21、t the mechanical risks of abrasion, blade cut, tear and puncture. This standard is only applicable in conjunction with EN 420. The test methods developed in this standard can also be applicable to arm protectors which are protective devices separate from the glove or the clothing. 2 Normative refere
22、nces This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments or revisions of any of these p
23、ublications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

A protective glove against mechanical risks shall have a performance level of 1 or
29、above for at least one of the properties (abrasion, blade cut, tear and puncture) classified according to the minimum requirements for each level shown in table 1. NOTEGloves meeting the requirements for resistance to puncture may not be suitable for protection against sharply pointed objects such a

31、ning 5.1Unless otherwise stated all specimens shall be taken from the palm of different gloves for classification purposes. 5.2If relevant, additional areas of the protective glove shall be tested, e. g. for specific protection. 5.3Conditioning of samples is as follows: ? Temperature (23 2) ?C; ? Re
32、lative Humidity (50 5) %. The period of conditioning is 24 h. Tests shall preferably be performed in the above mentioned environment. 5.4If the test is performed in a different environment, it shall be started within 5 min after removal from the conditioning. 5.5If special applications require testi
33、ng 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
34、.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
35、 of cycles required for breakthrough to occur. Breakthrough is understood to mean when a hole is worn through the test specimen.

36、lowing specifications: a) Backing: The backing shall be of a suitable quality paper with a minimum weight of 125 g/m 5 %; b) Adhesive: The adhesive shall be water soluble, of good quality and suitable for purpose; c) Abrasive: The glass used shall be of good quality, suitable for purpose and shall m

38、istics: 1) The breaking strength shall not be less than: ? Machine direction: 392 N/50 mm; ? Cross direction: 215 N/50 mm; 2) The weight of the glass paper shall be 300 g/m 10 %. 6.1.3 Apparatus An abrasion testing machine of the type described in EN ISO 12947-1 as a Martindale Wear and Abrasion mac
39、hine is required. It shall fulfil the following requirement: Pressure on specimen(9 0,2) kPa NOTEMore detailed specifications relative to the apparatus can be found in EN ISO 12947-1. The model number 103 (four places) is appropriate. 6.1.4Test specimens Four test specimens shall be taken from four
40、individual gloves of the same glove series. Where the test specimen is made of several unbonded layers, the test is performed on each layer, and the classification is based on the sum of the number of cycles. 6.1.5Test procedure Setting up the machine.

Insert a dial gauge through the spindle bearing and move the top plate by turning the drive shaft by hand. The needle movement of the dial gauge shall b
42、e within 0,05 mm over the whole surface of an abrading table. If machines are being used in which the specimen holders are connected to the weights by spindles, assemble each empty specimen holder and place each one in position on the appropriate abrading table and insert the spindles. Use a feeler
43、gauge to check for any gap between the face of the specimen holder insert and the table. The gap shall not be greater than 0,05 mm. Rock the spindle from side to side and re-check with the feeler gauge. To avoid damaging abrading tables and metal inserts, do not run the testing apparatus with metal
44、inserts in contact with the uncovered abrading table. B. Mounting test specimens Place the ring of the specimen holder in position on the mounting plate provided on the base of the testing apparatus. Secure without tension carefully and centrally the test specimen on the metal insert by means of dou
45、ble-sided adhesive tape under a weight of 10 kg applied during 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. While ensuring that the ring containing the specimen and metal insert is held firml
46、y 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 downward pressure on the assembly against the mounting plate. This procedure
47、will normally ensure that the specimen is securely retained in the holder in a wrinkle-free condition and that it is ready for testing. NOTEAn example of appropriate double-sided adhesive tape is product ref. 465 from 3M. This information is given for the convenience of users of this standard and do
48、es not constitute an endorsement by CEN/TC 162 of the product named. Equivalent products may be used if they can be shown to lead to the same results. C. Mounting abradant1) Secure carefully the abradant 1) by means of double-sided adhesive tape. Ensure the abradant is flat by placing the weight sup
49、plied with the testing machine for this purpose on its surface, and then position and tighten up the retaining frame 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. D. Mounting specimen holders Mount the test specimen holders on the top plate under a pressure of (9 0,2) kPa and switch on the testing machine. Every time a specimen holder is taken from the machine to check the end point of the s
