This document specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. This document is applicable to stabilized crude oils and for the boiling range distribution and the recovery up to and including n-nonane. A stabilized crude oil is defined as having a Reid Vapour Pressure equivalent to or less than 82,7 kPa as determined by IP 481 [3].

Annex C specifies an algorithm for merging the boiling point distribution results obtained using this method with the results obtained with EN 15199-3 . This will result in a boiling range distribution and recovery up to C120.

NOTE 1

There is no specific precision statement for the combined results obtained after merging the results of EN 15199?3 and EN 15199?4 . For the precision of the boiling range distribution up to n-nonane, the precision statement of EN 15199?4 applies. For the precision of the boiling range distribution from n-nonane through C120, the precision of EN 15199?3 applies.

NOTE 2

For the purposes of this document, the terms “% ( m/ m)” and “% ( V/ V)” are used to represent respectively the mass fraction, ?, and the volume fraction, ?.

The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to take appropriate measures to ensure safety and health of personnel prior to application of the document and fulfil statutory and regulatory requirements for this purpose.
