Paints and varnishes - Artificial weathering including acidic deposition (ISO 15110:2017)
This document specifies a so-called acid dew and fog test (ADF test) as an accelerated laboratory
test method for simulating, by the use of artificial acidic precipitation, the damaging effects of acidic
atmospheric precipitation in association with UV radiation, neutral condensed precipitation, and
changing temperature and humidity. This test method is intended to be used in evaluating, on the basis
of relative performance rankings, the suitability of painted materials for use in outdoor environments
with acidic precipitation. It is not intended to generate the same extent of damage or the same damage
pattern as in outdoor weathering, but rather to give a ranking which is similar to that which would be
obtained in outdoor weathering. The method produces damage which is more homogeneous, allows
fewer specimens to be exposed (and hence more rapid testing) and enables evaluation of the exposed
specimens to be carried out using methods which are more objective than visual assessment.
Beschichtungsstoffe - Künstliches Bewittern mit saurer Beanspruchung (ISO 15110:2017)
Diese Internationale Norm legt einen sogenannten Acid-Dew-and-Fog-Test (ADF-Test) als zeitraffendes Laborprüfverfahren zum Simulieren der schädigenden Wirkung saurer atmosphä¬rischer Niederschläge im Zusammenwirken mit UV-Strahlung, neutralen Niederschlägen und wechselnder Temperatur und relativer Luftfeuchte unter Verwendung eines künstlichen sauren Nieder¬schlages fest. Dieses Prüfverfahren ist geeignet, auf der Grundlage einer relativen Rangfolge eine Auswahl von Beschichtungen für den Einsatz in einer durch saure Niederschläge belasteten Umwelt zu erarbeiten. Der ADF-Test beabsichtigt nicht, gleiche Schädigungs¬größe und -muster wie bei der Bewitterung im Freien zu erzeugen, sondern eine ähnliche Rangfolge der Schädigung wie bei der Bewitterung im Freien zu ergeben. Das Verfahren ergibt eine gleichförmige Schädigung, erlaubt kleinere Probengrößen (und damit eine schnellere Durchführung) und ermöglicht im Gegensatz zur bisher üblichen subjektiven visuellen Beurteilung das Anwenden objektiver Beurteilungsverfahren.
Peintures et vernis - Vieillissement artificiel comportant un dépôt acide (ISO 15110:2017)
ISO 15110:2017 spécifie un essai dit à la rosée et au brouillard acides (essai ADF), une méthode d'essai accéléré en laboratoire qui simule, par l'utilisation de précipitations acides artificielles, la détérioration sous l'effet de précipitations atmosphériques acides combinées au rayonnement UV, à la condensation de précipitations neutres et à des variations de température et d'humidité. Cette méthode d'essai est destinée à évaluer l'aptitude à l'emploi de matériaux peints dans des environnements extérieurs comportant des précipitations acides en les classant selon leurs performances relatives. Son but n'est pas de reproduire des détériorations de même étendue ou le même mode de détérioration que dans le cas du vieillissement en extérieur, mais d'établir un classement analogue à celui qui serait obtenu dans des conditions de vieillissement en extérieur. La méthode provoque des détériorations plus homogènes et permet d'exposer un nombre moins important d'éprouvettes (et donc de réduire la durée des essais). Elle permet également d'évaluer les éprouvettes exposées à l'aide de méthodes plus objectives que l'examen visuel.
Barve in laki - Umetno vremensko staranje, vključno s kislimi padavinami (ISO 15110:2017)
Ta dokument določa tako imenovani preskus s kislinsko rositvijo in meglo (ADF), ki je pospešena laboratorijska preskusna metoda za simulacijo škodljivih vplivov kislih atmosferskih padavin v povezavi z ultravijoličnim sevanjem, nevtralnimi kondenziranimi padavinami ter spremenljivo temperaturo in vlažnostjo z uporabo umetnih kislih padavin. Ta preskusna metoda se uporablja pri vrednotenju ustreznosti barvanih materialov za uporabo v zunanjem okolju s kislimi padavinami na podlagi njihove relativne uspešnosti. Ni namenjena temu, da bi povzročila enak obseg poškodb ali enak vzorec poškodb kot pri zunanjem klimatskem preskušanju, ampak temu, da zagotovi razvrščanje, ki je podobno razvrščanju pri zunanjem klimatskem preskušanju. Metoda povzroči poškodbe, ki so bolj homogene, izpostavi manj vzorcev (zato je preskušanje hitrejše) in omogoča, da se vrednotenje izpostavljenih vzorcev opravi po metodah, ki so objektivnejše od vizualne ocene.

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

This second edition cancels and replaces the first edition (ISO 15110:2013), which has been technically
revised. The main changes compared to the previous edition are as follows:
— the scope has been restricted to paints and varnishes;
— the black panel thermometer has been added for fluorescent UV lamps, since it gives equivalent
results to BST UV-F devices;
— exposure with uncontrolled humidity has been included as a new type U ADF test, since it has been
shown that control of humidity does not affect type of pinpoint damage resulting from this test.

Introduction
This document specifies a method of simulating the damaging effect of outdoor weathering with
relevance to acidic atmospheric precipitation on painted products. The mechanisms differ from those
of harmful gases, which essentially constitute the initial products of acidic precipitation.
Arising from changing industrial air pollution and additionally diffused by the stochastic wind and cloud
distribution, acidic precipitation occurs sporadically. Thus, especially regarding acidic precipitation,
outdoor weathering effects vary enormously within different years. Therefore, it is practically
impossible to obtain reliable outdoor exposure results from just one season. These fluctuations can
be avoided through the use of a laboratory test where all weathering parameters, including the acidic
deposition, can be controlled.
[9]
The method is based on VDI Guideline VDI 3958-12 .

4 Principle
The combined action of solar UV radiation, heat, humidity, wetting and acidic deposition is simulated in
weathering devices similar to those described in ISO 4892-2 and ISO 16474-2 for xenon-arc lamps and
in ISO 4892-3 and ISO 16474-3 for fluorescent UV lamps.
Included in the artificial exposure is an acidic exposure, which is accomplished by a once-per-day
spraying of acid. The aim of this test is not to reproduce the visual damage patterns which result from
outdoor exposures, which show a very widespread distribution that is hard to evaluate. Rather, the
aim is to reproduce the same ranking which would be obtained with an outdoor exposure, by causing
damage by the same mechanisms but creating a homogeneous distribution on a smaller scale that can
be evaluated in an objective way.

SIST EN ISO 15110:2017
ISO 15110:2017(E)
Accelerated weathering is achieved by the serial arrangement of the worst conceivable combinations of
environmental conditions for the object under test (referred to hereafter as the “worst-case scenario”).
This is accomplished by reproducing these environmental conditions in a more compressed sequence
than would be the case outdoors and by including artificial acidic precipitation. However, the values of
the environmental conditions used do not significantly exceed those encountered in practice outdoors.
5 Apparatus
5.1 General
For this test, weathering devices as specified in either ISO 16474-2 or ISO 16474-3 shall be used. The
test chamber, as well as the specimen holders, shall be made of acid- and UV-resistant materials.
5.2 Laboratory radiation sources
5.2.1 Fluorescent UV lamp apparatus, in accordance with that specified for ISO 16474-3:2013,
method A, using type 1A lamps.
For a fluorescent UV lamp apparatus giving the spectral distribution specified for ISO 16474-3:2013,
−2
method A, a UV irradiance of: E = (45 ± 5) W⋅m , constant over time and uniformly applied to the
UV
specimens in the weathering device, shall be achieved in the spectral range 290 nm to 400 nm; or
–2 –1
E = (0,76 ± 0,08) W⋅m ⋅nm at 340 nm.
λ
5.2.2 Xenon-arc lamp apparatus, in accordance with that specified for ISO 16474-2:2013, method A.
Irradiance uniformity shall be in accordance with the requirements specified in ISO 16474-1. For a
xenon-arc lamp apparatus, equipped with daylight filters, giving the spectral distribution specified for
−2
ISO 16474-2:2013, method A, the UV irradiance shall be E = (60 ± 5) W⋅m in the spectral range
UV
300 nm to 400 nm.
5.3 Test chamber.
The design of the test chamber may vary, but it shall be constructed from inert material, meeting
the requirements of ISO 16474-1 and ISO 16474-2 or ISO 16474-3, respectively. For xenon-arc lamp
apparatuses, the test chamber shall provide for control of both black standard temperature and chamber
air temperature, meeting the requirements of ISO 16474-1. For fluorescent UV apparatuses, the test
chamber shall provide for control of either black standard temperature, black panel temperature, or
chamber air temperature, meeting the requirements of ISO 16474-1. When specified herein, humidity
control shall also meet the requirements of ISO 16474-1. Devices shall also produce water spray. Water
used for the water spray shall meet the purity requirements of ISO 16474-1. The weathering device
shall be capable of completing the change from each climatic phase to the next during the ADF test
within 30 min.
5.4 Wetting system.
The test chamber shall be equipped with a means of introducing an intermittent spray of water onto the
front of the test specimens, under specified conditions. The spray system shall be made from corrosion-
resistant materials that do not contaminate the water employed.
The water spray system in xenon-arc lamp instruments shall be as specified in ISO 16474-2.
5.5 Specimen holders.
The specimen holders shall be made from inert materials that will not affect the test results, for example
non-oxidizing alloys of aluminium, or stainless steel. Brass, steel or copper shall not be used.

5.6 Black standard or black panel thermometer.
The black standard thermometer or black panel thermometer (for fluorescent UV apparatuses) used
shall comply with the requirements for these devices that are given in ISO 16474-1.
5.7 Humidity sensor.
If required, use a hygrometer for measuring the relative humidity.
5.8 Acid spray device.
A manually operated atomizer or an automatic spraying device may be used.
5.9 Radiometer.
When a radiometer is used, it shall comply with the requirements of ISO 16474-1.
6 Solutions for artificial acidic deposition
Prepare an acid mixture with a pH of 1,5 at (25 ± 2) °C by dissolving 10,6 g of H SO , 3,18 g of HNO
2 4 3
and 1,80 g of HCl in 10 l of distilled or deionized water (this gives a mass ratio of 1,0:0,3:0,17). These
quantities refer to acids with a calculated concentration of 100 %. Depending on the mass concentrations
of the acids available, larger quantities of acid might have to be weighed out (e.g. if 36 % HCl is used, the
quantity will have to be 1,8/0,36 = 5,0 g). Analytical-grade acids shall be used.
Then prepare a solution with a pH of 2,5 by diluting the pH 1,5 solution with distilled or deionized
water by a volume ratio of 1:10.
The pH 2,5 solution is the recommended solution. However, the more aggressive pH 1,5 solution may be
used if agreed upon by the interested parties. If the pH 1,5 solution is used, this shall be mentioned in
the test report.
Before starting the exposure, check the pH-value of the solution using, for instance, pH test strips. If it
deviates by more than pH 0,3 from the theoretical value, replace the solution.
To avoid changes in the pH-value of the solution, store it in an airtight container.
Acid spraying may be carried out either manually or automatically (see 9.3).
7 Test specimens
7.1 General
All specimens shall be permanently marked.
NOTE The specimens will be delivered by a customer or specifically prepared for this test or taken from
a building component. Guidelines for preparation are given in ISO 1514. Guidelines for sampling are given in
ISO 15528.
7.2 Specimen size
The specimen size shall be such that the condition of the specimens can be unambiguously ascertained
before and after the ADF test.
Due to the homogeneity of the damage on exposed specimens, only relatively small areas need to be
2
evaluated. The minimum exposed surface area shall be 30 cm , with the shortest edge at least 50 mm
in length. This reduces local variation in the acid deposition (e.g. due to the spraying procedure or edge
effects).

7.3 Corrosion of the substrates
If possible, the substrate used should be the same as that to which the coating material will be applied
in practice. It shall be made, as far as possible (see below), from inert material.
If the possibility of corrosion or delamination at the edges cannot be excluded, suitable edge protection
should preferably be provided. Also, exposed edges and substrate surfaces that might react with acidic
precipitation (e.g. those made of non-stainless steels, aluminium, copper, zinc or concrete) should be
suitably protected.
7.4 Reference specimens
The use of reference specimens is recommended for assessing the repeatability. Reference specimens of
the same type of material as employed in previous test series should be used.
If possible, these reference specimens should be made of materials which do not change with time (i.e.
do not age) under normal storage conditions.
8 Designation of test type
Exposures carried out under conditions corresponding to the subtropical climate of Jacksonville in
Florida (i.e. those of type J as defined in Table 1) are designated:
ISO 15110, ADF-J test
Exposures carried out under conditions corresponding to a moderate climate like that of central Europe
(i.e. those of type M as defined in Table 2) are designated:
ISO 15110, ADF-M test
Exposures carried out without humidity control (i.e. those of type U as defined in Table 3) are
designated:
ISO 15110, ADF-U test
9 Procedure
9.1 General
The ADF test may be performed in weathering devices as described in ISO 16474-1, ISO 16474-2 or
ISO 16474-3.
If damage occurs unexpectedly fast, it is recommended that a check be carried out to determine if
the damage really results from the synergistic action of the acid and the weathering, by performing
separate acid and weathering exposures. For the acid-free weathering exposure, the same weathering
conditions should preferably be used. For the pure acid exposure, ISO 2812-5 or ISO 175 could be used.
NOTE 1 Testing in different types of weathering device can lead to different results.
NOTE 2 To differentiate between the special action of the acidic deposition and that of usual weathering
effects, it can be useful to expose a second set of specimens to the same weathering exposure in parallel, but
without acidic deposition.
The specimens may be mounted either in an open frame or on a solid backing.
NOTE 3 If backing is used, the presence of a space between the backing and the test specimens can affect the
results.
