Plastics piping and ducting systems - Thermoplastics shafts or risers for inspection chambers and manholes - Determination of ring stiffness; English version of DIN EN 14982:2006-12
This European Standard specifies a test method for assessing the initial (short-term) tangential ring stiffness of riser shafts for thermoplastics inspection chambers or manholes.
NOTE This is intended as a test of the structural integrity of riser shafts supporting product standards prEN 13598-2[1] and prEN 15229[2].
