scope:

This standard applies to elastomer waterstops, with and without steel straps, used for sealing joints in concrete in which the waterstop is fully or partially embedded. It also applies to waterstops used as sealants against natural water as in DIN 4030-1.

DIN 7865-2 does not apply to elastomer waterstops with fabric reinforcement or waterstops made of other materials (e.g. thermoplastic elastomers (TPE), blends with thermoplastics), it also does not apply to gaskets or strip for sealing joints in plain or reinforced concrete pipes.

This standard specifies material requirements for elastomer waterstops. It does not give guidance on the practical application of the waterstops in construction work. DIN 18197 lays down specifications for the function and construction principles of waterstops, and the corresponding selection criteria.
