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.

3 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.
