BS EN 407-2004 pdf download.Protective gloves against thermal risks ( heat and / or fire ).
This BS EN 407 specifies requirements, test methods, information to be supplied and marking for protective gloves against heat and/or fire. It should be used for all gloves which protect the hands against heat and/or flames in one or more of the following forms: fire, contact heat, convective heat, radiant heat, small splashes or large quantities of molten metal.
This standard is only applicable in conjunction with EN420.
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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
after flame time
time in seconds from the removal of the ignition source until the extinction of the flame in the test specimen
3.2
after glow time
3.4
dripping
detachment of molten droplets during the melting process
4 General requirements
4.1 General
The protective gloves according to this standard shall meet all the applicable requirements of EN 420.
4.2 Sizes
The gloves shall correspond to the relevant requirements of EN 420. Unless otherwise requested, protective gloves of performance levels 3 and 4 in all tests described in 5.1 to 5.6. shall be manufactured so that they can easily be removed in case of emergency. There is no test method for industrial protective gloves. Annex B gives an example of a test method and requirement applicable to fire-fighters gloves.
4.3 Abrasion
Using the test method 6.1 the material of the protective gloves shall correspond to at least performance level 1
of the relevant clause in EN 388.
4.4 Tear resistance
Using the test method 6.2 the material of the protective gloves shall correspond to at least performance level 1 of the relevant clause in EN 388.
5 Thermal performance
For each of the following test methods the defined performance level depends upon the intended field of application of the glove. Only the tests which are relevant to the risks in the intended end-use application shall be carried out.
The test is failed if steel droplets remain stuck to the specimen, or the specimen ignites or is punctured. This test only applies to molten iron. Other metals shall be tested as required. The corresponding test results shall be given on the information supplied by the manufacturer (clause 8), 6 Test methods
For multilayered gloves, the tests are carried out simultaneously on all layers, even if these in some circumstances are no longer connected, This applies to test methods described in 6.3, 6.4, 6.5, 6.6, 6.7, and
6.8.
6.1 Abrasion
Test according to EN 388.
6.2 Tear resistance
Test according to EN 388.
6.3 Burning behaviour
Test method according to EN ISO 6941 with tue toilowing modification:
— the glove is mounted vertically so that the point A (Figure 1) is at the mid point of the lower edge.BS EN 407-2004 pdf download.
