3、om 9 March 2006. National foreword This standard includes safety requirements. This standard has been prepared by CEN/TC 162 Protective clothing including hand and arm protection and lifejackets (Secretariat: Germany), Working Group WG 8 Gloves. The responsible German body involved in its preparatio
4、n was the Normenausschuss Persnliche Schutz-ausrstung (Personal Protective Equipment Standards Committee), Technical Committee NA 075-05-08 AA Schutzhandschuhe. It should be noted that Technical Committee NA 075-05-08 did not vote in favour of this standard at the final voting stage because in subcl
5、ause 5.3 it specifies water penetration testing in accordance with ISO 15383. In the Committees view, this test should be carried out in accordance with DIN EN 374-2, since ISO 15383 applies only to gloves for firefighters. Amendments This standard differs from DIN EN 511:1994-11 as follows: a) The
6、requirements for extreme cold flexibility have been amended. Testing of this property is now also required for uncoated materials. b) The atmospheric conditions for the conditioning of samples have been amended. c) The contact cold test has been changed (see subclause 4.6). d) The requirements for m
7、echanical properties have been amended. e) The requirements for water penetration have been amended. f) A new informative Annex B giving information on the parameters to be considered when selecting a protective glove against cold has been introduced. g) A new informative Annex C for uncertainties o
8、f measurement and results interpretation has been introduced. h) Annex ZA for the relationship between this European Standard and EU Directive 89/686/EEC has been included.

This minimum requirement can be different according to the levels of protection against cold
28、 (see 4.5 and 4.6). 4.2 Flexibility behaviour When tested in accordance with 5.2 there shall not be any cracks. This test is not necessary for uncoated materials. 4.3 Water penetration The gloves shall be tested according to 5.3. A level of performance of 1 shall be indicated when no leakage is seen
29、 at the end of the testing period. If this requirement is not passed, then a performance level of 0 shall be indicated, and a warning stating that the EN 511:2006 (E) 5 glove may lose its insulative properties when wet shall be added in the information supplied by the manufacturer (see Clause 7). 4.
30、4 Extreme cold flexibility test When tested in accordance with 5.4 no crack shall appear at the fold. This test shall be performed on gloves designed to protect at temperatures below 30 C. 4.5 Convective cold When tested in accordance with 5.5, the thermal insulation properties of the glove shall co
31、mply with the values given in Table 1.

34、l be reported is level 1. EN 511:2006 (E) 6 5 Test methods 5.1 Conditioning Except for the convective cold test, before testing, the samples shall be stored for a minimum of 48 h in the following standard atmosphere: temperature (23 2) C; relative humidity (50 5) %. The test shall be preferably carr
35、ied out in this atmosphere. If the test is carried out under different climatic conditions then it should be started within 3 min of the time the samples were removed from the standard atmosphere. For protective gloves with a multi-layer construction the test shall be carried out on all layers simul
36、taneously, even if these, when removed, are not connected to one another (see 5.5). 5.2 Flexibility behaviour The test shall be carried out in accordance with Method A of EN ISO 7854:1997 at a test temperature of (-20 2) C or an alternative temperature as specified by the gloves manufacturer. The nu
37、mber of cycles shall be 10 000. From each palm of a pair of protective gloves two samples shall be taken (four samples in total). If the direction of manufacture of the material is recognizable then one sample shall be so taken that the longitudinal axis lies in the direction of the manufacture and
38、one in the direction at right angles to it. If the direction of manufacture is not given and one cannot be established then the two samples are taken in two directions at right angles to one another. The samples are taken without seams. If this is not possible then the sample is taken in such a way
39、that the seams lie, during the test, in the area of the clip and do not influence the bending. 5.3 Water penetration The test shall be carried out according to the whole glove integrity test described in ISO 15383, with complete immersion of the glove up to the wrist line only. 5.4 Extreme cold flex
40、ibility The test shall be carried out in accordance with ISO 4675 with a test temperature of (-50 2) C. From each palm and back of a pair of gloves a sample will be taken (four samples in total). If the direction of manufacture of the material is recognizable then one sample shall be taken so that t
41、he longitudinal axis lies in the direction of manufacture and one in the direction at right angles to it. If the direction of manufacture is not given and one cannot be established then the two samples are taken in two directions at right angles to one another. EN 511:2006 (E) 7 5.5 Convective cold
42、5.5.1 Principle The thermal insulation of a handwear is determined by measuring the power required to maintain a constant temperature gradient between the surface of a heated, full-scale hand model and the ambient atmosphere. Design and construction of the hand shall achieve the same constant temper
43、ature over the whole hand surface (maximum deviation as specified in A.4). The gloves shall be stored at test temperature for at least 24 h prior to testing. The heat input to the hand shall be sufficient to maintain a mean hand temperature in each zone in the range 30 C to 35 C at an ambient temper
44、ature, which is at least 20 C lower. 5.5.2 Apparatus The test apparatus consists of: hand model; climatic room; measuring equipment. See Annex A. 5.5.3 Test sample The test sample shall be of size 9 (see EN 420). 5.5.4 Procedure The hand model is dressed with the test glove and placed vertically, fi
45、ngers down in the test zone of the climatic room. The ambient temperature (TA) is set sufficiently low to meet the requirements of Annex A. The air velocity is kept at (4 0,5) m/s and relative humidity (50 5) %. Alternative conditions may be used provided correlation between the results obtained is
46、demonstrated. When the temperature of the hand (THand) and power consumption (QHand) have reached a steady state, the measurements are taken of their average values for a period of 10 min. The resultant thermal insulation is calculated by: HandAHandTRQTTI= TRI is the resistance to dry heat loss from
47、 the hand, which includes the resistance provided by the handwear and the air layer around the dressed model; THandis the mean surface temperature of the measuring zone of the hand, in C; TAis the mean temperature of the air in the climatic room, in C; QHandis the measured power supply to the measur
48、ing zone of the hand during steady state, in W/m2. EN 511:2006 (E) 8 The average of two independent measurements is used as the mean value for the test glove. 5.6 Contact cold The test shall be carried out in accordance with ISO 5085-1 using a pressure of 6,9 kPa and expressing the results in m K/W.
49、 Two representative samples of the material used to construct the palm side of the fingers of the glove shall be tested. If this is not possible, then sufficient samples shall be taken from the palm side of a number of gloves. If the palm side of the glove is not uniform, then samples of the different parts of the glove shall be tested and the lowest mean value quoted. NOTE an alternative test method may be used provided it has been cross-validated against the method described above
