(d) Materials, as follows:
(1) ablative materials fabricated or semi‑fabricated from advanced composites (for example, silica, graphite, carbon, carbon/carbon, and boron filaments) specially designed for the articles in Category IV or XV (MT if usable for nozzles, re‑entry vehicles, nose tips or nozzle flaps usable in rockets, space launch vehicles (SLVs) or missiles capable of achieving a range greater than or equal to 300 km);
(2) carbon/carbon billets and preforms that are reinforced with continuous unidirectional fibres, tows, tapes, or woven cloths in three or more dimensional planes (MT if usable for rocket, SLV or missile systems and usable in rockets, SLVs or missiles capable of achieving a range greater than or equal to 300 km).
Note 1: “Range” is the maximum distance that the specified rocket system is capable of travelling in the mode of stable flight as measured by the projection of its trajectory over the surface of the Earth. The maximum capability based on the design characteristics of the system, when fully loaded with fuel or propellant, will be taken into consideration in determining range. The range for rocket systems will be determined independently of any external factors such as operational restrictions, limitations imposed by telemetry, data links, or other external constraints. For rocket systems, the range will be determined using the trajectory that maximises range, assuming International Civil Aviation Organization (ICAO) standard atmosphere with zero wind.
Note 2: This paragraph does not control carbon/carbon billets and preforms where reinforcement in the third dimension is limited to interlocking of adjacent layers only.

(m) The following interpretations explain and amplify terms used in this category and elsewhere in this list:
(1) composite armour is defined as having more than one layer of different materials or a matrix;
(2) spaced armours are metallic or non‑metallic armours that incorporate an air space or obliquity or discontinuous material path effects as part of the defeat mechanism;
(3) reactive armour employs explosives, propellants, or other materials between plates for the purpose of enhancing plate motion during a ballistic event or otherwise defeating the penetrator;
(4) electromagnetic armour (EMA) employs electricity to defeat threats such as shaped charges;
(5) materials used in composite armour could include layers of metals, plastics, elastomers, fibres, glass, ceramics, ceramic‑glass reinforced plastic laminates, encapsulated ceramics in a metallic or non‑metallic matrix, functionally gradient ceramic‑metal materials, or ceramic balls in a cast metal matrix;
(6) for this category, a material is considered transparent if it allows 75% or greater transmission of light, corrected for index of refraction, in the visible spectrum through a 1 mm thick nominal 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:
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.
