1. Rationale
Within F876, the definition for crosslinked polyethylene plastics contains circular references, using plastics prepared by crosslinking (curing) polyethylene compounds. The CSA B137 Technical Committee and a task group within PPI BCD have agreed to a new, expanded definition with more explanation and without circular references. That definition will be proposed for F876, and if accepted, for F412.
