BS EN 12280-3 is an international standard that focuses on testing methods of rubber or plastic-coated fabrics.
BS EN 12280-3 specifies a method for the determination of light or weathering accelerated ageing effects on the physical properties of coated fabrics. It describes the testing methods for accelerated ageing and the effect of light or weathering.
BS EN 12280-3 applies to all coated fabrics for which it is necessary to assess the long-term resistance to hydrolysis which can result from exposure to warm atmospheres with high moisture content.
Note: BS EN 12280-3 is not recommended to evaluate materials that are immersed in water during use.
BS EN 12280-3 on environmental ageing of coated fabrics is useful for:
Ageing refers to all "slow and irreversible" changes in the properties of a material resulting from its instability, or the effects of the environment. This alteration can affect the chemical structure of the polymers or additives, the composition of the material, or its physical condition.
BS EN 12280-3 used to measure the deterioration of coated fabrics may be strength properties, flexing, blocking or any other desired physical or chemical property. By the selection of appropriate methods of testing, the physical properties can be investigated.
BS EN 12280-3 lays out a test method for examining the environmental ageing of rubber and plastic-coated fabrics. It shows the effect of humidity in combination with high temperatures. It presents you with the section on sampling and preparation of test specimens, that guides you through the bulk sampling and specimen geometry.
BS EN 12280-3 covers procedures, calculation and expression results, test reports and determination of roll characteristics.
BS EN 12280-3 involves simulations that reproduce the normal conditions of utilisation as closely as possible, but where the parameters are set so that ageing occurs more rapidly.
