Shear Strength Test Methods
Shear Strength | Type | Cure Time | Substrate | Test Time | Test Temperature | Test Method |
---|---|---|---|---|---|---|
High | ||||||
80 psi | Dynamic overlap shear strength | 4,320 min | Stainless steel | 25°C | ASTM D-1002 - To stainless steel, room temperature, 1 in2 (6.45 cm2), jaw speed 0.5 in/min (12.7 mm/min.) Peak force to separate is measured. 72 hour dwell. | |
1000 (grams) | Static shear strength | Stainless steel | 604,800 sec | 22°C | ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2. | |
500 (grams) | Static shear strength | Stainless steel | 604,800 sec | 66°C | ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2. | |
500 (grams) | Static shear strength | Stainless steel | 604,800 sec | 93°C | ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in2 (3.22 cm2). Will hold listed weight for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in2 equals 6.6 lb/in2, 500 g/0.5 in2 = 2.2 lb/in2. |
