IPS-E-PR-200 is a basic-engineering design-data standard, not a boiler operating manual or a site-specific water-treatment specification. It describes the project information to document for applicable water services—including boiler feed water—and the conditions at utility boundaries and equipment. The indexed copy reports an original edition from March 1996 and a technical committee review and update in January 2002; its current official revision status is not established by the available third-party reproductions.
What IPS-E-PR-200 covers
Attributed in its ownership notice to the Iranian Ministry of Petroleum, IPS-E-PR-200 sets minimum content and organization for Basic Engineering Design Data (BEDD) during basic design. It establishes a consistent project-wide basis for facilities and operating cases, including utilities such as water, steam, power, fuels and air. The reproduced document states, “This Standard is the property of Iranian Ministry of Petroleum.”
For construction and project teams, the practical use is as a design-data checklist: identify applicable services, record their operating and design conditions, and make the project’s operating cases explicit. It does not prescribe universal boiler-water targets or provide a completed analysis for a particular site.
Which water services to include
List each service that applies to the project. The standard identifies these water services:

- High-pressure and medium-pressure boiler feed water
- Cooling-water supply and return
- Raw water and plant or service water
- Drinking water and fire water
- Demineralized water and desalinated water
Not every project will use every service. The BEDD should make applicability clear rather than imply that one generic water description covers distinct systems.
What conditions to record for each service
Battery-limit conditions
Record the process or utility conditions at producer and consumer battery limits, expressed in terms of pressure and temperature. Where required, provide minimum, normal and maximum values. These boundary conditions describe what the supplying facility delivers and what the receiving facility must accommodate; they are not interchangeable with the mechanical design limits of downstream equipment.
Equipment mechanical design conditions
For applicable equipment, state design pressure and design temperature. The standard’s examples include piping, vessels and exchangers, turbines, and compressors or pumps. Keep these mechanical design conditions distinct from the normal or range of utility conditions at the battery limit.
Cooling-water and cooling-tower notes
For cooling systems, document allowable pressure drop for coolers, condensers and machinery-cooling equipment, as applicable. Record the maximum cooling-water return temperature used for the cooling-tower design case. Include relevant cooling-tower design conditions such as wet-bulb temperature, treatment system, cycles of concentration and filtration.
How to organize the water specification
For circulating cooling water, cooling-tower makeup, raw water or seawater, and treated boiler feed water where applicable, the standard calls for a water-specification table. Its fields provide a structured profile of source, return and water quality; they are not target values supplied by the standard.
| Group | Specification fields |
|---|---|
| Stream and supply | Source and return; availability and value |
| Acidity and hardness | pH; total hardness; calcium; magnesium; total alkalinity |
| Dissolved ions | Sodium; potassium; sulfate; chloride; nitrate |
| Silica, iron and solids | Silica; total iron; suspended solids; dissolved solids |
| Other quality indicators | COD and other applicable characteristics |
The reproduced tables are templates, not populated analyses for a particular plant or water source. Project teams need the applicable source data and project criteria to complete the entries; no universal chemistry limits can be inferred from the blank fields.

IPS-E-PR-200 identifies operating cases to consider as required: normal, peak, block, startup, emergency, shutdown and reduced operation. The selected cases form the design basis for facilities, including utility facilities, and should be defined precisely in the project design criteria.
Apply this logic across three dimensions so the data can be checked consistently:

What the PDF does—and does not—establish
The indexed reproductions describe the expected BEDD content and include example or blank utility tables. They do not provide measurements for a named plant, a boiler-water treatment recipe, or universally valid operating and chemistry values. The surfaced copies are hosted by Scribd rather than a Ministry-controlled publication page. Before relying on the document contractually, confirm the applicable official revision with the project owner or relevant standards authority.
