Thus 100 litres of 96% alcohol would contain only 96 litres of \u201cactive ingredient\u201d or 96 litres of absolute alcohol. Hence the unit \u201clitres absolute alcohol\u201d or \u201claa\u201d is in universal use in the industry. The larger volume unit, \u201ckilolitres absolute alcohol\u201d or \u201cklaa\u201d is self explanatory. Often the \u201caa\u201d is omitted, but is understood. Care has to be exercised, as the logistics industry refer to litres meaning \u201cbulk litres\u201d, i.e., an actual volume measurement.\n\n\n\n\n<p>Lorem Ipsum has been the industry&#8217;s standard dummy text ever since the 1500s.<\/p>\n\n\n\n<p [object NamedNodeMap]>Undenatured or pure alcohol is subject to excise duty, but this duty is <br>applicable only to the alcohol content. Determination of the\u00a0<strong>alcohol strength<\/strong>\u00a0is<br> thus critical. This is done by measuring the density or specific <br>gravity by means of a\u00a0densitometer (e.g., Paarman) or a hydrometer\u00a0and <br>reading off the\u00a0<u>a<\/u>lcohol\u00a0percentage strength\u00a0<u>b<\/u>y\u00a0<u>v<\/u>olume<br> (abv)\u00a0from the instrument or from tables, respectively.

High strength <br>alcohol is flammable. A test whether alcohol was watered down was to set<br> fire to a small quantity of gunpowder that had been damped with the <br>spirit. If it burned then that was \u201cproof\u201d that this was good (strength)<br> alcohol. The strength at which the damped\u00a0gunpowder will\u00a0just burn is <br>57.15 % and in the UK this was taken as 100 degrees proof. It follows <br>that 100 % ethanol\u00a0would be referred to as \u00a0175 degrees proof or 75 <br>degrees overproof.
