The work of preparing International Standards is normally carried out through ISO technical comm
11、ittees. Each member body 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
12、International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for th
13、e different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

31、hindshanks trimmed square at the hock and removed from the rump and brisker, the butt fairly shaped, and horns, tailbones and head meat removed. Heads should be trimmed by removing the mask (pates), ears and lips, leaving only the cheeks. Tails should be trimmed to not more than 300 mm. If the cheek
32、 of a hide bears a cut of more than 80 mm in length, the portion of the cheek beyond the cut should be removed by continuing the cut in both directions. 4.2 Calf skins Before being classified by weight, shanks should be trimmed short, tailbones should be removed and the skin should be without head,
33、i.e. cut off behind the ears and without cheeks. Reference may also be made to ISO 2820, which provides an optimum method of trimming. 5 Determination of mass 5.1 Raw hides and skins Weigh raw cattle hides to the nearest 0,5 kg and raw calf skins to the nearest 0,1 kg. Allowances should be made for
34、dung and flesh left on the hide or skin. 5.2 Wet salted hides and skins Open each hide or skin to be weighed. Shake it violently by hitting the flesh side and grain side one time each against the rectangular support, 300400 mm high. Remove leftover salt by brushing. Weigh wet salted cattle hides to
35、the nearest 0,5 kg and wet salted calf skins to the nearest 0,1 kg. NOTE Any mechanical methods of desalting can be utilized for the purpose. 5.3 Dry salted hides and skins Open each hide or skin to the weighed. Shake it to remove any extraneous matter. Weigh dry salted cattle hides and calf skins t
36、o the nearest 0,1 kg. 5.4 Dried hides and skins Open each hide or skin to be weighed. Shake it to remove any extraneous matter. Weigh dried cattle hides and calf skins to the nearest 0,1 kg.
