1 Scope
This International Standard specifies the deflection- limiting volume (DLV) to be used when performing laboratory evaluations of structures which provide protection to operators of earth-moving machinery.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
ISO 3411 :_1), Earth-moving machinery — Human physical dimensions of operators and minimum operator space envelope.
ISO 5353:1995, Earth-moving machinery, and tractors and machinery for agriculture and forestry — Seat index point.
3. Definitions
For the purposes of this International Standard, the following definitions apply.
3.1 deflection-lImiting volume; DLV: Orthogonal approximation of a large, seated, male operator as defined in ISO 3411 wearing normal clothing and a protective helmet.
See figure 1.
3.2 locating axis; LA: Horizontal axis for positioning the DLV with respect to the seat index point (SIP).
See figure 1.
4 Accuracy
All linear dimensions of the DLV shown in figure 1 shall have a tolerance of ± 5 mm. The accuracy of locating the DLV with respect to the seat index point (SIP) shall be ± 13 mm, horizontally and vertically.
5 Location of DLV
NOTE 1 Machine controls and their components normally positioned in the DLV are not considered to violate the DLV.
5.1 The DLV shall be located using the SIP, as defined in ISO 5353. as the reference point (see figure 1).
5.2 For machines which have multiple machine function seats and therefore multiple SIPs (see ISO 5353:1995, 5.3.3). the SIP used by the operator to move the machine in the travel mode shall be used.
5.3 The DLV shall be positioned so that the locating axis, LA, shown in figure 1 passes through the SIP. The DLV shall be centred transversely in the seat location with its principal axes horizontal and vertical (axes X’ and Z’ as defined in ISO 5353:1995, figure 2).
5.4 The location of LA of the DLV shall remain co- incidental with the SIP even though that line may move during any or all of the laboratory loadings. BS EN ISO 3164 pdf download.
