This document specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel. This Part of EN 10216 can also be applied for tubes of non-circular cross section; necessary modification will be agreed at the time of enquiry and order. NOTE Once the reference of this document is published in the Official Journal of the European Union (OJEU) under Directive 2014/68/EU, pressure equipment Directive, presumption of conformity to the Essential Safety Requirements (ESR) of Directive 2014/68/EU is limited to technical data of materials in this document 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 the Pressure Equipment Directive are satisfied, needs to be done by the designer of the pressure equipment, taking also into account the subsequent manufacturing processes which could affect properties of the base materials.

This document specifies the dimensions of an unnotched impact test piece of sintered metal materials.
The test piece may be obtained directly by pressing and sintering or by machining a sintered part.
This document applies to all sintered metals and alloys, with the exception of hardmetals. However, for certain materials (for example, materials with low porosity or materials with high ductility), it may be more appropriate to use a notched test piece which, in this case, will give results with less scatter. (In
this case, refer to ISO 148-1.)
NOTE For porous sintered materials, the results obtained from impact tests on unnotched specimens according to this standard are not fully comparable with results obtained from tests on solid metals tested on notched specimens.

This document specifies the mechanical properties of wrought aluminium and wrought aluminium alloy finstock.
The chemical composition limits of these materials are specified in EN 573-3, unless otherwise agreed between supplier and purchaser.
The designations of wrought aluminium and wrought aluminium alloys and the temper designations used in this document are specified in EN 573-3, and the temper designations are defined in EN 515.

The International Standard specifies a method for evaluating the deposition on real structures and equipment by wiping them from their surfaces. Depositions become corrosion and/or degradation factors of the metals, alloys, and organic materials and shall be analyzed quantitatively to control
corrosion and degradation of real structures and equipment.
This method is especially suitable for evaluating the kind and amount of deposition on real structures and equipment in all industries. This method delivers types and instantaneous values of the watersoluble and insoluble deposition concentrations explained as an unit of weight per area without the
time component and gives knowledge of environmental factors against corrosion and degradation.
Water-soluble depositions detected by this method include not only chloride ion but also sulfate ion and other ions to understand the synergistic and antagonistic effects for the corrosion acceleration.
This document is applicable to
— metals and their alloys exposed in various environment
— metallic coatings exposed in various environment
— organic coatings exposed in various environment
— concreates and other structural materials exposed in various environment
NOTE Measurement method of chloride on cleaned surfaces to make sure the cleanness of the steel substrates after surface preparation such as grinding, polishing, cleaning, and rinsing, and before application of paints are given in ISO 8502.

This document specifies technical requirements for hot rolled stainless steel plain bars and ribbed bars to be used as reinforcement in concrete. It is applicable to steel delivered in the form of bars, coils and de-coiled products. It does not apply to ribbed bars produced from finished products
The production process is at the discretion of the manufacturer.

This document specifies the technical delivery conditions for corrosion-resistant alloy seamless tubular products for casing, tubing, coupling stock and accessory material (including coupling stock and accessory material from bar) for two product specification levels:
— PSL-1, which is the basis of this document;
— PSL-2, which provides additional requirements for a product that is intended to be both corrosion and cracking resistant for the environments and qualification method specified in Annex G and in the ISO 15156 series.
At the option of the manufacturer, PSL-2 products can be provided in lieu of PSL-1.
NOTE 1 The corrosion-resistant alloys included in this document are special alloys in accordance with ISO 4948-1 and ISO 4948-2.
NOTE 2 For the purpose of this document, NACE MR0175 is equivalent to the ISO 15156 series.
NOTE 3 Accessory products can be manufactured from coupling stock and tubular material, or from solid bar stock or from bored and heat heat-treated bar stock as covered in Annex F.
This document contains no provisions relating to the connection of individual lengths of pipe.
This document contains provisions relating to marking of tubing and casing after threading.
This document is applicable to the following five groups of products:
a) group 1, which is composed of stainless alloys with a martensitic or martensitic/ferritic structure;
b) group 2, which is composed of stainless alloys with a ferritic-austenitic structure, such as duplex and super-duplex stainless alloy;
c) group 3, which is composed of stainless alloys with an austenitic structure (iron base);
d) group 4, which is composed of nickel-based alloys with an austenitic structure (nickel base);
e) group 5, which is composed of bar only (Annex F) in age-hardened (AH) nickel-based alloys with austenitic structure.
NOTE 4 Not all PSL-1 categories and grades can be made cracking resistant in accordance with the ISO 15156 series and are, therefore, not included in PSL-2.

This document specifies the chemical composition limits of wrought aluminium and wrought aluminium alloys and form of products.
NOTE The chemical composition limits of aluminium and aluminium alloys specified herein are completely identical with those registered with the Aluminium Association, 1525, Wilson Boulevard, Suite 600, Arlington, VA 22209, USA, for the corresponding alloys.

This document specifies the requirements and definitions for the essential characteristics of prestressing bars, which are used for the prestressing of concrete and which are delivered as finished products in the form of:
— hot rolled and processed bars;
— plain and threaded bars.
NOTE 1 The specification of manufacturing processes related to the finished product is required to ensure that the essential characteristics can be tested properly and that test results are valid. It is not possible to anticipate that any other manufacturing process leads to products which can be tested properly with the specified test methods. Thus, a conclusion to the safe application in building construction would not any longer be possible for those products.
This document does not apply to:
— galvanized steel;
— epoxy coated steel;
— reinforcing steel (see EN 10080);
— further processing.
NOTE 2 Example for further processing: Plain bars are also applied in systems for the prestressing of concrete with threaded ends. The threaded ends depend in length and type on the intended use of the system and are manufactured downstream in the supply chain.

This document specifies requirements for non-alloy and alloy steels that are intended for cold heading or cold extruding and are delivered as wire rods, wire or bars. It also contains specific requirements
for:
— steels not intended for heat treatment, with diameters from 2 mm to 100 mm (see Annex A);
— case-hardening steels with diameters from 2 mm to 100 mm (see Annex B);
— steels for quenching and tempering, including boron-alloyed steels (see Table C.3), with diameters from 2 mm to 100 mm (see Annex C);
This document (except Annex A) is applicable to the properties of cold-headed or cold-extruded parts which have been subjected to a subsequent heat treatment. As the properties of the parts in the coldheaded
or cold-extruded, and subsequently not-heat-treated condition, are largely dependent on the applied cold-heading or cold-extruding conditions, these are, if necessary, subject to agreement between the purchaser and the manufacturer of the parts.
