AS EN 12079.2:2010 – Offshore containers and associated lifting sets Part 2: Lifting sets-Design,manufacture and marking(EN 12079-2:2006, MOD).
5.5 Shackles
5.5.1 Shackles shall meet all requirements of EN 13889 or EN 1677-1 with the additional requirement that the tolerance on the nominal diameter of the shackle pwi shall be —0 + 3 %.
5.5.2 Shackles shall be restricted to:
bolt type pin with hexagon head, hexagon nut and split cotter pm;
5.6 Materials
5.6.1 Impact Testing
Steels shall be impact tested by the Charpy impact (V-notch) method in accordance with EN 10045-1. The impact test temperature shall be equal to the design air temperatixe T0 and the mnrium average impact energy shall be 42 J. However, for welded components (chains, links, rings) it shall be sufficient only to take impact test samples in the weld with the notch centred in the fusion line The position of the weld shall be accurately identified by etching with a suitable reagent before cutting the notches. The minimum average impact energy of the weld shall be 27 J.
Where the cross section of the material to be tested is too smal to allow the standard test specimen to be taken (10 x 10 mm). the requred energy values shall be reduced as follows:
— 10 mm x 7,5 mm : 5/6ths of the above value;
10mm x 5.0mm : 2I3rds of the above value.
NOTE For tests where the size Of the lest piece Is too small (diameter less than 13 mm), tests may be carried out on sempla material which shall be of the same specification and heat treatment,
5.6.2 WeldIng
In addition to the requirements of EN 818-4. qualification of the welding process shall be in accordance with EN ISO 15613.
5.6.3 Materials used In wire rope slings
Materials in wire ropes, ferrules and thimbles shall be in accordance with applicable standards,
5.6.4 Galvanising
Galvanising shall only be carried out under the control of the manufacturer of the component.
5.6.5 Material certificates.
The materials used in all components shall be supplied with an inspection certificate to either EN 10204 type 3.1 B or. in the case of materials in ferrules and thimbles to EN 10204 type 2.2 with content as detailed in Clause 6.
— date of sling manufacture or re-certification:
— a statement that the sling described has been desagned, manufactured and tested In accordance with this European Standard;
— manufacturers authorized signature. In addition:
— for wire rope slings, the grade of terminal fittings and the rope together with a statement that the sling conforms to EN 13414-1;
for chain slings, the 9rade mark 8 and a statement confirming that the sling conforms to EN 818-4 and providing crass reference to the results of any final testing of mechanical properties after heat treatment.
7 Marking
7.1 In addition to the marking required by the relevant indrvidual component standards, the requirements of 7.2-7.4 apply.
7.2 Shackles tilted to a sling, without being assembly secured, shall be indelibly marked with a unique identification.
NOTE In practice, this marking should be applied using low stress’ stanWs, the height of whdi should be a minenum of 5 mm, and positioned away from areas of lxghest tensde stress i.e. applied to the stmit section of the body adjacent to the eye.
7.3 Slings shall be marked with an identification tag permanently attached to the top assembly of the sling The tag shall be made of metal with the marking permanently embossed or stamped. The tag shall be S-sided for chain slings and round for wire rope slings.
7.4 Where two 2-leg slings are selected to function as a 4 leg sling, both shall be marked as a 4 leg sling.
7.5 The marking on tags for chain and wire rope slings shall include:
— number of this standard:
— unique identification number of the sling.
— numberof legs;
diameter of chain or wire rope used, including the top leg wtiere fitted:
— working load limit (WLL) in tonnes:
— maximum angle of the sling legs from the vertical.
— mass of the lifting set (S) in Kg;
NOTE An example of an Identification tag for chain sgs, Is showsi in Annex B.
