i) DIN Standards & Guidelines
Deutsches Institut für Normung e.V. (DIN; in
English, the German Institute for Standardization)
is the German national organization for standardi-
zation and is that country’s ISO member body.
DIN is a registered association (e.V.), founded in
1917, originally as Normenausschuss der
deutschen Industrie (NADI, Standardization
Committee of German Industry). In 1926, the NADI
was renamed Deutscher Normenausschuss (DNA,
German Standardization Committee) in order to
indicate that standardization covered many fields,
not just industrial products. In 1975 the DNA was
finally renamed DIN. Since 1975, it has been
recognized by the German government as the
national standards body and represents German
interests at international and European level.
The acronym DIN is often wrongly expanded as
Deutsche Industrienorm (German industry
standard). This is largely due to the historic origin
of the DIN as NADI. The NADI indeed published
their standards as DI-Norm (Deutsche Industrien-
orm, German industry standard).
Designation
The designation of DIN standards shows its origin.
DIN # is used for German standards with
primarily domestic significance or designed as a
first step toward international status.
E DIN # is a draft standard and DIN V # is a
preliminary standard.
DIN EN # is used for the German edition of
European standards.
DIN ISO # is used for the German edition of ISO
standards.
DIN EN ISO # is used if the standard has also
been adopted as a European standard.
DIN standards for the validation of insulation
materials can be found under European standards.
DIN 4140 “Insulation work on industrial installa-
tions…” gives guidelines for the validation of
insulation material, mounting and fixing. This
standard applies to insulation works on industrial
plants. These are production and distribution
plants for the industry and for technical building
appliances, (e.g. appliances, vessels, columns,
tanks, steam generators, pipes, heating and
ventilation systems, air conditioning units,
refrigeration units and hot water installations).
With requirements relating to fire protection, the
relevant standards or national technical approvals
must be observed. This standard does not apply to
insulation works performed on building shells,
interior walls and inserted ceilings, neither in the
shipbuilding and vehicle manufacturing industry,
nor within the control area of power plants.
