BS ISO 668:2020 pdf download – Series 1 freight containers — Classification, dimensions and ratings.
1 Scope This document establishes a classification of series 1 freight containers based on external dimensions, and specifies the associated ratings and, where appropriate, the minimum internal and door opening dimensions for certain types of containers. These containers are intended for intercontinental traffic. This document summarizes the external and some of the internal dimensions of series 1 containers. The dimensions of each type of container are defined in the appropriate part of ISO 1496, which is the authoritative document for internal container dimensions. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

5 Dimensions, tolerances and ratings 5.1 Reference temperature for measurements The dimensions and tolerances apply when measured at the temperature of 20 °C (68 °F); measurements taken at other temperatures shall be adjusted accordingly. 5.2 External dimensions, tolerances and ratings 5.2.1 External dimensions and tolerances The external dimensions and permissible tolerances given in Table 2 are applicable to all types of containers, except that a reduced height is permissible for tank, open top, bulk, platform and platform- based type containers. 5.2.2 Ratings The ratings given in Table 2 are applicable to all types of containers, except that for particular traffic, higher values are permissible for containers of any type specified in Table 2. Such containers are considered as ISO containers provided that their maximum gross mass, R, does not exceed 36 000 kg and that they are tested and marked to their actual rating, R (see 3.3).
