Abstract:	A buried plastic pipe undergoes deformation, but it stabilizes at the end of a certain time not exceeding two years.Thus, there is an interest in determining the extrapolated creep of structured wall plastic pipes at 2 years.The main goal of this work is to present information regarding the assessment of results and their accuracy, based both on the requirements of the product standard [3] and on the uncertainty of the tests.

Keywords:	Creep Polyethylene Polypropylene Non-pressure pipes Buried pipes Structured-wall piping systems Type B
