11、“International Standard” wherever they appear. Cross-references. The references to other International Standards should be replaced by references to British Standards as follows: A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are
12、 responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

15、91 1 Scope and field of application The International Standard describes the principal characteristics of knotted netting for fishing nets, and specifies the items of information to be furnished when ordering the netting. It is intended to facilitate the exchange of information between purchasers an
16、d suppliers of knotted netting for fishing nets. NOTEIt should be understood that a complete designation of knotted netting and its component yarns will not always form part of a contract. There will be occasions when an order is placed on the basis of a sample or some other basis that does not give
17、 a complete indication of the properties of the netting or its component yarns. Nevertheless, it is desirable that the complete range of information should be dealt with in this International Standard so that a standard method is available for use on those occasions when it is needed. 2 References I

ISO 1107, “Fishing nets Netting Basic terms and definitions”. 3 Principal characteristics of knotted netting 3.1 Types of manufacture. Knotted netting may be manufactured in the two-yarn system or in the single-yarn system as des
19、cribed below. 3.1.1 Two-yarn system. Knotted netting consisting of two systems of yarns is mostly manufactured on a knotting machine. The yarn of one of the two systems runs like a weaving warp from bobbins, while the yarn of the other system is wound on shuttles that guide it towards a hook-shaped
20、or needle-type knotting device. All the knots in one row are knotted simultaneously. 3.1.2 Single-yarn system. Knotted netting consisting of a single-yarn system is mostly hand made. The yarn is wound on a netting needle and all the meshes in the same row are knotted individually one after another.
21、A uniform mesh size may be achieved by the use of a mesh gauge during knotting. If the netting is made as a flat panel, then the netting yarn runs alternately from left to right and from right to left. If the netting is knotted round and round (as a “tube” or “cylinder”), then the yarn proceeds cont
22、inuously in the same direction.
