The Omega gauge has a measuring range of at least 10–300 mm (0.4 inches–11.81 inches), and shall be inserted into the meshes under a pressure or pull of 125 N or 12.75 kg for mesh greater than or equal to 55 mm (2.17 inches) and under a pressure or pull of 50 N or 5.10 kg for mesh less than 55 mm (2.17 inches). Twine top mesh size is measured by using an electronic Omega gauge or a wedge-shaped gauge. The mesh in the regulated portion of the net is measured at least five meshes away from the lacings running parallel to the long axis of the net. The mesh size is the average of the measurements of any series of 20 consecutive meshes for nets having 75 or more meshes, and 10 consecutive meshes for nets having fewer than 75 meshes when using either the Omega gauge or the wedge-shaped gauge. The wedge shaped gauge, with a taper of 2 cm (0.79 inches) in 8 cm (3.15 inches) and a thickness of 2.3 mm (0.09 inches), shall be inserted into the meshes under a pressure or pull of 5 kg (11.02 lb) for mesh size less than 120 mm (4.72 inches) and under a pressure or pull of 8 kg (17.64 lb) for mesh size at, or greater than, 120 mm (4.72 inches). ![]() Mesh size is measured by using an electronic Omega gauge or a wedge-shaped gauge.
