What is the meaning of the designations PE80 and PE100?
PE80 and PE100 meaning 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 PE100 10.0 PE80 8.0 Minimum Required Strength (MRS) 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...
How do these designations relate to MDPE and HDPE?
Prior to the adoption of international standards (CEN, ISO) PE pipe materials were more commonly designated by their density within the range associated with PE i.e. Low Density PE (LDPE), Medium Density PE (MDPE) and High Density PE (HDPE). The reference to density gave an indication of the material strength. For example HDPE pipe had a higher long term strength or minimum required strength (MRS) than LDPE. But this gave no indication as to other long term properties, such as slow crack growth...
