, see SAE J459 and SAE J460. These suggested sizes provide guidelines which may result in minimal costs of tooling but do not necessarily represent items which can be ordered from stock.

While this report does not include a discussion of all of the available data defining human response or address all body areas, for those areas addressed it does utilize references generally judged by those in the field to be practical and meaningful guidelines for the development of human surrogates. This report is intended to be a “living” document that will be updated periodically. A number of problems need to be addressed in defining human impact response characteristics. There is the problem of human response variability from subject to subject in volunteer tests. There is the problem of extrapolating such volunteer data which are obtained at low impact severities to higher impact severities using human cadaver response data obtained at injurious levels of impacts. Live animal experiments have been conducted over the years in an attempt to define human impact response and tolerance. The problem with using animal response data is the lack of geometric scaling techniques needed to
