ISO 668

ISO 668 - Series 1 freight containers — Classification, dimensions and ratings is an ISO international standard which classifies intermodal freight shipping containers and standardises their size and weight specifications.[1] Introduced in 1968, ISO 668 regulates both external and internal dimensions of containers, as well as the minimum door opening size, where applicable. It also specifies the associated gross weight ratings, and requirements for load transfer areas in the base structures of containers, since amendment 1 of 2005.[2]

1F **** 5 foot 1.460 m / 4' 9.5" 2.438 m / 8' 0" 5080 kg / 11200 lbs
* The standard also recognises containers less than 8 feet in height, under the designations 1AX, 1BX, 1CX and 1DX, with specifications the same as other containers of their length.
** Forty-five foot containers were added to the standard per Amendment 2 of 2005.[3]
*** The maximum gross mass rating of twenty and thirty foot units was updated with Amendment 1 of 2005.[2] Until then, the MGW for 20-ft units was 24,000 kg / 52,900 lbs, and for 30-ft units 25,400 kg / 56,000 lbs.
**** Six and a half and five foot containers (type 1E and 1F) are not in the current edition ISO 668 standard, but were standardised in previous editions,[4] and are still manufactured.[5]
The so-called width of these small-size containers may be perceived as their length, as it is their greatest horizontal dimension, and their doors are typically in the short end(s).
