DIN Standards Committee Materials Testing

Overview

DIN EN ISO 10140 deals with laboratory measurements of sound insulation of building elements. This part of DIN EN ISO 10140 describes test requirements for building elements and products, including detailed requirements for preparation, mounting, operating and test conditions, as well as applicable quantities and additional test information for reporting. With respect to DIN EN ISO 10140-1:2010, an annex on the testing of acoustic sealing of slits (with or without fillers) and of gaps or joints between parts of windows or doors has been incorporated. Fillers are materials to fill in joints, for example, foam or sealing tape. Gaskets (or seals) are elements to close openable joints, for example, retractable floor seals or rebate seals for doors and windows. The general guidelines in the relevant clauses of ISO 10140-2 shall always be followed. The quantity to be determined is the sound reduction index of joints, per metre of a sealed gap or joint, in decibels as a function of frequency. The test shall be carried out for the frequency range from 100 Hz to 5 000 Hz. It is intended to update DIN EN ISO 10140-1 with application rules for other products. In particular it is intended to incorporate ISO 140-18 into ISO 10140 (all parts). The test standard is directed at manufacturers of construction products as well as independent test laboratories. The committee responsible for this standard is NA 062-02-31 AA "Schalldämmung und Schallabsorption, Messung und Bewertung" ("Sound reduction and sound absorption; measurement and evaluation") at DIN.
