Specialized & Ad Hoc Inspection Services
### 1. Service Introduction
Iran Standard and Quality Inspection Company (ISQI) provides specialized and ad hoc inspection and technical assessment services according to project requirements, equipment conditions, and the client’s request.
These services are defined for issues that require a specific examination, selection of an appropriate inspection method, or a combination of several specialized activities, and may not fall within routine inspection programs.
The scope of work is determined after reviewing the subject, available documents, access conditions, and the purpose of the assessment, so that the results obtained address the client’s specific technical question.
### 2. Scope of Services
| Initial review of the request and definition of the technical issue |
| Review of documents, inspection records, and operational information |
| Site visit and initial assessment of equipment condition |
| Post-incident technical inspection |
| Development of a dedicated inspection scope and plan |
| Selection of test methods appropriate to the type of damage or expected discontinuity |
| Conducting local or supplementary inspection of equipment |
| Examination of damaged or repaired areas |
| Assessment of the technical condition of equipment within the agreed scope |
| Performing or supervising the required specialized tests |
| Review and correlation of inspection and test results |
| Providing recommendations for further examinations or corrective actions |
| Preparing a technical report appropriate to the project objective |
### 3. Planning and Specialized Methods
Method selection for these services begins with precise definition of the issue, rather than selecting a fixed technology for all projects.
| Objective Definition | Specifying the technical question and the expected output for the client |
| Information Review | Assessing the adequacy of documents and identifying the required data |
| Scope Definition | Specifying the equipment, area, method, and inspection limitations |
| Test Selection | Determining conventional or advanced methods appropriate to the subject |
| Inspection Execution | Performing activities in accordance with the procedure and safe conditions |
| Results Analysis | Interpreting findings in relation to the equipment condition and purpose of the examination |
| Reporting | Providing the results, limitations, and recommendations for subsequent actions |
Test methods may range from visual inspection and thickness measurement to advanced NDT methods. The use of each method depends on its technical suitability, feasibility, and the approved project scope.
### 4. Standards and Technical References
In ad hoc inspections, there is no fixed and uniform technical reference applicable to all projects. The basis for assessment is selected according to the type of equipment and the subject of the examination.
| Equipment Design and Construction Code | Understanding the initial requirements and technical basis of the equipment |
| Relevant In-Service Inspection Standard | Assessing equipment condition during the operating period |
| ASME BPVC Section V | Requirements for performing non-destructive testing |
| Relevant ISO / EN Standards | Specialized requirements for the test method or equipment |
| API 571 | Examination of damage mechanisms where relevant |
| API 579-1 / ASME FFS-1 | Fitness-for-Service assessment, where defined within the project scope |
| Manufacturer’s Instructions | Specific requirements and limitations of the equipment |
| Agreed Technical Specifications and Procedure | Defining the scope of examination and the basis for reporting |
In the absence of an explicit acceptance criterion, the basis for assessment must be determined with the client and the relevant technical authority before making a final statement.
### 5. ISQI Experience and Technical Expertise
The diversity of ISQI’s services described in the fields of equipment inspection, NDT, corrosion monitoring, and inspection of repair projects enables the development of inspection programs appropriate to various industrial issues.
In ad hoc services, the technical value lies in identifying the project’s actual requirements, selecting the appropriate combination of methods, and avoiding conclusions beyond the available evidence.
The basis for providing these services is:
Precise Problem Definition | Appropriate Method Selection | Documented Results

### 8. ISQI Approach
In specialized and ad hoc inspections, the objective is not to provide a fixed package of tests; rather, it is to design an examination process appropriate to the technical issue and the client’s decision-making needs.
ISQI’s approach is based on clearly defining the scope, purposeful use of inspection methods, documented analysis of findings, and transparent statement of limitations. If the available data are insufficient for reaching a conclusion, the need for additional testing, information, or assessment is specified in the report.
