1 Scope This European Standard applies to: extrusion presses from the exit side of the heater through associated handling, cooling and quenching equipment including, e.g. the puller, the hot saw, the run-out table, the stretcher, the cold saw, cold sawtable and/or coiler when incorporated into the equipment, to a point where the extruded product is passed to associated finishing equipment. […]

1 Scope This European Standard gives minimum requirements concerning material, design, construction and workmanship, procedures and tests at manufacture of refillable transportable welded cylinders made of austenitic stainless steel, justified by experimental methods, of water capacities from 0,5 l up to and including 1 50 l for compressed or liquefied gases and of a test pressure up to 90 bar. […]

8 Detailing provisions 8.1 General For general information on pre-stressed concrete tanks, reference should be made to Annex B. 8.2 Pre-stressing For the pre-stressed concrete wall, horizontal pre-stressing shall be applied. NOTE Vertical pre-stressing is not required. It can be combined with horizontal pre-stressing. The need for vertical pre-stressing depends on the tank design pressure, tank diameter, and associated permanent […]

1 Scope This European Standard is applicable to sprayed concrete, to be used for repair and upgrading of structures, for new structures and for strengthening of ground. This European Standard covers: classification related to consistence of wet mix; environmental exposure classes; young, hardened and fibre reinforced concrete; requirements for constituent materials, for concrete composition and for basic mix, for fresh […]

1 Scope 1.1 This European Standard establishes general principles for the construction of reinforced fill. 1.2 This European Standard covers engineered fills that are reinforced by the inclusion of horizontal or subhorizontal reinforcement placed between layers of fill during construction. 1.3 The scope of reinforced fill applications considered in this European Standard includes (Figure 1 ):earth retaining structures, (vertical, battered […]

4.3.2.2 Safety in the case of fire – Resistance to fire Fire resistance shall be determined and classified in accordance with EN 1 3501 -2. Note EN 357 may be used as a classification reference specific to fire resistant glazed elements. 4.3.2.3 Safety in the case of fire – Reaction to fire Reaction to fire shall be determined and classified […]

1 Scope This European Standard specifies methods for the laboratory aerodynamic testing and rating of the air flow rate measurement accuracy of fixed air flow rate measurement devices, including supply and exhaust air terminal devices (ATD) and in-duct measurement stations (IMS) and the sensitivity of such devices to flow disturbance. A general overview of different test configurations is shown in […]

1 Scope This European Standard applies to the treatment with lime of natural soils and other materials for roads, airfields and other trafficked areas and specifies the requirements for their constituents, composition and laboratory performance classification. Two types of treatment are covered, improvement and stabilization. This European Standard relates only to lime-treated layers for trafficked areas (as opposed to lime […]

1 Scope This European Standard specifies soil treated by cement for the pavement layers of roads, airfields and other trafficked areas and specifies the requirements for its constituents, composition and laboratory performance classification. It provides for the use of aggregates with grading curves, which are not constrained by the limits defined in EN 1 4227-1 for cement bound granular mixtures. […]

1 Scope This European Standard specifies requirements for preformed joint seals made of vulcanised rubber for concrete pavements. General requirements for finished joint seals are also given. This European Standard is applicable to joint seals for joints in new concrete pavements and maintenance work in concrete highways. 2 Normative references The following referenced documents are indispensable for the application of […]
