6.2.1 Oil content meters which in every respect
fulfil the requirements of these Guidelines and Specifications may
be approved by the Administration for fitting on board tankers. The
approval should take the form of a certificate of type approval specifying
the main particulars of the apparatus and any limiting conditions
on its usage necessary to ensure its proper performance. Such certificate
should be issued in the format shown in part 3 of the Annex to these
Guidelines and Specifications. A copy of the certificate of type approval
for the oil content meter should be carried aboard an oil tanker fitted
with such an equipment at all times.
6.2.2 A certificate of type approval should be
issued for the specific application for which the oil content meter
is approved, i.e. for crude oil, “black” products, “white”
products, other products or applications as listed on the certificate.
6.2.3 Approved oil content meters may be accepted
by other countries for use on their vessels on the basis of the first
trials, or after new tests carried out under the supervision of their
own representatives. Should an oil content meter pass a test in one
country but fail a test of a similar nature in another country, then
the two countries concerned should consult one another with a view
to reaching a mutually acceptable agreement.
