Thermal insulating products for building applications - Determination of long-term water absorption by immersion (ISO 16535:2019)

This document specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products.
This document specifies two methods:
— Method 1: Partial immersion;
— Method 2: Total immersion.
The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long-term water exposure.
The long-term water absorption by total immersion is not directly related to the conditions on site, but has been recognized as a relevant condition of test for some products in some applications.

Wärmedämmstoffe für das Bauwesen - Bestimmung der Wasseraufnahme bei langzeitigem Eintauchen (ISO 16535:2019)

Dieses Dokument legt Prüfeinrichtungen und Verfahren zur Bestimmung der langzeitigen Wasseraufnahme von Probekörpern fest. Sie gilt für Wärmedämmstoffe.
Dieses Dokument legt zwei Prüfverfahren fest:
—   Prüfverfahren 1: Teilweises Eintauchen;
—   Prüfverfahren 2: Vollständiges Eintauchen.
Die langzeitige Wasseraufnahme bei teilweisem Eintauchen simuliert die Wasseraufnahme, die sich bei langzeitigem Einwirken von Wasser ergibt.
Die langzeitige Wasseraufnahme bei vollständigem Eintauchen kann zwar nicht direkt mit den Anwendungsbeanspruchungen verglichen werden, es wurde aber als entsprechende Prüfbedingung für bestimmte Produkte bei manchen Anwendungen anerkannt.

Produits isolants thermiques destinés aux applications du bâtiment - Détermination de l'absorption d'eau à long terme par immersion (ISO 16535:2019)

Le présent document spécifie l'équipement et les modes opératoires permettant de déterminer l'absorption d'eau à long terme des éprouvettes. Il s'applique aux produits isolants thermiques.
Le présent document spécifie deux options:
— Méthode 1: immersion partielle;
— Méthode 2: immersion totale.
L'absorption d'eau à long terme par immersion partielle est destinée à simuler l'absorption d'eau causée par une exposition prolongée à l'eau.
L'absorption d'eau à long terme par immersion totale n'est pas directement liée aux conditions sur site, mais a été reconnue comme étant une condition d'essai pertinente pour certains produits dans certaines applications.

Toplotnoizolacijski proizvodi za uporabo v gradbeništvu - Ugotavljanje dolgotrajnega vpijanja vode s potapljanjem (ISO 16535:2019)

Ta mednarodni standard določa opremo in postopke za ugotavljanje dolgotrajnega vpijanja vode preskušancev. Uporablja se za toplotnoizolacijske proizvode.
Ta mednarodni standard določa dve možnosti:
– metoda 1 – delno potapljanje;
–metoda 2 – popolno potapljanje.
Dolgotrajno vpijanje vode z delnim potapljanjem simulira vpijanje vode pri dolgotrajni izpostavljenosti vodi.
Dolgotrajno vpijanje vode s popolnim potapljanjem ni neposredno povezano s pogoji na mestu uporabe, ampak se smatra kot ustrezen pogoj preskusa za nekatere proizvode pri nekaterih vrstah uporabe.

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

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

This document was prepared by the European Committee for Standardization (CEN) Technical

Committee CEN/TC 88, Thermal insulating materials and products, in collaboration with ISO Technical

Committee TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1,

Test and measurement methods, in accordance with the agreement on technical cooperation between

ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 16535:2012), which has been technically

revised. The main changes compared to the previous edition are as follows:

— The content in 5.3, 6.4, 7.1 and 10 has been revised to reflect the conditions for tropical countries.

4 Principle
4.1 Method 1: Partial immersion

The long-term water absorption by partial immersion is determined by measuring the change in mass

of a test specimen, the lower part of which is in contact with water for a period of 28 days.

The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in

method 1A or taken into account by deduction o
