- Breaking Strength of Fabrics (Grab Method: CAN/GSB-4.2 Method 9.2-M90)
This test is similar to ISO 5082:1982
A 4″ wide x 6″ tall specimen of fabric is held between 2 vertical clamps. Tension is applied so that rupture of the specimen occurs within 20 seconds. - Breaking Strength of Yarns (Single Strand Method: CAN/GSB-4.2 Method 9.4-M91)
A single strand of yarn is held between 2 clamps. Tension is applied so that rupture of the specimen occurs within a specified interval of time. - Burst Strength (Diaphragm Pressure Test: CAN/GSB-4.2 Method 11.1-94)
This test is technically equivalent to ASTM D 3786-87.
A fixed area of fabric is subjected to pressure on one side through a diaphragm, and the pressure is gradually increased until the fabric is ruptured. - Wounded Burst Strength (Diaphragm Pressure Test: CAN/GSB-4.2 Method 11.1-94)
Same as previous except a 12.5 mm cut is made to the test area.

Video
The video below shows the 6 tests being performed on the White High Strength Net.
Drop tests were conducted in 2008 on 2 panels of stock net (black and white). The drop was 20 feet and the panel measured 12′ x 25′. The drop was made over the center of the net using an assembled piece of wood weighing 15 lb.
Black Net
The chunk of wood broke through the net after 2 drops.
White Net
No damage to the net after 5 drops. A 6th test was performed using a 55 lb cast iron weight with no damage to the white net.
