What is the meaning of the designations PE80 and PE100 ?

What is the meaning of the designations PE80 and PE100? The designations PE80 and PE100 are based on the long-term strength of the respective materials, known as the Minimum Required Strength (MRS) in accordance with ISO 12162.The designations are:


Material Designation  Minimum Required Strength (MRS)MPa
PE 100 10.0
PE 80 8.0

The MRS is determined by performing regression analysis in accordance with ISO 9080 on the test data from the results of long-term pressure testing. The regression analysis allows for the prediction of the minimum strength for a specific service lifetime. The data is extrapolated to predict the minimum strength at 20°C and at the specified 50 year design lifetime. Full details of the analysis can be found in ISO 9080 .
