1 Scope This document applies to welding consumables for which supplementary qualification is required. It contains the technical requirements to be fulfilled. These supplementary tests apply for welding consumables, where the primary qualification is available in accordance with EN 14532-1. The supplementary tests can be carried out at any time without the need to repeat the primary tests. This document describes the testing methods, the amount of testing and the requirements for supplementary qualification of welding consumables. 2 Normative references The following referenced documents are indispensable for the application of this document.

SIST EN 14532-2:2005

4.2.2.4 Conditions for test specimens and testing The all-weld metal tensile test specimens of ferritic welding consumables may be exposed to a temperature not exceeding 250 ºC for a period not exceeding 16 h for hydrogen removal prior to testing, alternatively a temperature not exceeding 105 ºC for a time not to exceed 48 h may be used. Tensile test specimens shall be of 10 mm diameter in accordance with EN 876. For all-weld metal, the test should be carried out in accordance with EN 10002-1 or EN 10002-5 and the tensile strength, lower yield strength or proof strength, elongation after fracture (A5) and reduction of area shall be determined. For all groups of welding consumables, tested at all temperatures, the 0,2 % proof strength shall be determined, except in the case of consumables for non alloy and fine grain steels tested at room temperature (23 ± 5) ºC when the lower yield strength shall be determined. The requirements at room temperature and at elevated temperatures are given in Annex C, depending on the material groups according to CR ISO 15608:2000, for which the consumable is intended to be verified. For verification of strength at elevated temperatures with welding consumables for oxy-acetylene welding the test assembly should be prepared in accordance with Annex D. SIST EN 14532-2:2005

The composition shall be within the range of the all-weld metal of a covered electrode or gas shielded metal arc welding consumable subjected to creep rupture testing.
1) Other recognised public domain sources of parent material mean creep rupture data may alternatively be used as reference data subject to technical review. The source of reference data should be given on the test certificate. SIST EN 14532-2:2005

be carried out using a test assembly as specified in EN 1597-1. The minimum gauge diameter shall be 8 mm, except for legacy test data.
NOTE Gauge diameters of at least 10 mm are recommended to limit data scatter. The test specimen axis shall be aligned with the direction of welding. Constant load creep rupture testing shall be carried out at a selected fixed temperature within the range (T to T+100) °C, where T is the maximum application temperature for whi
