Magnesium and magnesium alloys - Magnesium alloys for cast anodes
This European Standard specifies the grades and the corresponding requirements for magnesium alloys for cast anodes. This European Standard specifies 2 groups of cast magnesium alloy grades by a classification based on chemical composition. The first group deals with magnesium alloy ingots for anodes. The second group deals with magnesium alloy anode castings. This European Standard specifies chemical composition, designation, testing and inspection documentation. This European Standard does not cover technical delivery conditions for magnesium alloy anode castings (see EN 1559-1 [3] and EN 1559-5 [4]).

Copper and copper alloys - Ingots and castings
This European Standard specifies the composition, mechanical properties and other relevant characteristics of copper and copper alloys. The sampling procedures and test methods for the verification of conformity to the requirements of this standard are also specified. This European Standard is applicable to: a) copper alloy ingots intended to be remelted for later processing (e.g. castings); and b) copper and copper alloy castings which are intended for use without subsequent working other than machining. Recommended practice for the ordering and supply of castings is included in Annex A. Optional supplementary inspection procedures for ingots and castings are included in Annex B. NOTE Ingots are not suitable for pressure equipment applications.

Steels - Micrographic determination of the apparent grain size (ISO/DIS 643:2017)
This International Standard specifies a micrographic method of determining apparent ferritic or austenitic grain size in steels. It describes the methods of revealing grain boundaries and of estimating the mean grain size of specimens with unimodal size distribution. Although grains are three-dimensional in shape, the metallographic sectioning plane can cut through a grain at any point from a grain corner, to the maximum diameter of the grain, thus producing a range of apparent grain sizes on the two-dimensional plane, even in a sample with a perfectly consistent grain size.

Petroleum and natural gas industries - Steel drill pipe (ISO/DIS 11961:2017)
This International Standard specifies the technical delivery conditions for steel drill-pipes with upset pipe-body ends and weld-on tool joints for use in drilling and production operations in petroleum and natural gas industries for three product specification levels (PSL-1, PSL-2 and PSL-3). The requirements for PSL-1 form the basis of this International Standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3 are in Annex G. This International Standard covers the following grades of drill-pipe: grade E drill-pipe; high-strength grades of drill-pipe, grades X, G and S; enhanced H2S resistance drill pipe, grades D and F.

This part of ISO 10893 specifies requirements for film-based radiographic X-ray testing of the longitudinal or helical weld seams of automated fusion arc-welded steel tubes for the detection of imperfections. It can also be applicable to the testing of circular hollow sections. NOTE As an alternative, see ISO 10893-7 for digital radiographic testing.

Corrosion of metals and alloys - Accelerated cyclic test with exposure to acidified salt spray, dry and wet conditions (ISO/DIS 16151:2017)
This document specifies two accelerated corrosion-test procedures, Methods A and B, for the comparative evaluation of metallic materials with or without permanent corrosion protection or temporary corrosion protection in outdoor salt/acid rain environments. It also specifies the apparatus used. The two tests involve cyclic exposure of the specimens to acidified salt spray, “dry” and “wet” conditions. The particular advantages of the two tests over conventional accelerated tests, such as the neutral salt spray test (NSS) as specified in ISO 9227 lie in their better ability to reproduce the corrosion that occurs in outdoor salt and/or acid rain environments. They are also useful for evaluating cosmetic corrosion. Method A applies to — metals and their alloys, — metallic coatings (cathodic), — anodic oxide coatings, and — organic coatings on metallic materials. Method B applies to — steel coated with anodic coatings, and — steel coated with anodic coatings covered with conversion coatings.

The standard is applicable to steels for offshore structures, designed to operate in the offshore sector but not to steels supplied for the fabrication of subsea pipelines, risers, process equipment, process piping and other utilities. It is primarily applicable to the North Sea Sector, but may also be applicable in other areas provided that due consideration is given to local conditions e. g. temperature. NOTE There is an Annex F on the prequalification of steels for fixed offshore structures in arctic areas. Minimum yield strengths up to 690 MPa are specified together with low temperature impact properties at temperatures down to -40 °C.
