What it means
The test checks that the line's ram:SpecifiedTradeProduct, representing item information (BG-31), has no direct ram:AreaDensityMeasure child. Area density is mass per unit area, such as grams per square metre.
Why it matters
EN 16931 does not map this separate area density element. You can retain relevant product specifications in the supported description or attribute fields.
How to fix it
Remove ram:AreaDensityMeasure from the exported product details. If the figure matters, record both its value and unit in an item attribute (BG-32), such as Weight per square metre, or in ram:Description (BT-154). Export the revised file and check it again.
