0. INTRODUCTION
This Standard is based on the combined experience of oil industry specialists in engineering, design, purchase, construction,
operation, maintenance and inspection of electrical installations in process and utility plants, and may be applied at
every oil refinery, gas establishment and petrochemical plant, thus a large measure of uniformity throughout the procurement
will be achieved with all its economic and harmonization advantages.
This standard may not cover every requirement or diversity of conditions at each locality, but this is recognized and the
write up is sufficiently flexible to allow individual companies in oil, gas, and petrochemical industries of Iran to exercise
their own judgment in these situations, with due consideration to the existing electrical installations of oil, gas and
petrochemical industries in Iran and the pertinent prevailing hazards.
It is necessary to mention also that this standard is written mainly for the purchase of transformer rectifier to be installed
in non hazardous atmospheres, and their installation shall be avoided in hazardous locations.


1. SCOPE
This Standard specification covers the minimum technical requirements for design, manufacture, quality control, finishing
and testing of indoor or outdoor transformer rectifiers which shall be installed in oil, gas and petrochemical industries
in Iran under the service conditions stated in clause 4 of this Standard specification.
Only the general requirements of transformer rectifiers are given in this standard specification, the specific requirements
of individual transformer rectifiers will be given in pertinent data sheets and or requisitions.
This standard specification shall be used for preparation of requisitions and purchase orders and subsequently as a
guideline for the manufacturer of the equipment described.
2. REFERENCES
