18、usively, worn by serving police officers and prison officers whilst they are engaged in operational duties and in training. They are also used by civilians engaged in activities where the risks of attack and assault are similar, e.g. private security personnel, bullion handlers, escorts and couriers
19、. The protective gloves specified in this part of BS 7971 are intended to reduce the risk of injury from mechanical, thermal and chemical hazards. The test methods specified in this part of BS 7971 have been designed to measure the performance of gloves with respect to the protection they can be exp
20、ected to provide against these hazards. However, these tests do not necessarily compare with the conditions to which police officers, prison officers and other users can be exposed in real life situations, where the mechanical, thermal and chemical hazards encountered might be different. 1 Scope Thi
21、s part of BS 7971 specifies performance requirements and test methods for gloves to provide protection against mechanical, thermal and chemical hazards, for use by police and prison officers and others who might be exposed to attack and assault in the course of their duties, for use in operational s
22、ituations and in training. NOTE 1Information and guidance on the use of these gloves is given in Annex A. NOTE 2 Guidance on risk assessment and the selection, care and maintenance of protective clothing and equipment for use in violent situations and in training is given in BS 7971-2. 2 Normative r

The performance level of each type of glove shall be as
29、specified in Table 1. Table 1 Types and performance levels of MTC gloves 4 Construction and performance requirements 4.1 General MTC gloves shall conform to BS EN 420 and to the general requirements for protective clothing and equipment for use in violent situations and in training specified in BS 7

36、e glove is tested in accordance with BS EN 388:1994, 6.4, it shall be at least performance level 2 as specified in BS EN 388:1994, Table 1 (i.e. resistant to a puncture force of 60 N). 4.8 Burning behaviour When a glove is tested in accordance with BS EN 407:1994, 6.3, it shall be at least performan
37、ce level 4 as specified in BS EN 407:1994, Table 1 (i.e. an after flame time of k2 s and an after glow time of k5 s). If the material melts it shall not drip. The seam shall not come apart in the test area after an ignition time of 15 s. 4.9 Convective heat resistance When material from the palm of
38、the glove, and from the back of the glove if applicable (see 5.1), is tested in accordance with BS EN 367:1992, the heat transfer index (HTI) shall be at least 10 s. 4.10 Radiant heat resistance When material from the palm of the glove, and from the back of the glove if applicable (see 5.1), is test

40、dance with BS EN 659:1996, Annex A, the material shall not melt, drip or ignite. 4.12 Impact resistance Material from the back of the glove, from the area between the wrist and the knuckles, and excluding the fingers, shall be tested in accordance with BS EN 13594:2002, 6.8.2, but using one test spe
41、cimen and five impact sites 5 mm apart. The material shall conform to BS EN 13594:2002, 4.13. 4.13 Protection against chemicals Type 2 gloves shall have a penetration index of less than 1 % when tested in accordance with BS EN 368:1993, at (23 2) C and (50 2) % r.h., using the chemicals specified in
42、 BS 7971-1. NOTEIn the case of gloves in which the outer layer is leather the number of test specimens may be reduced to three. 4.14 Water penetration resistance of gloves with a waterproof layer NOTEMTC gloves may incorporate a waterproof layer as an additional feature. For gloves which contain a w
43、aterproof layer, the water penetration resistance of the gloves shall be measured in accordance with BS EN 20811 for textile gloves or BS EN 344-1 for leather gloves. The manufacturer shall supply information with the gloves giving the water penetration resistance value obtained. 5 Test specimens, a
44、nd conditioning and testing conditions 5.1 Test specimens The test specimens for the burning behaviour test (see 4.8) shall comprise whole gloves. Test specimens for the other tests to be carried out on glove materials (see 4.4 to 4.7 and 4.9 to 4.14) shall be either: a) cut from one or more gloves;
45、 or b) specially constructed using identical materials and construction techniques to those used in making the gloves. For MTC gloves with a multilayer construction, the test specimens shall include all the layers, even if, after the test specimen has been cut, the layers are no longer connected to
46、one another. In the case of test specimens for heat resistance tests (see 4.9 and 4.10), if the back of the glove does not contain all the materials used in the palm of the glove, two separate sets of test specimens shall be tested, one set from material from the palm of the glove and one set from m
47、aterial from the back. NOTEIf the back of the glove contains all the same materials as used in the palm, with or without additional materials, heat resistance tests may be carried out on test specimens from the palm of the glove only.

49、tely. If the test specimen size is larger than the area of the particular material in the glove then samples of the relevant materials shall be obtained from the manufacturer. 5.2 Conditioning and testing conditions Before testing, the material or the test specimens, as applicable, shall be conditioned in accordance with the relevant test method standard as given in Clause 4.
