Relationship between large subject matter areas

This subclass does not cover chemical compounds or their preparation as such, which subject matter is covered by classes C01 (inorganic chemistry), C07 (organic chemistry) and C08 (organic macromolecular compounds).

References relevant to classification in this subclass

Glossary of terms
In this subclass/group, the following terms (or expressions) are used with the meaning indicated:
Pyrophoric
Pyrophoric (Greek, meaning fire-bearing) materials are finely divided chemical substances, mostly metals, which at room temperature vehemently react with the oxygen contained in air. The energy released in this oxidation process is sufficient to make substances glow or blaze. Therefore a pyrophoric material can spontaneously ignite in air.
Fuses, e.g. fuse cords
Fuse igniting means; Fuse connectors
Definition statement
This subclass/group covers:

Compositions of delay mixtures

Informative references
Attention is drawn to the following places, which may be of interest for search:
Blasting methods or apparatus, e.g. loading or tamping Arrangements for ignition
Ignition systems for methods or apparatus for obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells
Non-electric detonators; Blasting caps; Primers
