Unplasticized polyamide (PA-U) pipes - Effect of time and temperature on the expected strength
This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on unplasticized polyamide (PA-UÂ 180) extruded pipes.
NOTE 1Â Â Â Â Â Â Â PA-U 180 follows ISOÂ 16486-1 in terms of minimum strength values and covers both PA-U11Â 180 and PA-U12 180.
NOTE 2Â Â Â Â Â Â Â As there is not test data available for other types of polyamide (e.g. PA-U 160) this document does not currently contain appropriate reference lines for these materials. Future revisions will include other types of polyamide when sufficient test data becomes available.
