Introduction

Fishing gear materials refer to materials that are directly used to assemble fishing gear, mainly including five major categories of products: net wires, mesh sheets, ropes, floats and sinkers:

The naming and marking of main fishing gear materials is to unify the naming principles and marking composition of five major categories of products such as net lines: The main fishing gear materials are named after Marking standards meet the requirements for common exchange and convention of fishing gear materials, promote smooth communication, reduce communication barriers, and promote production and trade:

The smooth progress of business, scientific research and other activities: Net cable, mesh, rope, float and sinker products respectively belong to the five major categories of fishing gear material products: Related products the scale of the industry is huge and is generally processed and sold by different enterprises: Therefore, it is necessary to formulate relevant standards on a part-by-part basis to provide information for the development of modern fisheries:

Technology support: The high-quality development of fisheries requires corresponding fishing gear and material standardization systems to support it: GB/T 3939 "Main Fishing Gear Materials" "Names and Marks" aims to standardize the naming and marking of five major categories of fishing gear material products, including netting lines, to facilitate the supervision, production, trade and cooperation of related products:

For communication, etc:, it is planned to be composed of five parts:

---Part 1: Network cable:

---Part 2: Mesh:

---Part 3: Rope:

---Part 4: Float:

---Part 5: Shen Zi:

Naming and marking of main fishing gear materials Part 1: Network Cable

1 Scope

This document defines the terms and definitions of net lines, the main materials of fishing gear, and establishes the principles for naming fishing net lines and the composition of markings:

This document applies to the production, trade and management of fishing net lines: Use other network cables for reference:
