A non exhaustive list of specific standards dealing with hazards is given in the Bibliography SIST EN 420:2003+A1:2010



EN 420:2003+A1:2009 (E) 7 3.7 level of performance number that designates a particular category or range of performance by which the results of testing can be graded The level of performance is determined by the result of the corresponding test as described in the specific standards referred to in the Bibliography. A high level number corresponds to a high level of performance. Levels of performance are based upon the results of laboratory tests, which do not necessarily reflect actual conditions in the workplace. 4 General requirements 4.1 Glove design and construction — General The protective glove shall be designed and manufactured so that in the foreseeable conditions of use for which it is intended, the user can perform the hazard related activity normally whilst enjoying appropriate protection at the highest possible level. If required, the glove shall be designed to minimize the time needed for putting on and taking off. When the glove construction includes seams, the material and strength of the seams shall be such that the overall performance of the glove is not significantly decreased. Where relevant, test methods and requirements are specified in the specific standards listed in the Bibliography. 4.2 Resistance of glove materials to water penetration For glove materials where resistance to water penetration is required (according to the intended use of the glove), the appropriate test methods shall be used:  For leather gloves: 5.12 of EN 344-1:1992. The results shall be reported according to Table 1;  Alternative test method which is more appropriate to textile materials: EN 20811. The results shall be reported as a pressure in Pascal as required in EN 20811. NOTE 1 There is no known correlation between results obtained through these different test methods. NOTE 2 These tests are not suitable to classify these gloves as waterproof. Table 1 — Levels of performance — resistance to water penetration according to 5.12 of

EN 420:2003+A1:2009 (E) 8 4.3 Innocuousness of protective gloves 4.3.1 General Protective gloves shall be designed and manufactured to provide protection when used according to the manufacturer's instructions, without harm to the user. Glove materials, degradation products, incorporated substances, seams and edges and particularly those parts of the glove in close contact with the user shall not adversely affect the user's health and hygiene. The manufacturer or his authorized representative shall name all the substances contained in the glove which are known to cause allergies (see 7.3.8). 4.3.2 Determination of pH Value The pH value for all gloves shall be greater than 3,5 and less than 9,5. Determination of pH shall be according to EN ISO 4045 for leather gloves, and EN 1413 for other materials. Following amendments shall apply:  the test piece shall be cut out from the palm area of the glove. If other parts of the glove are made of different materials, then each material shall be tested separately;  if gloves are made of more than one layer, all layers shall be tested together;  if the sample contains leather, then EN ISO 4045 shall be used;  subclause 8.4 of EN ISO 4045:1998 does not apply. 4.3.3 !!!!Determination of chromium VI content The quantity of Chromium VI in gloves containing leather shall not exceed 3,0 mg/kg when determined according to the test method described in EN ISO 17075:2007.
Depending on the measured Chromium VI content, the test report shall indicate:  that the Chromium VI content is not in excess of 3,0 mg/kg, or  that Chromium VI content is in excess of 3,0 mg/kg and the value that has been determined in mg/kg. If the glove includes different types of leather, whether in contact with the skin or not, each leather type shall be tested separately and comply with the above requirement. At least two samples shall be taken from different gloves for each leather type." 4.3.4 Determination of extractable protein content Natural rubber gloves shall be submitted to requirements stated in EN 455-3 on extractable protein content. NOTE This method has not yet been validated for gloves other than medical gloves for single use. 4.4 Cleaning All tests required in this standard as well as in the standards for protective gloves shall be performed on unused gloves unless otherwise specified. If care instructions are provided (see 7.3.10), the relevant tests of the specific standards (see Bibliography) shall be performed on the gloves, before and after they have been subjected to the maximum recommended number of cleaning cycles. SIST EN 420:2003+A1:2010



EN 420:2003+A1:2009 (E) 9 The levels of performance shall not be negatively affected throughout the recommended number of cycles. 4.5 Electrostatic properties If required, the electrostatic properties shall be tested according to the test method described in the relevant standard EN 1149-1 or EN 1149-2 or EN 1149-3. The test result shall be reported in the information supplied by the manufacturer accompanied by the information stated in 7.3.11. Electrostatic pictograms shall not be used for this property. NOTE These tests are designed for garments and have not been validated for gloves. Some interlaboratory trials have shown significant discrepancies in test results for one of the methods. It is thus essential to give comprehensive information about the test parameters used along with any test result. 5 Comfort and efficiency 5.1 Sizing 5.1.1 Sizes and measurement of hands Two primary measurements are taken according to 6.1:  hand circumference;  hand length (distance between the wrist and the tip of the middle finger). Six sizes of hands are defined in Table 2, according to anthropomorphic surveys conducted in different countries. Half sizes can be derived by interpolation between full sizes. Any smaller and larger sizes can be derived by extrapolation of the data in Tables 2 and 3. SIST EN 420:2003+A1:2010

5.1.2 Sizes and measurements of glove Sizes of gloves are defined with respect to the sizes of the hands they are to fit. Six sizes are defined in Table 3. The minimum length of glove for half sizes shall be the one of the next higher full size. Actual measurements of gloves shall be determined by the manufacturer taking into account the behaviour of the glove material and intended use.

Actual measurements of gloves shall be determined, taking into account the behaviour of the glove material and intended use. 5.1.3 Gloves for special applications It is possible that the length of gloves designed for special applications may not conform to the values of Table 3. For such gloves, the manufacturer shall demonstrate that they are "fit for special purpose" by clearly stating in the instructions for use (7.3) the intended application(s) and the reason why the gloves do not conform to Table 3. SIST EN 420:2003+A1:2010



EN 420:2003+A1:2009 (E) 11 5.2 Dexterity A glove should allow as much dexterity as possible given its purpose. Dexterity is related to numerous factors e. g. thickness of glove material, its elasticity, its deformability.
If required, finger dexterity shall be tested according to the test method in 6.2. The performances shall be graded according to Table 4 hereafter. Table 1 — Levels of performance - finger dexterity test Level of performance Smallest diameter of pin fulfilling test conditions mm 1 2 3 4 5 11

5.3 Water vapour transmission and absorption 5.3.1 Where practicable, protective gloves shall allow water vapour transmission. If required, gloves shall have a water vapour transmission of at least 5 mg/(cm² ⋅ h) when tested according to 6.3. 5.3.2 Where the protection characteristics of the glove inhibits or excludes water vapour transmission, then the glove shall be designed to reduce the effect of perspiration as much as possible. If required, gloves shall have a water vapour absorption of at least 8 mg/cm² for 8 h when tested according to 6.4. 6 Test procedures 6.1 Hand and glove measurement and dimensions 6.1.1 The circumference of the hand is measured with a tape, 20 mm from the crotch between thumb and index finger (see Figure 2). 6.1.2 Length of hand is as shown on Figure 2. 6.1.3 Measure the length by freely suspending the glove with the middle finger on a vertical graduated rule having a rounded tip so as to fit the shape of the finger tip of the glove. Remove wrinkles and folds without stretching the glove. Record the minimum measured length to the nearest millimeter. NOTE For greater ease of measurement, the rule can be angled backwards slightly so that the glove is in contact with the rule. 6.1.4 If the gloves are stretchable, the dimensions shall be measured with the sample in the unstretched state or by placing it on the hand of a person with appropriate size.
