In places, the text has been substantially altered including: the classification system,
13、tests for resistance against corrosion, re-written SWL test procedure, re-written section on electrical non-conductivity. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2007-
