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.

a This code is a conventional designation of hand size corresponding to the hand circumference expressed in inches.
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.

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.
