9、15-02 3 Foreword This standard has been prepared by Working Committee NA 045-02-10 AA Fugendichtungen of DIN-Normenausschuss Kautschuktechnik (FAKAU) (DIN Standards Committee Rubber Technology). It lays down material requirements for elastomer waterstops (joint sealing strips) and also specifies the

10、 scope and frequency of inspections. Users of this standard may reproduce the forms in Annexes A to E without prejudice to the rights of DIN regarding the rest of the document. DIN 7865 consists of the following parts under the general title Elastomer waterstops for sealing joints in concrete: Part

11、1: Shapes and dimensions Part 2: Material specifications and testing Part 3: Range of applications Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN and/or DKE shall not be held responsible for identifying any or all such patent

12、 rights. Amendments This standard differs from DIN 7865-2:2008-02 as follows: a) the standard has been editorially revised. b) the former Annex B (informative) “Proof of qualification” has been deleted; c) a new Annex B (informative) “Test report” has been added; d) Annex C (informative) “Declaratio

13、n of compliance with the order” has been added; e) Annex D (informative) “Inspection certificate A” has been added; f) Annex E (informative) “Inspection certificate B” has been added; g) Annex F (informative) “Third-party inspection” has been added.

14、 7865-2:2015-02 4 1 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 no

15、t 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 req

16、uirements 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. 2 Normative references The follo

17、wing documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

25、s of this document, the terms and definitions in DIN 7865-1 and the following apply. 3.1 factory production control continual control of production exercised by the manufacturer SOURCE: DIN 18200:2000-05, 2.2, modified 4 Bonds and jointing techniques 4.1 General In areas near joints and bonds used t

26、o form shaped elements, the width of elastomer waterstops may be changed by no more than 100 mm, and in the case of waterstops with steel straps by no more than 150 mm, measured at a right-angle to the bond. The cross-section of the waterstop shall not be weakened. Any centre bulbs, anchors or ancho

27、r ribs shall be continuous along the entire waterstop. Elastomer waterstops shall be bonded by means of vulcanization, i.e. through the addition of raw material and through the effects of heat and pressure. When forming joints on-site a heated press shall be used that is suitable for the waterstop s

28、hape. All equipment used, the materials needed for jointing, and the vulcanization parameters (time and temperature) shall comply with the information supplied by the waterstop manufacturer. Bonds formed without pressure and heat with the help of external materials (e.g. adhesives) are not permitted

29、. Bonds formed by means of vulcanization may only be loaded after they have cooled down. Joints formed on-site shall only be formed by specialists provided by the waterstop manufacturer or by a joint technician trained by the manufacturer and named by the construction company according to the manufa

30、cturers guidelines. Skilled construction workers (“Baufacharbeiter”) or construction specialists (“Baufachwerker”) who, because of their experience in construction practice over many years perform skilled tasks, are approved to train construction personnel or waterstop specialists. This training inc

31、ludes the theory and practice of jointing using elastomer waterstops, and imparts the necessary relevant technical information for applications involving waterstops and related sealants. DIN 7865-2:2015-02 6 4.2 Elastomer waterstops with steel straps Steel straps shall be continuous, and permanently

32、 and tightly bonded. When bonding FMS- and FS-profile waterstops, special care shall be taken to ensure that there are no weak spots in the rubber-to-metal bond (bond area between the elastomer and the steel strap) (e.g. by covering this area during vulcanization), especially in the case of joints f

33、ormed on-site. 4.3 Elastomer cap seals Bonds shall be homogenous, tight and permanent. Proof of bond strength is not necessary. 5 Requirements 5.1 Properties When tested in accordance with Clause 5 the material properties of the elastomer waterstops and their bonds shall meet the requirements given

34、in Table 1. These requirements apply for each single result obtained throughout the test series. Required values specified in Table 2*)column 2 shall be rounded in accordance with DIN 1333:1992-02, 4.5.1. EXAMPLE Requirement for tear strength 10 MPa, single value obtained in test series: 9,9 MPa, ro

35、unded to the nearest half: 0,5 MPa, sum 10,4 MPa, rounded single value: 10 MPa. *)Translators note. Table 1 is meant here.
