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. 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 of the EN ISO 13997:1999 TDM cut resistance test; classified according to the minimum requirements for each level shown in Tables 1 and 2. NOTE 1 Gloves meeting the requirements for resistance to puncture may not be suitable for protection against sharply pointed objects such as hypodermic needles.

EN 388:2016+A1:2018 (E) 8 4.2.2 Impact protection Each area where impact protection is claimed shall be tested. Due to the test method (test specimens dimensions), protection against impacts on fingers cannot be tested. A protective glove against mechanical risks may be designed and constructed to provide specific impact attenuation (for example, impact protection of knuckles, back of the hand, palm,). These gloves shall comply with the following requirement. When the tests were carried out according to 6.6, performance shall conform to Level 1 of 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. 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. NOTE 1 A suitable abradant has been tested by the standardization group, the Klingspor PL31B, Grit 1801) (see Annex A).

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. SIST EN 388:2016+A1:2019

EN 388:2016+A1:2018 (E) 9 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. 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). SIST EN 388:2016+A1:2019

EN 388:2016+A1:2018 (E) 10 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 SIST EN 388:2016+A1:2019

EN 388:2016+A1:2018 (E) 11 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
