21、gdom. BS EN 12674-4:2015EN 12674-4:2015 (E) 4 Introduction Roll containers and dollies are equipment intended for moving goods. They comprise apparatus fitted with fixed and/or swivel castors. For roll containers the superstructure comprises two or more frames which provide retention for items requi
22、ring transport and/or distribution. Dollies and roll containers can be supplied in a variety of materials and additionally roll containers are supplied in four main styles. One of these styles, the Nesting style, is further sub-divided into five derived forms and the Demountable style is sub-divided
23、 into two derived forms. EN 12674-1 gives details of how these styles differ. EN 12674-2 gives methods of measuring working dimensions and aspects of design that manufacturers need to be aware of. Test methods are given in EN 12674-3 which are supported by performance levels in this Part 4, which ta
24、ke account of the normal static and dynamic loads applied in use. This European Standard specifies minimum levels of performance for critical tests, in particular with reference to safety. Certain tests which are related only to longevity, quality control or need development are optional and if carr
25、ied out may be subject to agreement between manufacturer and user. Tests are applied to fully assembled roll container and dolly specimens as indicated in Table 1. Dismantled or nested roll containers are not subjected to testing; however, empty dollies stacked ready for use, storage or transit need
26、 to be subjected to normative testing in order to determine a safe number of stacked units. In order to calculate applied test loads a nominal safe working load (SWL) of 250 kg is assumed in this European Standard for every specimen. The value of 250 kg is not a normative level and may be reduced or
27、 increased by the testing body in collaboration with the specimen supplier/manufacturer. However, if different, the level used should be clearly stated in the test report. BS EN 12674-4:2015EN 12674-4:2015 (E) 5 1 Scope This European Standard specifies appropriate tests and levels of performance for
28、 roll containers and dollies manufactured in all materials, assembled for use and stacked for storage when tested in accordance with EN 12674-3. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
29、 For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

34、specimen before collapse or failure 3.7 safe working load (SWL) maximum permissible load in kg to be carried by a particular design of roll container or dolly during its service life 4 Sampling of roll containers to be tested 4.1 Sequence of tests All tests are independent of each other and may be c
35、arried out in any order. Results shall be listed in identical order to tests listed in this European Standard. A new untested or undamaged specimen or component shall be used in each test. All tests other than those referred to in 5.1.2 and 5.10.2 are prototype tests and may therefore result in dest
36、ruction or damage to the specimen. Unless otherwise stated by the roll container or dolly supplier/manufacturer and in order to calculate applied test loads a nominal safe working load (SWL) of 250 kg is assumed for every specimen. The value of 250 kg SWL is not a normative level and may be reduced
37、or increased by the testing body in collaboration with the specimen supplier/manufacturer. However, if modified, the SWL level used shall be clearly stated in the test report. 4.2 Applicability of normative tests The following tests shall be applied to fully assembled roll container and dolly specim
38、ens where indicated in Table 1. Some tests are conducted on empty specimens and some with load as specified. Where specific performance requirements relating to individual tests apply, they are given in Clause 5. Stacked dollies and dismantled stacked roll container bases intended for stacking shall
39、 be subjected to normative stability testing as detailed in 5.1.3. Dismantled or nested roll containers are not subjected to normative testing.

NOTE 2 No recommendation is made fo
44、r stability performance for the roll container known as a dairy cage. NOTE 3 The standard dummy load in normative test 4.2.1 of EN 12674-3:2004 does not vary with roll container or dolly type, size or SWL since direct comparisons between designs would then be impossible. Additional tests may be spec
45、ified by a manufacturer or user, but if specified are not part of this European Standard. 5.1.2 Dolly - dummy load With dummy load W equal to 50 kg, centrally placed at h = 250 mm, the minimum angle of inclination of the supporting table before instability or topple shall not be less than = 28 in an
46、y of four directions R, L, F or B. 5.1.3 Dolly - stacked empty With supporting test bed table set horizontal with = 0, estimate the number of identical stacked units that will achieve stability. Place these in stacked position with the longest dolly dimension parallel to the test bed table hinge, se
47、tting castors on the supporting test bed table hinge-side in toe-in position. Incline the table slowly to = 7 and fix securely at this angle while holding stacked units secure, then add or subtract units until the stack just achieves stability. Record the number of stacked units. NOTE If a manufactu
48、rers moulded depressions in the dolly top deck forces an alternative castor position to toe-in, then these will take precedence and be used in the test. 5.1.4 Roll container (unloaded) Without load the minimum angle of inclination before instability or topple shall not be less than = 15 in any of fo
49、ur directions R, L, F or B. 5.1.5 Roll container (dummy load) With dummy load W equal to 50 kg, centrally placed at h = 250 mm, the minimum angle of inclination before instability or topple shall not be less than = 19 in any of four directions R, L, F or B. 5.2 Diagonal resistance test (4.2.2 of EN 12674-3:2004) For empty dollies and roll containers the test load as specified in EN 12674-3 shall be applied across the specimen diagonal d1such that F equals 0,6 SWL.
