20、roduction The aim of this revision is to update the test methods as well as marking and certification of vehicle body structures that are able to take up a part of the forces to secure the cargo. Due to the particular cargo and the body type additional securing of cargo can become necessary and shou
21、ld be determined in each specific case by the shipper, the operator or the driver. BS EN 12642:2016EN 12642:2016 (E) 5 1 Scope This European Standard applies to body structures on commercial vehicles and on trailers. This European Standard sets out basic minimum requirements for standard vehicle bod
22、ies (side walls, front and rear walls) and for reinforced vehicle bodies and specifies appropriate tests. This European Standard applies to all commercial vehicles which are related by design and body type to the body structures described below. Forces applied according to the test requirements desc
23、ribed below can be invoked for load securing purposes. The floor of the vehicle is a part of the sub frame. As long as the floor strength is not defined, the manufacturer should give the necessary information. Testing of the axle load on the floor should be carried out analogous to EN 283. The resul
24、t should be marked in locations according to chapter 6. This European Standard does not apply to vans according to ISO 27956. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated referenc
25、es, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12195-1:2010, Load restraining on road vehicles - Safety - Part 1: Calculation of securing forces IMO/ILO/UNECE, Code of Practice for Packing of Cargo Tran
26、sport Units (CTU Code):2014 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 reinforced vehicle body vehicle body, having a reinforced structure, and complying with the minimum requirements for Code XL according to 5.2, Table 1, or 5.3, Table
27、2 3.2 standard vehicle body vehicle body complying with the minimum requirements of 5.2 (Code L according to Table 1) which, depending on cargo weight and friction, requires additional securing of cargo using lashing equipment 4 General requirements Verification of conformity to the requirements of
28、this standard shall be provided either by: a) dynamic driving tests (see 5.3 and Annex B), b) static tests: 1) airbag test (see 5.2 and Annex A), 2) static inclination test according to EN 12195-1:2010 with the type of cargo as described in the dynamic test (see B.3) and the duration time in 5.2.2,
29、BS EN 12642:2016EN 12642:2016 (E) 6 c) other methods for applying the test forces which are acceptable if equivalence to test methods above can be proved, d) calculation (methods of calculation shall be verified by one of the test methods above). Body structures of the same design or type should be
30、verified by testing the worst case for that design. A calculation or test for the complete system consisting of front, rear and side walls, roof and floor is necessary for the entire structure even if individual components have been taken from sample structures which have been calculated or tested w
31、ith positive results before. However, it is admissible to replace individual components which have successfully been tested within a complete system with others that have yielded the same results in testing. Where a body structure has been tested or calculated successfully as a modular system set, c
32、alculation or testing shall be carried out to verify that the connection between the body structure and the floor complies with the requirements of the standard. The specified test value P, for which the body structure is tested shall be documented in the test certificate according to Annex C and ma
33、rked according to Clause 6. This specified test value P may be different from the technical payload. Information should be provided in the test certificate by the manufacturer about the part of test value P of the front wall at a height of 200 mm and 800 mm. For the side walls the part of the test v
34、alue P should be provided at a height of 800 mm or maximum height (if lower). The specified test requirements apply to the following types of body structures: box type; drop side body with side and tail boards without tarpaulin cover; drop side body with side and tail boards with tarpaulin cover; cu
35、rtainsider. By analogy these test requirements also apply to all other types of body structures. Vehicle body structures shall be tested in the condition in which they are intended to be used (e.g. without additional securing measures). Moreover, if the bodies are equipped with removable components,
36、 these components shall be in operational position during the test. Approval criteria: After finishing the tests (for driving tests see B.5) or calculations the body structure shall show neither permanent deformation nor other changes which would impair its intended use; and the following criteria s
37、hall be satisfied: Maximum deflection of the tested structure during the test shall not exceed 300 mm. At a test force of 100 % of the test value a permanent deformation of 20 mm may occur, but only if the intended use is not impaired. 5 Testing 5.1 General The following test methods are described (
38、see 5.2 and 5.3). BS EN 12642:2016EN 12642:2016 (E) 7 5.2 Static test Airbag test (Annex A) 5.2.1 Requirements Table 1 gives an overview of the details of static test forces. Table 1 Static test forces Component Standard structure Code L Reinforced structure Code XL Front wall Requirement 0,4 P x g

40、y structures with board walls and tarpaulin cover, apply 0,24 P x g for the board walls and 0,06 P x g for the tarpaulin cover. bExcept for double-decker design. cHigher values can be tested and marked. 5.2.2 General The following outlines the test requirements for vehicle body structures. In princi
41、ple, these test requirements apply to all requirement profiles. For each static test the test force shall be applied for at least 5 min. In the testing requirements specified, the mentioned letters shall have the following meaning: P the specified test value P (in kg), for which the body structure i
42、s tested; F the test force according to Table 1; p the required test pressure in MPa. NOTE P can differ from the payload for which the vehicle is designed. 5.2.3 Strength of the front wall The front wall is tested with a test force of F. The test force is applied to the inner face of the front wall
43、to be tested, it shall be applied uniformly on the surface, (width of body structure) x (3/4 of height of body structure), the height, however, shall be at least 1 600 mm (see Figure 1 and Formula (1). Where the front wall height is 1/2 total loading height and loading shall be carried out up to the
44、 specified test value P. A description of the test cargo indicating the friction coefficient shall be provided in order to ensure reproducible test results. B.3.2 Test with other cargo units For specific purposes tests with different cargo types not defined in B.3.1 shall be tested individually. The
45、 test conditions shall be documented. B.4 Measuring technique and assessment The used measuring system shall at least be equipped with a bi-axial acceleration sensor (BAS), which has to be positioned in the centre underneath the cargofloor. In case of using two BAS, they shall be positioned in the f
46、ollowing manner: one shall be positioned in the centre of the front wall halfway up to the body height. The second one shall be mounted underneath the vehicle floor halfway on the tail-section. The tolerance for mounting the sensors is 30 cm. The sampling rate shall be at least 2,56 times higher tha
47、n the filter frequency. While a duration of 80 ms the arithmetic average shall meet the required acceleration value. A low pass filter with a frequency of minimum 25 Hz shall be applied. For example: If a low pass filter of 25 Hz (minimum standard) is used, the sampling rate shall be 64 Hz (25 Hz x
48、2,56 = 64 Hz). BS EN 12642:2016EN 12642:2016 (E) 17 Remark for the brake tests: The force to operate the brake pedal shall be applied unrelieved until the standstill of the vehicle. Remark for the analysis: Alternatively the arithmetic average of the required acceleration is allowed to fall below th
49、e required value by 0,05 g in case this value is applied over a period of one second. B.5 Driving tests B.5.1 Use of a supporting axle To achieve the requested transverse accelerations of the vehicle independently from dry or wet road conditions, the use of a laterally mounted supporting axle is possible. In case of semitrailers the supporting axle shall be positioned as near as possible in front of the first axle. On other vehicles the supporting axle shall be mounted as much as possible in the middle. The position of the supporting axle an
