10、s (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 organizations,

11、 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 further ma

12、intenance 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.

27、ps is below 10C, the impact energy test temperature 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

28、coaxial and concentric with two outsides of 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

29、.3.1 The surface of shackles shall be smooth 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

30、residual threads between dimensions of shackles (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

31、 Each shackle shall be proof-tested, with test 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 mar

33、k 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 first time or upon the request of related organizations, such as classification societies, static strength tests shall be carried out for

34、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 deform to the extent that they lose the bearing capacity.5.5 Inspection5.5.1 Inspection shall be made after the production of shackles, to en

35、sure that surface and internal quality satisfies the requirements in 5.3 and the requirements in 5.4.2 after the test.5.5.2 For shackles that pass the test, the manufacturer shall provide technical documents such as certifications.5.6 Other requirementsFor other shackles (type or SWL, materials), st

36、rength 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 standards in terms of SWL, design factor, forging reduction, heat treatment, bolt threading, testing, and inspection are acceptable as agr

37、eed 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) test 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 pinh

38、oles 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 Storage and transportation7.1 During storage, the machined surfaces of shackles that pass the test shall be painted with anti-rust oil, and thei

39、r non-machined surfaces shall be painted with anti-rust paint.4 ISO 2013 All rights reservedBS ISO 16857:2013ISO 16857:2013(E)7.2 Secure package shall be made for shackles to prevent collision during transportation.8 Use and maintenance8.1 Upon installation on the lifting appliances, shackles shall

40、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.8.2 Shackle defects fo

41、und 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 prevent them from use.b) T

42、he diameter dimension of the worn moving part reaches 10 % of the total diameter dimension. The length dimension of corroded thread reaches 15 % of its total length dimension.
