Overview
IEC TR 61366-7:1998, published by the International Electrotechnical Commission (IEC), delivers essential guidelines for preparing technical specifications for storage pumps within hydraulic power projects. As part 7 of the IEC 61366 series, this technical report aids employers, consultants, and manufacturers in drafting precise tendering documents, evaluating offers, and defining requirements for procurement and commissioning of storage pump equipment. Its scope encompasses all critical aspects of technical documentation, from design and performance guarantees to installation and commissioning, ensuring alignment with international best practices for storage pump tenders.
Key Topics
IEC TR 61366-7 covers the following major areas relevant to storage pumps in hydropower and pumped-storage facilities:
Applications
IEC TR 61366-7:1998 is applicable to:
- Hydropower Project Owners and Developers: Supports detailed tender preparation for storage pump procurement, ensuring clarity and completeness in technical requirements.
- EPC Contractors and Manufacturers: Provides a consistent framework for submitting bids that address all required technical, mechanical, and operational criteria.
- Consulting Engineers: Serves as a reference when evaluating storage pump tenders, comparing offers, and reviewing compliance with project and international standards.
- Operation & Maintenance Teams: Serves as a basis for developing operation manuals, training programs, and maintenance planning for installed storage pump equipment.
By adhering to IEC TR 61366-7, stakeholders ensure that all technical details of storage pumps-including workmanship, quality assurance, testing, and documentation-are covered, reducing risks during procurement and operation phases.
Related Standards
For comprehensive storage pump and hydraulic machinery tendering documents, consider the following related international standards:
- IEC 60041: Field acceptance tests for hydraulic turbines, storage pumps, and pump-turbines
- IEC 60193: Model acceptance tests for hydraulic turbines
- IEC 60609: Cavitation pitting evaluation in hydraulic turbines, storage pumps, and pump-turbines
- IEC 60805: Guidelines for commissioning, operation, and maintenance of storage pumps and pump-turbines
- IEC 60994: Field measurement of vibrations and pulsations in hydraulic machines
- ISO 3740: Acoustics - Determination of sound power levels of noise sources
Additionally, the other parts of IEC 61366 address technical specifications for different hydraulic machine types (e.g., Francis, Pelton, Kaplan turbines, pump-turbines), offering a harmonized approach for full hydro project documentation.
