Noise of water taps and supply valves
Acoustics
Precisely determining the noise level (Lap) from taps and fittings in accordance with DIN EN ISO 3822
In our specialized testing facility, we can determine the noise level Lap in accordance with DIN EN ISO 3822. The noise generated by sanitary taps, fittings, valves and other water installation devices is recorded in detail, transmitted via a standardized measuring setup in our measuring lab and then compared with the noise level generated by the installation noise standard (IGN).
As an accredited testing laboratory, we offer a comprehensive range of services for testing the acoustic properties of your water installation systems, including drinking water filters and water softeners. In addition to detailed test reports, our experts also prepare Technical Approvals (TA) containing official test numbers (e.g. PA-IX 1234/IA or P-IX 56789/II).
Put your trust in the long-standing expertise of our specialists to reliably document the acoustic performance of your products and devices. We would be happy to assist you with the test you require. Please contact us directly. We look forward to hearing from you.
