Overview

EN ISO 3822-2:1995 is a CEN-adopted acoustics standard that defines the mounting and operating conditions to be used in laboratory tests of noise emission from draw-off taps and mixing valves in water supply installations. Part 2 of the ISO 3822 series focuses specifically on how these fixtures should be installed and operated during controlled acoustic measurements so results are reproducible and comparable between test laboratories. This edition replaces the first technically revised edition.

Key topics

• Scope and purpose: clarifies that the standard applies to laboratory measurement of noise generated by water flow through taps and mixing valves used in building water supply systems.
• Mounting conditions: requirements for how taps and mixing valves are to be fixed to test rigs or panels to simulate realistic installation while minimizing extraneous structure-borne noise.
• Operating conditions: guidance on the flow and pressure conditions, valve positions, and operating modes to be used during acoustic tests to ensure consistent and repeatable measurements.
• Test environment and reproducibility: considerations for laboratory set-up to reduce background noise and variability, enabling meaningful comparison across tests.
• Measurement protocol and reporting: expectations for documenting test set-up, operating parameters, and measured noise emissions so results are traceable and useful for product assessment.

(Note: the standard text provides detailed procedural requirements; this summary avoids inventing specific numerical test values or thresholds.)

Applications

EN ISO 3822-2:1995 is practical for:

• Manufacturers of draw-off taps and mixing valves seeking to evaluate and reduce hydraulic noise during product development.
• Independent test laboratories performing standardized noise emission tests for compliance, product data sheets, or comparative studies.
• Acoustic and plumbing engineers assessing fixture selection and installation impacts on sanitary system noise in buildings.
• Product certification bodies and specifiers who require standardized noise data for procurement and compliance decisions.

Using this standard helps stakeholders produce reliable, repeatable acoustic data that can inform quieter product designs and better installation practices in residential, commercial, and institutional water supply systems.

Related standards

• Other parts of the ISO 3822 series and national/adopted versions (EN ISO) cover laboratory noise tests for additional appliances and equipment used in water supply installations.
• Complementary standards on acoustic measurement, plumbing system testing, and product noise declaration may be referenced when establishing a complete test program.
