· Upper limit (additives / contaminants / pesticide residues and other residue limits): measured mean ≤ limit is acceptable; tick U to use mean+U ≤ limit (more conservative, accounting for measurement uncertainty).

· Lower limit (content / minimum requirement for beneficial components): measured mean ≥ limit is acceptable; tick U to use mean−U ≥ limit.

· U is the expanded uncertainty (k=2).
