Materials specially designed for use as absorbers of electromagnetic waves, or intrinsically conductive polymers, as follows: (a) Intrinsically conductive polymeric materials with a ‘bulk electrical conductivity’ exceeding 10 000 S/m (Siemens per metre) or a ‘sheet (surface) resistivity’ of less than 100 ohms/square, based on any of the following polymers: 1. Polyaniline; 2. Polypyrrole; 3. Polythiophene; 4. Poly phenylene-vinylene; or 5. Poly thienylene-vinylene. Technical note : ‘Bulk electrical conductivity’ and ‘sheet (surface) resistivity’ should be determined using ASTM D-257 or national equivalents.

EU Regulation No 267/2012

Materials for reduced observables such as radar reflectivity, ultraviolet/infrared signatures and acoustic signatures (i.e. stealth technology), for applications usable for the systems specified in 1.A. or 19.A. or the subsystems specified in 2.A. Notes: 1. 17.C.1. includes structural materials and coatings (including paints), specially designed for reduced or tailored reflectivity or emissivity in the microwave, infrared or ultraviolet spectra. 2. 17.C.1. does not control coatings (including paints) when specially used for thermal control of satellites.
