5、f 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. In

6、ternational 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

7、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

8、 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 13194 was prepared by Technical Committee

9、ISO/TC 51, Pallets for unit load method of materials handling. ISO 13194:2011(E) ISO 2011 All rights reserved vIntroduction This International Standard provides definitions and specifies principal requirements and test methods for box pallets, excluding tank and silo pallets as defined in ISO 445. I

10、t is performance-based, i.e. no minimum values are fixed. It reflects ISO 8611-1 in this respect. Box pallets are tested in accordance with the claimed performances. This International Standard evaluates performances in relation to the load capacity of a box pallet carrying a uniformly distributed l

11、oad used as test load and called the nominal load. However, it is recognized that the maximum working load for a box pallet could vary with the type of load carried and that, for a specific type of load, the maximum working load can be smaller or larger than the nominal load of a box pallet. Therefo

12、re, the allowable maximum load for a given design of box pallet varies according to the characteristics of the type of load carried. INTERNATIONAL STANDARD ISO 13194:2011(E) ISO 2011 All rights reserved 1Box pallets Principal requirements and test methods 1 Scope This International Standard specifie

13、s the definitions, principal requirements and test methods for box pallets of all materials. It applies to box pallets, including post pallets and cage pallets, but is not intended to apply to tank and silo pallets as defined in ISO 445. It also applies to box pallets which can be stacked and handle

14、d by forklift trucks or pallet trucks, but excludes other lifting devices. This International Standard addresses the performance of the box pallet only, and not its contents. 2 Normative references The following referenced documents are indispensable for the application of this document.
