28、ed cold drawn tubes of circular cross section for use in hydraulic and pneumatic power systems. Tubes according to this part of EN 10305 are characterized by having precisely defined tolerances on dimensions and a specified surface roughness. The allowed pressure rates and upper temperatures are the

29、 responsibility of the customer in accordance with the state of the art and in application of the safety coefficients specified in the applicable regulations, codes or standards. Concerning the lower temperature range applicability the impact energy requirements are given at 0 C. NOTE Once this stan

30、dard is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to

31、 a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done. 2 Normative references Th
