GB/T3939 "Naming and marking of main fishing gear materials" is divided into the following five parts: GB/T3939.1-2004 "Naming and marking of main fishing gear materials - net line"; GB/T3939.2-2004 "Naming and marking of main fishing gear materials - net sheet"; GB/T3939.3-2004 "Naming and marking of main fishing gear materials - rope"; GB/T3939.4-2004 "Naming and marking of main fishing gear materials - float"; -GB/T3939.5-2004 "Naming and marking of main fishing gear materials - sinker". This part is Part 1 of GB/T3939.
GB/T3939.1—2004
This part is a revision of GB/T3939—1983 "Netting Line Marking". Its important technical contents are as follows: The name of the first part is changed from "Netting Line Marking" to "Naming and Marking of Main Fishing Gear Materials Netting Line": - Add the naming part, and complete the marking into a mark; - Omit the unit symbol in the mark;
Simple marking is expanded from picking up twisted wire to monofilament and braided wire; - When twisted wire is simply marked, in addition to being expressed by comprehensive line density, it can also be expressed by structure. This part uses the definitions in SC/T5001 "Basic Terms of Fishing Gear Materials". This part is proposed by the Fisheries Bureau of the Ministry of Agriculture.
This part is under the jurisdiction of the Technical Committee on Fishing Gear and Fishing Gear Materials of the National Technical Committee for Aquatic Products Standardization (TC156/SC4). Drafting units of this part: East China Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Shandong Marine Fisheries Research Institute. The main drafters of this part are Chai Xiufang, Le Weizhang and Zou Benquan. The East China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences is entrusted with the interpretation of this part. The previous versions of the standards replaced by this part are: -GB/T3939-1983.
1 Scope
Naming and marking of main fishing gear materials
This part of GB/T3939 specifies the naming principles and marking composition of net lines. GB/T3939.1-2004
This part is applicable to the naming and marking of net lines that have not been treated in any way. If the net lines that have been treated chemically or physically are marked with comprehensive line density, it must be indicated.
2 Normative references
The provisions in the following documents become the provisions of this part through reference in this part of GB/T3939. For any dated reference, all subsequent amendments (excluding errata) or revisions are not applicable to this part. However, parties to an agreement based on this part are encouraged to study whether the latest versions of these documents can be used. For any undated reference, the latest version applies to this part.
SC/T5001 Basic terms of fishing gear materials
3 Terms and definitions
Terms and definitions established in SC/T5001 apply to this part of GB/T3939. 4 Naming
Netting cables are named according to the principle of classification of fiber materials. 4.1 When the netting cable is composed of a single fiber material, the Chinese name of the fiber material is followed by the word "netting cable" as the product name. 4.2 When the netting cable is composed of two or more fiber materials, the Chinese name of the fiber material is written in order of priority and followed by the word "netting cable" as the product name.
4.3 When the netting cable structure is a single-filament type, the Chinese name of the fiber material is followed by the word "monofilament" as the product name. 5 Monofilament marking
5.1 The monofilament marking shall include the following four items in order: a) product name;
b) nominal diameter of the monofilament, expressed in millimeters; c) linear density of the monofilament, expressed in tex; d) standard number.
5.2 Leave a space between a) and the latter item and between d) and the former item.5.3b) "@" shall be written before the value of the nominal diameter. c) "px" shall be written before the value of the linear density. Example: Fishing nylon 6 monofilament @0.40px150SC5004 This means that the fishing nylon 6 monofilament with a nominal diameter of 0.40mm and a linear density of 150tex produced in accordance with SC5004 "Fishing nylon 6 monofilament" is produced. 6 Twisted yarn marking
6.1 Twisted yarn marking shall include the following eight items in order: a) product name;
b) linear density of monofilament or single yarn, expressed in tex value; c) number of monofilaments or single yarns after primary twisting;1
GB/T 3939.1--2004
d) number of strands of double-twisted yarn after double twisting;
e) number of strands of composite twisted yarn after composite twisting;
f) comprehensive linear density, expressed in tex value; g) final twist direction of finished product, expressed in "S\" or "Z"; h) standard number.
6.2 Leave a space between a) and b) and between h) and the previous item.6.3b) "αx" shall be written before the numerical value of linear density. b)~e) are connected by "×". 6.4 If the net line is a single twist line, there is no d) and e); if it is a double twist line, there is no e). 6.5f) "R" should be written before the value of the comprehensive linear density. 6.6 When the final twist direction of the finished product is Z twist, the g) feature can be omitted. Example 1: Nylon fishing net line Px23×3R75SSC5006 means a single twist line with a comprehensive linear density of 75tex and a final twist direction of S, produced according to SC5006 "Nylon Fishing Net Line", which is made by twisting 3 nylon multifilaments with a linear density of 23tex at one time.
Example 2: Nylon fishing net line Px23×6×3R460SC5006 means a double twist line with a final twist direction of B, produced according to SC5006 "Nylon Fishing Net Line", which is made by twisting 6 nylon multifilaments with a linear density of 23tex into strands, and then twisting 3 strands into a comprehensive linear density of 460tex.
Example 3: Polyethylene fishing net line p36×6×3×3R2140SC5007 means that it is produced according to SC5007 "Polyethylene fishing net line", with 6 polyethylene monofilaments with a linear density of 36tex twisted into strands, then 3 strands twisted into a double-twisted yarn, and finally 3 double strands twisted into a composite twisted yarn with a comprehensive linear density of 2140tex and a final twist direction of Z. 7 Braided wire marking
www.bzxz.net7.1 Braided wire marking shall include the following three items in order: a) product name;
b) comprehensive linear density, expressed in tex value; c) standard number.
7.2 Leave a space between a) and b) and between b) and c). 7.3b) "R" shall be written before the value of the comprehensive linear density. 8 Simple marking
8.1 Simple marking may be used when comprehensive marking is too complicated in situations such as product marking, fishing gear mapping, net marking, and net cables made of different materials.
8.2a) The product name is represented by the fiber material code followed by a "-". There is no space between a) and the following item. When the network cable is composed of two or more fiber materials, the fiber material codes are connected by a "". 8.3 When the single filament is simply marked, b) of Chapter 5 is omitted or c) is omitted. Example: The example of Chapter 5 is simply marked as: PA6-px150SC5004
or
[email protected]8.4 When the twisted yarn is simply marked, b)~e) of Chapter 6 is omitted or the total number of single filaments (single yarns) is used to replace c)~e) and f) is omitted. Example: Example 3 of Chapter 6 is simply marked as: PE-R2140SC 5007
or PE-P36×54SC5007
