Standard Test Method for Bromine Index of Aromatic Hydrocarbons by Coulometric Titration
|Publication Date:||1 July 2008|
This test method covers the determination of the amount of bromine-reactive material in aromatic hydrocarbons. It is usually applied to materials having bromine indexes below 500.
NOTE 1-Other test methods for determining bromine-reactive material are Test Methods D1159, D1491, D2710, and D5776.
This test method has been found applicable to aromatic hydrocarbons containing no more than trace amounts of olefins and that are substantially free from material lighter than isobutane and have a distillation end point under 288°C.
The following applies to all specified limits in this test method: For purposes of determining conformance with this test method, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Warning-Mercury has been designated by EPA and
many state agencies as a hazardous material that can cause central
nervous system, kidney, and liver damage. Mercury, or its vapor,
may be hazardous to health and corrosive to materials. Caution
should be taken when handling mercury and mercury-containing
products. See the applicable product Material Safety Data Sheet
(MSDS) for details and EPA's website
