Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12642:2006. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 12642:2016 (E) 4 Introduction 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 should be determined in each specific case by the shipper, the operator or the driver. SIST EN 12642:2017



EN 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 bodies (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 described 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 result 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 references, 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 Transport 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 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 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, SIST EN 12642:2017



EN 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 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 with 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, calculation 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 marked 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 value 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; — curtainsider. 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, 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 shall 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 (see 5.2 and 5.3). SIST EN 12642:2017



EN 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 and max. limit 50 kNc 0,5 P x g without max. limit Section 5.2.3 5.2.3 Rear wall Requirement 0,25 P x g and max. limit 31 kNc 0,3 P x g without max. limit Section 5.2.4 5.2.4 Side wall Requirement 0,3 P x ga 0,4 P x gb Section 5.2.5 5.2.5 a For curtainsiders without board walls, apply 0,15 P x g; for body 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. b Except for double-decker design. c Higher values can be tested and marked. 5.2.2 General The following outlines the test requirements for vehicle body structures. In principle, 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 is 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 to be tested, it shall be applied uniformly on the surface,
the height, however, shall be at least 1 600 mm (see Figure 1 and Formula (1)). Where the front wall height is < 1 600 mm the full height of the body structure shall be taken into account for a uniform distribution of the test force applied. SIST EN 12642:2017
