Full title and description

St ISO 3977-1-1997 — "Gas turbines — Procurement — Part 1: General introduction and definitions" (ISO 3977-1:1997). This part provides the general introduction to the ISO 3977 series and defines terms and concepts used throughout the procurement and specification guidance for gas turbine systems.

Abstract

This document is the first part of the ISO 3977 series addressing procurement of gas turbines. It gives the general introduction to the series, establishes scope and purpose of the procurement parts, and lists/defines key terms used in subsequent parts of ISO 3977 (cross-referencing related terminology standards such as ISO 11086 where appropriate). The edition was published in 1997 and the text of this edition was last confirmed as current by ISO in 2023.

Scope

ISO 3977-1:1997 sets out the introductory material and definitions used for the ISO 3977 series on gas turbine procurement. It establishes the terminology to be used in procurement specifications, clarifies the relationship between parts of the series, and provides a baseline for interpreting ratings, reference conditions and procurement requirements addressed in other parts of ISO 3977. The part is intended to ensure consistent interpretation of terms across the procurement lifecycle.

Key topics and requirements

• Definitions and standardized terminology for gas turbine procurement (foundation for other parts of ISO 3977).
• Introductory guidance on structure of the ISO 3977 series and its use in procurement documents.
• Cross-references to related standards and reference-condition conventions used elsewhere in the series.
• Clarification of the relationship between procurement, ratings, design requirements and testing sections contained in later parts.

Typical use and users

Used by procurement engineers, specifications writers, original equipment manufacturers (OEMs), plant owners/operators, technical consultants and contract/legal teams involved in gas turbine purchase contracts and technical specifications. It is used as the authoritative source for consistent terminology when preparing or reviewing procurement documents and when aligning supplier proposals to purchaser requirements.

Related standards

ISO 3977-1 is the introductory part of the broader ISO 3977 series. Related parts include ISO 3977-2 (reference conditions and ratings), ISO 3977-3 (design requirements), ISO 3977-4 (fuels and environment), ISO 3977-5 (applications for petroleum and natural gas industries), ISO 3977-7 (technical information), ISO 3977-8 (inspection, testing, installation and commissioning) and ISO 3977-9 (reliability, availability, maintainability and safety). The ISO 3977 family draws on and aligns with other industry standards (for example ASME and API) where appropriate.

FAQ

Q: What is this standard?

A: ISO 3977-1:1997 is Part 1 (General introduction and definitions) of the ISO 3977 series dealing with procurement of gas turbines; it defines terminology and sets out the structure and intent of the procurement guidance.

Q: What does it cover?

A: It covers introductory material and standardized definitions used across the ISO 3977 procurement series; it does not specify technical ratings or testing procedures itself but provides the terms and context used by those parts.

Q: Who typically uses it?

A: Procurement teams, OEMs, plant operators, consultants and standards authors use it to ensure consistent terminology and interpretation when preparing or evaluating gas turbine procurement specifications.

Q: Is it current or superseded?

A: The 1997 edition (ISO 3977-1:1997) remains published and was confirmed by ISO in the 2023 systematic review, so this edition is current (confirmed). Users should still check ISO's catalog for any changes before placing contractual reliance.

Q: Is it part of a series?

A: Yes — ISO 3977 is a multipart standard covering procurement, ratings, design, fuels/environment, applications and testing/inspection. ISO 3977-1 is the introductory part of that series.

Q: What are the key keywords?

A: Gas turbines, procurement, definitions, ratings, reference conditions, specifications, ISO 3977.
