SAE J1157_197608

The detailed test procedures outlined in this recommended practice consist of two general types of tests. These tests are of the bench type and a full scale engine type test which exposes the smokemeter to the environment (exhaust gases) that the meter ultimately must perform in if it is to be of practical use. The bench type tests consist of two general types. The first series of bench tests are used to assess the basic optical and electrical characteristics of the instrument. The second series of bench tests are used to evaluate the effect of a simulated operating environment (temperature light and vibration) on the smokemeter. Finally performance limits for the various types of smokemeters and for various smoke concentrations are established based on the bench and engine performance tests outlined above.
