EN 7 is the older European Standard for determining the ash content of petroleum products by controlled ignition and high-temperature ashing. To match this to your program, talk with our team.
What EN 7 Covers
It quantifies the incombustible residue in petroleum products by ashing and weighing, an indicator of contaminant or additive content.
How the Test Is Run
A measured petroleum sample is ignited and ashed at high temperature, and the remaining residue is weighed to give the ash content.
Why It Matters
Ash content indicates contaminants that affect product quality; a controlled furnace and accurate mass measurement are essential.
