5、Part 1 is intended to serve as a general document and deals with features that are likely to be common requirements for most tools. Subsequent Parts of this standard will cover details of the tools prepared as separate documents and may call up some or all of the requirements and tests of this Part

6、1, deleting such as are not applicable and adding others when necessary. Among additional requirements to be specified in the detail tool specification may be the following: type of frame; dimensions and other particulars of dies, indentors, etc; methods of, and devices for, the location of componen

7、ts during the crimping operation; test requirements, including details of test pieces; and/or die gauging methods; part numbering systems, including additional marking requirements; ordering information, including number of tool specification, tool and die references, as applicable.

For dated references, subsequent amendments to, or revisions of, any of these publications apply to this Euro

10、pean Standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. 3 Definitions For the purposes of this European Standard the general electrical and telecommunication terms anddefinitions given in the appropriate

11、Parts of IEC50(581) apply. In addition, the following definitions apply: 3.1 type tests tests made to show that hand crimping tools initially meet the requirements of this Part 1 and the relevant Part2of this Standard; to be repeated at prescribed intervals thereafter 3.2 production tests selected t

12、ests repeated at prescribed intervals on samples from current production to confirm that the quality and performance of the product continues to conform to the requirements of this Part 1 and the relevant Part2of this Standard HD 323.2.52 S1 1987 Basic environmental testing procedures Part 2: Tests

14、ning with the closing of the handles and ending when, after completion of the actual crimping operation, the handles have returned to the fully open position 3.4 full closure mechanism a mechanical device ensuring that once the closing of the handles has commenced, the handles can only return to the

15、 fully open position by completion of the closure of the tool 3.5 test piece a device specifically designed to simulate during tests the mechanical characteristics of a component to be crimped 3.6 crimping dies the component pairs or set of component parts of a crimping tool which, when applied to a

16、 terminal end, contact or other connecting device or portion thereof, deforms it over an electrical conductor or the insulation or braid to make a permanent electrical connection. Crimping dies may be integral with a tool or removable and interchangeable 3.7 hexagon crimp 1) a crimped joint formed b

17、y the action of crimping dies shaped to impart a hexagonal form 3.8 indentor a substantially wedge-shaped component part or set of component parts of a crimping tool which through the action of the tool deforms a contact crimping barrel enveloping an electrical conductor to form a crimped joint 3.9

18、indent crimp 1) a crimped joint formed by the action of an indentor or set of indentors 3.10 locator a device fitted to a crimping die to serve as an abutment to locate the terminal end, contact or connecting device during the crimping operation 3.11 positioner a device fitted to a crimping tool for

19、 correctly positioning the item to be crimped prior to and during the crimping operation 3.12 turret a device fitted to a crimping tool containing more than one positioner which may be selectively brought into use without removing the turret 3.13 open throat tool a tool which allows both axial and l

20、ateral access to the termination barrel prior to and after the crimping operation 1) Other crimping configurations may be adopted in the relevant Part2 of this Standard.EN50109-1:1995 BSI 03-2000 5 4 Requirements 4.1 Materials Hand crimping tools shall be manufactured from suitable materials which,

21、whenever practicable, shall comply with the requirements of appropriate European Standards. 4.2 Component parts Parts of hand crimping tools shall be resistant to corrosion and, where necessary, be subjected to an appropriate protective treatment. 4.3 Tool operation Tools shall operate and correctly

22、 form the crimp without damaging the component to be crimped. On completion of the crimp, the handles and dies or indentors shall automatically return to the fully open position. 4.4 Removable parts Removable parts, such as crimping dies and location devices shall be designed or marked to ensure tha

23、t they can only be fitted to the tool in the correct manner. 4.5 Clearance and access Tools shall provide sufficient clearance around the crimp area to permit insertion and withdrawal of components to be crimped without the use of additional tooling. 4.6 Location Means shall be provided for the prop

24、er location of components during the crimping operation. 4.7 Alignment Tools, dies and indentors shall be designed so that the alignment between moving parts meets the requirements of the relevant Part2of this Standard. 4.8 Full closure mechanism Tools shall incorporate a full closure mechanism. 4.9

25、 Emergency release If an emergency release is fitted, it shall be so designed as to require specialist intervention before the tool is returned to normal use. 4.10 Adjustment The tool design shall be such that no adjustment can be made other than permitted by the relevant Part2of this Standard. 4.11

26、 Jamming Tools shall operate freely and without any part jamming so as to impair function during normal operation. 4.12 Workmanship Tools and all parts shall be made and finished so as to be free from defects that could affect performance. There shall be no sharp edges, burrs or other defects of pot

27、ential hazard to the operator. 4.13 Code marking The completed joint should, where practicable, be marked in accordance with the code prescribed in the relevant Part 2 of this standard, to identify the size of the crimping tool or die. Such marking, which shallbe applied during the formation of the

28、crimp, may be embossed or indented. 4.14 Lubrication Any lubricants employed for ensuring the correct operation of the tool, shall not contaminate the component parts of the connectors. 5 Classification and designation The classification and designation of crimping tools, their dies and any associat

29、ed accessories are described in the relevant Part 2 of this Standard.EN50109-1:1995 6 BSI 03-2000 5.1 Tool marking Tools shall be marked to display the following information: identification of manufacturer or supplier; part or reference number; serial number; such other markings (which may be extend

30、ed to dies and location devices intended for use with the tools) as may be required by the relevant Part 2 of this Standard. NOTEWhen drafting additional Parts 2, care should be taken that reference and marking systems are compatible, bearing in mind that the same tool may be used under more than on

32、ntenance and inspection procedures. Specific recommendations may also be included in relevant Parts 2 of this Standard. The tool manufacturer shall supply the following: full operating instructions with each tool; test pieces and their associated gauges if required by the user. These shall be no les

33、s onerous than those specified in the relevant Part2; information on supply of user control gauges, if required by the user. 6 Tests and test methods 6.1 Test requirements Tests in accordance with 6.2 shall be made to prove compliance with the requirements of this European Standard. The tests are in

34、tended as type tests and shall be repeated at intervals of not greater than six years. Selected tests for production and sampling purposes shall be repeated at intervals as prescribed in6.2,orin the relevant Part2, on samples from current production to confirm that the quality and performance of the

35、 product continues to conform to the requirements of this Part1and the relevant Part2of this standard. 6.2 Type tests 6.2.1 Sample size Unless otherwise specified in the relevant Part2, three specimen tools and one set of piece parts shall be submitted to the tests in this clause. The tools shall be complete and ready for use in accordance with the relevant Part2. Where a tool, or tool series, covers a range of die sizes, the tests conducted shall include the largest size and the smallest size prescribed in the relevant Part2of this standard.
