This part of this European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of ferritic and martensitic steels with specified elevated temperature properties. Chemical composition and mechanical properties are specified. NOTE Once this standard is published in the EU Official Journal (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 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 Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 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 Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5. General information on technical delivery condition is given in EN 10021.

This part of ISO 10893 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corresponding calibration procedures.

NOTE 1 Full peripheral testing does not necessarily mean that 100 % of the tube surface is scanned.

NOTE 2 This test can be carried out simultaneously with full peripheral ultrasonic testing for the detection of laminar imperfections (see ISO 10893-8) using the same ultrasonic transducers for both inspection requirements. Under these circumstances, the minimum lamination size under detection determines the percentage of the tube surface for scanning, according to ISO 10893-8.

This document applies for plant (containing machinery and equipment) used in the process of continuous casting of liquid steel (hereafter referred to as continuous casting machine, CCM) as defined in 3.1. This document deals with all significant hazards, hazardous situations and events relevant to machinery and equipment for the continuous casting of steel, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document specifies the safety requirements to be met during design, assembly, transport, commissioning, operation, maintenance (as described in Clause 5) and decommissioning of the equipment. This document assumes that the machinery and equipment of the plant is operated and maintained by adequately trained and competent personnel (see 7.5). Manual intervention for setting, adjustment and maintenance is accepted as part of the intended use of the plant. This document assumes that the machinery is used with adequate workstation lighting conforming to EN 12464-1. NOTE National regulations regarding lighting should be considered and could differ from requirements of EN 12464-1. This document applies to: CCM for the transformation of molten liquid steel into solid products in sections (e.g., square, rectangular, beam blank, circular) - CCM's from the point where overhead cranes or other transport systems deposit ladles to CCM (e.g., in a ladle turret, ladle car or ladle stand); - via casting process and solidification process; - via cutting equipment; - thru the run-out-area where the cut product is finished, collected and removed from that area. This document does not cover safety requirements for: - horizontal-CCM for steel; - auxiliary plants (e.g., water treatment, refractory handling); - ladles; - cranes; - winches and hoists; - conveyors or handling systems; - workshop equipment (mould and segment shop, tundish workshop). NOTE It is recommended to use this standard in case of modernization for the parts to be modernized.

This International Standard describes procedures for measuring average grain size derived from a two-dimensional polished cross-section using electron backscatter diffraction (EBSD). This requires the measurement of orientation, misorientation and pattern quality factor as a function of position in the crystalline specimen[1].

NOTE 1 While conventional methods for grain size determination using optical microscopy are well-established, EBSD methods offer a number of advantages over these techniques, including increased spatial resolution and quantitative description of the orientation of the grains.

NOTE 2 The measurements in this standard are made on two dimensional sections. The reader should note carefully the definitions used (section 3.3) which draw a distinction between the measured sectional grain sizes, and the mean grain size which can be derived from them that relates to the three dimensional grain size.

NOTE 3 The method also lends itself to the measurement of the grain size of complex materials, for example those with a significant duplex content.

NOTE 4 The reader is warned to interpret the results with care when attempting to investigate specimens with high levels of deformation.
