Description des essais (en anglais) :
- Force de la rupture des tissus (Grab Method: CAN/GSB-4.2 Method 9.2-M90). 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. This test is similar to ISO 5082:1982.
- Force de la rupture de la laine (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.
- Force de l’éclatement (Diaphragm Pressure Test: CAN/GSB-4.2 Method 11.1-94). 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. This test is technically equivalent to ASTM D 3786-87.
- Force d’un éclatement délibéré (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.
