We are the only line manufacturer in the world that produces all 3 line types (Nylon, FC, Braid) inhouse.
This gives us perfect control of all production steps and gapless quality control from development to shipment.

Sufix runs the most technical advanced testing labs in the fishing industry. Relentless testing, precision engineering and clear and transparent labelling gives anglers trust in our high-performance fishing lines for every application.

WE TEST:

Diameter / Diameter consistence
Tensile strength / Knot strength (Palomar-Knot)
Elongation
Roundness
Abrasion resistance
Color retention in different conditions
UV/light resistance
Water absorption and hydrophobic characteristics in salt-/freshwater conditions
Coating – material, thickness, consistancy
Microscopic pictures of surface, structure, cross-section
Impact of temperature

The Sufix line factories employ the following methods for tensile strength testing:

1. For Monofilament Lines:
1.1 Gauge Length of the Equipment
In accordance with ASTM D2256 regulations, the gauge length is set at 250 mm (measured as the distance between point A and point B).
1.2 Test Speed (the moving speed of the clamp of the tensile testing machine during the test)
In accordance with ASTM D2256 regulations, the constant rate of extension of the moving clamps set at 300 mm/min.

2. For Braided lines
2.1 Gauge Length of the Equipment
The gauge length is set at 600mm.
2.2 Test Speed (the moving speed of the clamp of the tensile testing machine during the test)
In accordance with ISO-2062 regulations, the constant rate of extension of the moving clamp is 500 mm/min.

Please remember:

Break strength ratings were measured under controlled factory conditions. Actual performance may vary depending on factors such as knot type, line wear, environmental conditions, and equipment used. Always test your line before use to ensure it meets your specific needs.
