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).

Zerstörungsfreie Prüfung - Ultraschallprüfung von Stäben aus Stahl

Diese Europäische Norm legt ein Verfahren für die manuelle Ultraschall-Impuls-Echo-Prüfung von Stäben aus Stahl mit einem Durchmesser oder einer gleichwertigen Dicke bis 400 mm fest. Mechanisierte, halbautomatische und automatische Techniken dürfen angewendet werden, sollten aber zwischen Besteller und Lieferer vereinbart werden.

Essais non destructifs - Contrôle par ultrasons des barres en acier

La présente norme européenne spécifie les méthodes manuelles de contrôle par ultrasons et par réflexion des barres en acier de diametre ou épaisseur inférieur ou égal a 400 mm. Les techniques mécanisées, semi-automatisées ou automatisées peuvent etre utilisées mais il convient qu'elles fassent l'objet d'un accord entre fournisseur et acheteur.

EN 10308:2001 (E)3ForewordThis European Standard has been prepared by Technical Committee ECISS/TC 2 "Steel - Physico-chemical andnon-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of an identical text orby endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest byMay 2002.Annex A is informative.This standard includes a Bibliography.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries 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.SIST EN 10308:2002

For the purposes of this European Standard, the following terms and definitions given in EN 1330-4 apply, together with the following.3.1manual testingtesting by an operator applying an ultrasonic probe, or probes, to the product surface, manually executing theappropriate scanning pattern on the product surface and assessing ultrasonic signal indications on the electronicequipment screen either by direct viewing or by built-in signal amplitude alarm devices3.2automatic and semi-automatic testingtesting using a mechanised means of applying the ultrasonic probe or probes to, and executing the appropriatescanning pattern on the flat product surface, together with ultrasonic signal indication evaluation by electronicmeansNOTESuch testing can be either fully automatic with no operator involvement, or semi-automatic when the operatorperforms basic equipment operation functions.A list of equivalent terms in several European languages in given in annex A.SIST EN 10308:2002

EN 10308:2001 (E)54 Items for agreementsThe following aspects concerning ultrasonic testing shall be agreed between the purchaser and supplier at the timeof 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 inclauses 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 PrincipleThe method used is based on the reflection of ultrasonic waves (generally longitudinal), the direction of which isapproximately 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 theamplitude of the echo of a flat-bottomed hole of a given diameter and located at the same depth as thediscontinuity.NOTEOnly 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 areaswith the required sensitivity level.The examination is carried out during the first ultrasonic scan (first back wall echo) for all the product thicknesses ordiameter and from one side only.SIST EN 10308:2002
