*** This list of typical physical properties is intended for basic characterization of the material and does not represent specific determinations of
specifications. The physical properties values reported herein were determined on compression molded specimens prepared in accordance with Procedure C of ASTM D 1928 and
may differ from specimens taken from pipe.
** Tests were discontinued because no failures and no indication of stress crackinitiation.
