8 Procedure 8.1 General Carry out the procedure under normal laboratory conditions (23 ± 5) °C. If the intrinsic adhesivity of the emulsion is controlled, the procedure shall be carried out with the reference aggregate(s). The reference aggregate(s) shall be washed with water (5.2) and dried in the ventilated oven (6.10) at (110 ± 5) °C for about 2 h. […]

5 Test methods 5.1 Principle 5.1.1 A sample of the product diluted with hard water (5.2.2.7 or 5.2.2.10) is added to a test suspension of bacteria in a solution of an interfering substance. The mixture is maintained at either (20 ± 1) °C or (30 ± 1) °C for 60 min ± 10 s or (15 ± 1) h (obligatory […]

5 Preparation of test samples Take the sample in accordance with EN 58. Prepare it in accordance with EN 12594. Homogenise the sample by gentle hand stirring for at least 1 min and not more than 5 min. Pour the material into the aluminium basin placed in a sand bath (4.7) preheated to the same temperature as the sample during […]

1 Scope This European Standard specifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore. This European Standard is applicable for hose sizes from 25 mm to 250 mm, working pressures […]

1 Scope This European Standard provides a framework for specifying the characteristics and relevant test methods for polymer modified bitumens which are suitable for use in the construction and maintenance of roads, airfields and other paved areas. This framework covers the following characteristics: “consistency at intermediate service temperature”; “consistency at elevated service temperature”; “cohesion”; “durability” of consistency; “brittleness at low […]

1 Scope This European Standard specifies requirements and test methods for floor panels, which have surface layers consisting of resilient floor covering. The floor panels are considered suitable for domestic and commercial levels of use. This European Standard is not applicable to floor panels that are subject to frequent wetting, such as bathrooms, laundry rooms and saunas. This European Standard […]

1 Scope This European Standard describes a test method for determining the crack bridging ability of reinforced bitumen sheets used in waterproofing systems on concrete bridge decks and other areas of concrete trafficable by vehicles. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated […]

5.1.2 Determination and declaration The mechanical resistance (i.e. load-bearing capacity and stiffness) of the prefabricated structural member shall be determined and declared according to one of the following methods: a) Method 1: By reference to dated drawings of the structural member with information on the geometrical data and reference to the material properties of the structural components and punched metal […]

1 Scope 1.1 This European Standard establishes general principles for the execution, testing, supervision and monitoring of soil nailing. 1.2 Soil nailing is a construction technique, used to enhance/maintain the stability of a soil mass by installation of reinforcing elements (soil nails). Typical examples of soil nailing are given in Annex A. 1.3 The scope of soil nailing applications considered […]

1 Scope This European standard specifies the dimensions of the 26 mm shallow crown finish for glass bottles containing beverages. The shallow crown finish is designed to use a metal crown closure (see CE.T.I.E. data sheet EC1-02 revision 1 [2]). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the […]
