26、 ISO 8611-2:2011ISO 8611-2:2011(E) ISO 2011 All rights reserved vIntroduction The forces to which pallets are exposed during use vary significantly. The test procedures described in ISO 8611-1 are approximate simulations of pallet use. These tests help the pallet designer to establish an initial acc
27、eptable 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 new pallet design. The nominal load, de
28、termined 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 ISO 8611-3. The maximum working load can be verified for a specifie
29、d 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 results of tests with historic experience using existi
30、ng 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 pallet users, the results of tests might not always re
31、flect 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 with the historic performance of existing pallet desi
32、gns. Regarding the use of the ISO 8611 series, ISO 8611-1 describes the test methods, this part of ISO 8611 describes the performance requirements and selection of tests, and ISO 8611-3 describes tests for determining maximum working loads for known payloads. ISO 8611-1 and this part of ISO 8611 are
33、 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, this part of ISO 8611 and ISO 8611-3 are required for determining maximum working loads for known p
34、ayloads. 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 this part of ISO 8611. The following three types of intended use with specified support conditions are defined: handling of loaded pal
35、lets with racking and stacking; handling of loaded pallets without racking; handling of loaded pallets without racking or stacking. To determine the maximum working load through testing given in ISO 8611-3, the deflection under the known payload cannot exceed the limiting deflection (see 4.2, 4.3 an
36、d 4.4 of ISO 8611-3:2011) established in ISO 8611-1 and this part of ISO 8611. The maximum working load is the greatest payload that a pallet can be permitted to carry in a specific loading and support condition.

39、ndling Flat pallets Part 2: Performance requirements and selection of tests 1 Scope This part of ISO 8611 specifies the performance requirements to establish nominal loads for new flat pallets. It also specifies the tests required for new flat pallets in various handling environments and the perform
40、ance requirements for tests with payloads. 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 and which contributes to the strength of the pallet. 2 Normative references The following referenced doc
