8、on ofBS7659 has been prepared under the direction of the Consumer and Contract Goods Standards Policy Committee. It supersedesBS7659:1993, which is withdrawn. This revision specifies the location of some of the interstices for drainage purposes and also includes ventilation and drainage requirements

9、 for the additional internal front piece present in certain muzzle designs. The purpose of this British Standard is to provide designers, manufacturers, retailers, consumers and other interested parties with requirements for dog muzzles that should minimize the risks to humans of serious injury caus

10、ed by dog attacks. It is emphasized that dog muzzles conforming to this British Standard will not prevent all injuries occurring, for example damage to fingers placed through a muzzle. For this reason, and for the welfare of the dog, it is essential that a muzzled dog is supervised at all times by a

11、 responsible person. If a dog needs to be muzzled to comply with the Dangerous Dogs Act19911 then it needs to be under the control of a person who is not less than16 years old. This British Standard takes into account the welfare of dogs. A dog can die if unable to open its mouth to pant and drink,

12、or if vomit cannot drain from the muzzle. Therefore box or sock muzzles are not recommended for general use and should never be used when exercising a dog; they are only suitable for use for a short period of time by qualified personnel. Thus this standard specifies that muzzles consist of a cage en

13、closure that includes a front piece. The mechanical requirements of this standard only assess the ability of muzzles to withstand specific breaking loads; this standard does not cover requirements for the durability of muzzles on individual dogs. Muzzles need to be inspected before use and should ne

14、ver be used if damaged. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages

15、This document comprises a front cover, an inside front cover, pages i and ii, pages1 to 6, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS76

16、59:1994 BSI 10-1999 1 Introduction This British Standard has been designed to minimize the effect of serious injury to humans or animals caused by dog attacks and to accommodate the welfare of the dog. However, muzzles that meet the requirements of this standard will not prevent all injuries occurri

17、ng, for example damage to fingers placed through a muzzle. For this reason, and for the welfare of the dog, it is essential that a muzzled dog is supervised at all times by a responsible person. If a dog needs to be muzzled to comply with the Dangerous Dogs Act19911 then it needs to be under the con

18、trol of a person who is not less than16years old. 1 Scope This British Standard specifies performance and marking requirements for lattice design cage enclosure dog muzzles for general use, for example when exercising a dog. This standard also makes recommendations for the fitting, use and care of d

19、og muzzles and includes methods of test for performance requirements. NOTECorrectly fitted lattice design cage enclosure dog muzzles allow a dog to open its mouth to pant and drink and allow vomit to drain from the muzzle; thus they should not adversely affect the welfare of the dog. 2 Informative r

20、eferences This British Standard refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definitions For the purposes of

21、this British Standard, the following definitions apply. 3.1 lattice cage enclosure a device that encloses the muzzle of the dog ventrally, dorsally and laterally 3.2 interstice a hole in a sheet of material or an intervening space between the bars of a lattice cage enclosure in which the bars are to

22、uching and permanently fixed to each other 3.3 slip lead or choke collar a collar or lead that tightens around the dogs neck when tension is applied and slackens when the tension is released 3.4 stop the point between a dogs eyes where the nose meets the skull (seeFigure 1) 4 Design 4.1 Muzzles shal

23、l consist of a lattice design cage enclosure and shall include a front piece and adjustable straps to fit the muzzle to the dogs head (seeFigure 2). 4.2 Muzzles shall be provided with an attachment for securing the muzzle to the dogs collar at the top of the neck (seeFigure 2). If the muzzle incorpo

24、rates a dog collar, then the collar shall not be a slip lead or choke collar. 4.3 Muzzles designed for short-nosed dogs, for example boxers, shall include an adjustable strap from the bridge of the muzzle to the neck strap (seeFigure 2). NOTE 1Leather or textile lattice design cage enclosure muzzles

25、 should contain a metal reinforcing strip across the front piece (seeFigure 2), in the vertical (i.e.dorso-ventral) plane, to prevent the dog being able to get the muzzle in its mouth. Muzzles of materials other than leather or textile should have a front piece which is sufficiently rigid to prevent

26、 the dog being able to get the muzzle in its mouth. NOTE 2All fasteners should be constructed to prevent unintended release. 5 Ventilation and drainage 5.1 At least50% of the surface area of the lattice cage enclosure shall consist of interstices that are not obstructed by any other components of th

27、e muzzle, such as inner straps. At least50% of the interstices shall be in the lower, i.e.ventral, half of the lattice cage enclosure in order to allow free drainage of secretions or vomit. 5.2 At least50% of the interstices shall have a surface area greater than100mm 2and a minimum dimension, in an

28、y direction, of5mm. At least50% of the interstices in the lower, i.e.ventral, half of the lattice cage enclosure shall have a surface area greater than100mm 2and a minimum dimension, in any direction, of5mm. 5.3 If there is an additional internal front piece, then at least50% of its surface area sha

29、ll consist of interstices and at least50% of these interstices shall be in the lower, i.e.ventral, half of the additional internal front piece. The additional internal front piece shall also conform to5.2. NOTEAdditional internal front pieces do not have to conform toclause6.2 BSI 10-1999 BS7659:199

31、shall remain intact and shall show no visible sign of permanent damage when viewed by normal or corrected vision. The tensile loads applied in Annex A shall be at least1.75times the body weight, in kilograms, of the dog for which the muzzle is suitable see7.1 and7.2 b). 7 Marking 7.1 The number and

32、date of this British Standard, i.e.BS7659:1994 1)and the maximum body weight, in kilograms, of the dog for which the muzzle is suitable (seeclause6), shall be legibly marked on each muzzle at point of sale. NOTEIt is desirable that the number and date of this British Standard and the maximum body we

33、ight, in kilograms, of the dog for which the muzzle is suitable be permanently marked on the muzzle. 7.2 The following information shall be provided by the manufacturer in a leaflet that shall be attached to the muzzle or, if the muzzle is packaged, on, or enclosed in, the packaging: a) the number a

34、nd date of this British Standard, i.e.BS7659:1994 1) ; b) the maximum body weight, in kilograms, of the dog for which the muzzle is suitable (seeclause6); c) the size and type of dog for which the muzzle is intended and whether or not the muzzle is unsuitable for short-nosed or flat-nosed breeds of

35、dogs such as Pekingese and boxer; d) whether or not the muzzle, when worn by the type of dog for which it is intended, permits that dog to drink; NOTEThe information in a) to d) of7.2 should be clearly visible to the purchaser. e) the muzzle manufacturers or suppliers name and address; f) the follow

36、ing warning: “WARNING Inspect the muzzle before and after use and do not use if damaged”; g) the manufacturers cleaning instructions; h) information on fitting, use and care of muzzles which shall include the information given inAnnex B. 1) MarkingBS7659:1994 on or in relation to a product represent

37、s a manufacturers declaration of conformity, i.e.a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be confused with third party certification of conformit

38、y, which may also be desirable.4 BSI 10-1999 BS7659:1994 Annex A (normative) Method of test for breaking strength A.1 Principle An increasing tensile load is applied to the complete muzzle and to component parts of the muzzle. If the muzzle fails, the load at failure is recorded in kilograms and the

39、 mechanism of failure described. Any additional detachable front piece is removed and discarded prior to the tests described inA.3. NOTEA failure includes a break or tear in the material of construction, yield and flow of plastics, the breakage of a fastener, the opening of a fastener, the failure o

40、f a rivet or stitching, etc. A.2 Apparatus A.2.1 Suitable tensile test machine, capable of applying loads at a cross-head speed of95mm/min to125mm/min and of recording the applied load. A.2.2 Abrasive paper, for insertion between the test specimen and jaws of the tensile test machine to prevent slip

41、page of the specimen when the tensile load is applied. A.3 Procedure A.3.1 Remove any detachable internal front piecefrom the muzzle. Clamp each of the two side-arms/straps in each of the two jaws of the tensile test machine, having removed any straps that could restrain the muzzle during test so th

42、at muzzle-to-strap joins are included in the test. Apply the increasing tensile load across the opening of the muzzle (seeFigure 2) at a cross-head speed of95mm/min to125mm/min. Record whether or not the muzzle has failed (seenote toA.1) and if the muzzle has failed record the load at failure and de

43、scribe the mechanism of failure. NOTEA muzzle-to-strap join could consist of leather riveted or stitched to leather, leather riveted to plastics, or textile looped through plastics, etc. A.3.2 Cut each strap and fastener assembly (seenote) from the muzzle allowing a sufficient length of strap to ena

44、ble each strap and fastener specimen to be clamped into the tensile test machine so that each complete assembly can be tested. Apply the increasing tensile load to the ends of each strap and fastener assembly at a cross-head speed of95mm/min to125mm/min. Record whether or not the specimen has failed

45、 and if the specimen has failed record the load at failure and describe the mechanism of failure for each specimen. NOTEExamples of a complete strap and fastener assembly are given below: a) stitched strap/quick release fastener/stitched strap; b) riveted strap/metal buckle/strap. A.3.3 Take a right

46、-angled test specimen from the lattice structure (seeFigure A.1) excluding any detachable front piece. Apply the increasing tensile load to the ends of the right-angled test specimen, at a cross-head speed of95mm/min to125mm/min, so that it tends to straighten the test specimen. Record whether or no

47、t the specimen has failed and if the specimen has failed record the load at failure and describe the mechanism of failure. If the lattice structure contains no right-angled junctions, the test specimen shall include the junction that has an acute angle closest to90 . Figure A.1 Direction of applied

48、tensile force on angled junctions from lattice structuresBS7659:1994 BSI 10-1999 5 A.3.4 Excluding the join between the muzzle and any detachable front piece, if a muzzle design contains riveted, stitched or other types of join not covered by the tests described inA.3.2 andA.3.3, cut a test specimen

49、 that encompasses the join and apply the increasing tensile load, at a cross-head speed of95mm/min to125mm/min, across the join. Record whether or not the specimen has failed and if the specimen has failed record the load at failure and describe the mechanism of failure. A.3.5 Cut from the muzzle the attachment that secures the muzzle to the dogs collar, allowing a sufficient length of strap at the cut end to enable it to be clamped into the tensile test machine. Clamp the cut end into the machine and, through the part through which the collar
