The Iranian Petroleum Standards (IPS) reflect ‫( ﻣﻨﻌﻜﺲ ﻛﻨﻨﺪه دﻳﺪﮔﺎﻫﻬﺎي‬IPS) ‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ اﻳﺮان‬
the views of the Iranian Ministry of Petroleum ‫وزارت ﻧﻔﺖ اﻳﺮان اﺳﺖ و ﺑﺮاي اﺳﺘﻔﺎده در ﺗﺄﺳﻴﺴﺎت ﺗﻮﻟﻴﺪ‬
and are intended for use in the oil and gas
‫ واﺣﺪﻫﺎي ﺷﻴﻤﻴﺎﻳﻲ و‬،‫ ﭘﺎﻻﻳﺸﮕﺎﻫﻬﺎي ﻧﻔﺖ‬،‫ﻧﻔﺖ و ﮔﺎز‬

processing installations and other such facilities. .‫ﻣﺸﺎﺑﻪ ﺗﻬﻴﻪ ﺷﺪه اﺳﺖ‬
IPS is based on internationally acceptable ‫ ﺑﺮاﺳﺎس اﺳﺘﺎﻧﺪاردﻫﺎي ﻗﺎﺑﻞ ﻗﺒﻮل‬،‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ‬
standards and includes selections from the items ‫ﺑﻴﻦاﻟﻤﻠﻠﻲ ﺗﻬﻴﻪ ﺷﺪه و ﺷﺎﻣﻞ ﮔﺰﻳﺪهﻫﺎﻳﻲ از اﺳﺘﺎﻧﺪاردﻫﺎي‬
stipulated in the referenced standards. They are
also supplemented by additional requirements ‫ ﻫﻤﭽﻨﻴﻦ ﺑﺮاﺳﺎس ﺗﺠﺮﺑﻴﺎت‬.‫ﻣﺮﺟﻊ در ﻫﺮ ﻣﻮرد ﻣﻲﺑﺎﺷﺪ‬
and/or modifications based on the experience ‫ﺻﻨﻌﺖ ﻧﻔﺖ ﻛﺸﻮر و ﻗﺎﺑﻠﻴﺖ ﺗﺄﻣﻴﻦ ﻛﺎﻻ از ﺑﺎزار داﺧﻠﻲ و ﻧﻴﺰ‬
