7、 member bodies). The work of preparing International Standards is normally carried out through IS0 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, gover
8、n- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The main task of IS0 technical committees is to prepare International Standards. In e
9、xceptional circumstances a technical committee may propose the publication of a technical report of one of the following types: - type 1, when the necessary support within the technical committee cannot be obtained for the publication of an International Standard, despite repeated efforts; - type 2,
10、 when the subject is still under technical development requiring wider exposure; - type 3, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art“, for example). Technical reports are accepted for public
11、ation directly by IS0 Council. Technical reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical reports of type 3 do not necessarily have to be reviewed until the data they provide are consid
12、ered to be no longer valid or useful.

15、g, set up Working Group 3 to produce a draft proposal on performance requirements for pallets, related to the methods of test being developed by Working Group 2. ISO/TC 51/WG 3 evaluated petformance in relation to the designed load capacity of a pallet for a uniformly distributed load, called the de
16、sign rating, or rating (R 1, However, it was recognized that the actual safe working load for a pallet of a given rating, as determined by test, could vary with the type of load carried and that, for a specific type of load, the maximum working load may be smaller or larger than the rating of a pall
17、et. A draft document listing examples of the relationship between the rating and safe working load was considered by ISO/TC 51 at its ninth meeting in 1983 and it was agreed to be suitable for development as an IS0 Technical Report, to provide general guidance on the subject to all involved in the s
18、election and use of pallets. iii Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/27/2007 04:48:12 MDTNo reproduction or networking permitted without license from IHS -,-,- TECHNICAL REPO
19、RT ISO/TR 10232 : 1989 (E) General-purpose flat pallets for through transit of goods - Design rating and maximum working load I Scope This Technical Report provides guidance on the relationship between the design rating of a pallet (RI and its maximum working load in practice, which depends on the n
20、ature of the load being carried. It applies to general-purpose flat pallets whose rating has been determined by testing in accordance with IS0 8611 using the performance requirements set out in ISO/TR 10233. 2 Normative references The following standards contain provisions which, through reference i
21、n this text, constitute provisions of this Technical Report. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this Technical Report are encouraged to investigate the possibility of applying the most recent editio

23、ance requirements. 3 Definitions For the purposes of this Technical Report, the following defi- nition applies. rating (RI: The designated load capacity of the pallet, in kilograms, assuming an evenly and uniformly distributed load. 4 Relationship between rating and maximum working load For through
24、transit, pallets are often loaded in such a way that the load being carried (the payload) contributes to the overall performance of the loaded pallet. Therefore a given design of pallet is suitable for several different payloads and will have several different maximum. working loads depending on the
25、 nature of the particular payload. However, a given pallet without payload has only one rating (RI, namely its designated load capacity with a uniformly distributed load. This rating, expressed in kilograms, is deter- mined by test and cannot be changed, for example a rating of 1 O00 kg might be ref
26、erred to in a test report as 1 o00 kgR. During palletization, it is the duty of the responsible supervisor to ensure that a safe working load is not exceeded. Table 1 shows the relationship, for different types of load, between the pallet rating (RI and the payload of the pallet which may be conside
