The burner is placed below the glove so that it is in a plane with the vertical middle line of the glove

or the middle finger and is perpendicular to the surface of the glove. The burner is mounted at an

angle of 30° ± 3° to the vertical. The distance between the tip of the burner and the lower edge of the

glove or the middle finger shall be 20 mm ± 2 mm.

For leather gloves and mittens, a metallic rod simulating the finger shall be inserted to ensure that

the material is in contact to the flame and limit the retraction of material during all the test time (see

Figure 2).
The rod shall be rigid. Material and dimensions have no influence on the test.

The after flame time and afterglow time shall be recorded after an ignition time of 10 s (see Table 2).

6.2.3 Test report
The test report shall contain the following information:

prEN 407:2017 (E) 4 European foreword This document (prEN 407:2017) has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN. This document is currently submitted to the CEN Enquiry. This document will supersede EN 407:2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document. oSIST prEN 407:2017

prEN 407:2017 (E) 5 1 Scope This European Standard specifies requirements, test methods, marking and information for protective gloves against heat and/or flame and hands protective equipment against domestic thermal risks. It should be used for all gloves and hands protective equipment which protect the hands or part of the hand against heat and/or flame in one or more of the following forms: flame, contact heat, convective heat, radiant heat, small splashes or large quantities of molten metal. This standard is only applicable in conjunction with EN 420. There are other standards relevant to specific applications, as for example fire-fighting or welding. Product tests may only give performance levels and not protection levels. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

When parts of the glove are made from dissimilar materials, these dissimilar materials shall be tested separately, except if another way is specified in the standard. In those circumstances when the sample size is significantly larger than the particular part of the glove being tested, then the manufacturer shall be requested to supply samples of the appropriate materials. 4.2.2 Sizes The gloves shall correspond to the relevant requirements of EN 420. Unless otherwise requested, protective gloves of performance levels 3 and 4 in 1 of the tests described in 4.2.3.2 to 4.2.3.7 shall be manufactured so that they can easily be removed in case of an emergency. Test shall be performed according to EN 659:2003+A1:2008, 3.15 using the same requirement. The removal test can be carried out only in the dry state if the manufacturer’s information states that the glove is not intended for use in wet conditions. If protection against metal splashes as described in 4.2.3.6 and/or 4.2.3.7 is claimed, the minimal length of the glove shall correspond to the requirements of Table 1.
