DIN 3764-2:2024-12

This document is applicable to compression seals in the form of rectangular profiles (rectangular cross-section) made of elastomer with a closed surface and for sealing or covering joints in concrete or masonry against soil moisture or non-pressing water. Typical applications for elastomer compression seals are for joints in swimming pools, sewage treatment plants, retention basins, underground joints in sewer structures and flood protection walls. This document specifies requirements for the material and installation. Application examples are given in Annex B. This document provides guidance on the selection of various base polymers of elastomer compression seals that can be used when exposed to the following: a) wastewater; b) groundwater; c) sea water; d) surface water; e) ozone loads. This document is not applicable for compression seals made of other materials. This document is not applicable for systems for the storage, filling and transshipment of substances that are hazardous for water, for slurry, liquid manure and silage seepage systems or for biogas systems. This document is not applicable for elastomeric joint profiles made of vulcanized rubber for concrete pavements, which are standardized in DIN EN 14188-3. Working Committee NA 045-02-10 AA "Fugendichtungsprofile" ("Elastomer joint sealing strips") at DIN Standards Committee Elastomer Technology (NET) is responsible for this document.
