5.4 Altitude simulation test method
Many shipping methods subject packaging to stress from changes in altitude. High altitude truck routes
can cause package expansion and failures. Air cargo holds are typically pressurized to only 9,000 feet
(2,743 meters). The Pack-Vac™ can reveal potential weaknesses in the package before shipping.
Altitude simulation can be done wet or dry. Vacuum levels can be converted to altitude with chart. Alti-
tude reading will be a differential from current altitude. For absolute altitude, add the local altitude of the
testing facility.
