Abstract This standard defines the electrical measurement techniques and acceptable performance limits for vari- ous test parameters on the collection of wires, connectors, and circuits that form the electrical path be- tween SCSI devices. This document specifies the details of the measurement me
4、thodology to minimize the error in results from different electrical testing laboratories. Details are given at each stage of testing including calibration, fixturing and sample preparation.

6、een met by the standards developer. Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity
7、. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from
8、manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall hav

Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This Am
10、erican National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all sta
