8.1 All systems that are not an epoxy-based system
applied according to table 1 of
this Standard are defined as an alternative system.
8.2 This Standard is based on recognized and commonly
used coating systems. It is not meant to exclude other, alternative,
systems with proven equivalent performance, for example non-epoxy-based
systems.
8.3 Acceptance of alternative systems shall be
subject to documented evidence that they ensure a corrosion prevention
performance at least equivalent to that indicated in this Standard,
by either:
-
.1 testing according to this standard; or
-
.2 five years' field exposure with documentary
evidence of continuous trading with crude oil cargoes.footnote The coating condition is not less than
"GOOD" after five years.
