1) In addition to the steelslisted, all unalloyedsteels in the same strengthclass but designated in accordance with another steels standard are also considered to be coveredby the approval certificate. This also appliesto steels supplied in differentdelivery conditions (e.g. S690Q DIN EN 10025-6 also includes S700MC DIN EN 10149-2).

2) The approval certificate applies to steelswith the deliverycondition codes NL, ML or QL only if the required Charpy V-notch impact energy is included as part of the relevant standardised material desig- nation.

3) The approvalcertificate only appliesto materials that lie within the range for the upper yield strength (ReH) specified in the section“Scope of approval certificate”.

4) The approval certificate also appliesto the welding of load-bearing butt welded joints in reinforcing steel (as specified in DIN EN ISO 17660-1,7.2) if in the relevant standardised material designation the code number indicating yield strength is at least “50”.

2.   Scope of approval certificate in the case of cold-wirefeeder systems and hybridweld- ing processes:

If a certified GMAW wire electrode is fed as “cold wire” (e.g. 52 with cold wire feeding)or if a hybrid welding process is used (e.g. 52 / 135), the scope of the approvalcertificate with respect to materialsis the same as that for the certified GMAW process.

 

3.   Build-up welding:

Approval applies only to the tested material listed under “Scope of approvalcertificate” or for the specified hardness.

 

4.   Rail steels:

4.1    Rail joint welding:

In addition to the tested rail steel listed under “Scope of approval certificate” and designated in accordance with the DIN EN 13674-1standard, all rail steels of lower strengthare also considered to be coveredby the approvalcertificate, including rail steels designated in accordance with other relevant standards.

Note:

The final 10 mm below the top of the rail shall be welded with a filler metal that has been approved for build-upwelding (rail resurfacing) work on the rail steel.

4.2   Rail resurfacing by welding:

Approval applies only to the tested rail steel listed under “Scope of approvalcertificate” and designated in accordance with the DIN EN 13674-1,including rail steels of the same hardness designated in accordance with other relevant standards.
