     FAQ:

     1. Products standards:

    'EU Construction Products Directive': EN 14199:2005 Micropiles and EN 14490:2010 Soil Nails.

       2. What the EU standards require?

     EN 14199:2005 "Micropiles", clause 6.2.1 and EN 14490:2010 "Soil Nails", clause 6.2.2.2 require:

     Yield Stress, fyk, between 400 to 600 MPa (60 to 87 ksi)

     Ductility (Elongation Agt > 5% required by EN 10080, ASASTM A615 , ASASTM A370)

     All the required properties above are tested of Finished hollow-bar, NOT raw materials.

       3. What is Agt?

     Agt denotes the elongation up to ultimate load without reduction of cross-section.

     It is not to be confused with total elongation, A, up to rupture.

     Usually elongation, A, has double the value of Agt. 

       4.  What is the standard of quality for SDA? Is the higher the strength, the better?

     No, the grade of material strength is based on its yield strength. However, for the Grade of Product Quality, the key index should be its ductility (i.e. the values of Agt and Rm/Rp0.2, according to Eurocode EC2).
