- 83.060 Rubber
This Part of BS 5421 describes eight methods of test for polyurethane thread (elastane yarn):
| method 1 | Preparation of test specimens; |
| method 2 | Determination of mass per unit length; |
| method 3 | Determination of breaking load, tenacity and elongation at break; |
| method 4 | Determination of load at predetermined elongation; |
| method 5 | Determination of stress decay; |
| method 6 | Determination of set; |
| method 7 | Resistance to copper staining during laundering; |
| method 8 | Resistance to atmospheric fume staining. |
Preparation of test specimens; mass per unit length; breaking load, tenacity and elongation at break; load at predetermined elongation; stress decay; set; resistance to copper staining; resistance to fume staining.
