    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

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

    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

    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

    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.
