The work of preparing International Standards is normally carried out through ISO technical commi
12、ttees. 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 I
13、nternational 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 Internationa
14、l 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
15、 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8082-2 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 15, Machinery for forestry. ISO 8082 consists of the following pa
16、rts, under the general title Self-propelled machinery for forestry Laboratory tests and performance requirements for roll-over protective structures: Part 1: General machines Part 2: Machines having a rotating platform with a cab and boom on the platform BS ISO 8082-2:2011 ISO 8082-2:2011(E) ISO 201
17、1 All rights reserved vIntroduction Earth-moving excavators used in cross-over applications involving sites with trees, but excluding forestry applications, are covered by ISO 12117-2. Because of the similarity between excavators and forestry machines having a rotating platform with a cab, a fixed c
18、ab riser and a boom on a platform, this part of ISO 8082 specifies test methods and procedures similar to those of ISO 12117-2 and ISO 3471.

19、ests and performance requirements for roll-over protective structures Part 2: Machines having a rotating platform with a cab and boom on the platform 1 Scope This part of ISO 8082 establishes a consistent and reproducible means of evaluating the load-carrying characteristics of roll-over protective
20、structures (ROPS) on self-propelled forestry machines under static loading, and gives performance requirements for a representative specimen under such loading. It is applicable to machines configured as forestry machines or defined as such in ISO 6814, having a rotating platform with a cab with or
21、without a fixed cab riser and boom on the same or a separate platform, intended to be operated by an operator wearing a seat-belt. It is not applicable to forestry machines with elevating cabs. 1)2 Normative references The following referenced documents are indispensable for the application of this

For multiple-post ROPS, L is the greatest longitudinal distance from the outer surface of the front to the
