‫ ( ﻣﻨﻌﻜﺲ ﻛﻨﻨﺪه دﻳﺪﮔﺎﻫﻬﺎي‬IPS ) ‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ اﻳﺮان‬

The Iranian Petroleum Standards (IPS) reflect
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
production facilities, oil refineries, chemical and
petrochemical plants, gas handling and ‫ ﺗﺄﺳﻴﺴﺎت اﻧﺘﻘﺎل و ﻓﺮاورش ﮔﺎز و ﺳﺎﻳﺮ ﺗﺄﺳﻴﺴﺎت‬،‫ﭘﺘﺮوﺷﻴﻤﻲ‬
processing installations and other such facilities. .‫ﻣﺸﺎﺑﻪ ﺗﻬﻴﻪ ﺷﺪه اﺳﺖ‬
‫ ﺑﺮاﺳﺎس اﺳﺘﺎﻧﺪاردﻫﺎي ﻗﺎﺑﻞ ﻗﺒﻮل‬،‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ‬
IPS is based on internationally acceptable
standards and includes selections from the items ‫ﺑﻴﻦاﻟﻤﻠﻠﻲ ﺗﻬﻴﻪ ﺷﺪه و ﺷﺎﻣﻞ ﮔﺰﻳﺪهﻫﺎﻳﻲ از اﺳﺘﺎﻧﺪاردﻫﺎي‬
stipulated in the referenced standards. They are ‫ ﻫﻤﭽﻨﻴﻦ ﺑﺮاﺳﺎس ﺗﺠﺮﺑﻴﺎت‬.‫ﻣﺮﺟﻊ در ﻫﺮ ﻣﻮرد ﻣﻲﺑﺎﺷﺪ‬
also supplemented by additional requirements
and/or modifications based on the experience ‫ﺻﻨﻌﺖ ﻧﻔﺖ ﻛﺸﻮر و ﻗﺎﺑﻠﻴﺖ ﺗﺄﻣﻴﻦ ﻛﺎﻻ از ﺑﺎزار داﺧﻠﻲ و ﻧﻴﺰ‬
acquired by the Iranian Petroleum Industry and ‫ ﻣﻮاردي ﺑﻄﻮر ﺗﻜﻤﻴﻠﻲ و ﻳﺎ اﺻﻼﺣﻲ در اﻳﻦ‬،‫ﺑﺮﺣﺴﺐ ﻧﻴﺎز‬
the local market availability. The options which ‫ ﻣﻮاردي از ﮔﺰﻳﻨﻪﻫﺎي ﻓﻨﻲ ﻛﻪ در‬.‫اﺳﺘﺎﻧﺪارد ﻟﺤﺎظ ﺷﺪه اﺳﺖ‬
are not specified in the text of the standards are
itemized in data sheet/s, so that, the user can ‫ﻣﺘﻦ اﺳﺘﺎﻧﺪاردﻫﺎ آورده ﻧﺸﺪه اﺳﺖ در داده ﺑﺮگﻫﺎ ﺑﺼﻮرت‬
select his appropriate preferences therein. ‫ﺷﻤﺎره ﮔﺬاري ﺷﺪه ﺑﺮاي اﺳﺘﻔﺎده ﻣﻨﺎﺳﺐ ﻛﺎرﺑﺮان آورده ﺷﺪه‬
The IPS standards are therefore expected to be .‫اﺳﺖ‬
sufficiently flexible so that the users can adapt ‫ ﺑﺸﻜﻠﻲ ﻛﺎﻣﻼً اﻧﻌﻄﺎف ﭘﺬﻳﺮ ﺗﺪوﻳﻦ ﺷﺪه‬،‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ‬
these standards to their requirements. However, .‫اﺳﺖ ﺗﺎ ﻛﺎرﺑﺮان ﺑﺘﻮاﻧﻨﺪ ﻧﻴﺎزﻫﺎي ﺧﻮد را ﺑﺎ آﻧﻬﺎ ﻣﻨﻄﺒﻖ ﻧﻤﺎﻳﻨﺪ‬
they may not cover every requirement of each
project. For such cases, an addendum to IPS ‫ﺑﺎ اﻳﻦ ﺣﺎل ﻣﻤﻜﻦ اﺳﺖ ﺗﻤﺎم ﻧﻴﺎزﻣﻨﺪيﻫﺎي ﭘﺮوژه ﻫﺎ را‬
Standard shall be prepared by the user which ‫ در اﻳﻦ ﮔﻮﻧﻪ ﻣﻮارد ﺑﺎﻳﺪ اﻟﺤﺎﻗﻴﻪاي ﻛﻪ ﻧﻴﺎزﻫﺎي‬.‫ﭘﻮﺷﺶ ﻧﺪﻫﻨﺪ‬
elaborates the particular requirements of the
user. This addendum together with the relevant ‫ اﻳﻦ‬.‫ﺧﺎص آﻧﻬﺎ را ﺗﺄﻣﻴﻦ ﻣﻲﻧﻤﺎﻳﺪ ﺗﻬﻴﻪ و ﭘﻴﻮﺳﺖ ﻧﻤﺎﻳﻨﺪ‬
IPS shall form the job specification for the ‫ ﻣﺸﺨﺼﺎت ﻓﻨﻲ آن ﭘﺮوژه‬،‫اﻟﺤﺎﻗﻴﻪ ﻫﻤﺮاه ﺑﺎ اﺳﺘﺎﻧﺪارد ﻣﺮﺑﻮﻃﻪ‬
specific project or work. .‫و ﻳﺎ ﻛﺎر ﺧﺎص را ﺗﺸﻜﻴﻞ ﺧﻮاﻫﻨﺪ داد‬
The IPS is reviewed and up-dated approximately ‫اﺳﺘﺎﻧﺪاردﻫﺎي ﻧﻔﺖ ﺗﻘﺮﻳﺒﺎً ﻫﺮ ﭘﻨﺞ ﺳﺎل ﻳﻜﺒﺎر ﻣﻮرد ﺑﺮرﺳﻲ‬
every five years. Each standards are subject to ‫ در اﻳﻦ ﺑﺮرﺳﻲﻫﺎ ﻣﻤﻜﻦ اﺳﺖ‬.‫ﻗﺮار ﮔﺮﻓﺘﻪ و روزآﻣﺪ ﻣﻲﮔﺮدﻧﺪ‬

The users of IPS are therefore requested to send
their views and comments, including any
