IP 429: Liquid petroleum products - Petrol - Determination of the benzene content by infrared spectrometry

Overview:

This European Standard specifies an infrared spectrometric method for the determination of benzene content in petrol in the range 0,1% (V/V)
to 20% (V/V). The presence of cyclopentadiene in the sample will interfere with the benzene determination when it exceeds 5% (V/V).
Contents of ethanol less than 10% (V/V) and toluene less than 25% (V/V) do not interfere with the benzene determination.

WARNING: The use of this European Standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
