BS ISO 1431-1. Rubber, vulcanized or thermoplastic. Resistance to ozone cracking Part 1. Static and dynamic strain testing
|Standard number:||21/30410873 DC|
|Status:||Draft for Comment|
This standard 21/30410873 DC BS ISO 1431-1. Rubber, vulcanized or thermoplastic. Resistance to ozone cracking is classified in these ICS categories:
- 83.060 Rubber
This document specifies procedures intended for use in estimating the resistance of vulcanized or thermoplastic rubbers to cracking when exposed, under static or dynamic tensile strain, to air containing a definite concentration of ozone, at a definite temperature and, if required, at a definite relative humidity in circumstances that exclude the effects of direct light.
Visual observation and/or image analysis are used to evaluate the formation and growth of cracks. The changes in physical or chemical properties resulting from exposure may also be determined.
Reference and alternative methods for determining the ozone concentration are described in ISO 1431-3 .
