BS EN 15275:2015EN 15275:2015 (E) 5 Introduction Anaerobic adhesives are single component
22、adhesives that cure in absence of oxygen, curing being inhibited by the presence of oxygen and catalysed by metal ions. Polymerisation takes normally place at room temperature. Due to their curing properties these adhesives are well suited for easy assembling threaded and otherwise, pipes and tubes
23、in building and civil engineering structures. By the curing reaction a polymeric material is formed, which fills narrow gaps or micro-imperfections of threads thus sealing and bonding the joint. In addition, anaerobic adhesives may be used to joint load-bearing parts of the structures when used in t
24、ubular lap joints or pin-into-bore type joints. The primary aim of the test methods presented herein is for ranking and quality control of anaerobic adhesives and reliance should not be placed on any test results for design purposes. Design data should preferably be obtained from tests using the con
25、struction materials and configurations used in the actual design. The requirements to the assemblies are strongly depending on the intended use. Apart from the sealing ability, strength requirements may conflict with the intention to regular or occasional dismantling the joint for maintenance purpos
26、es. The values defined in this standard are considered to indicate a general or typical suitability for use of an anaerobic adhesive in a particular application in building and civil engineering structures. BS EN 15275:2015EN 15275:2015 (E) 6 1 Scope This European Standard specifies requirements and
27、 test methods for the characterisation of anaerobic adhesives intended for the general assembly of co-axial metallic elements in building and civil engineering structures including fasteners- threaded and otherwise, pipes and tubes. It is applicable to single adhesives and systems (kits) comprising
28、adhesives, activators and/or primers for both internal and external construction elements. This European Standard only applies to metallic substrates. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applic

33、f oxygen and catalysed by metal ions Note 1 to entry: Deviating from this definition, anaerobic adhesives may be defined also as anaerobic polymerisable compounds, or anaerobic jointing compounds including liquid, gel like or pasty sealants. 4 Performance characteristics for intended uses The manufa
34、cturer shall undertake initial performance tests on the product in accordance with Table 1 and corresponding to the type of the defined application e.g. retaining co-axial assemblies (see 5.1), threaded fasteners (see 5.2) and threaded joints in contact with 1st, 2nd and 3rd family gases and hot wat

36、ed for use for retaining metallic co-axial cylindrical joints such as load bearing tubular or pin-and-collar-type cylindrical assemblies. The test method can be also used to determine the shear strength of threaded fasteners. However, in this case it is recommended to assess the bond ability of the
37、threaded assembly by means of the torque strength according to EN 15865. 2 Breakloose torque 5.2.1 Nm EN 15865 Only for products intended for use for securing or locking metallic threaded assemblies. The fastener specimen should be preloaded at 5 Nm, otherwise the input torque has to be explicitly m

45、5.4 g/m3EN 13999-1 and EN 13999-2 aThe determination of the strength and torque strength under the additional environmental conditions is only partly needed for specific applications by demand of the user or operator. To assess the heat resistance of an anaerobic adhesive measurement of the static s
46、hear strength in accordance with EN 15865 or torque strength in accordance with EN 15337 may be conducted at other specified environmental conditions. Indicative performance requirements are given in Annex A depending on the intended use. These values are drawn from laboratory and practical experien
47、ce and can be considered to indicate satisfactory performance under normal practical use and conditions. The torque strength of anaerobic adhesives on threaded fasteners is expressed as breakloose torque measured on assemblies preloaded with an input torque of 5 Nm. Also, identical input torque is a
48、ssumed to be applied to the specimens when measuring the prevailing torque. Attention shall be drawn to the fact, that shear strength properties measured in accordance with EN 15337 and EN 15865 are valid for low-carbon respectively zinc-phosphated steel substrate materials. In general, curing of an
49、aerobic adhesives may be significantly affected by the nature of the used adherends, thus testing using the specific materials of the intended application is recommended. It is also recommended to evaluate heat resistance or durability of the intended joint under conditions reflecting the environmental loading expected to encounter in practice. 5 Test methods The test methods could be divided according to the type of the application, and the properties relevant to meet the requirements by the joint as follows: 5.1 Retaining co-axial assemblies
