sample;
 (7) the material controlled in paragraph (e)(4) of this category has not been treated to reach the 75% transmission level referenced in (m)(6) of this category;
 (8) metal laminate armours are two or more layers of metallic materials which are mechanically or adhesively bonded together to form an armour system;
 (9) Em is the line‑of‑sight target mass effectiveness ratio and provides a measure of the tested armour's performance to that of rolled homogenous armour, where Em is defined as follows:

           where:

           ρRHA is density of RHA, (7.85 g/cm3).

           Po is Baseline Penetration of RHA, (mm).

           Pr is Residual Line of Sight Penetration, either positive or negative (mm RHA equivalent).

           ADTARGET is Line‑of‑Sight Areal Density of Target (kg/m2).

  If witness plate is penetrated, Pr is the distance from the projectile to the front edge of the witness plate. If not penetrated, Pr is negative and is the distance from the back edge of the target to the projectile.
