Derwent Classification System: Nucleonics, Explosives and Protection

All aspects of the nuclear industry, chemical aspects of fire fighting, explosives and warfare agents.

Approximate IPCs are given in brackets.

K01 Fire fighting, fire-extinguishing compositions - excluding fire engines, sprinkler systems, hose reels and protective clothing (A62D with K2).
K02 Protection against chemical warfare breathing apparatus - chemical aspects only (A62D with K1).
K03 Explosive charges; ammunition, fuses, blasting including only complete devices, except missile systems (F42).
K04 Explosives, matches - including detonators, chemical lighters, pyrophoric compositions, fire works, distress signals, chemical lasers, smoke generation, gas attack compositions, generation of gas for blasting or propulsion, but only their chemical aspects (C06).
K05 Nuclear reactors and simulators - including reactor processes, components and accessories, but excluding power plant (G21B, C).
K06 Nuclear power plant - including reprocessing used nuclear fuel (G21D).
K07 Health physics - including radiation protection (other than against sunlight), monitoring devices, decontamination, radioactive waste disposal and protective clothing (G21F).
K08 Nucleonics; X-ray techniques - including conversion of chemical elements, nuclear explosives and plasma techniques other than electron beam or plasma welding methods and apparatus and X- ray films (G01T, G21G, H, J, K, H05G, H).
