Introduction This document proposes harmonised verification test conditions for the qualification of welding consumables for aluminium. The responsibility to identify the extent of the tests to be carried out lies with the manufacturer/supplier on the basis of his assessment of the market requirements. It should be noted that tests in accordance with this document are made in a way, which is not necessarily representative of a real welded structure. The requirements for the qualification of welding consumable manufacturers, suppliers and distributors are given in EN 12074.

Retests
If the results of any test fail to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimens for retest may be taken from the original test assembly or from a new test assembly using parent metals of the same type, welding consumables from the same production lot and the same welding procedure as used for the first test assembly. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this specification for that classification. In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the weld test assembly or test specimen(s) or in conducting the test, the test shall be considered invalid, without regard to whether the test was actually completed or whether the test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling the number of test specimens does not apply.

10 Certificate After successful completion of the r elevant tests, a type qualification cer tificate of the welding consumable is issued according to Annex E on the basis of the type qualification test report.
11 Extension of the range of qualification If the range of qualification of the welding consumable shall be extended, appropriate tests related to the extension shall be performed.
12 Modification of the welding consumable If the qualified welding consumable has been modified so that the characteristic values are outside the information which are given according to 5.2 the necessary tests shall be performed to dem onstrate that the product still complies with the requirements agreed for the range of qualification.
13 Transfer of qualification The transfer of qualification of one trade name to another trade name shall be documented. Formats are given in Annex F and Annex G. For products for which the production is transferred to another factory on the basis of the same specifications the manufacturer shall demonstrate compliance with the classification or product specification by deposited metal and welded joint tests.

Annex I (informative) Qualification under the supervision of the test body ` , , , ` ` , ` ` , , ` , , ` , ` , , ` -
I.1 Introduction Test and evaluation for the qualification of welding consumables are carried out under the responsibility of the manufacturer/supplier and, at his request, under the supervision of a test body. It is recommended that the following are agreed between the manufacturer /supplier and the test body.
I.2 Conformity of the product The manufacturer or supplier shall declare the conformity of the product by identifying the test body on the label with the qualification number. Procedures for maintaining the qualifications are given in I.4. The methods for conformity assessment deemed suitable for welding consumables are in accordance with the "Global Approach for Certification and Testing" 1. (from the introduction) If required by directives, application standards or other technical rules and regulations the conformity of product shall be tested in accordance with the requirements specified by the holder of the certificate. Necessary information specified in 5.2 shall be submitted to the test body. Sampling, testing and verification of product properties shall be carried out under the supervision of the test body.
I.3 Marking of products The test body shall verify that the marking of the product and the packaging is in accordance with EN ISO 544. When other markings replacing the product name are used, such markings shall be unique and unambiguous and are entered into the qualification certificate. Production lots manufactured after the type qualification shall be marked with the test body identity on the packaging label of the smallest packaging unit.
I.4 Certificate After successful completion of the relevant tests and test report, the test body issues a type qualification certificate of the welding consumable according to Annex E on the basis of the type qualification test report.
I.5 Transfer of qualifications I.5.1 If a supplier wishes to market under his own product name a welding consumable already tested elsewhere, he shall apply for this in writing to the test body which carried out the type qualification test.
1 93/465/EWG - Resolution of the council of July 22nd, 1993 on the modules to be used in the technical directives of
harmonization for the various phases of the conformity evaluation (Official Journal of the EC No L 220, Aug. 30th, 1993, p.23 ff).

EN 14532-3:2004 (E)
I.5.2 Both the manufacturer of the qualified welding consumable and the supplier shall declare in writing to the test body that the welding consumable delivered to the supplier is identical to that which has already been tested. Both parties shall immediately inform the appropriate body should the contractual relationship be terminated (see Annexes F and G). I.5.3 The supplier will receive the type qualification certificate for the welding consumable which will not mention that it is a transfer. The products of several manufacturers shall not be combined under one product name of the supplier unless the product is traceable by the test body to the manufacturer.
I.6 Prolongation of the type qualification of welding consumables The test body shall extend the validity of the certificate of a qualified welding consumable after a period not exceeding two years provided the following requirements are met a) The manufacturer's in-plant testing system (see EN 12074, EN ISO 9001) is shown to be adequate; b) The necessary tests as defined in this document (see Annex H) have been carried out and documented by the inspection department of the manufacturer, independent of the production. If for any reasons the above requirements are not met a corrective action programme shall be agreed between the manufacturer and the test body. If the agreed corrective action programme is not implemented the qualification will be withdrawn.
I.7 Dormant welding consumables type qualification ` , , , ` ` , ` ` , , ` , , ` , ` , , ` -
The validity of a type qualification may be suspended at the manufacturer's request. If the manufacturer subsequently applies for the dormant type qualification to be revived the application shall be accepted if the following conditions are fulfilled. a) no changes according to 5.2 have occurred compared with the original type qualification; b) on restarting production the welding consumable shall be tested by means of one set of tests specified in Annex H in the presence of the test body.
