39、014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to 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 t
40、o verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 102221 to EN 10222g9395 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Direct
41、ive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
