EN 13411-1:2002 (E) 4 Introduction This European Standard has been prepared to provide a means of conforming with the essential safety requirements of the Machinery Directive and associated EFTA regulations. Purchasers ordering
20、to this standard are advised to specify in their purchasing contract that the supplier operates a certified quality assurance system applicable to the relevant part of this standard (e.g. EN ISO 9001) to ensure themselves that products claiming to comply consistently achieve the required level of qu
21、ality. While producing this standard it was assumed that negotiation occurs between the manufacturer and the user to decide whether the thimble shall have a pointed or truncated end and whether zinc coating is required. 1 Scope This European Standard specifies the minimum requirements for non welded
22、 general purpose steel thimbles produced from plate having dimensions in accordance with Figure 1. The thimbles are intended to be used in slings made with six or eight strand steel wire ropes from 8 mm to 60 mm diameter complying with EN 12385-4. Reeving thimbles and solid thimbles are not covered
23、by this standard. The hazards covered by this standard are identified in clause 4. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publica
24、tions are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amen
25、dments). EN 292-2:1991/A1:1995, Safety of machinery - Basic concepts, general principles for design - Part 2: Technical principles and specifications (Amendment 1:1995).

28、ich the thimble has been primarily designed 4 Hazards This clause contains the hazards and hazardous situations, as far as they are dealt with in this European Standard, identified by risk assessment significant for this type of machinery and which requires action to eliminate or reduce risk. Accide
29、ntal release of a load, or release of a load due to failure of a steel thimble puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. In order to provide the necessary strength of steel thimble this standard gives requirements for the design, manuf
30、acture and testing to ensure the specified levels of performance are met. Errors in the fitting of accessories can also lead to premature failure and this standard contains dimensional requirements to allow correct fit. Table 1 contains all the hazards, which require action to reduce risk identified
31、 by risk assessment as being specific and significant for general purpose steel thimbles. Table 1 - Hazards and associated requirements Hazards identified in annex A of EN 1050:1996 Relevant clause of annex A of EN 292-2:1991/A1:1995 Relevant clause/subclause of this standard 1Mechanical hazard1.3.2

33、nforming to EN 10025. EN 13411-1:2002 (E) 6 NOTE If the thimble is surface coated with zinc, the amount should be at least 120 g/m2 and should be applied in accordance with ISO 1461. 5.3 Construction Thimbles shall be free from any flaws or defects. NOTE 1 A small gap at the joint may be tolerated.
34、NOTE 2 There is no requirement regarding whether thimbles should be pointed or not (see Figure 1), and this should be subjected to agreement between the purchaser and the manufacturer, see introduction. Thimbles shall be capable of being opened and closed once without the application of heat, wide e
35、nough to allow insertion of a component of 1,5 times the nominal rope diameter. 5.4 Type test A type test shall demonstrate that the design, material and method of manufacture of the thimble having dimensions meeting the requirements of this standard can withstand the maximum loading conditions like
36、ly to be imposed upon it under normal conditions of use. Any change, for example in the material specification, method of manufacture or critical dimensions, likely to effect the safety of the thimble, shall require that the type test in 6.1.2 be undertaken on the modified thimble. After testing in
37、accordance with 6.1.2 and with the load removed, any permanent reduction measured in dimension 1 of Figure 1 shall not exceed 15 % of its original value.

38、1 Type test 6.1.1 Apparatus 6.1.1.1 Rope The rope diameter shall be the same as the nominal size of the thimble. The rope construction shall be one from Table 6, 7, or 8 of EN 12385-4:2002 with a steel core. The rope grade shall be 1770. 6.1.1.2 Pin The load shall be applied to the thimble through a
39、 pin having a diameter of 1,5 d. 6.1.2 Method The method of test shall be in accordance with 6.4.1 of EN 12385-1:2002. Carry out two tests on each size of thimble of each design, material and method of manufacture. Fit the thimble to a rope of the size specified in 6.1.1.1 and load it axially to 27
40、% of the minimum breaking force of the rope as given in EN 12385-4:2002. After release of the test load measure dimension 1 of Figure 1 for any permanent reduction. The reduction shall not be greater than that specified in 5.4. If any one thimble fails to pass, test a further two thimbles of the sam
41、e size, design, material and method of manufacture. If these pass then the thimbles shall be deemed to have passed the type test. If one or both fail the re-test or if both thimbles fail the original test, the thimbles shall be deemed to have failed the type test. 6.2 Dimensions The linear dimension
42、s of the thimble shall be measured with an instrument accurate to 0,1 mm and having a resolution of 0,01 mm. The measured dimension shall lie within the range specified in Figure 1. The angle shall be measured with an instrument accurate to 5 with a resolution of 1. 6.3 Material The suppliers record
43、s shall be used to verify the material used. 6.4 Construction Thimbles shall be visually inspected for surface defects liable to injure the user or damage the rope. EN 13411-1:2002 (E) 8 7 Certificate The manufacturer or supplier shall, on request, provide a certificate giving the following informat
44、ion: a) a statement of conformance to this European Standard; b) name and address of manufacturer; c) nominal size of thimble (rope diameter); d) a means of referencing the certificate to the thimble.
