< div class=" SectionLevel3" > < p class=" subsec2 cdone2" > < span class=" Head4 cdone" > 1.1.1< / span> & #x00a0 Petroleum distillates that are substantially free of material lighter than isobutane and that have 90& #8201 % distillation points (by Test Method < span class=" Body-link1 cdone" > D86< / span> ) under 327& #8201 & #x00b0 C (626& #8201 & #x00b0 F). This test method is generally applicable to gasoline (including leaded, unleaded, and oxygenated fuels), kerosine, and distillates in the gas oil range that fall in the following limits:

This test method has been found suitable for such materials as commercial propylene trimer and tetramer, butene dimer, and mixed nonenes, octenes, and heptenes. This test method is not satisfactory for normal alpha-olefins.

< / div> < / div> < / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.2< / span> & #x00a0 The magnitude of the bromine number is an indication of the quantity of bromine-reactive constituents, not an identification of constituents therefore, its application as a measure of olefinic unsaturation should not be undertaken without the study given in < span class=" Body-link1 cdone" > Annex A1< / span> .

< / div> < div class=" SectionLevel2" > < p class=" subsec1 cdone2" > < span class=" Head3 cdone" > 1.3< / span> & #x00a0 For petroleum hydrocarbon mixtures of bromine number less than 1.0, a more precise measure for bromine-reactive constituents can be obtained by using Test Method < span class=" Body-link1 cdone" > D2710< / span> . If the bromine number is less than 0.5, then Test Method < span class=" Body-link1 cdone" > D2710< / span> or the comparable bromine index methods for industrial aromatic hydrocarbons, Test Methods < span class=" Body-link1 cdone" > D1492< / span> or < span class=" Body-link1 cdone" > D5776< / span> must be used in accordance with their respective scopes. The practice of using a factor of 1000 to convert bromine number to bromine index is not applicable for these lower values of bromine number.
