15、y test method and performance requirements for operator protective structures (OPS) on forestry machines. It is applicable to mobile forestry machines as defined in ISO 6814 engaged in felling, processing, forwarding and skidding. The OPS are designed to provide reasonable protection from penetratin
16、g objects such as saplings, branches, broken winch lines and poking hazards in forestry work, but not from small, thrown objects such as chain teeth. Those OPS meeting the performance criteria will not provide complete operator protection under all conceivable circumstances, but are expected to mini
17、mize the possibility of operator injury in normal operational situations. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenc

19、tions For the purposes of this document, the following terms and definitions apply. 3.1 operator protective structure OPS system of structural members arranged in such a way as to minimize the possibility of operator injury from penetrating objects (such as whipping saplings, branches and broken win
20、ch lines) 3.2 roll-over protective structure ROPS system of structural members whose primary purpose is to reduce the possibility of a seat-belted operator being crushed should the machine roll over NOTE These structural members include any subframe, bracket, mounting, socket, bolt, pin, suspension
21、or flexible shock absorber used to secure the system to the machine frame, but exclude mounting provisions that are integral with the machine frame. DIN ISO 8084:2017-05 6 3.3 falling-object protective structure FOPS system of structural members arranged in such a way as to provide operators with re
22、asonable protection from falling objects (e.g. trees, rocks) 3.4 deflection-limiting volume DLV orthogonal approximation of a large, seated, male operator as defined in ISO 3411 wearing normal clothing and a protective helmet 4 Laboratory tests CAUTION Some of the tests specified in this Internation
23、al Standard involve the use of processes which could lead to a hazardous situation. 4.1 Apparatus 4.1.1 Material, equipment and tie-down means adequate for ensuring that the OPS and its machine structure resist the applied force. 4.1.2 Apparatus necessary for pushing a test object into each surface
24、tested, consisting of a steel hemispherical rod-end of 90 mm diameter. For testing glass or polycarbonate, a non-metallic pad, of rubber or synthetic compound, shall be used. The pad shall be of homogenous construction and uniform density, 20 mm thick, 90 mm in diameter and with a Shore type-A hardn
25、ess value of 90. 4.1.3 Instrumentation for measuring the force applied to the OPS and the deflection of the structure, to an accuracy in accordance with Table 1. Table 1 Instrumentation accuracy requirements Parameter Tolerance Measured dimensions null 5 % of maximum dimensions Measured force null 5
26、 % of maximum force required 4.2 Preparation 4.2.1 The deflection-limiting volume (DLV) and its location shall be in accordance with ISO 3164. The DLV shall be secured firmly to the same part of the machine to which the operators seat is fixed, and shall remain there during the entire test period. O
27、n machines equipped with more than one seat position, the tests shall be conducted with the seat in the position that brings the DLV closest to the OPS for each surface tested. 4.2.2 The OPS shall be attached to the machine frame as it would be on an operating machine. A complete machine is not requ
28、ired; however, the machine frame and OPS mounting shall represent an operating installation. DIN ISO 8084:2017-05 7 4.2.3 All detachable windows and panels that are not part of the OPS and which might be removed from an operating machine shall be removed so that they do not contribute to the strengt
29、h of the OPS. 4.2.4 Glazing material that does not contribute to the structural performance of the OPS may be removed for the test. 4.2.5 Where the same structure is used for multiple tests, panels weakened or deformed by previous tests may be replaced. 4.2.6 If the OPS is mounted on a complete mach
30、ine, the machine frame shall be secured so that the test energy is absorbed by the OPS structure alone. 4.3 Procedure 4.3.1 Slowly apply the force (5 mm/s max., to approximate static loading) from the test object normal to the exterior surface under test until this applied force attains a value of 1
31、7 800 N. Sustain the force at this value for 1 min before releasing it. 4.3.2 In the case of open-mesh material, apply the loading such that the projection of the line of force passes through the centre of the mesh opening. !4.3.3 Perform five loadings on the opening at the following locations: a) t
32、he centre; b) mid-way along the longest side; c) mid-way along the shortest side; d) at the sharpest corner; e) at the dullest corner. When testing the sides, the loading shall be 50 mm from the edge. The order of the testing shall be a, b, c, d, and then e. If a loading test point overlaps the 90 m
33、m hemisphere of a previous test point, the subsequent test point may be omitted.“ 5 Performance requirements 5.1 Test acceptance When the test is performed anywhere on the OPS, the DLV, in accordance with ISO 3164, shall not be entered by any part of the OPS or the test object, and the major diamete
34、r of the test object shall not pass through the surface under test. 5.2 Constructional requirements 5.2.1 The operator station shall be completely enclosed with solid material, by a screen or with glazing, including full doors. DIN ISO 8084:2017-05 8 5.2.2 No opening in an OPS surface shall allow a
35、straight, rigid bar, 48 mm in diameter, to freely enter the OPS. 5.2.3 Protective screens shall have a maximum opening of 45 mm null 45 mm, with 6 mm woven wire mesh or equivalent construction. 5.2.4 Glazing material meeting requirements may be used anywhere on the machine, including the front winds
36、creen. If wipers are to be used, the glazing surface shall be hard-coated. 5.2.5 Guards or screens provided for OPS window protection shall be designed to allow manual cleaning of the windows. 5.2.6 The OPS should be designed to minimize any adverse effects on operator visibility, comfort and protec
37、tion against hazards generally. 5.2.7 The OPS may be attached to, or form part of, a ROPS/FOPS, provided that such attachment does not adversely affect the function or performance of the ROPS or FOPS. 5.2.8 Provision shall be made on the OPS for two means of egress, each on a different surface of th
38、e OPS, in order to provide an emergency exit.
