Wear and Tear (W&T)
Wear and Tear. Damage that naturally and inevitably occurs to equipment as a result of the normal use and aging.
Wind and Water Tight (WWT)
Criteria under which containers would literally be “Wind and Water Tight”. This commonly used criteria makes no reference to the quality of understructure of the container and should therefore not be considered as safe for the transport of cargo unless it was explicitly confirmed that containers meet the CSC.
