The final draft was established on the basis of comments received during a parallel enquiry on the draft. This final draft is hereby submitted to the ISO member bodies and to the CEN member bodies for a parallel two-month approval vote in ISO and formal vote in CEN. Positive votes shall not be accompanied by comments. Negative votes shall be accompanied by the relevant technical reasons. ISO 2012 All rights reserved iii

5 ISO/FDIS 3164:2012(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3164 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2, Safety, ergonomics and general requirements. This sixth edition cancels and replaces the fifth edition (ISO 3164:1995), which has been technically revised. iv ISO 2012 All rights reserved

6 FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 3164:2012(E) Earth-moving machinery Laboratory evaluations of protective structures Specifications for deflectionlimiting volume 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 as defined in ISO Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 3411:2007, Earth-moving machinery 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 ISO 6165, Earth-moving machinery Basic types Identification and terms and definitions 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 deflection-limiting volume DLV approximation of a large seated operator as defined in ISO orthogonal DLV DLV (3.1) that is an orthogonal approximation of an operator NOTE See Figure rounded DLV orthogonal DLV (3.1.1) with corners rounded to approximate the curvature of the operator (e.g. head, shoulders) NOTE See Figure orthogonal top head plane 270 mm by 330 mm rectangular horizontal surface used with the rounded DLV (3.1.2) to replicate the top horizontal surface of the orthogonal DLV (3.1.1) NOTE 1 See Figure 3. ISO 2012 All rights reserved 1

7 ISO/FDIS 3164:2012(E) NOTE 2 This top head plane is to be used with the rounded DLV when testing a FOPS (falling-object protective structure). 3.2 seat index point SIP point on the central vertical plane of the seat as determined by ISO locating axis LA horizontal axis for positioning the DLV (3.1) with respect to the SIP (3.2) 4 DLV dimensions, use and accuracy 4.1 The dimensions of the orthogonal DLV shall be as shown in Figure 1 and the dimensions of the rounded DLV as shown in Figure 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. 4.3 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. 4.4 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. 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. Table 1 Summary of allowed DLV rotation during ROPS/TOPS testing ROPS/TOPS loading direction Degrees DLV rotation direction Lateral loading 15 Lateral Longitudinal loading 15 Longitudinal The rounded DLV better represents the shape of the operator s head when the DLV is rotated in the longitudinal and lateral directions. 4.5 All linear dimensions of the DLV shown in Figures 1 and 2 shall have a tolerance of ±5 mm. The accuracy of locating the DLV with respect to the SIP shall be ±13 mm, horizontally and vertically. The accuracy of the rotation shall be ±1. 5 Location of DLV 5.1 The DLV shall be located using the SIP, as defined in ISO 5353, as the reference point (see Figures 1 and 2). 2 ISO 2012 All rights reserved

10 ISO/FDIS 3164:2012(E) 5.2 For machines which have multiple seat locations 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 location as determined in 5.2. 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 the LA of the DLV shall remain coincidental with the SIP even though that line can move during any or all of the laboratory loadings. NOTE Machine controls and their components normally positioned in the DLV are not considered to violate the DLV.

Use of may allows the use of either the 210 mm dimension or the reduced dimension. SE 4.2 te The DLV together with the requirements from ISO 3471 simulates a safety cage around the operator. Now it is proposed to reduce this cage if the seat is not adjustable. US 4.4 Ge Is this section controlling for all ROPS/TOPS standards, or does each standard need to explicitly allow rotation of the DLV? Currently some standards do (e.g. ISO 12117) while others do not (e.g. ISO 3471). SE 4.4 te The DLV together with the requirements from ISO 3471 simulates a safety cage around the operator. Now it is proposed to reduce this cage allowing the operator to rotate 15o according to figure 4c. This has not been allowed in the previous version of this std. In addition it is allowed to use 15o LSGP according to figure 6 in ISO For many narrow machines a single bare in the middle of the machine would fulfil the requirements for a ROPS. SE 4.5 te The tolerances on the DLV zone shall not allow any minus tolerances, and the rotation angle shall be max 15o. SE 5.2 te Clarify if a position used by the operator during work mode and where a risk of roll over exist shall be used for the ROPS test or if you are free to choose road travel mode that probably are less restrictive choice. IT 5.4 Figure 1 and ed In the legend there is no reference to LA Figure 2 Change may to shall (two places): The 210 mm dimension shall be reduced... Keep the current DLV unless investigation and tests shows that we don t reduce safety. If each individual ROPS/TOPS standard must explicitly allow DLV rotation, add a clarifying statement to that effect. Keep the current DLV unless investigation and tests shows that we don t reduce safety. Here we really need evidence that we still have a safe machine during a roll-over also after we allow 15o rotation. Delete tolerances. For machines which have multiple seat locations the worst case position that is able to be used during operation shall be used. Add LA in the key Not. The DLV provides adequate operator space for small machines without seat adjustement ISO 3164 applies to all ROPS/FOPS/TOPS testing so no change is needed. Not accepted. During a tip or a roll-over, the operator will move in the cab if the cab deflects. Not accepted. The tolerances were not changed and the current tolerances have been acceptable.

The Top view of Figure 2 does not show the trimming lines which are evident in the orthogonal projection of Figure 3. Figure 3 shows a rounding of the DLV back plane which was never discussed and is in contrast with the view of Figure 2, showing sharp corners. The radius of curvature of this rounding is not indicated as well. Revise completely Figure 2 and Figure 3 to make them consistent with the text and feasible. Check with ISO the possibility to make available a 3D solid model in some sort of public format to assist users of the standard to apply the requirement consistently (see below).
