28、apability 3.2 joint chamber cut into the upper part of the joint to offer a seating for the preformed joint seals. The width of the chamber depends on the movement capability of the preformed joint seals. The bottom of the chamber supports the preformed joint seals to withstand vertical forces by tr

30、he behaviour of a preformed joint seals is mainly influenced by the elastomer. In this application mainly the following elastomers are used: EPDM rubber: Ethylen-Propylen-Dien-Monomer rubber, CR rubber: Chloroprene Rubber. EN 14188-3:2006 (E) 6 3.4 rubber hardness degree reaction forces of compresse
31、d preformed joint seals depend on geometry and rubber hardness of preformed joint seals. Hardness is measured in IRHD. IRHD is the international rubber hardness degree in accordance with ISO 48 NOTE The higher the hardness degree, the higher is the reaction force. The softer the hardness degree is,
32、the better is the ability for the lips of the rubber profile to lean tight to surface roughness of the cut joint chamber. 3.5 manufacturers limiting value MLV manufacturers stated minimum or maximum value to be met during testing according to the requirements of this European Standard 3.6 manufactur
