1 European Standards In early 2000, the European Union created and adopted a new classification system for adhesives and grouts. According to European Standards, classes EN and were created for adhesives and EN for joint fillers, facilitating the easy identification and classification of products depending on their scope of application and their technical specifications. The classification of products is now based on performance and application characteristics and is referred to as symbols of compliance on the packaging and the brochures of the classified products. All of the above apply to more categories of products such as: rendering and plastering mortars (ΕΝ 998-1) masonry mortars (ΕΝ 998-2) screed materials and floor screeds (ΕΝ ) admixtures for concrete, mortar, grout (ΕΝ 934-2) products and systems for the protection and repair of concrete structures (ΕΝ 1504) poducts for drywall joints (ΕΝ 13963) The CE marking is a certified guarantee for all types of products, with regards to the minimum characteristics required by the applicable standards. These characteristics remain unaltered for all relevant quantities. The verification and compliance procedures for each product are defined in detail in the European technical specifications. All products are tested and comply with the appropriate European standards and regulations. Those products that do not bear the CE marking, are not required to comply with the European standards. Ιτ must be mentioned that for all DUROSTICK products not bearing the CE marking, the company certifications (ISO 9001 since 2000), the well organized and exceptionally equipped Chemical Laboratory as well as the Properties Testing Laboratory, both located in the premises of DUROSTICK, as well as the highly skilled scientific staff and the high tech, modern facilities together with and brand new mechanical equipment, are the strongest guarantee for the quality and reliability of its products.

Durostick has studied, designed and certified per the European standard ETAG 004, the Integrated System for External Insulation of buildings (External Thermal Insulation Composite System (ETICS)) with the name THERMOSEAL ; certification number EOTA: ETA-13/0006 and EOTA: ETA-13/0007. The system is registered Class 1 in measurements made in the laboratories of the Notified body BVFS in Austria and was certified by the Notified Organization OIB. The tile and special building component adhesives are tested under the European Standard EN and EN in the Open time Slip Tensile adhesion after: EN days in normal environment conditions - Heat ageing at +70 C - Immersion in water - 25 freeze-thaw cycles Transverse deformation after 3 point bending load Renders and plasters are tested under the European Standard EN in Compressive EN after 28 days of curing Capillary water absorption Masonry mortars are tested under the European Standard EN in Compressive after ageing of 28 days EN Capllary water absorption Chloride ion content 8
