1 Scope 1.1 This part of EN 1 0263 is applicable to round rod, round bars and wire made of stainless steels intended for cold heading and cold extrusion having a diameter up to and including: — 25 mm for ferritic and austenitic-ferritic steels; — 50 mm for austenitic steels; — 1 00 mm for martensitic steels. 1.2 This part […]

1 Scope This standard defines the general principles to be applied to the eddy current non-destructive examination of products and materials in order to provide a defined and repeatable performance. It includes guidelines for the preparation of application documents, which describe the specific requirements for the application of the eddy current method to a product. 2 Normative references This European […]

1 Scope This European Standard specifies six methods which, experience has shown, are suitable for measuring the viscosity of a wide range of adhesives: – rotational viscometer method; – cone and plate viscometer method; – falling ball viscometer method; – glass capillary viscometer method; – flow cup method; – pressurised extrusion method. This standard does not intend to describe equipment, […]

1 Scope This European Standard specifies requirements and test methods for nozzles that introduce the extinguishing agent into a CO 2 protected zone. The design of the nozzles will influence discharge rate and thus the pressure drop in the piping network. The extinguishing agent normally arrives at the nozzle in two-phase flow form (liquid-gaseous mixture). It expands into the protected […]

1 Scope This European Standard specifies the dimensions and marking of metallic ring-joint gaskets for use in conjunction with specific flange facings (type J) of flanges complying with prEN 1759-1:2000 for Class 150,Class 300, Class 600, Class 900 and Class 1 500 for nominal sizes DN 15 to DN 600, and for Class designation 2 500 up to and including […]

1 Scope This European Standard describes test methods for preparing test portions for the determination of the binder, water content and grading of samples of bituminous mixtures, when the sample submitted to the laboratory has a mass greater than or equal to four times the test portion. 2 Normative references This European Standard incorporates by dated or undated reference, provisions […]

1 Scope This standard specifies requirements and methods for their verification for design and performances of air-assisted sprayers for bush and tree crops with respect to minimizing the risk of environmental contamination. This part applies in connection with EN 12761-1:2001 which contains general guidelines for agricultural sprayers. 2 Normative references This European Standard incorporates, by dated or undated reference, provision […]

1 Scope This European Standard provides the requirements for the tests made on welded thermoplastics semi-finished products. The selection of the appropriate test method(s) should be made in accordance with the particular type and application of welded product. The test results depend on the conditions of manufacture for the test specimen and on the test conditions. They can therefore only […]

1 Scope This standard specifies the characteristics and performance requirements of raised access floors for which the main intended use is the internal fitting out of buildings, providing full access to the services to the plenum. This standard does not cover requirements related to dangerous substances that may be subject to regulations. It is applicable to modular, factory made flooring […]

1 Scope This European Standard specifies the methods of test to be applied to evaluate the snow load resistance performances of shutters inclined less than 60° from the horizontal, those resistant either alone or in mechanical association with the glazing. It applies to – skylight roller shutters ; – conservatory roller shutters. 2 Normative references This European Standard incorporates by […]
