platforms or equipment through shaping, active, or passive techniques.
 (j) Equipment, materials, coatings, and treatments not elsewhere specified, as follows:
 (1) specially treated or formulated dyes, coatings, and fabrics used in the design, manufacture, or production of personnel protective clothing, equipment, or face paints designed to protect against or reduce detection by radar, infrared, or other sensors at wavelengths greater than 900 nanometres (see Category X(a)(2));
 (2) equipment, materials, coatings, and treatments that are specially designed to modify the electro‑optical, radiofrequency, infrared, electric, laser, magnetic, electromagnetic, acoustic, electro‑static, or wake signatures of defence articles through control of absorption, reflection, or emission to reduce detectability or observability (MT for applications usable for rockets, SLVs, missiles, drones, or UAVs capable of achieving a range greater than or equal to 300 km, and their subsystems. See note 1 to paragraph (d)).
 (k) Tooling and equipment, as follows.
 (1) tooling and equipment specially designed for production of low observable (LO) components;
 (2) portable platform signature field repair validation equipment (for example, portable optical interrogator that validates integrity of a repair to a signature reduction structure), and their subsystems. See note 1 to paragraph (d)).
 (l) Technical data and defence services directly related to the defence articles described in paragraphs (a) to (h), (j) and (k) and defence services directly related to the defence articles described in this category. (MT for technical data and defence services related to articles designated as such).
 (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
