DIN EN ISO 17769-2 2012-11 PDF

Full title and description

DIN EN ISO 17769-2:2012-11 — Liquid pumps and installation — General terms, definitions, quantities, letter symbols and units — Part 2: Pumping system. This document is the German (DIN/EN) adoption of ISO 17769‑2:2012 and defines the standardized terms, letter symbols and units used when describing the flow of liquids through rotodynamic and positive‑displacement pumps and their associated pumping systems.

Abstract

Specifies terms, letter symbols and units related to the flow of liquids through rotodynamic and positive displacement liquid pumps and associated installations, with emphasis on pumping systems. The standard clarifies communications between installation designer, manufacturer, operator and plant constructor, and aligns symbols and definitions with ISO 80000‑1 where appropriate.

Scope

This part of ISO 17769 applies to conditions described by positive values of volumetric flow and pump head and deals primarily with pumping systems rather than component‑level definitions. It defines the terms, quantities, letter symbols and units commonly used to describe liquid pumping installations (both rotodynamic and positive‑displacement). Where possible the symbols and definitions are made consistent with ISO 80000‑1; some deviations are included for clarity in the pump domain.

Key topics and requirements

• Standardized terminology for liquid pumps and pumping systems (definitions of commonly used terms).
• Specification of letter symbols (formula symbols) used to denote flow, head, power, efficiency and related quantities.
• Recommended units and unit notation for quantities relevant to pump performance and system descriptions.
• Alignment and cross‑reference to ISO 80000‑1 (quantities and units) to promote consistency of symbols and units across standards.
• Application limited to positive values of flow and pump head; component‑level or accessory‑specific symbols may be excluded or treated separately.

Typical use and users

Used by pump designers, system and plant engineers, manufacturers, commissioning and maintenance teams, technical authors and standards committees. The standard helps ensure unambiguous specification, documentation and communication of pump and system performance data in procurement documents, technical reports, calculation sheets and control/monitoring systems.

Related standards

Key related documents include ISO 17769‑1:2012 (Part 1 — Liquid pumps) which complements Part 2 by addressing pump‑specific terms and quantities, and ISO 80000‑1 (Quantities and units — Part 1: General) which provides the general rules for quantities, units and symbols that ISO 17769 references and aligns with. Additional national EN/ISO adoptions (e.g., BS EN ISO, UNE‑EN ISO, ÖNORM) exist for respective markets.

FAQ

Q: What is this standard?

A: DIN EN ISO 17769‑2:2012‑11 is the German/European adoption of ISO 17769‑2:2012, the international standard that defines terms, letter symbols and units for pumping systems used with liquid pumps.

Q: What does it cover?

A: It covers standardized terms, quantities, formula (letter) symbols and units specifically for pumping systems (flow, head, power, efficiencies and related quantities), intended to harmonize communication between designers, manufacturers and operators. It focuses on conditions with positive flow and pump head and aligns symbols with ISO 80000‑1 where applicable.

Q: Who typically uses it?

A: Pump manufacturers, system designers, plant engineers, test and commissioning teams, standards writers and technical documentation authors use this standard to ensure consistent notation and units in specifications, datasheets and reports.

Q: Is it current or superseded?

A: The ISO 17769‑2:2012 edition is the published Part 2 edition from 2012; national EN/DIN adoptions were published in late 2012. As of the latest bibliographic listings the 2012 edition remains the published Part 2 text; users should check national catalogues or ISO for any later amendments or confirmations before relying on it for regulatory or contractual requirements.

Q: Is it part of a series?

A: Yes — ISO 17769 is a multipart series. Part 1 (ISO 17769‑1:2012) addresses liquid‑pump specific terms; Part 2 addresses pumping systems. The series replaces earlier combined editions and aligns with general quantities/units standards such as ISO 80000‑1.

Q: What are the key keywords?

A: Pumps, pumping system, liquid pumps, rotodynamic, positive‑displacement, terms and definitions, letter symbols, units, quantities, ISO 17769.
