Overview
SIST EN ISO 1530:2003 is an international standard developed by CEN that specifies the principal characteristics and designation system for knotted netting used in fishing nets. Its primary purpose is to standardize the description and ordering information for knotted fishing net netting, facilitating clear communication and efficient exchange of information between purchasers and suppliers. This standard covers all aspects related to the manufacturing, materials, structure, and descriptive terminology of knotted netting.
By adhering to SIST EN ISO 1530:2003, stakeholders in the fishing industry can ensure consistency, improve procurement processes, and support quality control when dealing with knotted nettings for various fishing applications.
Key Topics
-
Manufacture Methods
- Two-yarn system: Machine-made, using two yarn systems with warp and shuttle yarns.
- Single-yarn system: Typically hand-made, with each mesh knotted individually.
-
Types of Knotted Netting
- Twisted mesh: Knots formed in the same direction.
- Untwisted mesh: Knots alternate direction.
-
Knots Classification
- Weaver’s knot (Z-type and S-type)
- Double weaver’s knot
- Reef knot
-
Direction of Stretch
- N-stretch: Depthwise stretch.
- T-stretch: Lengthwise stretch.
- Netting may be chemically or thermally stabilized after stretching.
-
Netting Size and Mesh Dimensions
- Defined by meshes deep (MD) and meshes long (ML).
- Mesh size specified as length of mesh side, length of mesh, or mesh opening.
- Special features include selvedge meshes, reinforcements, and markings.
-
Netting Yarns Description
- Yarn size designated per ISO 858.
- Material type specified, detailing fibre composition and yarn construction.
-
Ordering Information Exchange
- Indication of netting use (e.g., gill-nets, trawl-nets).
- Specification of manufacture method and knot type.
- Direction and stabilization of stretch.
- Netting size details.
- Yarn specifics and finish requested.
- Packaging requirements including extension direction and packaging type.
Applications
SIST EN ISO 1530:2003 is critical for manufacturers, suppliers, and purchasers involved in the fishing industry, especially where knotted netting forms an essential component of fishing gear. Its practical applications include:
- Fishing Net Production: Assisting manufacturers with standardized specifications to produce consistent, reliable knotted nets.
- Procurement and Supply Chain: Providing purchasers with a comprehensive framework to specify knotted netting requirements accurately, minimizing ordering errors.
- Quality Assurance: Enabling quality control teams to verify the netting characteristics against defined standards to ensure compliance.
- Design of Fishing Gear: Supporting gear designers by clarifying the types of netting and knot configurations best suited for various fishing methods.
By applying this standard, the fishing industry benefits from improved product uniformity, enhanced communication, and streamlined logistics for knotted netting materials.
