21、nited Kingdom. EN 14188-3:2006 (E) 5 1 Scope This European Standard specifies requirements for preformed joint seals made of vulcanised rubber for concrete pavements. General requirements for finished joint seals are also given. This European Standard is applicable to joint seals for joints in new c
22、oncrete pavements and maintenance work in concrete highways. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced d
23、ocument (including any amendments) applies. EN 14840, Joint fillers and sealants Test methods for preformed joint seals EN ISO 9001, Quality management systems Requirements (ISO 9001:2000) ISO 48, Rubber, vulcanised or thermoplastic Determination of hardness (hardness between 10 IRHD and 100 IRHD) I
24、SO 3302-1, Rubber Tolerances for products Part 1: Dimensional tolerances 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 joint vertical discontinuity between the adjacent faces of slabs in the concrete layer of a pavement, formed for
25、 the purpose of providing some movement capability 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
26、 seals to withstand vertical forces by traffic 3.3 preformed joint seals extruded (preformed) and vulcanised elastic rubber profile that, when inserted by special machines into the joint chamber, seals the joint by compression reaction to appropriate surfaces within the joint chamber to fill the joi
27、nt and to prevent ingress of water NOTE The 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 har
28、dness degree reaction forces of compressed 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 f
29、orce. The softer the hardness degree is, 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
30、 of this European Standard 3.6 manufacturers declared value MDV value declared by the manufacturer accompanied by a declared tolerance 3.7 cold climate area area in which the temperature can go below 25 C and the opening of the joint can exceed 35 % 4 Classification Table 1 specifies five hardness c

44、 accordance with EN 14840. The compression force shall conform to the relevant values given in Table 2, line 10. NOTE As the width of joints is changing with temperature, the profile should be flexible enough to compensate for dimensional changes within a broad temperature range, sometimes down to 3
45、0 C. In this context, particular attention should be paid to the cyclic mechanical stresses and to the compression set of the material. 5.13 Dangerous substances The manufacturer shall ensure that there are no emissions of any substances hazardous to health or the environment in excess of the legall
