Overview
EN ISO 3822-1:1999 - Acoustics: Laboratory tests on noise emission from appliances and equipment used in water supply installations - Part 1: Method of measurement (ISO 3822-1:1999) - is a CEN-adopted standard that specifies a laboratory method for measuring noise generated by the flow of water through appliances and equipment. The scope covers common items such as draw-off taps, in-line valves, pressure reducers and water‑heating appliances. The standard’s method is intended to produce comparable, repeatable noise-emission results across different testing laboratories.
Key Topics
The standard addresses the essential elements required to carry out laboratory acoustic testing of water-supply appliances. Key technical topics typically covered include:
- Test scope and sample selection - which appliances and equipment types are included (taps, valves, special appliances).
- Measurement method - a defined laboratory procedure to measure noise emitted by water flow through appliances.
- Test conditions and installation - standardized mounting and hydraulic conditions to ensure comparability.
- Instrumentation and calibration - use of acoustic measurement equipment and calibration practices to ensure accurate readings.
- Data recording and reporting - how to document test parameters and present results to support comparison between laboratories.
- Comparability and repeatability - procedural controls to minimize variability and allow inter-laboratory comparison.
(Note: the above topics summarize the standard’s focus areas. For precise procedural requirements and measurement parameters refer to the official EN ISO 3822-1:1999 document.)
Applications
EN ISO 3822-1:1999 is practically useful for:
- Manufacturers of taps, valves, pressure reducers and water‑heating appliances who need to verify and certify acoustic performance.
- Independent test laboratories performing standardized noise-emission tests for product certification and R&D.
- Acoustic consultants and design engineers assessing appliance noise contribution in building services and plumbing systems.
- Regulators and procurement specialists setting noise limits or specifications for water-supply equipment.
- Water utilities and building contractors who require documented acoustic performance for product selection.
Using a standardized laboratory method helps reduce disputes, supports product labeling, and aids in product development focused on noise reduction.
Related Standards
- EN ISO 3822-1:1999 is an adoption of ISO 3822-1:1999 under CEN; national bodies may publish equivalent national standards (e.g., SIST EN ISO 3822-1).
- Users should check for later revisions, additional parts of ISO 3822, or related acoustics standards covering field tests, in situ methods, or building services noise for complete compliance and context.
