Unplasticized polyamide (PA-U) pipes. Effect of time and temperature on the expected strength

1 Scope

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-U 180) extruded pipes.

NOTE 1 PA-U 180 follows ISO 16486‑1 in terms of minimum strength values and covers both PA-U11 180 and PA-U12 180.

NOTE 2 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.

BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
