Full title and description

St ISO 16663-1-2009 — Fishing nets — Method of test for the determination of mesh size — Part 1: Opening of mesh. This International Standard specifies an objective test method using a mesh gauge to determine the size of the mesh opening of fishing nets; it is intended for application to both active and passive fishing gear.

Abstract

ISO 16663-1:2009 defines the procedure, apparatus and reporting requirements for measuring the opening of a mesh in fishing nets using an objective mesh gauge. The method standardizes sample preparation, gauge placement and reading conventions so mesh-size determinations are reproducible and comparable between laboratories and manufacturers.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.150 (Fishing and fishery products / Fishing gear).
• Edition / version: Edition 2 (2009).
• Number of pages: 8 pages (official ISO edition).

Scope

This part of ISO 16663 specifies a test method for the determination of mesh opening size of fishing nets using an objective mesh gauge. It applies to both active and passive fishing gear and is intended to provide a consistent, repeatable measurement procedure for manufacturers, testing laboratories and regulatory bodies assessing compliance with mesh-size requirements. The standard does not cover measurement of mesh length (addressed in a separate part).

Key topics and requirements

• Definition of mesh opening and terminology for mesh-size measurement.
• Specification of the objective mesh gauge (shape, dimensions and calibration requirements).
• Sample selection and preparation procedures to ensure representative measurements.
• Step-by-step measurement procedure: gauge placement, reading technique and number of measurements per sample.
• Calculation and reporting of results, including rounding conventions and reporting units.
• Applicability notes for different net materials and knot/mesh constructions.

Typical use and users

Used by fishing-net manufacturers, quality control and test laboratories, fisheries managers, regulatory authorities and research institutions to determine and document mesh opening sizes for product specification, type-approval, compliance testing and scientific studies of gear selectivity and bycatch reduction.

Related standards

ISO 16663 is a multi-part series on mesh-size measurement. The most directly related document is ISO 16663-2 (Part 2: Length of mesh), which specifies the complementary method for measuring mesh length. National and regional adoptions and identical standards (for example EN/BS/DIN national versions) exist for Part 1. Users should consult Part 2 and any applicable regional adoptions for complete measurement guidance.

FAQ

Q: What is this standard?

A: ISO 16663-1:2009 is an international test method that specifies how to measure the opening of a mesh in fishing nets using an objective mesh gauge.

Q: What does it cover?

A: It covers the apparatus, sample preparation, measurement procedure and reporting conventions needed to determine mesh opening size for fishing nets; it is intended for both active and passive gear.

Q: Who typically uses it?

A: Net manufacturers, testing and calibration laboratories, fisheries managers, regulators and researchers use this standard for product specification, compliance testing and scientific studies.

Q: Is it current or superseded?

A: ISO 16663-1:2009 is the confirmed second edition published in March 2009 and, according to ISO’s published lifecycle information, was reviewed and confirmed (remains current) during the ISO systematic review process. Users should verify national adoption status for local regulatory use.

Q: Is it part of a series?

A: Yes — ISO 16663 is a multi-part series on mesh-size test methods. Part 2 covers mesh length (ISO 16663-2:2003 and subsequent corrections/adoptions). Consult the series when both opening and length measurements are required.
