The Iranian Petroleum standards (IPS) reflect the views of the Iranian Ministry of Petroleum and are intended for use in the oil and gas production facilities, oil refineries, chemical and petrochemical plants, gas handling and processing installations and other such facilities.

2 IPS are based on internationally acceptable standards and include selections from the items stipulated in the referenced standards . They are also supplemented by additional requirements and/or modifications based on the experience acquired by the Iranian Petroleum Industry and the local market availability. The options which are not specified in the text of the standards are itemized in data sheet/s, so that, the user can select his appropriate preferences therein. The IPS standards are therefore expected to be sufficiently flexible so that the users can adapt these standards to their requirements. However, they may not cover every requirement of each project. For such cases, an addendum to IPS STANDARD shall be prepared by the user which elaborates the particular requirements of the user. This addendum together with the relevant IPS. shall form the job specification for the specific project or work.

3 The IPS is reviewed and up-dated approximately every five years. Each standards are subject to amendment or withdrawal, if required, thus the latest edition of IPS shall be applicable The users of IPS are therefore requested to send their views and comments, including any addendum prepared for particular cases to the following address. These comments and recommendations will be reviewed by the relevant technical committee and in case of approval will be incorporated in the next revision of the STANDARD . standards and Research department , Street14, North kheradmand Karimkhan Avenue, Tehran, Iran .

The STANDARD Practice Manuals titled as "Fundamental Requirements for the Project Design and ENGINEERING " is intended for convenience of use and a pattern of follow-up and also a guidance. These STANDARD ENGINEERING Practice Manuals also indicate the check points to be considered by the process engineers for assurance of fulfillment of prerequisitions at any stage in the implementation of process projects. It should be noted that these Iranian Petroleum standards (IPS), as Practice Manuals do not profess to cover all stages involved in every project, but they reflect the stages that exist in general in process projects of oil, gas and petrochemical industries of Iran. These preparation stages describe the following three main phases which can be distinguished in every project and include, but not be limited to: Phase I: Basic Design Stages (containing seven standards ).

9 Phase II: Detailed Design, ENGINEERING and Procurement Stages (containing two standards ). Phase III: Start-Up Sequence and General Commissioning Procedures (containing two standards ). The Process ENGINEERING standards of this group include the following 11 standards : STANDARD CODE STANDARD TITLE.
