What is BS EN 15274 - Requirements of general-purpose adhesives about?
BS EN 15274 discusses general-purpose adhesives for structural assembly. General purpose adhesives offer a reliable hold and bonds to a variety of substrates. BS EN 15274 specifies requirements for adhesives intended for use in the creation and general assembly of load-bearing, structural elements used in civil engineering works and the construction of buildings.
Other than the exceptions stated, it embraces all combinations of bonded materials, used to create, or repair load-bearing elements. BS EN 15274 covers individual adhesives and special purpose kits comprising various combinations of adhesive types and components. BS EN 15274 includes test methods and methods of assessment.
Note: The performance requirements in BS EN 15274 may not be applicable to highly specialized applications in extreme environmental conditions, e.g., cryogenic use, nor do they cover specialized circumstances such as accidental impact, e.g., due to traffic or ice, or earthquake loading where specific performance requirements will apply.
Note 2: BS EN 15274 does not cover:
- Prefabricated, bonded structural components
- Concrete bonded either to itself or steel or a material based on carbon fibre
- Wood, when bonded to itself to form a timber-based, a laminated beam [of the type known as a ‘Glulam’ beam] intended for use as a major structural, load-bearing element
- Thermoplastics [e.g., polyethene, polypropylene, polyamide and fluorinated polymers in general] unless they have been specifically prepared [usually through a specialized oxidative process] for bonded assembly on site
- Co-axial metallic assemblies comprising fasteners- threaded and otherwise, pipes and tubes
- Glass assemblies in structural glazing applications made using silicone adhesives
- Those structural elements that are permanently immersed in water
Who is BS EN 15274 - Requirements of general-purpose adhesives for?
BS EN 15274 on requirements of general-purpose adhesives is useful for:
- Adhesive manufacturers
- Construction equipment manufacturers
- Civil engineers
- Design engineers
- Quality control personnel
Why should you use BS EN 15274 - Requirements of general-purpose adhesives?
Adhesive, also known as glue, cement, mucilage, or paste, is any non-metallic substance applied to one or both surfaces of two separate items that binds them together and resists their separation. BS EN 15274 states the intended use of an adhesive is for internal and external construction elements and those cladding and covering elements (excluding ceramic tiles) specifically required, by regulatory authorities, to provide protection from fire in identified building zones, including escape routes. The compliance of general-purpose adhesives with the requirements of BS EN 15274 and with the performances declared by the manufacturer in the DoP is demonstrated by the determination of the product type and factory production control by the manufacturer, including product assessment.
All performances related to characteristics included in BS EN 15274 are determined when the manufacturer intends to declare the respective performances unless the standard gives provisions for declaring them without performing tests. (e.g., use of previously existing data, CWFT and conventionally accepted performance). Assessments previously performed in accordance with the provisions of BS EN 15274 may be considered provided that they were made to the same or a more rigorous test method, under the same AVCP system on the same product or products of similar design, construction, and functionality, such that the results are applicable to the product in question. For the purposes of assessment, the manufacturer's products may be grouped into families, where it is considered that the results for one or more characteristics from any one product within the family are representative of that same characteristic for all products within that same family. Using BS EN 15274 you can specify requirements for adhesives intended for use in the creation and general assembly of load-bearing, structural elements used in civil engineering works and the construction of buildings.
