The test procedures described in ISO 8611-1 are approximate simulations of pallet use. These tests help the pall
24、et designer to establish an initial acceptable balance between the cost and the performance of a pallet design. It is intended that all results of tests performed using this protocol be confirmed and verified using field trials before publication of performance or the commercial implementation of a
25、new pallet design. The nominal load, determined according to this test protocol, does not represent a payload and cannot be verified using field trials. The nominal load is a minimum payload level for use in determining maximum working load according to the procedures in this part of ISO 8611. The m
26、aximum working load can be verified for a specified payload and intended use, using field trials. It is intended that the publication of the maximum working load include a description of the payload and the intended modes of use of the pallet. It is essential to exercise care when comparing the resu
27、lts of tests with historic experience using existing pallet designs. User expectations of pallet performance vary. Some require greater and some accept lower levels of performance. Users are accepting different levels of risk when using pallets. Because of the varied performance expectations of pall
28、et users, the results of tests might not always reflect the users perception of pallet performance in use. The nominal load might not reflect users perception of pallet performance because the nominal load does not represent a payload. It is intended that maximum working loads be used to compare wit
29、h the historic performance of existing pallet designs. Regarding the use of the ISO 8611 series, ISO 8611-1 describes the test methods, ISO 8611-2 describes the performance requirements and selection of tests, and this part of ISO 8611 describes tests for determining maximum working loads for known
30、payloads. ISO 8611-1 and ISO 8611-2 are required for determining nominal load. The nominal load is the lowest safe load value for the specified support conditions, independent of the type of load (excluding concentrated loads). ISO 8611-1, ISO 8611-2 and this part of ISO 8611 are required for determ
31、ining maximum working loads for known payloads. The nominal load for the intended use is established by the selection of tests in ISO 8611-1 and the performance requirement is established from criteria in ISO 8611-2. The following three types of intended use with specified support conditions are def
32、ined: handling of loaded pallets with racking and stacking; handling of loaded pallets without racking; handling of loaded pallets without racking or stacking. To determine the maximum working load by testing in this part of ISO 8611, the deflection under the known payload cannot exceed the limiting
33、 deflection (see 4.2, 4.3 and 4.4) established in ISO 8611-1 and ISO 8611-2. The maximum working load is the greatest payload that a pallet can be permitted to carry in a specific loading and support condition. EN ISO 8611-3:2012 (E) 4 DIN EN ISO 8611-3:2012-10 Guidance is given in Annex A as to the
34、 general effect on performance of different load types and stabilization methods. These can only give guidance as to the likely result from tests with the known payload. Other tests for durability evaluation are specified in ISO 8611-1. EN ISO 8611-3:2012 (E) 5 DIN EN ISO 8611-3:2012-10 1 Scope This
35、 part of ISO 8611 specifies the determination of maximum working load for new flat pallets with known payloads in different handling environments. It is not intended to apply to pallets with a fixed superstructure or a rigid, self-supporting container that can be mechanically attached to the pallet
36、and which contributes to the strength of the pallet. 2 Normative references The following referenced documents are indispensable for the application of this document.
