ISO/TC 115 - Pumps

This document specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test. Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for — declaring the noise emission values, and — purpose of noise control at source at the design stage. The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market. The use of this document ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to this document are engineering methods (grade 2) and survey methods (grade 3). This document does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps. NOTE This document is specified in EN 809+A1 for noise measurements of the pump (or pump unit).

This document sets the requirements for conducting and reporting the results of a pumping system energy assessment (hereafter referenced as "assessment") that considers the entire pumping system, from energy inputs to the work performed as the result of these inputs. The objective of a pumping system energy assessment is to determine the current energy consumption of an existing system and identify ways to improve system efficiency. These requirements consist of — organizing and conducting an assessment, — analysing the data from the assessment, and — reporting and documenting assessment findings. This document is designed to be applied, to open and closed loop pumping systems typically used at industrial, institutional, commercial, and municipal facilities, when requested. This document is focused on assessing electrically-driven pumping systems, which are dominant in most facilities, but is also applicable with other types of drivers, such as steam turbines and engines. The document does not a) specify how to design a pumping system, b) give detailed qualifications and expertise required of the person using the International Standard although provides a list of body of knowledge in Annex C, c) address the training or certification of persons, d) specify how to implement the recommendations developed during the assessment, but does include requirements for an action plan, e) specify how to measure and validate the energy savings that result from implementing assessment recommendations, f) specify how to make measurements and how to calibrate test equipment used during the assessment, g) specify how to estimate the implementation cost or conduct financial analysis for recommendations developed during the assessment, h) specify specific steps required for safe operation of equipment during the assessment. The facility personnel in charge of normal operation of the equipment are responsible for ensuring that it is operated safely during the data collection phase of the assessment, i) address issues of intellectual property, security, confidentiality, and safety.

This document describes hydraulic performance tests (including cavitation tests) using a small size pump (centrifugal, mixed flow or axial pump, hereinafter referred to as a "model pump"). This document is used for pump acceptance tests with a geometrically similar model pump to guarantee the performance of a large size pump manufactured for practical use (hereinafter, a "prototype pump"). This document, however does not preclude a temporary assembly inspection or other tests on the prototype pump. Moreover, it is preferable to conduct the tests with prototype pumps unless — the capacity of the pump, namely its flow rate and/or its power input, is beyond the limitations of the test facility, though it is difficult to set a criterion for carrying out a model pump test instead of the prototype pump test in terms of the volume rate of flow or the power input, — a part of the pump is to be constructed by concrete walls and reproduction of the whole assembly is impractical, — model tests are specified by the purchaser, or — it is difficult to carry out the prototype pump test due to any other reasons. This document applies to performance tests under steady operating conditions corresponding to the prototype pump.
