(Test Method)Standard Test Method for Smoke Density in Flue Gases from Burning Distillate Fuels
Standard Test Method for Smoke Density in Flue Gases from Burning Distillate Fuels
SIGNIFICANCE AND USE
This test method provides a means of controlling smoke production in home heating equipment to an acceptable level. Excessive smoke density adversely affects efficiency by heat-exchanger fouling.
The range of smoke densities covered by this test method is that which has been found particularly pertinent to home-heating application. It is more sensitive to small amounts of smoke than several other smoke tests as indicated in the following comparison:
SCOPE
1.1 This test method covers the evaluation of smoke density in the flue gases from burning distillate fuels. It is intended primarily for use with home heating equipment burning kerosine or heating oils. It can be used in the laboratory or in the field to compare fuels for clean burning or to compare heating equipment.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1 Arbitrary and relative units are also used.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
