7.4.3 The probes mentioned in 7.4.1 and 7.4.2 and illustrated in Figures 7.1 – 7.4 shall be applied to any
depth that the opening will permit; and shall be rotated or angled before, during, and after insertion
through the opening to any position that is necessary to examine the enclosure. The probes illustrated in
Figures 7.1 and 7.3 shall be applied in any possible configuration; and, if necessary, the configuration
shall be changed after insertion through the opening.
7.4.4 The probes mentioned in 7.4.1 and 7.4.2 shall be used as measuring instruments to judge the
accessibility provided by an opening, and not as instruments to judge the strength of a material; they shall
be applied with the minimum force necessary to determine accessibility.作者: 人在囧途 时间: 2016-2-23 14:59 作者: hanyanchuang 时间: 2016-2-26 12:59
