m) ISO
Headquartered in Switzerland, the International
Organization for Standardization (Organization
internationale de normalisation), widely known as
ISO, is an international-standard-setting body
composed of representatives from various
national standards organizations. Founded in1947,
the organization promotes and communicates
world-wide proprietary industrial and commercial
standards. While ISO defines itself as a non-
governmental organization, its ability to set
standards that often become law, either through
treaties or national standards, makes it more
powerful than most non-governmental
organizations. In practice, ISO acts as a
consortium with strong links to governments.
Most of the ISO standards for insulation focus on
the testing of material properties and are
embedded in, for instance, EN standards.

n) VDI 2055
Verein Deutscher Ingenieure (VDI) (English:
Association of German Engineers) is an organization
of engineers and natural scientists. Established in
1856, today the VDI is the largest engineering
association in Western Europe. The role of the VDI
in Germany is comparable to that of the American
Society of Civil Engineers (ASCE) in the United
States. The VDI is not a union. The association
promotes the advancement of technology and
represents the interests of engineers and of
engineering businesses in Germany.
VDI 2055 is the most important guideline for
industrial/mechanical insulation. The scope of the
guideline includes heat and cold insulation of
technical industrial plants and technical building
equipment, such as pipes, ducts, vessels,
appliances, machines and cold stores. The
minimum insulation thicknesses for heat
distribution and warm water pipes in technical
building equipment with respect to Germany, are
laid down in the regulations concerning energy-
saving heat insulation and energy-savings in
buildings (EnEV Energy Saving Ordinance). The
considerations expressed in this guideline may
lead to other insulation thicknesses. With regard
to heat insulation in the construction industry,
both the EnEV and DIN standard 4108.
Legal requirements must be observed with regard
to the fire performance of insulation and the fire
resistance classes of insulation, such as federal
state building regulations [Landesbauordnungen]
and the piping system guidelines of the federal
states [Leitungsanlagen-Richtlinien der
Bundesländer].
The VDI guideline 2055 also serves as a
benchmark for thermo technical calculations and
measuring systems in relation to industrial and
building services installations and for guarantees
and conditions of supply with regard to those
installations. The guideline covers in detail the
calculation of heat flow rates, the design of the
insulation thickness according to operational and
economic aspects, the technical warranty
certificate and the technical conditions in respect
of delivery quantities and services. Furthermore,
the guideline examines measuring systems and
testing methods (for quality assurance).
The VDI 2055 consists of:
Part 1: Bases for calculation
Part 2: Measuring, testing and certification of
insulation materials
Part 3: Conditions of supply and purchasing of
insulation systems
