EN 13594:2015, Table 7.
5 Sampling and conditioning
5.1 Conditioning of samples and all other test consumables (e.g. abrasive paper, EPDM, cotton
canvas) is as follows:
— temperature (23 ± 2) °C;
— relative humidity (50 ± 5) %.
The period of conditioning is at least 24 h. Tests shall preferably be performed in the above mentioned
environment.

---------------------- Page: 9 ----------------------
SIST EN 388:2016
EN 388:2016 (E)
5.2 If the test is performed in a different environment and if the testing duration does not exceed 15
min, it shall be started within 5 min after removal from the conditioning.
5.3 If special applications require testing in a different environment, it is the responsibility of the
manufacturer or his authorized representative to arrange for additional tests and to present the results
including a full description of the testing environment in the information supplied by the manufacturer
(Clause 8).
6 Test methods
6.1 Abrasion resistance
6.1.1 Principle
Circular specimens of material are abraded under known pressure with a cyclic planar motion in the
form of a Lissajous figure which is the result of the simple harmonic motions at right angles to each
other. The resistance to abrasion is measured by the number of rubs required for breakthrough to
occur.
6.1.2 Consumables
6.1.2.1 Abradant
An abradant shall meet the requirements as laid down in Annex A.
1)
NOTE 1 A suitable abradant has been tested by the standardization group, the Klingspor PL31B, Grit 180 (see
Annex A).
NOTE 2 At the present time, only one calibration procedure is available using textile reference material. A more
robust calibration method for other reference material is still under construction.
6.1.2.2 Double-sided adhesive tape
The double sided adhesive tape shall be used to provide adhesion of the sample during the test to
achieve reproducible results. The mean adhesion value shall be of minimum 0,20 N/mm.
Tests are carried out according to the method given in Annex C.
NOTE 1 If the adhesion is not sufficient, the sample will move during the test and in this case a tear
phenomenon can be observed rather than abrasion.
NOTE 2 Examples of suitable double sided adhesive tapes are provided in C.5. Alternative tapes can be verified
for suitability using the test method defined in Annex C.
6.1.3 Apparatus
An abrasion machine of the type described in EN ISO 12947-1 as a Martindale Wear and Abrasion is
required. It shall fulfil the following requirement:
Pressure on specimen: (9,0 ± 0,2) kPa.
1) Klingspor PL31B, Grit 180 is the trade name of a product supplied by KLINGSPOR Schleifsysteme GmbH & Co. KG,
Hüttenstraße 36, D-35708 Haiger. This information is given for the convenience of users of this European Standard and
does not constitute an endorsement by CEN of the product named. Equivalent products may be used if they can be
shown to lead to the same results.

---------------------- Page: 10 ----------------------
SIST EN 388:2016
EN 388:2016 (E)
6.1.4 Test specimens
Four test specimens shall be taken from four individual gloves of the same glove series. In case of an
irregular design of the palm, the test specimen shall be taken in the area where the least protection is
expected (remove the reinforcements that do not cover the whole palm).
Where the test specimen is made of several unbounded layers, the test is performed on each layer.
When the specimen is made of bonded layers if the layers can be separated without damaging the
material, the test must be performed on each layer independently. Otherwise, the test must be
performed on all layers, taking care not to have a seam in the test area.
6.1.5 Test procedure
6.1.5.1 Setting up the machine
6.1.5.1.1 Mounting test specimens
Cut four test specimens to the correct dimensions, diameter (38,0 ± 0,5) mm. Secure the test specimen
without tension carefully and centrally on the metal insert by means of double-sided adhesive tape
under a weight of approximately 10 kg applied for at least 5 min. Good adhesion can be achieved
through the use of double-sided tape which prevents loosening of the test specimen and the inclusion of
air bubbles. Place the ring of the specimen holder in position on the mounting plate provided on the
base of the machine.
In order to test the materials that are thicker than the standard ring (for example leather with a
thickness greater than 1,2 mm), the diameter of the opening of the clamping ring should be increased
(see Figure 1).
9
---------------------- Page: 11 ----------------------
SIST EN 388:2016
EN 388:2016 (E)
Dimensions in millimetres
Figure 1 — Alternative clamping ring for thick material
Some materials might need a longer contact time to ensure maximum adhesion between the test
specimen and the adhesive tape. Surface treatment (e.g. removal of fluff) may be used in order to
improve adhesion between the test specimen and the adhesive tape, provided this treatment will not
affect the performance of the material during the test. If a different contact time (> 5 min) and/or if a
surface treatment is used, this should be reported.
While ensuring that the ring containing the specimen and metal insert is held firmly in the mounting
plate, start to screw the top of the specimen holder on to the ring, taking care that the screw threads are
not crossed. Having started the screwing down operation, use both hands to maintain a continuous
downwards pressure on the assembly against the mounting plate.
This procedure will normally ensure that the specimen is securely retained in the holder in a wrinkle-
free condition and that it is ready for testing.
NOTE It is important to use a sufficiently effective double-sided adhesive tape which prevents the movement
of the test specimen during the duration of the test (appropriate double-side adhesive tapes can for example be
found in the building and construction industry). This information is given for the convenience of users in
Annex C.
6.1.5.1.2 Mounting abradant
Secure carefully the abradant (6.1.2.1) by means of double-sided adhesive tape covering the whole
surface of the mounting plate. Ensure the abradant is flat by placing the weight supplied with the testing
machine for this purpose on its surface, and if a retaining frame is used, then position and tighten it up
10
---------------------- Page: 12 ----------------------
SIST EN 388:2016
EN 388:2016 (E)
evenly using diagonally opposite screws in sequence. Make sure that the abradant is held in place firmly
and that there are no tucks or ridges.
6.1.5.1.3 Mounting specimen holders
Mount the test specimen holders on the top plate under a pressure of (9,0 ± 0,2) kPa and switch on the
machine. Four test specimens are preferably to be tested at the same time on the same machine. If
tested differently, it shall be reported in the test report and the reason why.
Every time a specimen holder is taken from the machine to check the end point of the specimen for
breakthrough, retighten the specimen holder before it is replaced on the machine.
If it is necessary to interrupt the test for an appreciable length of time (e. g. overnight or at the
weekend) remove the specimens from their holders and store them face upwards. Protect the
specimens by covering them with a clean card or piece of fabric.
6.1.5.2 Method of assessment
The performance of the sample is determined by the specimen breakthrough, which is the visually
observed deterioration in a specimen after exposure to a specified number of abrasion rubs, i.e.:
— in woven fabrics, when two separate threads are completely broken, resulting in a hole to appear;
— in knitted fabrics, when one thread is completely broken, resulting in a hole to appear;
— in bonded layers, when the first hole through all layers together resulting from the wear is of a
diameter at least equal to 1 mm;
— in other materials then those mentioned above, when the first hole resulting from the wear is of a
diameter at least equal to 1 mm.
6.1.5.3 Test method
Each test will be performed with a new abradant. Begin the test and check the test specimens after
100 rubs. If there is no breakthrough, continue the test until reaching 500 rubs (performance level 2). If
there is no breakthrough, continue the test until the next performance level in Table 1 is reached.
Examine the test specimens at the required rub number for each performance level.
At each examination of a specimen at a specified performance level, both the test specimens and the
abradant shall be cleaned (e. g. by clean compressed air) and the specimen holder tightened before it is
replaced on the machine.
If a breakthrough is found when examining the test specimens at a given performance level, the
classification will be at the preceding inferior performance level.

3.6
Abrasion breakthrough
Breakthrough is reached:
- in knitted fabrics, when one thread is broken causing a hole to appear
- in other materials, when the first hole resulting from the wear is of a diameter at least equal to 1 mm
- in woven fabrics, when two separate threads are completely broken
- in bonded layers, when breakthrough is reached through all layers together
4 Requirements
The protective gloves according to this standard shall first meet all the applicable requirements of EN 420.
A protective glove against mechanical risks shall have performance level of 1 or above for at least one of the
properties (abrasion, blade cut, tear and puncture) or at least level A for the ISO cut resistance test; classified
according to the minimum requirements for each level shown in table 1.
NOTE Gloves meeting the requirements for resistance to puncture may not be suitable for protection against sharply
pointed objects such as hypodermic needles.

4.1 Additional Protection
Additional protection can be claimed when the gloves is conform to the requirements defined in the following
clause(s).
4.1.1 Impact protection
A protective glove against mechanical risks may be designed and constructed to provide specific impact
attenuation. These gloves shall be conform to the following requirement.
When the tests are performed according to the clause 6.8.2 of EN 13594:2002, with an impact energy of 5J, the
mean peak transmitted shall not be greater than 4 kN. In addition, no part of the glove shall crack or shatter
producing sharp edges, and the chamois leather between the specimen and anvil shall not be torn or holed.
5 Sampling and conditioning
5.1 All specimens shall be taken from the palm of different gloves for classification purposes. For arm
protectors, specimens shall be taken from the area for which protection is claimed.

prEN 388:2014 (E)
5.2 If relevant, additional areas of the protective glove shall be tested, e. g. for specific protection or for
areas which provide lower protection.
5.3 Conditioning of samples and all other test consumables (e.g. abrasive paper, EPDM, cotton canvas) is
as follows:
Temperature (23 ± 2) °C;
Relative Humidity (50 ± 5) %.
The period of conditioning is at least 24 h. Tests shall preferably be performed in the above mentioned
environment.
5.4 If the test is performed in a different environment, it shall be started within 5 min after removal from the
conditioning.
5.5 If special applications require testing in a different environment, it is the responsibility of the
manufacturer or his authorized representative to arrange for additional tests and to present the results
including a full description of the testing environment in the information supplied by the manufacturer
(clause 8).
6 Test methods
6.1. Abrasion resistance
6.1.1. Principle
Circular specimens of material are abraded under known pressure with a cyclic planar motion in the form of a
Lissajous figure which is the result of the simple harmonic motions at right angles to each other.
The resistance to abrasion is measured by the number of cycles required for breakthrough to occur.
6.1.2. Abradant
A suitable abradant shall meet the requirements as laid down in Annex A.
NOTE An example of suitable abradant is Klingspor PL31B, Grit 180 (see Annex A)
A more robust calibration method for defining alternative papers is still under construction.
6.1.3 Apparatus
An abrasion machine of the type described in EN ISO 12947-1 as a Martindale Wear and Abrasion is required. It
shall fulfil the following requirement:
Pressure on specimen: (9 ± 0.2) kPa
NOTE More detailed specifications relative to the apparatus can be found in EN ISO 12947-1.
6.1.4 Test specimens
Four test specimens shall be taken from four individual gloves of the same glove series. In case of an irregular
design of the palm, the test specimen shall be taken in the area where the least protection is expected.
Where the test specimen is made of several unbonded layers, the test is performed on each layer, and the
classification is based on the number of cycles for the layer with the highest performance.

6.1.5 Test procedure
Setting up the machine.
a) Mounting test specimens
+5
Cut four test specimen to the correct dimensions (38 ) mm. Secure the test specimen without tension carefully
0
and centrally on the metal insert by means of double-sided adhesive tape under a weight of 10 kg applied for at
least 5 minutes. Good adhesion can be achieved through the use of double-sided tape which prevents loosening
of the test specimen and the inclusion of air bubbles. Place the ring of the specimen holder in position on the
mounting plate provided on the base of the machine
NOTE Some materials might need a longer contact time to ensure maximum adhesion between the test specimen
and the adhesive tape Surface treatment (e.g. removal of fluff) may be used in order to improve adhesion between the test
specimen and the adhesive tape, provided this treatment will not affect the performance of the material during the test. If a
different contact time (> 5 minutes) and/or if a surface treatment is used, this should be reported.
While ensuring that the ring containing the specimen and metal insert is held firmly in the mounting plate, start to
screw the top of the specimen holder on to the ring, taking care that the screw threads are not crossed. Having
started the screwing down operation, use both hands to maintain a continuous downwards pressure on the
assembly against the mounting plate.
This procedure will normally ensure that the specimen is securely retained in the holder in a wrinkle-free
condition and that it is ready for testing.
NOTE It is important to use a sufficiently effective double-sided adhesive tape which prevents the movement of the
test specimen during the duration of the test (appropriate double-side adhesive tapes can for example be found in the
building and construction industry) . This information is given for the convenience of users of this standard and does not
constitute an endorsement by CEN/TC 162 of the product named.
b) Mounting abradant
Secure carefully the abradant (1) by means of double-sided adhesive tape covering the whole surface of the
mounting plate. Ensure the abradant is flat by on its surface, and if a retaining frame is used, then position and
tighten it up evenly using diagonally opposite screws in sequence. Make sure that the abradant is held in place
firmly and that there are no tucks or ridges.
c) Mounting specimen holders
Mount the test specimen holders on the top plate under a pressure of (9 ± 0.2) kPa and switch on the machine. 4
test specimens are preferab
