TURBOCHARGER GAS STAND TEST CODE
Foreword—This Reaffirmed Document has been changed only to reflect the new SAE Technical Standards Board
Format.
1. Scope—The test procedures outlined in this SAE mended Practice are applicable to single rotor
turbochargers having either fixed- or variable-geometry with the following caveat:
At this stage in the development of variable-geometry (VG) turbochargers, it would be impractical to generate
a detailed practice to cover all types of VG turbochargers which may evolve. However, there is a requirement
to quote performance data within a stipulated degree of accuracy and to prehensive performance
information. This will form a basis for this document where further refinements may be added as experience
and necessity dictate.
Purpose—The purpose of this document is to provide a mended laboratory test procedure and
presentation format for establishing ponent performance for a turbocharger. It is intended that this test
procedure be used to determine pressor and turbine performance characteristics. The
resulting data are intended for use in ponent performance assessment and development and
for engine/turbocharger matching.
