DIN 2304-1:2016-03 4 1 Scope This standard specifies requirements for the high-quality design and workmanship of structural, i.e. loadbearing, adhesive bonds, covering all steps

9、 of the adhesive bonding process chain, from design to manufacturing and maintenance. It also specifies safety classes into which the bonds covered in this standard are to be classified. A structural bond within the meaning of this standard is a material compound produced using adhesive(s) and desig

10、ned mainly to transmit mechanical loads, its loadbearing function ensuring its reliability and fitness for use throughout the life cycle of the product. As part of a technical unit the bond in this assembly contributes to the strength and stability of the unit as a whole, or of part of the unit, or

11、of a component. It is intended, in accordance with its requirement profile, to resist all stresses involved irrespective of whether these are static, dynamic or a combination of both, and whether or not environmental effects are to be considered. The main function of transmitting mechanical loads is

12、 to be ensured for any adhesive used and regardless of: the strength and deformation characteristics of the adhesive used (i.e. it covers all types of adhesive, from low modulus, highly resilient to high modulus, very stiff adhesives); the curing/hardening mechanism of the adhesive used (e.g. chemic

13、ally curing, physically hardening, combined curing mechanisms, or material covered with an adhesive, such as adhesive tape) and the sector or purpose in or for which the bonded assembly is intended to be used. This standard does not deal with bonds the manufacturing of which is otherwise covered in

14、recognized or proven technical rules, existing approvals or other standards. DIN 2304-1 establishes definitions and sets out organizational, contractual and technical principles to be followed when manufacturing adhesive bonds. 2 Normative references The following documents, in whole or in part, are

25、activators, primers, adhesives. 3.11 place of use the place where a processing step is performed 4 Selecting the bonding requirements Requirements for the high-quality workmanship of structural, i.e. loadbearing adhesive bonds shall be established by classifying them into safety classes. Within the

26、meaning of this standard, these classes relate solely to the effects of any possible failure of the bond in transmitting forces, that is, the expected consequences of mechanical failure of the bond, i.e. the main function of the bond being the transmission of mechanical loads referred to in Clause 1

27、. The safety classification of bonds in this standard does not allow for any aspects such as their suitability for use with food, their fire resistance, compliance with pollution control regulations or any stipulations regarding occupational safety or environmental protection, since these are covere

28、d in other standards, codes of practice or technical rules. The designer or the person dealing with the component concerned shall classify the bond into one of the following safety classes, taking into consideration the potential effects of bond failure: S1: high-level safety requirements; S2: mediu

29、m-level safety requirements; S3: low-level safety requirements; S4: no safety requirements. DIN 2304-1:2016-03 7 The safety class of the relevant safety requirements to be met by a bond shall be specified prior to its execution at the latest, or specified and documented by the fabricator in consulta

30、tion with the supervisor. The requirements given in Clause 5 only relate to safety classes S1, S2 and S3. A bond can be assigned a higher safety class for economic, ecological and/or functional reasons, for example. In particular applications, safety classes may already be specified in other existin

31、g standards, approvals or elsewhere. In cases of doubt, the highest possible class shall be assumed. A component may include different types of bond which can be assigned to different safety classes, depending on the requirements specified. Where a bond is not to meet at least a low-level safety req

32、uirement, this bond can be assigned to class S4. Table 1 illustrates the classification of bonds as a function of the relevant level of safety requirements. Table 1 Classification of bonds as a function of the level of safety requirements Safety class Level of safety requirement S1 High level Failur

33、e of the bond will directly or indirectly lead to an inevitable hazard to life or limb; will result in a failure of the function, the effect of which will most likely lead to an inevitable hazard to life or limb. S2 Medium level Failure of the bond can lead to a hazard to life or limb; will result i

34、n a failure of the function, the effect of which will probably involve personal injury or result in major environmental damage; will result in a failure of the function, the effect of which will most likely involve major damage to property. S3 Low level Failure of the bond will result in a failure o

35、f the function, the effect of which will probably not involve personal injury or result in major environmental damage; will result in a failure of the function, the effect of which will affect comfort or performance at the most; will result in a failure of the function, the effect of which will prob

36、ably not involve major damage to property. S4 No safety requirement Failure of the bond will result in a failure of the function, the effect of which will not, under foreseeable circumstances, involve personal injury or result in environmental damage; will result in a failure of the function, the ef

37、fect of which will only affect comfort or performance; will result in a failure of the function, the effect of which will not involve major damage to property.

43、ervisors At least one person shall be designated as bonding supervisor. DVS 3311 specifies the relevant requirements, necessary qualifications, tasks and responsibilities of a supervisor. The supervisor shall be qualified at least as a European Adhesive Bonder in accordance with DVS-EWF 3305, or hav

44、e a comparable qualification suitable for the task in question. Where a number of persons have been named supervisor, each person shall have the required qualifications. The qualifications required for bonding work shall be specified in consultation with the supervisor. The names of all persons invo

45、lved in bonding work, together with their professional qualifications and any certificates, shall be documented. DIN 2304-1:2016-03 9 For safety class S2 bonds, the following requirements shall additionally be complied with: the supervisor shall be qualified at least as a European Adhesive Specialis

46、t as in DVS-EWF 3301, or have a comparable qualification; the supervisor shall not also be charged with bonding work. In addition, for safety class S1 bonds, the following requirement shall be met: the person supervising the overall bonding process shall be qualified as a European Adhesive Engineer

The staff members entrusted with the work shall be properly instructed by the supervisor. It shall be the supervisors responsibility to justify, in

49、a transparent way, the reasons on which this permission is based. 5.2.4 Further training Supervisors shall attend further training courses offered by a third party at least every two years. The bonding personnel shall also attend such courses at least every two years. The content and duration of such training shall be specified in consultation with the supervisor. Any further training shall be documented. 5.3 Checking the con
