Gives some recommendations for the correct interpretation of the results obtained. The test methods are applicable generally to all powders of metals, alloys, carbides and mixtures thereof. The constituents of the powder shall be non-volatile and free of lubricant or organic binder. The limitations of the methods which depend upon the nature of the analysed metal are discussed in clause 4.

This document 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 document are also specified. This document 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.

ISO 9477:2015 specifies requirements for four grades of heat treated cast carbon and alloy steels for general engineering and structural purposes.


In cases where castings are produced by welding component parts together, this International Standard does not cover the welding process or the properties of the weldment.


The four steel grades are intended for service at ambient temperature. However, properties at other temperatures can be agreed on through the use of supplementary requirements in ISO 4990.

This document specifies the technical delivery conditions for qualities TR1 and TR2 of electric welded and submerged arc welded tubes of circular cross section, with specified room temperature properties, made from non-alloy quality steel. NOTE 1 Quality TR2 is intended to support the essential requirements of EU Directive 2014/68/EU in respect of pressure equipment with specified room temperature properties (see Table 5). NOTE 2 Once this standard is published in the Official Journal of the European Union (OJEU), presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to the technical data for the materials in this standard and does not presume adequacy of the material for a specific item of pressure equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of a specific item of equipment to verify that the ESRs of the Pressure Equipment Directive are satisfied, needs to be done by the designer or manufacturer of the pressure equipment, taking also into account any subsequent processing procedures which may affect properties of the base materials.

1.1 This document specifies general requirements and definitions for the essential characteristics of weldable reinforcing steel used for the reinforcement of concrete structures, delivered as finished products in the form of: - bars (including those produced by the reinforcing steel manufacturer from coil); - coils; - sheets of factory-made machine-welded fabric; - lattice girders. 1.2 Steels according to this document have a ribbed, indented or smooth surface. NOTE 1 The protrusions between indentations of indented reinforcing steel have the same function as transverse ribs of ribbed reinforcing steel. There is no definition which specifies the difference between ribbed and indented surface geometry. Therefore, in this document, the same bond parameters are used for ribbed and indented steel. 1.3 This document does not apply to: - non-weldable reinforcing steel; - galvanized reinforcing steel; - epoxy-coated reinforcing steel; - corrosion resistant reinforcing steel; - prestressing steels; - indented strip; - further processing by a processor, e.g. de-coiling/straightening, cutting or cutting and bending. NOTE 2 Further processing could influence some essential characteristics of the product.

This European Standard is intended to define the test methods used for the determination of the following geometrical characteristics of electrical steel sheet and strip: — edge wave (wave factor); — residual curvature; — edge camber; — deviation from the shearing line due to internal stresses; — burr height of cut edges. This European Standard applies to electrical steel sheet and strip intended for the construction of magnetic circuits and corresponding to Clauses B2, C21 and C22 of IEC 60404-1:2000.

ISO 4990:2015 specifies the general technical delivery requirements for the supply of steel, nickel, and cobalt alloy castings, including the requirements for the selection and preparation of samples and test pieces.


When a material or product standard differ from this delivery specification, the material or product standard shall apply. In the case of investment castings, ISO 16468 will apply.


This International Standard also specifies a group of supplementary requirements which may be applied to steel, nickel, and cobalt alloy castings. These requirements are provided for use when additional testing or inspection is desired and apply only when individually specified by the purchaser.
