This SAE Recommended Practice applies to a production
dynamometer test procedure which can be used to measure the smoke
and gaseous emission characteristics of vehicular diesel engines.
This procedure describes the smoke emission test method, smoke test
cycle, gaseous emission test method, steady-state gaseous emission
test cycle, equipment, instrumentation, calibration, data analysis,
and correlation of results for comparison of production engine
emission performance to the requirements of current or past Federal
regulations.

Variations in engines, instrumentation, and test equipment may
require modifications to these procedures or data reduction
methods. The acceptability of this procedure is dependent upon
documented statistical data appropriate to correlate all tests,
data reduction techniques, and special instrumentation to the
required Federal tests.

When using the audit test procedure to assess the emissions
performance of production engines, considerations should be given
to expected emissions deterioration factors and quality control
limits should be adjusted accordingly.

This document is intended as a guide for the measurement and
assessment of transient smoke and steady-state gaseous emissions
from heavy duty vehicular diesel engines only using a shortened
engine dynamometer cycle which may be applicable to production line
or production quality audit conditions. Key elements of the
procedure closely resemble key elements of the Federal Test
Procedures used for regulatory approval by the United States
Government.
