SECTION V: EFFECTIVE DATE (a) Effective Date. The effective date ofthis Volume of the B30 Standard shall be 1 yr after its date of issuance. Construction, installation, inspection, testing, mainte- nance, and operation of equipment manufactured and facilities constructed after the effective date of this Volume shall conform to the mandatory requirements of this Volume. (b) Existing Installations. Equipment manufactured and facilities constructed prior to the effective date of this Volume of the B30 Standard shall be subject to the inspection, testing, maintenance, and operation re- quirements of this Standard after the effective date. Itis notthe intentofthis Volume ofthe B30 Standard to requireretrofittingofexistingequipment. However, when an item is being modified, its performance requirements shall be reviewed relative to the requirements within the current volume. The need to meet the current require- ments shall be evaluated by a qualified person selected by the owner (user). Recommended changes shall be made by the owner (user) within 1 yr. SECTION VI: REQUIREMENTS AND RECOMMENDATIONS Requirements ofthis Standard are characterized byuse ofthe word shall. Recommendations ofthis Standard are characterized by the word should. SECTION VII: USE OF MEASUREMENT UNITS This Standard contains SI (metric) units as well as U.S. Customaryunits.Thevalues statedinU.S. Customaryunits areto beregardedas thestandard. TheSI units areadirect (soft) conversion from the U.S. Customary units.
SECTION IX: REQUESTS FOR INTERPRETATION The B30 Standards Committee will render an interpre- tation ofthe provisions ofthe B30 Standard. An Interpre- tation Submittal Form is available on ASME’s website at http://cstools.asme.org/Interpretation/Interpretation- Form.cfm. Phrase the questionas arequestforaninterpretationof a specific provision suitable for general understanding and use, not as a request for approval of a proprietary design or situation. Plans or drawings that explain the question may be submitted to clarify the question. However, they should not contain any proprietary names or information. Read carefully the note addressing the types of requests that the B30 Standards Committee can and cannot consider. Upon submittal, the request will be forwarded to the relevant B30 Subcommittee for a draft response, which will then be subject to approval by the B30 Standards Committeepriorto itsformalissuance.

SECTION X: ADDITIONAL GUIDANCE The equipment covered by the B30 Standard is subject tohazardsthatcannotbeabatedbymechanicalmeans,but only by the exercise of intelligence, care, and common sense. It is therefore essential to have personnel involved intheuseandoperationofequipmentwho arecompetent, careful, physically and mentally qualified, and trained in theproperoperationofthe equipmentand thehandlingof loads. Serious hazards include, but are not limited to, improper or inadequate maintenance, overloading, drop- pingorslippingofthe load, obstructingthe free passage of the load, and using equipment for a purpose for which it was not intended or designed.
fabric(metalmesh): the flexible portion ofthe sling exclu- sive of end fittings consisting of a series of transverse spirals and cross rods. fabric length (metal mesh): the distance of metal mesh between the end fittings. fabric thickness (metal mesh): the nominal overall thick- ness of the spirals. fabrication efficiency: the strength ofthe fabricated sling, as a percentage of the material strength prior to fabrica- tion. fitting: any load-bearing hardware used to fabricate the slingsuchasaswagesleeveforwireropeoracouplinglink for alloy chain, or an end attachment such as a hook or master link. flemish eye splice: a mechanical splice formed by unlaying the wire rope body into two parts and reforming it to create a loop or eye. The splice is completed by pressing (swaging) a metal sleeve over the rope juncture. grommet(wire rope): a wire rope slingmade endless from one continuous strand (strand-laid) formed to make a six- strand rope with a strand core, or one continuous rope (cable-laid) formed to make a body of six ropes around a rope core. The strand or rope ends (as applica- ble) are hand-tucked into the body. hand-tuckedsplice(wireropeandsyntheticrope): aloop or eye formed in the end ofa rope by tucking the ends ofthe strandsbackintothemainbodyoftheropeinaprescribed manner. high tenacity fiber: fiber that has a tenacity of 15 g per denier or higher. hitch (hitched): a method of rigging (attaching) a sling temporarily to a load or object for the purpose of load handling.
