After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the National Associa

15、tions and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2006, and conflicting national standard

EN 4111:20064 1 Scope This standard specifies the requirements which must be met by hand-operated splined wrenches and sockets for aerospace applications. 2 Normative references The foll

19、owing referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 4156, Straight cylindrical involute splines Metric mo

20、dule, side fit Generalities, dimensions and inspection. ISO 6508 (all parts), Metallic materials Rockwell hardness test. EN 9133, Aerospace series Quality management systems Qualification procedure for aerospace standard parts. 3 Terms and definitions For the purposes of this standard, the following

21、 terms and definitions apply. 3.1 batch a batch consists of wrenches or sockets of the same types and of the same materials defined by the same standard 4 Required characteristics 4.1 Materials The materials shall meet the required characteristics specified in the product standard. 4.2 Physical char

22、acteristics 4.2.1 Surface condition/appearance The hand-operated wrenches or sockets shall be free from pitting, deposits, forging flashes, cracks, splits, burrs and other defects liable to impair their characteristics and their endurance and to cause injury to operators. 4.2.2 Surface coating The s

23、urface coating shall be that laid down in the product standard. 4.2.3 Characteristics of the inner profile of the splines All of the splines shall be free from burrs and rough spots. The surface roughness is specified in the product standard. EN 4111:20065 4.3 Mechanical characteristics The strength

24、 and endurance of the various types of wrench are tested by torque tests, the procedures for which are described in Clause 5. At the end of the strength and endurance test, the wrenches or sockets shall not exhibit deterioration or distortion as defined below: The tips of the splines shall not exhib

25、it rounding or fretting and shall be in accordance with the characteristics described in 4.2.3; The wrench or socket shall be free from cracks; The general surface condition shall be in accordance with the requirements of 4.2.1; Distortion of more than 0,05 mm of the outer diameter of the sockets an

26、d wrench heads; The surface coating shall show no significant sign of deterioration or flaking; Permanent distortion of the wrench handle of more than 5; A Rockwell hardness test (ISO 6508) shall demonstrate values in accordance with the values indicated in the product standard. 4.4 Dimensions and t

27、olerances The dimensions and tolerances shall be in accordance with requirements of the product standard. 5 Test methods 5.1 Test equipment The wrenches or sockets are fitted on a splined test mandrel. The mandrel dimensions for a relevant wrench shall be based on the maximum corresponding values fo

28、r an external 45 pressure angle side fit root radius 6H spline to ISO 4156, and a hardness of 60 HRC. 5.2 Test on splined wrenches and sockets The wrenches or sockets shall be fully engaged on the mandrel; during the test, the wrench shall be moved smoothly without knocks and jerks. The load shall b

29、e applied as far away as possible on the arm of the wrench or at the driving square of the sockets, perpendicularly to the axis, continuously and progressively up to the torque value appropriate to the wrench under test. 5.3 Conduct of the test On each wrench or socket tested, carry out a cycle of 5

30、00 applications, at maximum rate of 60 per minute, at the endurance torque indicated in Table 1. At the end of each 100 applications, apply the resistance torque, which is equivalent to 1,5 times the endurance torque indicated in Table 1, and move the wrench 1/8 of a turn. In the case of double-ende

31、d wrenches, each end shall be tested.

Qualification tests specified in this document shall be applied to each type and each dimensional combination of wrench of socket in accordance with Tables 2 and 3. Some or all of these te

33、sts may also be used for acceptance of function where a more comprehensive test proves necessary. 6.2 Acceptance The aim of the acceptance tests is to check, as simply as possible, that wrenches or sockets from different batches satisfy the requirements of this standard. The acceptance tests shall b

34、e conducted on wrenches or sockets chosen at random from different production batches in accordance with Tables 4 and 5. 7 Marking/packaging 7.1 Marking The marking is specified in the product standard.
