ISO 12230 – June 2012

20 July 2012

ISO 12230:2012 – “Polybutene-1 (PB-1) pipes – Effect of time and temperature on the expected strength”

The main changes since the previous edition are:

• New definition of PB-1 compounds PB-H (homopolymer) and PB-R (copolymers)
• New set of reference lines (coefficients and diagram)
• New table containing calculated hoop strength values
• Recalculation of hoop strength data PB-H and specifying values rounded down to one decimal place
• Clearer specification of showing conformance to the reference lines
• Conformance to the reference lines can also be shown using not failed data points running at sufficiently high hoop stress

The new standard reference line for PB-R can be downloaded in “Downloads – Analyzer – Standard reference lines”.

The new lines are included in the Line manager of Pipeson Analyzer 3.1.6.
