11、ental impact by cricket balls. Batsmen are particularly exposed to balls coming off the pitch at unexpected angles. The level of protection required depends on the skill and strength of the player and of the opposing team. This British Standard is divided into five parts as follows: Part 1: General

12、requirements; Part 2: Genital protectors; Part 3: Leg protectors for batsmen, wicket-keepers and fielders and thigh, arm and chest protectors for batsmen; Part 4: Gloves for batsmen; Part 5: Gloves for wicket keepers. Batsmens hands are exposed to impacts by cricket balls when they are holding their

13、 bat. The impacts are all unintentional. A ball hitting a glove and going on to the wicket or being caught gets the batsman out. They therefore do not want gloves that are larger than is essential. Some bowlers may be tempted to bowl in such a way that glove impacts are more likely. Balls coming off

14、 the pitch and rising unexpectedly are a particular problem to batsmen. In causing injuries the velocity of the ball is highly significant, while the movement of the bat handle towards the ball contributes to the severity of the impact particularly as the hand is most frequently injured by being bet

15、ween the ball and the bat handle. Batting gloves do not prevent all hand injuries, but should reduce their severity. Bruising is much more common than fractures. Hand injuries cause more days of playing to be lost than all other ball impact injuries combined. An analysis of reported fractures in fir

16、st class cricket showed concentrations of fractures to the thumb and first finger of the bottom hand, and to the fourth finger of the top hand. Smaller numbers of fractures occurred to the second finger of the bottom hand and first finger of the top hand. It is probable some fractures are caused by

17、lateral impacts on the digits which are exposed in the areas where most fractures occur and where padding on the gloves has been frequently thinner than on the backs of the digits. Batsmen are particularly concerned about the comfort and fit of their gloves because their aim is to score runs off goo

18、d strokes. Batsmen are not able to predict what level of protection they will need or to accurately assess the protection that will be provided by a glove. Their choice of glove is therefore guided by comfort and fit and the reputation of the gloves. Four performance levels are described in BS 6183-

19、1:2000, 3.1.4 note 1. Level 4 is the appropriate level of protection for batsmen in first class cricket with a history of finger fractures and batsmen who are perhaps particularly concerned to protect their bowling hand. 1 Scope This part of this British Standard gives requirements and test methods

23、4:2001 2 BSI 03-2001 3 Definitions For the purposes of this part of this British Standard, the definitions given in BS 6183-1 and the following apply. 3.1 lower hand hand of a batsman that is closest to the blade of the cricket bat when the bat is held in batting NOTE This is the right hand of a rig

24、ht-handed player and the left hand of a left-handed player. 3.2 upper hand hand of a batsman that is furthest from the blade of the cricket bat when the bat is held in batting 4 Specific requirements 4.1 General Gloves shall conform to the general requirements for protective equipment for cricketers

25、 specified in BS 6183-1:2000. Except where otherwise specified for a particular test, all sizes of a particular glove shall be subjected to all the tests specified in 4.3 to 4.6, and all sizes shall conform to the requirements for the same performance level. It shall be permissible for each of the t

26、ests specified in 4.2 to be carried out on one sample of the relevant material from each type of glove. 4.2 Innocuousness When tested in accordance with BS EN ISO 4045, leather glove materials shall have a pH of between 3.5 and 9.5 and if the pH is less than 4.0 the difference figure shall be less t

27、han 0.7. When tested in accordance with BS EN 420:1994, 6.1 the chromium (VI) content of leather glove materials shall be less than 10 mg/kg. When tested in accordance with BS EN ISO 11642 the change in colour of any component of multifibre fabric glove material shall be not worse than grey scale ra

28、ting 3. NOTE The extractable protein content of natural rubber components of gloves should be as low as possible. A method for measuring extractable protein in medical gloves is given in BS EN 455-3. Application of this method to other gloves is under consideration. 4.3 Minimum areas of zone protect

29、ion When a cricket bat handle is gripped as in playing, and the gloves examined in accordance with 5.1 the gloves shall provide protection to at least the following areas of the hands: a) lower hand: the backs of digits 1 to 5; the end of digit 1; the medial aspect of the palm and digit 2 (performan

30、ce levels 3 and 4 only); the back of the palm to the wrist; b) upper hand: the backs of digits 2 to 5; the lateral aspect of the palm and digit 5 (performance levels 3 and 4 only); the back of the palm to the wrist. NOTE The gloves are illustrated in Figure 1 and Figure 2.BS 6183-4:2001 BSI 03-2001

31、3 4.4 Gaps between blocks of padding When tested in accordance with 5.2 the test probe shall not make firm contact with the hand in the glove. 4.5 Restraint The gloves shall have a closeness of fit and shall incorporate restraint systems, such that, when tested in accordance with 5.3, they remain se

32、curely on the hands: a) when the bat handle is gripped; b) when the hands are moved as in playing strokes; c) when one hand is removed from the handle as in taking avoiding action or adjusting the grip. 4.6 Impact performance When each type of construction identified in the gloves is tested in accor

33、dance with 5.4 at the impact energy specified in Table 1, the mean of the peak force measurements shall be less than 3 kN and no single value shall exceed 4.5 kN. Table 1 Impact energies for testing batsmens gloves 5 Test methods and procedures 5.1 Examination of zones of protection Batsmens gloves

34、that have been prepared in accordance with BS 6183-1:2000, 5.3 shall be examined with the help of assistants. Assistants shall be selected who have hands of an appropriate size for the gloves being examined. An assistant shall put on a pair of gloves and adopt a batting grip on a cricket bat handle

35、as described in 5.3. The examiner shall record any points within the areas listed in 4.3 where impact protective material is absent, or is of a reduced thickness or is softer. Areas of the zones of protection with different construction shall be recorded or marked on the gloves as a guide for subseq

36、uent impact testing (see 5.4). Gloves of all available sizes shall be examined and variations in the linear dimensions, thickness and density of padding recorded. In particular where padding is thinner or less dense on smaller sizes of glove this shall be recorded. NOTE 1 This is usually true for “s

37、ausage” designs. NOTE 2 This information is needed for selection of gloves for impact testing (see 5.4.4.1).

39、e gloves shall be tested while the gloves are being worn as described in 5.1. The probe for testing gaps shall have an end as shown in Figure 3. The length l 1shall be greater than 20 mm. The width, l 2 , shall be 20 mm 2 mm. The thickness, l 3 , shall be 20 mm 2 mm. The wedge shaped end shall have

40、an angle of 75 2 and a radius of curvature, r, of 2 mm 0.2 mm. The probe shall be made of steel or other hard metal. A system shall be provided such that the probe can be applied to a gap between padding blocks with an increasing force up to 30 N 2 N. NOTE For convenience, the system may be simply a

41、 mass of which the probe is a part. The probe and mass may be lowered vertically into a gap until the whole mass is supported by the glove or the test has been halted. The bat handle shall be supported during the procedure to reduce strain on the assistant. The probe shall be used three times in eac

42、h gap between padding blocks on each size of glove. The probe shall be applied with an increasing force to the gap while the bat handle is firmly gripped, until either the assistant reports that the end of the probe is exerting pressure on their hand through the glove, or a force of 30 N 2 N has bee

43、n reached, whichever occurs first. In tests where the result is not clear-cut a rough wooden spill 1.0 mm 0.5 mm thick trimmed to a width suitable for the gap under test shall be placed at the bottom of the gap. The probe shall be applied with a force of 30 N 2 N and the examiner shall attempt to wi

44、thdraw the spill. If this can be done with minimal force the gap shall be deemed to be acceptable. If the spill is pressed into the glove by the probe and resists being withdrawn, the gap shall be deemed to be unacceptable. The results shall be recorded. 5.3 Restraint testing The examiner, with the

45、help of assistants as in 5.1, shall assess the closeness of fit and restraint system of the gloves. For each test, an assistant shall put on the gloves and adjust them according to the manufacturers instructions. They shall hold a bat as in playing, with their hands close together near the top of th

46、e handle. Crotch 1 of each hand shall be in line and aligned between the outside edge of the bat and the splice of the bat. The assistant shall then make vigorous movements with the bat as in playing strokes. They shall report whether the gloves are secure on their hands or move, whether there is an

47、y difficulty in gripping the bat caused by the gloves, and whether there is discomfort due to seam positions, tightness or excessive looseness. The assistant shall then take one hand at a time off the bat handle, shake the hand vigorously and return it to the bat handle. They shall report whether th

48、e glove has moved or remained in its playing position. The results shall be recorded. 5.4 Impact testing 5.4.1 General Impact testing shall be carried out using the apparatus described in BS 6183-3:2000, 5.3.1. 5.4.2 Anvils 5.4.2.1 Transverse impacts on the digits and the sides of the palm Impacts o

49、n the protective padding on the backs and sides of the digits and on the sides of the palm shall be made on the leg and forearm anvil (anvil A) specified in BS 6183-3:2000, 5.3.2.1. 5.4.2.2 Impacts on the back of the palm and axially on the end of digit 1 of the lower hand The anvil for testing the protective padding on the back of the palm and on the end of digit 1 of the lower hand shall be the same as the knee anvil (anvil B) specified in BS 6183-3:2000, 5.3.2.2 except that the upper surface shall have a ra
