1 Scope This standard specifies a method for determining the long-term sealing performance of joints with thermoplastic elastomers (TPE) seals for plastics piping systems for buried non-pressure sewerage. This method, which estimates the sealing pressure for the seal, is intended to be used only for joints with sealing rings located in a socket. 2 Normative references This Standard incorporates by […]

1 Scope This standard applies to door leaves and door sets tested in acordance with prEN 1121-2 and prEN 1294. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.’ These normative references are cited at the appropriate places in the text and the publications are listed hereafer. For dated references, subsequent amendments to […]

5 Interferences There are nomally no interferences with the loss on igition determination, However, for many purposes this determination is used as an assessment of the organic part of the sludge dry mass. In this case the loss of volatile inorganic substances can occur giving high results. NOTE 1 AII sewage sludges contain iron in varping qua niies and most […]

1 Scope This European Standard specifes requirements for the tolerances on dimensions. shape and mass of hot-rolled steel channels with tapered flanges or parallel flanges. These requirements do not apply to channels produced from stainless steel. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publcations. These nomatlive references are clted at the appropriate […]

1 Scope This standard specifies requirements for classification of tubular cored electrodes used in gas shielded metal arc welding of creep-resisting and low alloy elevated temperature steels. The classification is based on the chemical composition of the all-weld metal. It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but […]

For custom designed curtain walls or special elements, the specimen shall be a size which is adequate to demonstrate its compliance with the specified requirements. All parts of the specimen shall be full size, using the same materials, details, methods o construction and fxing as intended for use in the works. Conditions for connection to the structural support shall simulate […]

1 Scope This standard speclifies a method for testing the leaktightness under vacuum of joints for thermoplastics piping systems. It is applcable to plplng systems based on thermoplastics pipes intended to be used in hot and cold water pressure applications. 2 Principle An assembly of pipes and ftings is subjected to partial vacuum for a speclic period during which the […]

1 Scope This European Standard specifies requirements for electrodeposited coatings of zinc on iron or steel with supplementary treatment. This European Standard does not specify chromate finishes which are required only for improving the adhesion of paints or varnishes. NOTE This European Standard is not intended to be used alone, but is the complement of EN 1403. It is necessary […]

1 Scope This standard gives design data in tabular form for heat and moisture transfer calculations, for thermally homogeneous materials and products commonly used in building construction. It also gives data to enable the calculation and conversion of design thermal values for various environmental conditions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other […]

1 Scope This standard specifies requirements for classification of tubular cored electrodes in the as-welded or stress relieved condition for gas shielded metal arc welding of high strength steels with a minimum specified yield strength higher than 500 N/mm². One tubular cored electrode may be tested and classified with different gases. It is recognized that the operating characteristics of tubular […]
