The work of preparing International Sta
19、ndards is normally carried out through ISO technical committees. 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
20、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/IEC Directives, Part 2. The main task of technical committees
21、 is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibi
22、lity that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16663-1 was prepared by Technical Committee ISO/TC 38, Textiles. This second edition cancels and replaces the first edition (ISO 1
23、6663-1:2003), which has been technically revised.

25、pening of fishing nets, using an objective mesh gauge. It is applicable to active and passive fishing gear. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、or the purposes of this document, the following terms and definitions apply. 3.1 active fishing gear fishing gear requiring movement to catch the fish NOTE In general, mobile fishing equipment (i.e. equipment which is mobile relative to the sea bed or to the water) is led into the path of the fish t
28、o pursue and catch them. All trawls, dredges, seine nets, purse seines and other surrounding nets are examples of active gear. 3.2 trawl towed net consisting of a cone-shaped body closed at the rear by a bag or cod end and widened at the opening by wings NOTE A trawl may be towed by one or two boats
29、 and, depending on the type, is used on the bottom or as a midwater (pelagic) trawl. 3.3 Danish seine funnel-shaped net (with wings and cod end) with very long ropes laid out on the sea bed and hauled in to a vessel in the open sea Licensed CopyChinese University of Hong Kong, 13/06/2009 08:01, Unco

31、 movement of the fish in order for the fish to be caught NOTE This gear is usually stationary equipment, often, but not always, anchored on the sea bed. Gill nets and entangling nets are examples of passive gear. 3.6 gill net panel of netting, usually of rectangular shape, made of thin twine or mono
32、filament yarn, in the meshes of which the fish are caught NOTE The net is suspended vertically in the water by floats and sinkers. 3.7 entangling net loosely hung vertical net that catches fish by entangling rather than enmeshing them 3.8 trammel net bottom-set net which is made up of of three walls
33、 of netting, the two tightly hung outer walls having a larger mesh size than the inner wall which is loosely hung between them NOTE The fish pass through one of the outer walls and become entangled in the small meshes of the inner wall, after which they push themselves into the second outer wall, th
34、us forming a bag. 4 Principle An objective mesh gauge is inserted into the mesh opening. The mesh is stretched by a movable jaw until a pre-set measurement force is reached. The size of the mesh opening is then measured automatically. 5 Apparatus 5.1 Objective mesh gauge, complying with the requirem
35、ents of 5.1.1 to 5.1.6. 5.1.1 The objective mesh gauge used for determining mesh openings shall be automatic and electrically driven (see Figure 1). The gauge shall be able to apply selected longitudinal measuring forces, in the range 5 N to 180 N, to the meshes with a precision of 1 N. Fixed measur
36、ing forces of 10 N, 20 N, 50 N and 125 N shall be provided. A built-in system for measuring the applied force is needed. The gauge shall have two jaws, one fixed and one movable, each 2 mm thick with rounded edges with a radius of 1 mm, to ensure that the jaws slip easily over the twine or yarn. A m
37、esh shall be stretched at a constant speed of (300 30) mm/min by the movable jaw. The gauge shall be able to measure meshes from 10 mm to 300 mm and may have different, detachable, jaws for use on small and large meshes. The measurement precision shall be 1 mm. 5.1.2 The structure of the gauge shall
38、 be rigid and shall not distort under load. The body shall be light yet robust and shall weigh no more than 2,5 kg. The gauge shall be made of materials resistant to corrosion under marine conditions. It shall be water-resistant, be unaffected by dust to rating IP 56 as specified in IEC 60529, and b
39、e stable in operation over the temperature range 10 C to + 40 C. The gauge shall be able to withstand temperatures between 25 C and + 65 C during storage and transportation.

40、2009(E) ISO 2009 All rights reserved 3 5.1.3 Gauge operation shall be controlled by software that provides a menu of functions. It shall be possible to operate the gauge with one hand and the functions shall be accessible via external buttons. Data shall be shown on an integral display able to prese
41、nt each measurement, the number of measurements made in a series and the mean value. A store shall be provided capable of holding at least 1 000 measurements and it shall be possible to transmit data to a computer. 5.1.4 The software menu shall contain a suitable function to calculate the mean mesh
42、opening, rounded to the nearest 0,1 mm. For so-called “square” meshes, the software shall contain a suitable function to select automatically the longer diagonal of each mesh to calculate the mean mesh opening of the square mesh netting. To allow verification of the selection procedure, the data sav
43、ed shall include all the measurements made. 5.1.5 The software shall permit automatic self-testing of the electronic and mechanical parts when the gauge is started. If the gauge is ready for use, this shall be shown on the display. If this is not the case, the display shall show an error message and
44、 the gauge shall close down and not be usable. 5.1.6 Some netting will creep under load. The gauge shall respond to this condition by re-applying the pre- set measurement force in accordance with an algorithm in the controlling software which causes the gauge to a) extend the movable jaw into the me
45、sh at a constant speed of (300 30) mm/min until the pre-set measurement force is reached; b) stop the motor and wait 1 s; c) if the force drops below 80 % of the measurement force, extend the jaw into the mesh until the measurement force is reached once more.

For the netting of passive fishing gear, use 10 N for all mesh sizes. 7 Calibration The objective mesh gauge shall be
48、 calibrated once a year by an authorized calibration institute. 8 Verification of length and force measurement 8.1 Verification of length measurement Verification of the length measurement shall be performed at intervals by inserting the jaws of the gauge into slots of different lengths in a calibra
49、ted rigid test plate. An example of such a test plate is shown in Figure 2.
