13、ards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International orga

14、nizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its

15、further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/dire

16、ctives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the

32、erature of shackle materials shall satisfy the requirements of related certification organizations, such as classification societies.5.2 Forging and heat treatment5.2.1 Shackle bodies need to be forged with seamless solid blanks, and two pinholes shall be coaxial and concentric with two outsides of

33、eyes; pins shall be cut from bars, and machined after forging.5.2.2 Heat treatment shall be made after shackle forging to achieve the properties specified in 5.1, with no more than three times of heat treatment.5.3 Surface and internal quality of shackles5.3.1 The surface of shackles shall be smooth

34、 and clean, without any defect such as burrs, cracks, folding, and burning.5.3.2 Defects in shackles cannot be rewelded.5.3.3 Shoulders or heads of pins (Type W and Type Y) after assembly shall fit into the bodies. When thread pins are screwed up, visible residual threads between dimensions of shack

35、les (W) shall not be more than 1 pitch. After the correct assembly of pins, in no case shall the inner width (W) of the bodies be obviously reduced.5.3.4 Threads shall meet the requirements of ISO 261, and the fit accuracy of threads is 6g/6H.5.4 Test5.4.1 Each shackle shall be proof-tested, with te

36、st loads given in Table 3. Proof load shall be applied to each shackle with a testing machine or test weight for a duration of not less than 5 min.

Increment of the body length (S) or length increment measured from the mark between the crown and pin shall not exceed 0,25 % thereof or 0,5mm, whichever is greater.5.4.3 When shackles of various specifications are manufactured for the

39、first time or upon the request of related organizations, such as classification societies, static strength tests shall be carried out for shackles, the ultimate strength load during the test is four times the safe working load. After 5 min of the static strength test, shackles shall not break or def

41、anufacturer shall provide technical documents such as certifications.5.6 Other requirementsFor other shackles (type or SWL, materials), strength shall be calculated during the design and the result should meet the test requirements in 5.4.3. Commercially available forged shackles that meet industry

42、standards in terms of SWL, design factor, forging reduction, heat treatment, bolt threading, testing, and inspection are acceptable as agreed upon by the supplier and the purchaser.6 Marking6.1 Marking of shackles shall be permanently distinct with the following items:a) safe working load, in t;b) t

43、est date;c) shackle number;d) manufacturers stamp or the stamp of test unit.6.2 Marks shall be stamped at the shackle bodies near the pinholes to facilitate check.6.3 For the shackles of small size, should the place where marking is restricted, the marks of number and date can be eliminated.7 Storag

46、ces, shackles shall be checked before each use, with major check items as follows:a) wear;b) normal operation of moving parts;c) no abnormal conditions such as loose pins and nuts or defects;d) there is no crack, scratch, heat damage, including welding slag, or arc striking mark in shackle bodies.8.

47、2 Shackle defects found during check shall be repaired and cannot be used until confirmation by experienced personnel. Shackles shall be scrapped under the following circumstances.a) There are defects in shackles, such as crack, heat damage, including welding slag, or arc striking mark, which preven
