Your comments on this draft are invit
9、ed and will assist in the preparation of the consequent standard. Comments submitted will be reviewed by the relevant BSI committee before sending the consensus UK vote and comments to the international secretariat, which will then decide appropriate action on the draft and the comments received. If
10、 no comments are received to the contrary, then the UK will approve this draft. If the international standard is approved, it is possible the text will be published as an identical British Standard. UK Vote Please indicate whether you consider the UK should submit a negative (with reasons) or positi
11、ve vote on this draft. Submission The guidance given below is intended to ensure that all comments receive efficient and appropriate attention by the responsible BSI committee. Annotated drafts are not acceptable and will be rejected. All comments must be submitted, preferably electronically, to the
12、 Responsible Committee Secretary at the address given on the front cover. Comments should be compatible with Version 6.0 or Version 97 of Microsoft Word for Windows, if possible; otherwise comments in ASCII text format are acceptable. Any comments not submitted electronically should still adhere to
13、these format requirements. All comments submitted should be presented as given in the example below.

31、d 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 technica
32、l 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 ele
33、ctrotechnical 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 th
34、e 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 ide
35、ntifying any or all such patent rights. ISO 8611-2 was prepared by Technical Committee ISO/TC 51, Pallets for unit load method of materials handling. This edition cancels and replaces ISO/TS 8611-2: 2005, which has been technically revised. ISO 8611 consists of the following parts, under the general

39、 1 1 Scope This part of ISO 8611 specifies the performance requirements and the selection of tests for flat pallets of all materials being subjected to the tests defined in ISO 8611-1. It is not intended to apply to pallets with a fixed superstructure or a rigid, self-supporting container that may b
40、e mechanically attached to the pallet and which contributes to the strength of the pallet. 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 editio

When several materials are used, the most sensitive condition shall be used. 4.2 Wooden pallets The reference moi
48、sture content is (20 2) %. If the pallets are used at a higher moisture content, they shall be tested at this higher moisture content and the moisture content shall be recorded in the test results. NOTE Electrical measurements permit subsequent allowance to be made for the effect of moisture content
