Overview

ISO 3822-2:1995 is Part 2 of the ISO 3822 series on laboratory tests for noise emission from water-supply appliances. This part defines the mounting and operating conditions to be used when measuring noise emitted by draw-off taps and mixing valves (including single- and two-supply sanitary fittings) so that acoustic results are repeatable and comparable. The document replaces the first edition and complements the measurement method given in ISO 3822-1.

Key practical points drawn from the standard include required test pressures, inlet and outlet arrangements, and treatment of interchangeable accessories to ensure low-noise, standardized hydraulic conditions during laboratory measurement.

Key Topics

Scope and applicability: Applies to draw-off taps, mixers and conventional mixing valves used in building water installations. Excludes certain combined electrical or special devices.

Test pressure range: Mounting and operating conditions are intended for a dynamic pressure interval of 0.1 MPa to 0.5 MPa; routine tests are specified at 0.3 MPa and 0.5 MPa unless flow regulators require different settings.

Water temperature: For mixers supplied with hot and cold water, tests are performed with water at ambient temperature not exceeding 25 °C at each supply.

Inlet connections and mounting:

Threaded fittings: connect to the test circuit using specified long-radius bends or nipples in accordance with ISO 49 and ISO 7-1.
Smooth inlets: install with rigid, leak-tight connections that avoid trapped air (welded spigots, union nuts, or compression fittings).

Interchangeable outlets: Accessories such as aerators, shower hoses or handsets are replaced by standardized low-noise hydraulic resistances (per the referenced annexes) when they are removable; if fixed they remain in place during testing.

Test procedure summary: Typical steps include opening fully, stabilising dynamic pressure, measuring flow and acoustic levels, and recording maximum acoustic levels during controlled closure or temperature control variations for mixers.

Applications

Product development and acoustic performance verification for water fittings (taps, mixers, valves).

Quality control and type testing for manufacturers to ensure consistent noise emission behaviour across production runs.

Comparative laboratory evaluation for specifiers, consultants and regulatory bodies assessing acoustic suitability of sanitary fittings in buildings.

ISO 3822-4: Guidance on mounting arrangements and low-noise hydraulic resistances for interchangeable outlets.

ISO 7-1 and ISO 49: Thread and fitting dimensions and recommended connection practices used in test rig assembly.

By following ISO 3822-2:1995 mounting and operating requirements, laboratories and manufacturers achieve reproducible noise emission data for draw-off taps and mixing valves, supporting product improvement and acoustic specification compliance.
