This part of this European Standard specifies technical delivery conditions for hot-finished seamless, electric welded and submerged arc welded steel structural hollow sections for mechanical engineering purposes of circular, square, rectangular or elliptical forms.
It applies to hollow sections formed hot, with or without subsequent heat treatment, or formed cold with subsequent heat treatment above 580 °C to obtain equivalent mechanical properties to those obtained in the hot formed product.
NOTE 1   The requirements for tolerances, dimensions and sectional properties are specified in EN 10210-2.
NOTE 2   The attention of users is drawn to the fact that whilst cold formed grades in EN 10219-3 can have equivalent mechanical properties to hot-finished grades in EN 10210-3 the sectional properties of square and rectangular hollow sections in EN 10210-2 and EN 10219-2 are not equivalent.
NOTE 3   A range of material grades is specified in this document and the user should select the grade most appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are generally comparable with those in EN 10025-2, EN 10025-3, EN 10025-4, EN 10025-5 and EN 10025-6.
NOTE 4   The requirements for seamless and welded steel structural hollow sections for use in offshore structures are covered in EN 10225.
NOTE 5    Spiral welded hollow sections are to be used with caution in construction of dynamic behaviour (fatigue stress) where up to now, there is insufficient knowledge of their performance.

Part 2 of this document, in addition to Part 1, specifies the technical delivery conditions for flat and long products and semi-finished products which are meant for further processing to flat and long products of hot rolled non-alloy quality steels in the grades and qualities given in Tables 2 to 6 (chemical composition) and Tables 7 to 9 (mechanical properties) in the delivery conditions as given in 6.3. Three engineering steels are also specified in this document (see Tables 3 and 5) (chemical composition) and Table 8 (mechanical properties). This document does not apply to structural hollow sections and tubes (see EN 10210-1 and EN 10219-1).
The technical delivery conditions apply to thicknesses > 3 mm and < 150 mm for long products of steel grade S450J0. The technical delivery conditions apply to thicknesses < 250 mm for flat and long products of all other grades and qualities. In addition for flat products of qualities J2 and K2 the technical conditions apply to thicknesses < 400 mm.
Products made of steel grades S185, E295, E335 and E360 cannot be CE marked.
The steels specified in this Part 2 are not intended to be heat treated except products delivered in delivery condition +N. Stress relief annealing is permitted (see also the NOTE in 7.3.1.1 of EN 10025-1:2004). Products delivered in +N condition can be hot formed and/or normalized after delivery (see Clause 3).
NOTE 1   Semi-finished products which are to be converted to rolled finished products conforming to this document should be the subject of special agreement at the time of the enquiry and order. The chemical composition can also be agreed at the time of the order, however the values should be within the limits of Tables 2 and 3.
NOTE 2   For certain grades and product forms suitability for particular applications may be specified at the time of the enquiry and order (see 7.4.2, 7.4.3 and Table 10).

This European Standard specifies an inductively coupled plasma optical emission spectrometry routine method for the analysis of unalloyed and low alloyed steels, whose iron content shall be at least 95 %.
This method is applicable to the elements listed in Table 1 within the ranges shown.
Table 1 - Application ranges
(...)
In all cases, the ranges specified can be extended or adapted (after validation) for the determination of other mass fractions, provided that the iron content in the samples under concern is above 95 %.
Other elements may be included. However such elements and their mass fractions should be carefully checked, taking into account the possible interferences, the sensitivity, the resolution and the linearity criteria of each instrument and each wavelength.
Depending also on the sensitivity of each instrument, suitable dilutions of the calibration and the test sample solutions may be necessary.
Moreover, even if the method described is "multi elemental", it is not absolutely necessary to carry out the determination of all the elements of its scope simultaneously: the measurement conditions have to be optimised by each laboratory, depending on the performances of each apparatus available.
NOTE 1   The accuracy of the method is unsatisfactory for phosphorus contents from 0,05 to 0,1 %.
NOTE 2   The trueness of the method couldn't be checked for vanadium contents below 0,05 %.
NOTE 3   The precision of the method is unsatisfactory for aluminium (total) contents below 0,02 %.

This draft European Standard specifies the technical delivery requirements for seamless and welded butt welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of carbon and alloy steel in two test categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases.
It specifies:
a)   type of fittings;
1)   type A: Butt-welding fittings with reduced pressure factor;
2)   type B: Butt-welding fittings for use at full service pressure;
b)   steel grades and their chemical compositions;
c)   mechanical properties;
d)   dimensions and tolerances;
e)   requirements for inspection and testing;
f)   inspection documents;
g)   marking;
h)   protection and packaging.
NOTE   In the case of a harmonised supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.
