spiral: a single transverse coil that is the basic element from which metal mesh is fabricated.
splice, flemish eL/c (zvire rope): mechanical splice formed by opening the rope up in a specific manner and reforming it to create a loop or eye. A metal sleeve is slipped over the ends of the splice and mechanically compressed to secure the ends. This method requires special fittings, techniques, and equipment to produce an end termination to meet the requirements of this Volume.
splice, hand tucked (wire rope and synthetic rope): a ioop or eye formed in the end of a rope by tucking the ends of the strands back into the main body of the rope in a prescribed manner.
splice load bearing (web sling): that part of a sling that is lapped and secured to become an integral load bearing part of the sling.
splice, niechanical (wire rope): swaging one or more metal sleeves over the wire rope to form a ioop or eye.
splice, turnback (return loop): mechanical splice in which the rope is looped back on itself and secured with one or more metal sleeves. This method requires special fittings, techniques, and equipment to produce an end termination to meet the requirements of this Volume.
strand laid rope: a wire rope made with strands (usually six to eight) formed around a fiber core, wire strand core, or independent wire rope core (IWRC).
strength (wire rope and structural strand), minimum breaking: load at which a new and unused wire rope or structural strand could be expected to break when loaded to destruction in direct tension.
triangle choker fitting: an end fitting for metal mesh or synthetic web slings; similar to the triangle fitting, except that it also has a transverse slot through which a triangle fitting can be passed to facilitate a choker hitch on the load.
triangle fitting: an end fitting for metal mesh or synthetic web slings, containing a single eye opening for connecting the sling to the lifting device.
yarn: a generic term for a continuous strand of fibers.

9-1.5.4
Tables 9-1.5.4-1 and 9-1.5.4-2 show rated loads for choker hitches for specific grades of chain, provided that the angle of choke is 120 deg or greater [see Fig. 9-1.0-1, illustration (e)].For angles other than those shown in these tables, use the rated load for the next lower angle, or a qualified person shall calculate the rated load.
9-1.5.5
Rated loads for angles of choke less than 120 deg shall he determined by the sling manufacturer, or a qualified person.
9-1.5.6
Other materials and configurations not covered by this Chapter shall be rated in accordance with the recommendation of the sling manufacturer or a qualified person, and shall conform to all other provisions of this Chapter.
9-1.5.7
When components of the sling have a lower rated load than the alloy chain with which it is being used, the sling shall be identified with a rated load consistent with the lowest load rating of any of the components.
SECTION 9-1.6: PROOF TEST REQUIREMENTS
9-1.6.1 General
Prior to initial use, all new and repaired chain and components of an alloy steel chain sling, either individually or as an assembly, shall be proof tested by the sling manufacturer or a qualified person.
9-1.6.2 Proof Load Requirements
(a) For single- or multiple-leg slings, each leg shall be proof loaded to a minimum of 2 times the single leg vertical hitch rated load.
(b) The proof load for components attached to single legs shall be a minimum of 2 times the single-leg vertical hitch rated load.
(c) Master links for double-leg bridle slings, single- basket slings, and master coupling links connected to two legs shall be proof loaded to a minimum of 4 times the single-leg vertical hitch rated load.
(ci) Master links for triple- and quadruple-leg bridle slings and double basket bridle slings shall be proof loaded to a minimum of 6 times the single leg vertical hitch rated load.
SECTION 9-1.7: SLING IDENTIFICATION
9-1.7.1 Identification Requirements
Each sling shall be marked to show
(a) name or trademark of manufacturer.
