Описание (английский):

Forms the first of a set dealing with tests of pumps and specifies precision class tests (former class A). Engineering class I and class II tests (former classes B and C) will be the subject of a further standard. Defines the terms and quantities that are used and specifies general requirements for tests. Does not specify constructional tolerances.

Overview

ISO 5198:1987 - "Centrifugal, mixed flow and axial pumps - Code for hydraulic performance tests - Precision grade" is an International Standard that establishes procedures and definitions for precision-class (former class A) hydraulic performance testing of pumps. It is the first in a set of pump-testing standards and is intended for laboratory-level, high-accuracy measurements used primarily in research, development and scientific investigations. The standard defines terms and quantities, specifies general test requirements and details measurement methods without prescribing constructional tolerances.

Key topics

Scope and purpose

Precision-class testing for centrifugal, mixed-flow and axial pumps.
Applies to pumps tested on bench or site (where installation permits).
Does not define constructional tolerances or contractual acceptance limits.

Definitions and statistical concepts

Formal definitions for measuring systems, instruments, steady/unsteady processes, mean/variance, fluctuations, response time and readings.
Emphasis on steady operating conditions and appropriate integration periods.

Measurement methods (section summaries)

Flow measurement - recommended methods and references to established flow-measurement techniques.
Head and speed - procedures for accurate head and rotational-speed measurement.
Power input and efficiency - methods for power measurement and for efficiency determination using the thermodynamic method.
Cavitation tests - procedures for cavitation characterization and special cavitation test annexes.

Uncertainty and data handling

Annexes cover estimation and analysis of uncertainties, comparison of test results with specified duties, and thermodynamic properties of water relevant to efficiency measurement.

Applications

Who uses ISO 5198:1987 and why:

R&D engineers and test laboratories - to produce repeatable, high-precision pump performance curves for model development and validation.

Manufacturers and designers - for benchmarking pump designs and verifying performance in controlled conditions.

Standards and metrology specialists - to define measurement protocols, compute uncertainties and report results consistently.

Buyers and specifiers - as a reference when contracting precision tests (with contractual acceptance criteria agreed separately).

Practical uses include high-accuracy performance verification, cavitation assessment, efficiency mapping using thermodynamic methods, and laboratory comparison of pump prototypes.

Related standards

Relevant documents and cross-references cited in ISO 5198:1987:

ISO 2548, ISO 3555 (other pump test codes / acceptance classes)

ISO 5167, ISO 5168 (flow measurement and uncertainty)

ISO 3534 (statistics - vocabulary and symbols)

IEC publications for storage-pump acceptance testing (e.g., IEC 198, IEC 497)

Other ISO methods for flow measurement and tracer techniques

ISO 5198:1987 is essential when extremely precise hydraulic performance data are required; contractual interpretation of results (acceptance limits) must be agreed separately between parties.
