EN 13545:2002 (E)3ForewordThis document EN 13545:2002 has been prepared by Technical Committee CEN/TC 261 "Packaging",the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by October 2002, and conflicting national standards shallbe withdrawn at the latest by October 2002.Annex A is informative. Annex B is normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands,Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13545:2002

EN 13545:2002 (E)4IntroductionThis European Standard is intended for new and mainly reusable pallet collars, with a common standardheight of 200 mm and 400 mm. This European Standard is based on existing national standards forgeneral purpose pallet collars made of timber and primarily valid for such collars. Following requirementsby users, a new category for lighter loads has been introduced - Light duty pallet collars. These arerequired to pass a lower test requirement than the general purpose pallet collars.A large amount of knowledge exists from a long experience in the use of pallet collars. Where productstandards exist, it may not be necessary to have verification of performance by testing.Annex A shows commonly used dimensions for reusable general purpose pallet collars.Annex B shows the suitable plywood quality for pallet collars.For pallet collars in other materials, strength requirements according to this standard can be used but itshould be presupposed that such constructions can require special testing or conditioning.SIST EN 13545:2002

EN 13545:2002 (E)51 ScopeThis European Standard specifies test methods and performance requirements for reusable wooden andwoodbased pallet collars. There are two categories of construction:i) - class 1: general purpose pallet collars;ii) - class 2: light duty pallet collars.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 314-2, Plywood — Bonding quality — Part 2: Requirements.ISO 3130, Wood — Determination of moisture content for physical and mechanical tests.prEN 13183-1, Round and sawn timber — Method of measurement of moisture content — Part 1: Method fordetermining moisture content of a piece of sawn timber (Oven-dry method).prEN 13183-2, Round and sawn timber — Method of measurement of moisture content — Part 2: Method fordetermining moisture content of a piece of sawn timber (Electrical method).3 Conditioning3.1At manufacturing and testing of wooden pallet collars the moisture content shall be 14 % - 20 % of the weightof the timber in the anhydrous state. In connection with the test, the moisture content of the timber shall bedetermined before and after the test.3.2The testing shall be carried out at a temperature of 20 °C ± 5 °C. The pallet collars and the pallets shall bekept in the test atmosphere for at least 48 h before testing.4 Apparatus4.1Testing machine capable of applying load in vertical and/or horizontal direction and with a measuringaccuracy of ± 3 %.4.2The accuracy of positioning of components shall be within ± 2 mm.4.3Devices to have the pallets secured for test 6.3 and 6.5.4.4Instrument for measuring deformation with an accuracy of 0,2 mm.4.5Determination of moisture content in accordance with ISO 3130, prEN 13183-1 and prEN 13183-2.5 Procedure5.1Carry out the tests either at a constant rate of loading of (2 ± 0,2) kN/min, or constant speed of the testingmachine loading head of (30± 5) mm/min.5.2In connection with the tests, the moisture content of the timber shall be recorded.SIST EN 13545:2002

EN 13545:2002 (E)65.3The pallet collars tested shall be discarded after every test.6 Testing6.1 GeneralTests shall be conducted as follows:1. bending stiffness and strength;2. tensile testing of hinge and rivet joint (not applicable to pallet collars with rigid corner bars);3. shear loading of supporting lips;4. load testing of stacked pallet collars.6.2 Bending stiffness and strength6.2.1 Test selectionBending stiffness and strength tests shall be performed on the appropriate type of pallet collar:1. rigid side pallet collars;2. folding hinged pallet collars.6.2.2 Test 1a — Bending stiffness and strength — Rigid side pallet collarsThree tests shall be performed with test pieces taken from different collar sides.6.2.3 ApparatusTest arrangement according to Figure 1a6.2.4 Testing procedureA piece of a collar side about 600 mm long is placed flat and horizontal on supports movable in the long sidedirection of the test piece.With the supports parallel two forces acting across the whole width of the test piece are applied against the testpiece.The force is transferred to the test piece by the half round steel profiles of 20 mm diameter.The plane surface shall be turned against the test piece. The half round steel profiles shall be symmetricallyplaced with a relative position to each other of 150 mm.The force is increased continuously to:for sides of 200 mmGeneral purpose pallet collars3,22 kNLight duty pallet collars1,61 kNfor sides of 400 mmGeneral purpose pallet collars6,44 kNLight duty pallet collars3,22 kNAt this force the bend at the middle of the test piece is measured. The force is then increased until the test piecebreaks.SIST EN 13545:2002
