Evaluation of welded joints in aluminium and its alloys by radiography — Acceptance levels F: This document specifies acceptance levels for indications corresponding to imperfections in aluminium butt welds detected by radiographic testing. Descriptors Technical International Thesaurus: Modifications Corrections Published and distributed by Association Fran? NF EN classification index: Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN Management Centre or to any CEN member.
A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. 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of an identical text or by endorsement, at the latest by Februaryand conflicting national standards shall be withdrawn at the latest by February Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
EN Non-destructive testing of welds comprises a series of European Standards for acceptance levels for radiographic testing which is made up of the following parts: Evaluation of welded joints in steel, nickel, titanium and their alloys by radiography 12157-1 Acceptance levels Part 2: If agreed, the acceptance levels may be applied to other types of welds or materials.
The acceptance levels may be related to welding standards, application standards, specifications or codes. This European Standard assumes that the radiographic testing has been carried out in accordance with EN When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of imperfections permitted by standards are compared with the dimensions of indications revealed by a radiograph made of the weld. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document including any amendments applies. Fusion welding ISO The acceptance levels in this European Standard are basically valid for evaluation of imperfections which cannot be detected and evaluated by visual testing Table 2. Surface imperfections Table 3; such as undercut and eb penetration, surface damage, weld spatter, etc.
This shall be specified. The symbols used in Tables 2 and 3 are the following: Any two adjacent imperfections separated by a distance smaller than the major dimension of the smaller imperfection shall be considered as a single imperfection.

Indications shall not be divided into different ranges L. See Annex C, Figure C. The acceptance levels are those defined for visual testing. Reliable detection of all cracks is therefore limited. E use of radiographic technique B or better, as specified in ENwill provide better crack detectability than radiographic technique A.
Lack of side wall fusion will probably not be detected except it is associated with other imperfections eh as slag inclusions unless it is radiographed in direction of the side wall.
This should assist the assessment of imperfections on radiographs and fracture surfaces.

The sum of the different pore areas? If D is smaller than the smaller diameter of one of the neighbouring pores, the full connected area of the two pores is dn be taken into the sum of imperfections Figure C.
If D is smaller than the shorter length of one of the neighbouring imperfections, the full connection of the two imperfections is to be taken into the sum of imperfections Figure C.
