SECTION V: EFFECTIVE DATE (a) Effective Date. The effective date of this 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. [bj 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. It is not the intent of this Volume of the B30 Standard to require retrofitting of existing equipment. 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: REQUIREMENTSAND RECOMMENDATIONS Requirements of this Standard are characterized by use of the word shall. Recommendations of this Standard are characterized by the word should. SECTION VII: USE OF MEASUREMENT UNITS This Standard contains SI (metric) units as well as U.S. Customary units. The values stated in U.S. Customary units are to be regarded as the standard.
SECTION IX: REQUESTS FOR INTERPRETATION The B30 Standards Committee will render an interpre ­ tation of the provisions of the B30 Standard. An Interpre ­ tation Submittal Form is available on ASME ’ s website at http://cstools.asme.org/Interpretation/Interpretation- Form.cfm . Phrase the question as a request for an interpretation of 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 Committee prior to its formal issuance. The B30 Standards Committee may rewrite the question for the sake of clarity. Interpretations to the B30 Standard will be available online at https://cstools.asme.org/Interpretation/ Searchinterpretation.cfm. SECTION X: ADDITIONAL GUIDANCE The equipment covered by the B30 Standard is subject to hazards that cannot be abated by mechanical means, but only by the exercise of intelligence, care, and common sense. It is therefore essential to have personnel involved in the use and operation of equipment who are competent, careful, physically and mentally qualified, and trained in the proper operation of the equipment and the handling of loads.
SECTION 9-0.1: SCOPE OF ASME B30.9 Volume B30.9 includes provisions that apply to the fabrication, attachment, use, inspection, testing, and maintenance of slings used for load-handling purposes, used in conjunction with equipment described in other volumes of the B30 Standard, except as restricted in ASME B30.12 and ASME B30.23. Slings fabricated from alloy steel chain, wire rope, metal mesh, synthetic fiber rope, synthetic webbing, and polyester and high performance fiber yarns in a cover(s] are addressed. (21) SECTION 9-0.2: DEFINITIONS abnormal operating conditions: environmental conditions that are unfavorable, harmful, or detrimental to or for the operation of a sling such as excessively high or low ambient temperatures, exposure to weather, corrosive fumes, dust-laden or moisture-laden atmospheres, and hazardous locations. abrasion: the mechanical wearing of a surface resulting from frictional contact with other materials or objects. angle of choke: the angle formed in a sling body as it passes through the choking eye or fittings. angle of loading: the acute angle between the sling leg and the plane perpendicular to the direction of applied force, sometimes referred to as horizontal angle when lifting (see Figure 9-1. 5-1], basket hitch: a method of rigging a sling in which the sling is passed around the load, and both eye openings or end fittings are attached to a hook, shackle(s), or other load ­ handling device. body (sling): that part of a sling between the eyes, end fittings, or loop eyes.
