Aldehyde
Aldehydes are chemical compounds containing a terminal carbonyl group (or more exactly
an aldehyde group, CHO) as the functional group. The series of aldehydes derived from the
alkanes form the homogenous series of alkanals.
Aliphatic hydrocarbons
Aliphatic hydrocarbons (Greek: aleiphar, fatty) are organic hydrocarbon chains. Aliphatic
compounds are "acyclic or cyclic, saturated or unsaturated carbon compounds except
aromatic compounds". The simplest group of aliphatic hydrocarbons are the alkanes. Like all
pure hydrocarbons, aliphatic hydrocarbons are nonpolar, lipophilic compounds.
American wire gauge (AWG)
American Wire Gauge is a specification for wire diameters, and mainly used in North
America. It identifies electric cables made of stranded or solid wire and is used in electrical
engineering to identify the cross-section of conductors.
Analog
Continuous representation of a variable, e.g. voltage, using a scale, in contrast to "Digital".
Aromatic compounds
Aromatic compounds, or also arenes, are an important class of compounds in organic
chemistry. They feature a specific bonding structure.
ATEX
ATEX is the abbreviation of the French term "Atmosphère explosible". ATEX stands for both
the directives of the European Community for the field of explosion protection: the ATEX
product directive 94/9/EC and the ATEX operation directive 1999/92/EC.
