42、and symbols 3.1 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1.1 critical zone highly stressed area where a fracture is expected to occur in a burst test NOTE 1 It can be caused, for example, by any of the following: sudden change in
43、cross section; sharp edges; sharp radii; peak stresses; bending stresses; stresses due to other than membrane stress; changes in curvature. NOTE 2 A critical zone is analysed by any appropriate method, e.g. holographic, interferometric method, strain gauge methods, burst test, fatigue testing, FEM a
44、nalysis, etc. NOTE 3 Additionally, thermal gradients and thermal stresses due to different operating wall temperatures are to be considered in defining critical zones. 3.1.2 purchaser individual or organisation that buys pressure equipment, including assemblies or parts, for its own use or on behalf
45、 of the user and/or operator 3.1.3 manufacturer individual or organisation responsible for the design, fabrication, testing, inspection, installation of pressure equipment and assemblies where relevant NOTE 1 The manufacturer may subcontract one or more of the above mentioned tasks under its respons
46、ibility. NOTE 2 In EU member states the manufacturer is responsible for compliance with the Pressure Equipment Directive 97/23/EC. For those manufacturers outside of the EU their authorized representative inside the EU assumes this responsibility. Licensed Copy: London South Bank University, London
