Protective gloves against cold

This European Standard specifies the requirements and test methods for gloves which protect against convective and conductive cold down to –50 °C. This cold can be linked to the climatic conditions or an industrial activity. The specific values of the different performance levels are decided by the special requirements for each class of risk or the special areas of application. Product tests may only give performance levels and not levels of protection.

Schutzhandschuhe gegen Kälte

Diese Europäische Norm legt die Anforderungen und Prüfverfahren für Schutzhandschuhe gegen konvektive
Kälte oder Kontaktkälte bis - 50 °C fest. Die Kälte kann mit den klimatischen Bedingungen oder einer
beruflichen Tätigkeit zusammenhängen. Die spezifischen Werte der verschiedenen Leistungsstufen werden
durch die speziellen Anforderungen für jede Risikoklasse oder den speziellen Anwendungsbereich bestimmt.

1 Scope This European Standard specifies the requirements and test methods for gloves which protect against convective and conductive cold down to –50 °C. This cold can be linked to the climatic conditions or an industrial activity. The specific values of the different performance levels are decided by the special requirements for each class of risk or the special areas of application. Product tests may only give performance levels and not levels of protection. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 388, Protective gloves against mechanical risks EN 420, Protective gloves — General requirements and test methods EN ISO 7854:1997, Rubber- or plastics-coated fabrics — Determination of resistance to damage by flexing (ISO 7854:1995) ISO 4675, Rubber- or plastics-coated fabrics — Low- temperature bend test ISO 5085-1, Textiles — Determination of thermal resistance — Part 1: Low thermal resistance ISO 7000, Graphical symbols for use on equipment — Index and synopsis ISO 15383, Protective gloves for firefighters — Laboratory test methods and performance requirements 3 General requirements These gloves shall meet all the applicable requirements of EN 420. 4 Performance requirements 4.1 Mechanical requirements The gloves shall at least comply with performance level 1 of EN 388 in abrasion and tear resistance. This minimum requirement can be different according to the levels of protection against cold (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 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). 4.4 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 comply with the values given in Table 1. Table 1 — Thermal insulation values Performance level Thermal insulation ITR in m2 K/W 1 0,10 ≤ ITR < 0,15 2 0,15 ≤ ITR < 0,22 3 0,22 ≤ ITR < 0,30 4 0,30 ≤ ITR

For a convective cold performance level of 2 to 4, the product shall record at least level 2 in abrasion and tear resistance according to EN 388, otherwise the maximum convective cold performance that shall be reported is level 1. 4.6 Contact cold When tested in accordance with 5.6, the thermal resistance properties of the material shall comply with the values given in Table 2. Table 2 — Thermal resistance values Performance level Thermal resistance R in m2 K/W 1 0,025 ≤ R < 0,050 2 0,050 ≤ R < 0,100 3 0,100 ≤ R < 0,150 4 0,150 ≤ R

For a contact cold performance level of 2 to 4, the product shall record at least level 2 in abrasion and tear resistance according to EN 388, otherwise the maximum contact cold performance that shall 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 carried 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 simultaneously, 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 glove's manufacturer.  The number 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 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 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 flexibility 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 the 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 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 temperature 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 temperature, which is at least 20 °C lower. 5.5.2 Apparatu
