       This article describes a cleanroom box suitable for
transport outside the cleanroom.  During transport, the assigned
cleanroom class (at least, class 100) is retained inside the box.  In

any difficulty.  Cover and bottom part are secured against
displacement, with one side 15 of the cover, differing from the
