Conservation of Cultural Heritage - Surface protection for porous inorganic materials - Laboratory test methods for the evaluation of the performance of water repellent products
This European Standard specifies the methodology for laboratory evaluation of the performance of water repellent products on porous inorganic materials.
It is based on the measurement of several parameters which assess the performance of the product using standard test methods before and after ageing.
Acceptable performance within the laboratory does not constitute a blanket endorsement of application in every situation. The particular context of the heritage object, including such factors as material designation, condition, exposure, salt content and problems related to water ingress requires further investigation.
Erhaltung des kulturellen Erbes - Oberflächenschutz für poröse anorganische Materialien - Laborprüfverfahren für die Ermittlung der Wirksamkeit von wasserabweisenden Produkten
Die vorliegende Europäische Norm legt die Verfahrensweise für die Ermittlung der Wirksamkeit von wasserabweisenden Produkten auf porösen anorganischen Materialien im Labor fest.
Sie beruht auf der Messung mehrerer Parameter, die die Wirksamkeit des Produkts unter Verwendung von Standardprüfverfahren vor und nach der Alterung bewerten.
Eine angemessene Wirksamkeit unter Laborbedingungen stellt keine pauschale Bestätigung einer Anwendbarkeit in jeder Situation dar. Es ist vielmehr erforderlich, dass der spezielle Kontext des Gegenstands des Kulturerbes, einschließlich solcher Faktoren wie Materialbezeichnung, Erhaltungszustand, Beanspruchung, Salzgehalt und eindringendes Wasser, näher betrachtet wird.
Conservation du patrimoine culturel - Protection de surface des matériaux inorganiques poreux - Méthodes d'essai en laboratoire pour l'évaluation des performances des produits hydrofuges
La présente Norme européenne spécifie la méthodologie pour l'évaluation en laboratoire des performances de produits hydrofuges sur des matériaux inorganiques poreux.
Cette norme repose sur le mesurage de plusieurs paramètres qui permettent d'apprécier les performances du produit à l'aide de méthodes d'essai standard avant et après vieillissement.
Des performances acceptables en laboratoire ne constituent pas une approbation globale de l'application dans chaque situation. Le contexte particulier de l'objet patrimonial, notamment des facteurs tels que la désignation du matériau, l'état de conservation, l'exposition, la salinité et les problèmes liés à la pénétration de l'eau, nécessite une enquête plus approfondie.
Ohranjanje kulturne dediščine - Zaščita površine poroznih anorganskih materialov - Laboratorijske preskusne metode za vrednotenje učinkovitosti vodoodbojnih sredstev
Ta evropski standard določa metodologijo za laboratorijsko vrednotenje učinkovitosti vodoodbojnih sredstev na poroznih anorganskih materialih.
Temelji na merjenju več parametrov, ki ocenjujejo učinkovitost sredstva z uporabo običajnih preskusnih metod pred staranjem in po njem.
OPOMBA: Sprejemljiva učinkovitost v laboratoriju ne pomeni zajamčenega zagovarjanja uporabe v vseh položajih ohranjanja. Priporoča se, da se dodatno raziščejo posamezne okoliščine predmeta kulturne dediščine, med drugim dejavniki, kot so označevanje materiala, stanje ohranjenosti, izpostavljenost, vsebnost soli in težave, povezane z vdiranjem vode.

contact angle, in °. 5 Test methods for evaluation The methods listed here below are used for the evaluation of a water repellent product in relation to the possible changes of the characteristics of porous inorganic materials. 1) Determination of water absorption by capillarity (EN 15801) 2) Determination of static contact angle (EN 15802) 3) Determination of water vapour permeability (EN 15803) 4) Colour measurement of surfaces (EN 15886) 5) Determination of water absorption by pipe method (EN 16302) 6) Determination of drying properties (EN 16322) 7) Gloss measurement (EN ISO 2813) 6 Evaluation of long term performances Water repellents are expected to demonstrate suitable durability on exposure to natural weathering or laboratory tests (such as light irradiation, freeze and thaw, wetting and drying, thermal cycles, salt crystallization, pollutant simulation, biological growth, etc.) representing the environment in which the object is located. In the event that a specific methodology for the assessment of environmental degradation is standardised in the field of conservation of cultural heritage, it shall be used. Where these do not exist, a suitable assessment method for Cultural Heritage should be used and described in the test report. It is important to monitor the performances of water repellent products after ageing repeating the tests listed in Clause 5, taking into account that different comparisons of the results are possible (i.e. after ageing-before treatment or after ageing-before ageing, etc…). The comparison of the results allow to evaluate the durability of products. 7 Test equipment for the treatment (apparatus and reagents) 7.1

The number of specimens is also dependent on the heterogeneity of the material. In case of anisotropy, the specimens shall always be tested according to the same orientation. All dimensions shall have a ± 0,5 mm tolerance. The constraints of sampling material from the cultural heritage may limit sizes and numbers of samples. However, they should be as close to the requirements above as possible. When evaluating inorganic porous materials from cultural heritage, the sampling shall follow EN 16085. SIST EN 16581:2015
