Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation (ISO 12629:2022)

This document specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products.
It is intended to be used for homogeneous materials (see NOTE below) and for products which can have integral skins or adhered facings of some different material.
NOTE      A material is considered to be homogeneous in terms of mass distribution if its density is approximately the same throughout, i.e. if the measured density values are close to its mean density.

Wärmedämmstoffe für die Haustechnik und für betriebstechnische Anlagen - Bestimmung der Wasserdampfdurchlässigkeit von vorgeformten Rohrdämmstoffen (ISO 12629:2022)

Dieses Dokument legt Prüfeinrichtungen und Verfahren zur Bestimmung der Wasserdampf-durchlässigkeits Eigenschaften von Probekörpern aus vorgeformten Rohrdämmstoffen im stationären Zustand unter definierten Prüfbedingungen fest. Es gilt für Wärmedämmprodukte.
Es ist dafür vorgesehen, bei homogenen Dämmstoffen (siehe nachfolgende ANMERKUNG) und bei Produk¬ten, die bestimmte Oberflächenschichten oder Kaschierungen aus anderen Werkstoffen enthalten können, angewendet zu werden.
ANMERKUNG   Ein Dämmstoff wird hinsichtlich seiner Massenverteilung als homogen angesehen, wenn seine Dichte überall etwa gleich ist, das heißt, wenn die gemessenen Werte nahe beim Mittelwert seiner Dichte liegen.

Produits isolants thermiques pour les équipements de bâtiments et les installations industrielles - Détermination des propriétés de transmission de la vapeur d'eau des coquilles isolantes préformées (ISO 12629:2022)

Le présent document spécifie les équipements nécessaires et les modes opératoires à suivre pour déterminer, à l’équilibre et dans des conditions d’essai spécifiées, les propriétés de transmission de la vapeur d’eau d’éprouvettes constituées de coquilles isolantes préformées. Il s’applique aux produits isolants thermiques.
Il est destiné aux matériaux homogènes (voir NOTE ci-dessous) et aux produits qui peuvent posséder des revêtements intégrés ou des parements collés faits d’un autre matériau.
NOTE         Un matériau est estimé homogène quant à sa distribution massique si sa masse volumique est à peu près la même partout, c’est-à-dire si les valeurs mesurées de la masse volumique sont proches de sa masse volumique moyenne.

Toplotnoizolacijski proizvodi za opremo stavb in industrijske inštalacije - Ugotavljanje lastnosti prenosa vodne pare predoblikovanih cevnih izolacij (ISO 12629:2022)

Ta evropski standard določa opremo in postopek za ugotavljanje lastnosti prenosa vodne pare v stacionarnem stanju pod določenimi preskusnimi pogoji za preskusne vzorce predoblikovanih cevnih izolacij. Uporablja se za toplotnoizolacijske proizvode.
Namenjen je za uporabo za homogene materiale (glej OPOMBO) in za proizvode, ki lahko imajo vdelane prevleke ali dodane sloje iz različnih materialov.
OPOMBA:   Material je v smislu porazdelitve mase homogen takrat, ko je njegova gostota v celoti približno enaka, tj. če so izmerjene vrednosti gostote blizu njegovi povprečni gostoti.
Vrednosti stopnje prenosa vodne pare in prepustnosti so specifične za debelino preskušancev (tj. proizvod). Za homogene proizvode je prepustnost vodne pare lastnost materiala.
Če je cevna izolacija izrezana iz ploščatega proizvoda, je mogoče lastnosti prenosa vodne pare pridobiti s preskusi, izvedenimi na ploščatem proizvodu s podobnimi lastnostmi v skladu s standardom EN 12086.

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. Each 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, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
