Overview

EN ISO 16663-1:2009 (CEN adoption of ISO 16663-1:2009) specifies a standardized laboratory method for determining the mesh opening (size of the mesh opening) of fishing nets using an objective mesh gauge. The method is applicable to both active and passive fishing gear and defines the principle, apparatus, measurement forces, calibration/verification and test procedures for dry and wet testing.

Key topics and technical requirements

• Principle: An objective, electrically driven mesh gauge inserts jaws into a mesh, stretches it until a preset measurement force is reached, and records the mesh opening automatically.
• Objective mesh gauge specifications:
  • Electrically driven, automatic operation with built-in force measurement.
  • Force range 5 N to 180 N with precision 1 N; fixed forces of 10 N, 20 N, 50 N and 125 N.
  • Jaws: 2 mm thick, rounded edges radius 1 mm; measurement precision 1 mm.
  • Measurement range 10 mm to 300 mm; stretching speed (300 ± 30) mm/min.
  • Rugged, lightweight design (≤ 2.5 kg), corrosion-resistant, IP56 dust/water rating, operating −10 °C to +40 °C; storage −25 °C to +65 °C.
• Software & data:
  • Menu-driven UI, one-handed operation, integral display.
  • Stores ≥ 1 000 measurements, transmits data to a computer.
  • Computes mean mesh opening (rounded to 0.1 mm); automatic selection of longer diagonal for square meshes; saves raw measurement data for verification.
  • Automatic self-test on start-up; safe shutdown on error.
• Measurement forces:
  • Active gear: 20 N for meshes < 35 mm; 50 N for ≥ 35 mm and < 55 mm; 125 N for ≥ 55 mm.
  • Passive gear: 10 N for all mesh sizes.
• Calibration & verification:
  • Annual calibration by an authorized institute.
  • Length verification using calibrated test plate slots; force verification using calibrated weights (10, 20, 50, 125 N).
• Testing conditions:
  • Dry testing: condition specimens per ISO 139 standard atmosphere.
  • Wet testing: immerse in tap water at (20 ± 2) °C for ≥ 12 h or in wetting solution at (20 ± 2) °C for ≥ 1 h.

Applications and who uses it

• Fisheries regulators and compliance bodies verifying legal mesh sizes.
• Net manufacturers and quality-control labs ensuring consistent mesh dimensions.
• Research institutions studying selectivity and bycatch related to mesh opening.
• Certification and inspection bodies performing standardized mesh measurements.

Related standards

• ISO 139 - standard atmospheres for conditioning and testing (referenced).
• ISO 1107 - fishing nets terminology and definitions.
• IEC 60529 - degrees of protection by enclosures (IP Code) for equipment rating.

Keywords: fishing nets, mesh size, mesh opening, objective mesh gauge, ISO 16663-1:2009, measurement force, calibration, net testing, active fishing gear, passive fishing gear.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 16663-1 was prepared by Technical Committee ISO/TC 38, Textiles.
This second edition cancels and replaces the first edition (ISO 16663-1:2003), which has been technically
revised.
