BS EN 16476:2014

This standard BS EN 16476:2014 Liquid petroleum products. Determination of Sodium, Potassium, Calcium, Phosphorus, Copper and Zinc contents in diesel fuel. Method via Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) is classified in these ICS categories:

• 75.160.20 Liquid fuels

This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP OES) method for the determination of sodium, potassium, calcium, phosphorus, copper and zinc concentrations of diesel fuels, including those containing up to 30 % (V/V) fatty acid methyl ester (FAME), in the range detailed in Table 1. These six elements are considered as the most essential ash forming elements.

Table 1 Application ranges for ash forming elements

Element	Range mg/kg
Sodium	1,2 to 2,5
Potassium	0,9 to 2,5
Calcium	0,3 to 2,5
Phosphorus	0,9 to 2,5
Copper	0,2 to 2,5
Zinc	0,2 to 2,5

NOTE For the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction, φ.
