This document contains requirements and test methods for fabric reinforced material for diaphragms used in gas distribution plants and appliances operated by pressures up to 45 bar and in temperatur range of -10 to +60 °C.
This Technical Report (TR), taking into account the state of the art in the Member States, identifies the role of testing in the assessment of construction products in view of possible emissions and makes recommendations on the testing procedures. The TR reviews in accordance with the experience already gained, the basis for deciding whether or not the use of horizontal test method standards for construction products is practicable and/or necessary in the sense of article 7.2 of the Construction Products Directive, and the Guidance Papers, in particular Guidance Papers H and M. The Technical Report also recommends how harmonized technical specifications (e. g. harmonized product standards) should address the subject of regulated dangerous substances. The TR also recommends how the expertise of product Technical Committees and EOTA Working Groups can be used when drafting the horizontal test method standards. The TR provides recommendations for complete testing procedures in the overall framework according to the methods for the Attestation of Conformity.
This Technical Report (TR) provides step-by-step guidance for product Technical Committees (TCs) and EOTA Working Groups (WGs), on how the harmonized measurement/test methods can be integrated into technical specifications.
This standard gives requirements and recommendations for the design, analysis, materials, fabrication testing and operation of subsea completion/workover (C/WO) riser systems run from a floating vessel.#,,#
This ISO standard specifies minimum thickness requirements for six classes of zinc coating applied to ferrous products by the sherardizing process for the purpose of protection against corrosion and wear. It also specifies the minimum requirements of the zinc dust to be used in the sherardizing process. This standard does not specifiy any requirements for the surface condition (finish or roughness) of the basis material before sherardizing.After-treatments or organic over-coatings of sherardized articles are not in the scope of this standard. This standard does not apply to sherardized products (e. g. fasteners, tubes) for which specific standards exist and which may include additional requirements or requirements which are different from those of this standard.NOTE Individual product standards can incorporate this standard for the coating by quoting its number, or may incorporate it with modification specific to the product.
This standard specifies definitions, nominal sizes, principles of design, performance requirements, marking, testing and quality control for separator systems for light liquids.\nThis standard applies to separator systems for light liquids, where light liquids are separated from waste water by means of gravity and/or coalescence.\nThis standard does not apply to the treatment of stable emulsions, solutions of light liquids and water, grease and oils of vegetable and animal origin.
