This document describes a method of determining the hole expansion ratio in metallic sheets and strips with a thickness range of 1,2 mm to 6,0 mm inclusive and a width of at least 90 mm. NOTE This test is normally applicable to sheet metal and is used to assess the suitability of the product for forming flanges.

This document specifies a method of measuring the case hardening depth, surface hardening depth, nitriding hardness depth and total thickness of surface hardening depth obtained, e.g. thermal (flame and induction hardening, electron beam hardening, laser beam hardening, etc.) or thermochemical (carbonitriding, carburizing and hardening, hardening and nitriding, etc.) treatment.

This document specifies the ring hydraulic pressure test for metallic tubes. It is generally applied to tubes with an outside diameter greater than 120 mm and outside diameter to thickness ratio of not less than 20. The objective of this test is to ascertain the value of the hoop stress required to produce a specified total circumferential (hoop) strain.

This document specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming, of steels for construction and of steels with high proof strength for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), zinc-magnesium alloy (ZM), aluminium-silicon alloy (AS) or aluminium (A) and for continuously hot-dip coated products made of multiphase steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA) or zinc-magnesium alloy (ZM) in thicknesses of 0,20 mm ≤ t ≤ 6,5 mm. By agreement at the time of enquiry and order, this document is applicable to continuously hot-dip coated flat products of an expanded validity range defined for thicknesses t < 0,20 mm with agreed mechanical properties and test specimens, adhesion of coating and surface condition requirements. This document applies to strip of all widths and to sheets cut from it (≥600 mm width) and cut lengths (<600 mm width). NOTE The products covered by this document are used where cold formability, high strength, a defined minimum yield strength and/or corrosion resistance are the most important factors. Corrosion resistance of the product is depending on coating type and coating thickness, hence to its mass (see also 7.3.2). The products covered by this document can be used as substrates for organic coated flat products specified in EN 10169 for building and general engineering applications.

This document is applicable to the determination of brittle crack arrest temperature(CAT) of rolled steel plates with thickness not greater than 200 mm. This standard specifies the requirements for test method and test procedures when using the isothermal crack arrest test to judge a valid test result under isothermal conditions and in order to determine the crack arrest temperature.

This document specifies the nominal dimensions and masses of the hot rolled steel channels, I and H sections. The following shapes are covered by this document: Sections: - parallel flange I sections IPE; - parallel wide flange beams HE; - parallel extra wide flange beams HL and HLZ; - parallel wide flange columns HD; - parallel wide flange bearing piles HP and UBP; - parallel flange universal beams UB; - parallel flange universal columns UC; - taper flange I sections IPN and J. Channels: - parallel flange channels UPE and PFC; - taper flange channels UPN, U and CH. These requirements do not apply to hot rolled steel channels, I- and H- sections from stainless steel.

This document specifies requirements for phased array ultrasonic examination of steel castings with low ultrasonic attenuation. It is applicable to ferritic, bainitic and martensitic microstructures. It specifies the registration levels and acceptance criteria. This document applies to the ultrasonic examination of steel castings with a wall thickness of 600 mm or less. For higher wall thicknesses, special agreements apply regarding the test procedure and recording levels. This document does not apply to austenitic steels and cast irons, lamellar graphite and spheroidal cast irons and welded assemblies. For other ferrous materials, this document gives guidance. The registration levels and acceptance criteria are to be adapted. In this document, phased array is used both for phased array technique and TFM technique.

 This document specifies a method for the determination of the hydrogen-reducible oxygen content of metallic powders containing mass percentage of 0,05 % to 3 % oxygen.

This document is applicable to unalloyed, partially alloyed or completely alloyed metal powders and also to mixtures of carbides and binder metal.

This document is not applicable to powders containing lubricants or organic binders. This document can be extended to powders containing carbon by the use of a special catalytic device. This document is intended to be used in conjunction with ISO 760 and ISO 4491-1.

This document specifies the maximum mass content of alloying elements and impurities in aluminium and aluminium alloy cast materials and articles designed to be in contact with foodstuff. It contains provisions for the demonstration of conformity of products with the present document. NOTE Materials include ingots and liquid metal. Articles are finished goods.
