BS EN ISO 3164 specifies the deflection limiting volume (DLV) to be used when performing laboratory evaluations of structures which provide protection to operators of earth-moving machinery as defined in ISO 6165.

The dimensions of the orthogonal DLV shall be as shown in Figure 1 and the dimensions of the rounded DLV as shown in Figure 2.
The dimension from the SIP to the rear boundary of the DLV assumes that the seat has 150 mm fore- -aft adjustment. The 210 mm dimension shall be reduced from 210 mm to 135 mm if the seat does not have any fore-aft adjustment. If the fore-aft seat adjustment is less than 150 mm, the 210 mm dimension shall be reduced by one half of the difference between 150 mm and the actual fore- aft seat adjustment.
ROPS (roll-over protective structure) and TOPS (tip-over protective structure) testing shall use either the rounded or the orthogonal DLV. FOPS (falling object protective structure) testing shall use the orthogonal DLV or the rounded DLV with an added orthogonal top head plane.
During lateral loading for TOPS and ROPS testing, it is permissible for the upper portion of the DLV to be rotated laterally about the SIP up to 15° (see Table 1]. During longitudinal loading for TOPS and ROPS testing, it is permissible for the upper portion of the DLV to be rotated forwards about the LA up to 15°. See the examples given in Figure 4. The portion below the SIP of the DLV does not rotate. If there is interference with any machine component, rotation of the DLV shall be limited to the angle at which the interference occurs.BS EN ISO 3164 pdf download.
