Fishing gear materials refer to the materials used directly to assemble fishing gear, mainly including five categories of products. fishing line, netting, rope, floats, and sinkers. The naming and labeling of major fishing gear materials is to standardize the naming principles and labeling composition of five major product categories, including fishing lines. The marking standards meet the requirements for common exchange and convention regarding fishing gear materials, promote smooth communication, reduce communication barriers, and facilitate production and trade. The smooth progress of activities such as fishing, research, and other related activities. Netting, netting sheets, ropes, floats, and sinkers belong to five major categories of fishing gear materials, and related products... The industry is enormous, and products are generally processed and sold by different companies. Therefore, it is necessary to develop relevant standards for different sectors to provide support for the development of modern fisheries. Technological support. High-quality development of fisheries requires a corresponding standardization system for fishing gear materials. GB/T 3939 "Main Fishing Gear Materials" The "Naming and Marking Standard" aims to standardize the naming and marking of five major categories of fishing gear materials, including fishing line, to facilitate the supervision, production, trade, and cooperation of related products. The exchange, etc., is planned to consist of the following five parts.

1 Scope

GB/T 3939.4-2026 is the Chinese national standard covering how a net float is designated - the material, the shape, the buoyancy and the working depth, which for a deep-set net is the number that decides whether the float survives at all. It replaces GB/T 3939.4-2004 and has been in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, replacing GB/T 3939.4-2004. The document is under the responsibility of the Ministry of Agriculture and Rural Affairs. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document defines the terminology and definitions of fishing floats and establishes the principles and methods for naming and labeling fishing floats. This document applies to the naming and labeling of fishing foam plastic floats, rigid plastic floats, blow-molded floats, injection-molded floats, and buoys. Other For reference use of the float.

4 Naming

4.1 Naming Principles Floats are named according to the principle of classifying them by material.

4.2 Naming Method The name of a float consists of two parts. the material and the float type. The main float material codes are named according to Appendix A. The float type is determined by its shape. The spherical and cylindrical float types are named buoys and buoys respectively, while other shapes are collectively referred to as floats. When a float is made of a single material, it is named after the material name or code, followed by "float," "buoy," or "pontoon." When a float is made of two or more materials... When preparing the materials, connect the material names or codes with "/" in order of priority or outside and inside, followed by the name of the float, buoy or float cylinder.
