Pumps - Rotodynamic pumps - Glandless circulators having a rated power input not exceeding 200 W for heating installations and domestic hot water installations - Noise test code (vibro-acoustics) for measuring structure- and fluid-borne noise

This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P1 ≤ 200W, intended to be used in heating installations, domestic hot water service installations and cooling systems, and is limited to glandless circulators with threaded connections of 11/2 inch. The test code comprises the test rig, the measurement method and the test conditions.
This European Standard applies to glandless circulators, which are manufactured after the date of issue of this European Standard.
The characterization principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a glandless circulator.

Overview

EN 16644:2014 is a CEN noise test code for the vibro-acoustic characterization of small glandless circulators (rotodynamic pumps) with a rated input P1 ≤ 200 W. It covers devices intended for heating installations, domestic hot water and cooling systems and is limited to glandless circulators with threaded connections of 1½ inch. The standard defines the required test rig, measurement methods and test conditions to quantify both fluid-borne and structure-borne noise transmitted into connected piping.

Key Topics and Requirements

• Scope and applicability
  • Applies to glandless circulators manufactured after the standard’s issue date.
  • Focused on residential and light-commercial circulators where low noise is critical.
• Test rig specifications
  • Detailed components: test object (pump), vibration and pressure measurement pipes, liquid and solid anechoic terminations, tank/pressure vessel, flow meter, regulation valve, pipe supports and frame.
  • Assembly, foundation and instrumentation requirements to ensure repeatable and reproducible results.
• Measurement methods
  • Fluid-borne noise: measured as pressure fluctuations in the straight pipe; expressed as fluid-borne intensity (W/m²) and fluid-borne power (W).
  • Structure-borne noise: measured via vibration on the pipe wall using accelerometers; expressed as structure-borne intensity (W/m) and structure-borne power (W).
  • Determination of power levels (LWfb, LWsb), energy propagation coefficients and sense of power propagation.
• Instrumentation & calibration
  • Use of pressure transducers and accelerometers with defined calibration procedures.
  • Requirements for measurement parameters, frequency range, signal processing and data acquisition.
• Measurement influences
  • Guidance on electromagnetic interference, earth loops, vibration surroundings and initial operation time.
• Reporting
  • Standardized list of information to be reported for test results to allow comparison and certification.

Applications and Who Uses It

• Pump manufacturers - design validation, product development and noise performance verification.
• Independent test laboratories - accredited testing to provide comparable noise data for product declarations.
• HVAC and building services engineers - selection of low-noise circulators for residential heating, DHW and cooling systems.
• Acoustical consultants and certification bodies - assessing compliance with local/regional noise requirements and advising on mitigation.
• Practical benefits include consistent noise data for tendering, improved occupant comfort, and clearer conformity assessment for market entry.

Related Standards

• EN 16297-1:2012 - general requirements and testing for glandless circulators (energy efficiency and EEI).
• Supersedes EN 1151-2:2006 (replaced by EN 16644).
• Other referenced standards include EN 50160 and ISO 2016 for relevant electrical and assembly conditions.
