The internal dimensions and door openings of most containers exceed the above given dimensions. However, the dimensions mentioned on the following pages are nominal figures. Because of production tolerances a difference in measurements is possible:
| Tolerances | Length | Width | Height |
| Maximum Difference | 10 mm 3/8″ | 10 mm 3/8″ | 10 mm 3/8″ |
Maximum Gross Weights
20′ containers:
24,000 kg (52,910 lbs) according to the latest issue of ISO 668;
30, 480 kg (67,200 lbs) valid for most 20′ containers; exceeds ISO minimum standards.
40′ containers:
30,480 kg (67,200 lbs).
Floor Loads
A container floor is capable of carrying a fork-lift truck with a maximum axle load of 5,460 kg (12,040 lbs), if the contact area per wheel is at least 142 cm2 (22 sq.in) (ISO 1496/I).
When stowing heavy cargo in containers other than flats or platforms due care has to be taken that concentrated loads will not exceed the strength of the bottom construction of the container.
The maximum spreaded load should not exceed
-for 20′ containers 4 ts per running meter in length (3′ 3.5″)
-for 40′ containers 3 ts per running meter in length.
