The test p

22、rocedures described in ISO 8611-1 are approximate simulations of pallet use. These tests help the pallet 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 an

23、d verified using field trials before publication of performance or the commercial implementation of a 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 f

24、or use in determining maximum working load according to the procedures in this part of ISO 8611. The maximum 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

25、 and the intended modes of use of the pallet. It is essential to exercise care when comparing the results 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 accepti

26、ng different levels of risk when using pallets. Because of the varied performance expectations of pallet 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 nomin

27、al load does not represent a payload. It is intended that maximum working loads be used to compare with 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 selectio

28、n of tests, and this part of ISO 8611 describes tests for determining maximum working loads for known 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 (e

29、xcluding concentrated loads). ISO 8611-1, ISO 8611-2 and this part of ISO 8611 are required for determining 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 crite

30、ria in ISO 8611-2. The following three types of intended use with specified support conditions are defined: 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

31、by testing in this part of ISO 8611, the deflection under the known payload cannot exceed the limiting 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 suppor
