ash content
non-combustible residue of a lubricating oil or fuel determined with test methods ASTM D428 and D874 (sulfated ash) Lubricating oil detergent additives contain metallic derivatives such as barium, calcium and magnesium sulfonates that are a common source of ash
The solid residue remaining after a substance has been incinerated or heated to a temperature sufficient to drive off all combustible or volatile substances
the residue of a scoured wool subsample after it has been subjected to charring followed by heating to 800oC It is expressed as a percentage of the subsample mass and is taken to represent the dirt (sand and soil) not removed during the scouring of the greasy subsample
The percent by weight of residue left after combustion of an oil sample (ASTM Method D 482)
Proportion of the solid residue remaining after a reinforcing substance has been incinerated (charred or intensely heated)
The residue of paper after incineration to a constant weight, is expressed as a percentage of the sample's original weight and represents the mineral filler content, e g , clay, titanium dioxide
The residue left after complete combustion of paper at high temperature It is generally expressed as percent of original test sample and represents filler content in the paper
Ratio of mass of residue after combustion to mass of sample (pulp/paper) before combustion
non-combustible residue of a lubricating oil (also fuels) determined in accordance with ASTM D582 - also D874 (sulphated ash) Since some detergents are metallic salts or compounds, the percentage of ash has been considered to have a relationship to detergency Interpretations can be grossly distorted, however, for the following reasons: 1 Detergency depends on the properties of the base oil as well as on the additive Some combinations of base oil and additive are much more effective than others 2 Detergents vary considerably in their potency, and some leave more ash than others Organic detergents have been developed, in fact, that leave no ash at all 3 Some of the ash may be contributed by additives other than detergents 4 There appears to be a limit to the effective concentration of detergent Nothing is gained by exceeding this limit, and a superabundance of detergent may actually reduce cleanliness
The % of ash resulting from the complete combustion of a specific weight of cellulosic material, such as wood pulp and paper, in which all the carbon, combustibles and volatile compounds are removed It is an indication of the amount of mineral salts, inorganic matter, filler, coating, pigmentation and chemical additive contents in paper sheet
