International organizations, governmental and non-governmental, in liaison with IsO, also take part in the work. IsO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 3. Publication 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 part of IsO 12777 may be the subject of International Standard ISO 12777-2 was prepared by Technical Committee ISO/TC 51, Pallets for unit load method of materials handling. ISO 12777 consists of the following parts, under the general title Methods of test for pallet joints: -Part 1: Determination of bending resistance of pallet nails, other dowel-type fasteners and staples Part 2: Determination of withdrawal and head pull-through resistance of pallet nails and staples Part 3: Determination of pallet joint strength ii ISO 12777-2:2000(E) Introduction In 1988 ISO/TC 51 considered developing standard test methods for pallet joints. It became evident that the lack of characterized sufficiently to enable worthwhile progress on full joint testing. Although there were existing, or both, of the two existing commercial nail testers were better suited to the needs of pallet makers, pallet test laboratoriesandnailmanufacturers.ThisisnowISO12777-1. methods involve standard laboratory testing equipment.
