It shows that the material meets both the AWS A5.1 standard and ASME SFA 5.1 standard.

These are the questions that sometimes drive me crazy. SFA is a universial classification system for filler materials. 5.1 is for carbon steel electrodes for SMAW, hence the designation E-6013. These type of specifications provide for uniform identification but I'll be darned if I know what "A/SFA" actually stand for. A wild guess: "A" - ASTM; "S"- Specification; "F"- Filler. (I've also seen it included with ASME classifications).

Hopefully someone will jump in and tell us!

I Think,

Materials with the A prefix are covered by an ASTM/AWS Specification. SFA Indicates adoption by ASME Sec II part C .

Material Specs Listed in the AWS publications can be viewed here http://www.aws.org/membership/sustainlibrary.pdf

ASME specs are listed prefixed with SFA. The following page has data taken from ASME Sec IX tables.http://www.weldinginspectionsvcs.com/f_numberlookup.asp

I found in the codes and standards volume one. "Most AWS filler metal specifications have been approved by ANSI as American National Standards and adopted by ASME. When ASME adopts an AWS filler metal specification, either in its entirety or with revisions, it adds the letter "SF" to the AWS alphanumeric designation. Thus, ASME sfa-5.4 specification would be similar, if not identical, to the AWS A5.4 specification." But that still doesn't tell me what it stands for.

SFA "standard filler association"????? do the letters have any meaning, or did they just pull them out of a hat. I woulnd' be suprised if they did pull them out of a hat.
