We Supply ISO 7850-A Compressive Creep Rigid Cellular plastics Testing Machine
This standard was last reviewed and confirmed in 2011. Therefore this version remains current.
Specifies a method for the determination of compressive creep of rigid cellular plastics under specified conditions of load, temperature, relative humidity and time.
Test specimes in form or rectangular parallelized are placed between two flat plates and the specified load is applied as follows: procedure A) at standard conditions and procedure B) at agreed conditions of temperature and time.
The difference in compressive deformation of the loaded specimen at standard atmospheric conditions and at elevated temperature after specified time shall be calculated.
- ISO 291, Plastics — Standard atmospheres for conditioning and testing.
- ISO 1923, Cellular plastics and rubbers Determination of linear dimensions.
