Specifies the main dimensions of V-belts intended for use on agricultural machinery (in particular harvester-thresher machines), together with the grove section of the corresponding fixed- or variable-diameter pulleys. Tabulates nominal values of datum length from 630 mm up to and including 5 000 mm. Some figures illustrate shapes and reference quantities of concern.
