Thermal insulating products for building equipment and industrial installations - Determination of trace quantities of water-soluble chloride, fluoride, silicate, sodium ions and pH (ISO 12624:2022)

This document specifies the equipment and procedures for determining trace quantities of the water-soluble chloride, fluoride, silicate and sodium ions in an aqueous extract of the product. It also describes a procedure for the determination of the pH of the aqueous extract. It is applicable to thermal insulating products.
NOTE      The determination of these parameters can be relevant for thermal insulating products intended for application to stainless austenitic steel surfaces. The presence of chloride, fluoride, silicate and sodium ions under certain conditions can influence the risk of stress corrosion cracking. See Annex B for further information on general use of this document.

Wärmedämmstoffe für die Haustechnik und für betriebstechnische Anlagen - Bestimmung des Gehalts von wasserlöslichen Chlorid-, Fluorid-, Silikat- und Natrium-Ionen und des pH-Wertes (ISO 12624:2022)

Dieses Dokument legt die Prüfeinrichtungen und Verfahren zur Bestimmung des Gehalts von wasserlöslichen Chlorid-, Fluorid-, Silikat- und Natrium-Ionen eines wässrigen Extrakts des Produkts fest. Es beschreibt außerdem ein Verfahren zur Bestimmung des pH-Werts des wässrigen Extrakts. Es gilt für Wärmedämmstoffe.
ANMERKUNG   Die Bestimmung dieser Parameter kann für Wärmedämmstoffe relevant sein, die zur Anwendung auf Oberflächen aus austenitischem nichtrostenden Stahl vorgesehen sind. Die Anwesenheit von Chlorid-, Fluorid-, Silikat- und Natrium-Ionen kann unter bestimmten Bedingungen das Risiko der Spannungsrisskorrosion beeinflussen. Siehe Anhang B für weitere Informationen zur allgemeinen Anwendung dieses Dokuments.

Produits isolants thermiques pour les équipements de bâtiments et les installations industrielles - Détermination des faibles quantités d'ions chlorure, fluorure, silicate et sodium solubles dans l'eau et mesure du pH (ISO 12624:2022)

Le présent document spécifie les équipements nécessaires et les modes opératoires à suivre pour déterminer les faibles quantités d’ions chlorure, fluorure, silicate et sodium solubles dans l’eau, ainsi que le pH d’un extrait aqueux du produit. Il s’applique aux produits isolants thermiques.
NOTE          La détermination de ces paramètres peut s’appliquer aux produits isolants thermiques appliqués sur des surfaces d’acier inoxydable austénitique. La présence d’ions chlorure, fluorure, silicate et sodium sous certaines conditions peut avoir une influence sur les risques de fissuration par corrosion sous contrainte. Voir Annexe B pour plus d’informations sur l’utilisation générale du présent document.

Toplotnoizolacijski proizvodi za opremo stavb in industrijske inštalacije - Ugotavljanje sledi vodotopnih kloridnih, fluoridnih, silikatnih in natrijevih ionov ter vrednosti pH (ISO 12624:2022)

Ta standard določa opremo in postopke za ugotavljanje sledi vodotopnih kloridnih, fluoridnih, silikatnih in natrijevih ionov v vodnem ekstraktu proizvoda. Opisuje tudi postopek za ugotavljanje vrednosti pH vodnega ekstrakta. Standard se uporablja za toplotnoizolacijske proizvode.
OPOMBA: Ugotavljanje teh parametrov je lahko relevantno za toplotnoizolacijske proizvode, namenjene za uporabo pri površinah iz avstenitnega nerjavnega jekla. Prisotnost kloridnih, fluoridnih, silikatnih in natrijevih ionov pod določenimi pogoji lahko vpliva na tveganje pokanja zaradi napetostne korozije. Za dodatne informacije glej informativni dodatek B.
