Non destructive testing - Ultrasonic testing of steel bars
Part 5 of this document, in addition to part 1, specifies requirements for flat and long products of hot rolled steels with improved atmospheric corrosion resistance in the grades and qualities given in Tables 2 and 3 (chemical composition) and Tables 4 and 5 (mechanical properties) in the usual delivery conditions as given in 6.3.
The thicknesses in which products of the steel grades and qualities specified in this document may be supplied are given in Table 1.
In addition to EN 10025-1:2004 the steels specified in this document are especially intended for use in welded, bolted and riveted components which shall have enhanced resistance to atmospheric corrosion, for service at ambient temperatures (subject to the restrictions described in 7.4.1).
The steels specified in this Part 5 are not intended to be heat treated except products delivered in the 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).

Foreword
This European Standard has been prepared by Technical Committee ECISS/TC 2 "Steel - Physico-chemical and
non-destructive testing", the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest by
May 2002.
Annex A is informative.
This standard includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,
Switzerland and the United Kingdom.
1 Scope
This European Standard describes the techniques to be used for the manual, pulse-echo, ultrasonic testing of steel
bars of diameter or equivalent thickness less or equal to 400 mm or equivalent section. Mechanised,
semi-automatic or automatic techniques may be used but should be agreed between the purchaser and the
supplier.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

3 Terms and definitions
Definitions for general terms of non-destructive testing can be found in other European Standards, e.g. EN 1330-1
and EN 1330-2. For the purposes of this European Standard, the following terms and definitions given in EN 1330-
4 apply, together with the following.
3.1
manual testing
testing by an operator applying an ultrasonic probe, or probes, to the product surface, manually executing the
appropriate scanning pattern on the product surface and assessing ultrasonic signal indications on the electronic
equipment screen either by direct viewing or by built-in signal amplitude alarm devices
3.2
automatic and semi-automatic testing
testing using a mechanised means of applying the ultrasonic probe or probes to, and executing the appropriate
scanning pattern on the flat product surface, together with ultrasonic signal indication evaluation by electronic
means
NOTE Such testing can be either fully automatic with no operator involvement, or semi-automatic when the operator
performs basic equipment operation functions.
A list of equivalent terms in several European languages in given in annex A.
4 Items for agreements
The following aspects concerning ultrasonic testing shall be agreed between the purchaser and supplier at the time
of the enquiry or order:
a) the manufacturing stage(s) at which ultrasonic testing shall be performed (see clause 10);
b) the volume(s) to be tested and whether grid scanning coverage or complete scanning coverage is required
(see clause 13);
c) the Quality Class required, or the Quality Classes and the zones to which they apply (see clause 15);
d) the applicable evaluation level and acceptance criteria if different from those detailed in Tables 2 and 3;
e) whether any special scanning coverage, equipment or couplant is required in addition to that detailed in
clauses 8 and 13;
f) the scanning technique to be used if not manual;
g) the sizing techniques to be used for extended discontinuities (see clause 16);
h) the technique(s) to be used for setting sensitivity (see clause 12);
i) whether the test is to be conducted in the presence of the purchaser or his representative;
j) whether a written procedure shall be submitted for approval by the purchaser (see clause 6).
5 Principle
The method used is based on the reflection of ultrasonic waves (generally longitudinal), the direction of which is
approximately perpendicular to the surface of the product. The examination consists of:
a) locating and evaluation of discontinuity by comparing the amplitude of the discontinuity echo with the
amplitude of the echo of a flat-bottomed hole of a given diameter and located at the same depth as the
discontinuity.
NOTE Only those discontinuities giving an echo in amplitude equal to or greater than that obtained with the reference flat-
bottomed hole are taken into consideration.
b) determining the area of the discontinuity according to the – 6 dB beam width technique.
If areas with particular permeability are located, the testing conditions shall be adjusted in order to test these areas
with the required sensitivity level.
The examination is carried out during the first ultrasonic scan (first back wall echo) for all the product thicknesses or
diameter and from one side only.
6 Procedure
The inspection is normally carried out in the place of production or on the premises of the supplier. If specified on
1)
the order, the inspection may take place in the presence of the purchaser or his representative .
Ultrasonic testing shall be performed in accordance with a written procedure. Where specified in the enquiry or
order, the written procedure shall be submitted to the purchaser for approval prior to testing.
This written procedure shall be in the form of:
a) a product specification or;
b) a procedure written specifically for the application or;
c) this European Standard may be used if it is accompanied by examination details specific to the application.
The procedure shall contain the following details as a minimum requirement:
a) description of the item to be examined;
b) reference documents;
c) qualification and certification of examination personnel;
d) stage of manufacture at which the examination is carried out;
e) examination zones specified in terms of the applicable Quality Classes;
f) any special preparation of scanning surfaces, if applicable;
g) couplant;
h) description of examination equipment;
i) calibration;
j) scanning plan;
k) description and sequence of examination operations;
l) recording level ;
m) characterisation of disco
