4 Test methods
4.1 General
4.1.1 Laboratory safety
Safety precautions — Person using this document should be familiar with normal laboratory practice.
This document does not purport to address all the safety problems, if any, associated with its use. It is
the responsibility of the user to apply established Health and Safety practices and to ensure compliance
with the applicable regulations.
4.1.2 Sampling and conditioning
The minimum number of samples, i.e. separate items of footwear, to be tested in order to verify
compliance with the requirements specified in EN ISO 20344:2021, together with the minimum number
of test pieces to be taken from each sample, are given in Table 1.
Wherever possible, test pieces shall be taken from the whole footwear item unless otherwise stated.
If it is not possible to obtain a large enough test piece from the footwear, then a sample of the material
from which the component has been manufactured may be used instead and this should be noted in the
test report.

Table 1 of EN ISO 20344:2021 is applicable
Splashing test
1 pair of shoes (the medium size of the range) per chemical yes
(4.2)
— 2 discs for outsole (one before and one after each
chemical exposure), one pair at least

If possible
(4.3)
— 2 discs for upper (one before and one after each chemical
exposure) one pair at least
Permeation test
3 discs from the weakest part of the upper for each chemical yes
(4.4)
All test pieces shall be conditioned in a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative
humidity for a minimum of 24 h before testing, unless otherwise stated in the test method.
The maximum time which shall elapse between removal from the conditioning atmosphere and the
start of testing shall be not greater than 10 min, unless otherwise stated in the test method.
For each of the required measurements performed in accordance with this document, a corresponding
estimate of the uncertainty of measurement should be evaluated. One of the following approaches
should be used:
[9]
— a statistical method, e.g. as given in ISO 5725-2:2019 ;
[10]
— a mathematical method, e.g. as given in ISO/IEC Guide 98-3:2014 ;
[11]
— uncertainty and conformity assessment as given in ISO/IEC Guide 98-4:2012 ;
[12]
— JCGM 100:2008 .
4.2 Splashing test
4.2.1 Principle
The whole footwear samples are exposed in standardized conditions for several periods of time, by
pouring of a limited volume of specific liquid chemicals.
Damage to the materials and structure of the footwear including ingress through seams and
manufactured structure is assessed at specified step of the test method.
4.2.2 Method
A pair of shoes shall be evaluated per chemical to be applied. If several chemicals have to be chosen, it is
necessary to use a new pair of footwear for each chemical:
a) clean the footwear with a dry absorbent paper to remove any productions residues;
b) lightly mark (a waxed pencil or chalk have been found to be suitable) the sides of the test sample
with a horizontal line as defined in Figure 1. The height h is given by Table 8 (Minimum height,
below which the requirements of the upper shall be fulfilled) of EN ISO 20345:2022. This is to
define the tested area (under this line) to allow accurate application of the test chemical;

Key

c) store the footwear for at least 24 h in an environment at (23 ± 2) °C and (50 ± 5) % rh. The test shall
be performed between (20 and 25) °C;
d) fill the footwear with absorbent paper as a trace medium for liquid ingress. Ensure the paper is in
contact with the seams of the footwear at the front, bellows and lacing in particular;
e) fasten the footwear (for example, by lacing);
f) prepare a minimum of 130 ml of the chosen test chemical;
g) place the footwear into a tray of a sufficient size [(30 ± 1) cm large (40 ± 1) cm long (5 ± 1) cm high]
to allow residual liquid to drain from around the footwear during application. The material
constituting the tray shall not be affected by the test chemical. Any accidental spillage during
application into the inner of the footwear shall be prevented;
h) pour (60 ± 6) ml of test liquid evenly across the two sides and front of the footwear using a
(20 ± 2) ml containers.
NOTE It has been found that using smaller containers each holding (20 ± 2) ml of the test liquid per side and
across the centre front makes application more consistent.
The footwear shall have an angle of (45 ± 10) degrees when pouring chemicals onto the side
sections. Using the 20 ml container, move along the drawn line and wet the test area of the sample.
The pouring distance shall be between 4 cm and 6 cm (see Figure 2). Leave any spilled volume in
the tray in contact with the outsole until the first examination is completed;

i) if the tested chemical has a high volatility (greater than 10 Kpa at 20 °C):
— leave the samples for a period of 2 min ± 15 s prior to removal from the tray;
For other chemicals:
— leave the samples for a period of 10 min ± 30 s prior to removal from the tray;
j) then assess any initial damage. The following changes are considered as damage:
— example given Annex B;
— discoloration, cracking, delamination, etc.;
— seam opening;
— hardening, softening, melting;
k) again, pour (60 ± 6) ml of test liquid evenly across the two sides and front of the footwear using a
(20 ± 2) ml containers;
l) 1 h (±2 min) after pouring the chemical, carry out a visual inspection of the two footwear,
comparing it to an original (or photographs) and note any damage or visual change as defined in
Annex B (for example, surface marking or damage, damage to components, lack of functionality).
Remove the absorbent paper from inside the footwear and, if any liquid penetration is visible as
damp patches, note the location of ingress.
Check the area under any lacing or fastenings where spilt liquid might be trapped and not easily
visible. Assess any initial damage (see 4.2.2 j). If necessary for a correct damage assessment, cut and
open the test sample to assess any internal damage or wetness;
m) 24 h (±30 min) after pouring the chemical, carry out a second visual inspection of the two footwear,
comparing it to an original (or photographs) and note any damage (see 4.2.2 j) or visual change as
defined in Annex B.
4.2.3 Test report
The test report shall include the following information:
a) the number and date of this document, i.e. prEN 13832-1:2025, 4.2;
b) a full description of the sample and its origin;
c) for each tested chemical:
1) a full description of the chemicals used in the splashing test,
2) the appearance of the test piece after the splashing tests (e.g. cracking, delamination) after 2 or
10 min, 1 h after the test and 24 h after the test,
3) any penetration of chemical inside the footwear,
4) any trapped chemical in the footwear (inside or outside);
d) any deviation from test methods.
4.3 Degradation test
4.3.1 Principle
Some basic physical properties of the footwear component (upper and outsole) are checked before and
after contact with chemicals.
4.3.2 Apparatus
4.3.2.1 Degradation cell. The apparatus shall be suitable for holding the test piece. A suitable
apparatus is illustrated in Figure 3 and comprises a base-plate (5) and an open-ended cylindrical
cell (4) that is held tightly against the test piece (6) by the wing nuts (1) mounted on the bolts (2).
NOTE A hole of diameter approximately 50 mm can be made in the
