9、9)E( ISO 2002 r llAithgs reservde iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body
10、 interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotec
11、hnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publ
12、ication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or al
13、l such patent rights. International Standard ISO 15629 was prepared by Technical Committee ISO/TC 51, Pallets for unit load method of materials handling.

14、troduction Efficient international transportation of products depends on both pallet strength and functionality, or fit, to the materials handling systems. Existing ISO standards address issues of strength and some issues regarding functionality of pallets. However, major issues related to the minim
15、um material quality and manufacturing and repair workmanship are not addressed in current ISO standards. These factors may significantly impact the efficiency of international unit-load material handling. In November, 1996, ISO TC 51 approved a new work item “Timber Pallets for Materials Handling Qu
16、ality of Component Assembly and Repair” and established WG 7 to prepare a document. This International Standard contains recommended minimum acceptable quality levels for mechanical fasteners used in the assembly of wooden pallets. Mechanical fasteners commonly used for the assembly of wooden pallet
17、s are classified as nails, staples, bolts and screws. The type and properties of fasteners affect pallet performance. This International Standard does not address safety problems, if any, associated with the use of these fasteners. It is the responsibility of the user of this International Standard
18、to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. This document addresses the current commercial difficulty in pallet manufacture, that there is no recognized means of defining pallet nails with regard to their quality and st
19、rength. Table 2 gives a guide as to strength qualities for nails which are typically used in construction of very strong pallets as opposed to pallets designed for light loads. Actual nail diameter, profiles and strengths are the responsibility of the specifier and user who may find the full-scale p

22、 Quality of fasteners for assembly of new and repair of used, flat, wooden pallets 1 Scope This International Standard gives guidelines on nails and staples used in the assembly of new and repair of used wooden flat pallets. For the purposes of this International Standard the term fasteners applies
23、to nails and staples only. This International Standard is prescriptive and performance-based and contains physical descriptions of fasteners as well as minimum recommended performance levels. For information on other fasteners such as bolts and screws used in pallets, see ISO 445. 2 Normative refere
24、nces The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this
25、 International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently vali
26、d International Standards.

27、drawal and head pull-through resistance of pallet nails and staples 3 Terms and definitions For the purposes of this International Standard, the terms and definitions given in ISO 445 apply together with the following. 3.1 fluted nail round wire nail with thread-crests parallel to the nail shank 4 N
28、ails and Staples 4.1 Classification As used in pallets, nails are classified as plain- or smooth-shank, helical, annular ring, twisted or barbed. Staples have either round-wire or approximately square-wire legs, referring to the cross-sectional shape of the wire. Nails and staples shall be specified
29、 using at least nail wire diameter, length, thread type and point type. These and other characteristics which affect pallet nail and staple performance are listed in Table 1.

30、ring the physical characteristics of nails and staples are described in annex A. When a complete assessment of fastener quality is required, separation resistance in accordance with ISO12777-2 shall be determined by measuring both fastener shank withdrawal and head or crown pull-through. These tests
31、 shall include using wood specimens and specimen conditioning typical of those which occur during pallet use. 4.3 Minimum acceptable performance The recommended minimum acceptable performance levels for nails and staples are specified in Table 2. Annex B is a correlation between the static bending r
32、esistance values reported in Table 2 and the MIBANT impact bend test as described in ISO 12777-1. NOTE 1 Tests of joints containing multiple fasteners are described in ISO 12777-3. NOTE 2 Pallet fasteners are sometimes coated. These coatings are intended to: increase corrosion resistance; improve se
33、paration resistance; improve drivability. The effect of coatings on fastener performance shall be evaluated using tests described in ISO 12777-2.

A.3 Thread length The thread length ( ) is the continuous distance from the top end of the thread along
44、the nail shank to the top of the point or the bottom end of the thread, as shown in Figure A.3. If the thread is not continuous, i.e. interrupted, the thread length is the length of the threaded portions of the nail shank penetrating the nailing member to the required depth.
