Thermal insulation - Physical quantities and definitions (ISO 7345:1987)

Defines physical quantities used in the field of thermal insulation, i.a. quantity of heat, heat flow rate, density of heat flow rate, thermal conductivity, thermal resistance, thermal transmittance, heat capacity, thermal diffusivity, thermal effusivity etc., and gives the corresponding symbols and units.

Wärmeschutz - Physikalische Größen und Definitionen (ISO 7345:1987)

Diese Internationale Norm definiert physikalische Größen aus dem Bereich des Wärmeschutzes und enthält die entsprechenden Symbole und Einheiten. ANMERKUNG: Da der Anwendungsbereich dieser Internationalen Norm auf den Bereich des Wärmeschutzes beschränkt ist, unterscheiden sich einige der in Abschnitt 2angegebenen Definitionen von den Definitionen in ISO 31/4 "Größen und Wärmeeinheiten". Diese Begriffe sind mit einem Stern gekennzeichnet.

Isolation thermique - Grandeurs physiques et définitions (ISO 7345:1987)

La présente Norme internationale définit les grandeurs physiques utilisées dans le domaine de l'isolation thermique, et donne les unités et symboles correspondants.
NOTE -- Étant donné que l'objet de la présente Norme internationale est limité à l'isolation thermique, certaines définitions données au chapitre 2 différent de celles données dans l'ISO 31/4, Grandeurs et unités de chaleur. Pour identifier de telles différences, un astérisque a été inséré avant le terme concerné.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7345 was prepared by Technical Committee ISO/TC 163,
Thermal insula tion .
This second edition cancels and replaces the first edition (ISO 7345 : 1985) ; clauses 0
and 3 are new.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.

1 Scope and field of application
This International Standard defines physical quantities used in the field of thermal insulation, and gives the corresponding Symbols
and units.
NOTE - Because the scope of this International Standard is restricted tothermal insulation, some of the definitions given in clause 2 differ from those
given in ISO 31/4, Quantities and units of heat. To identify such differentes an asterisk has been inserted before the term concerned.
