Wadm was determined with a fastener with axial loading resistance Roc = 1458 N,
To determine Wadm for other combinations (other substrate and other fastener) the following formula and conditions
apply:
If Rnc ≥ Roc then Wadm, nc = Wadm, oc
If Rnc < Roc then Wadm, nc = (Rnc/Roc) × Wadm,oc
The application of the full scale test results for systems with other fasteners (Rnc) and/or substrates according to annex 2
of this ETA, a separate ETA or Fastener PASS issued on the basis of ETAG 006, is possible if:
• The plates are protected against corrosion;
• The minimal thickness of the metallic plates is:
o 0.75 mm, if they are ribbed,
o 1,00 mm, if they are flat.
In the new system, the use of plates that are different from those in the reference system is possible under the following
conditions:
• The steel plates are permitted with their resistance R determined in the whole system,
• The metal grades and thicknesses are higher or equal to those of reference ones,
• The dimensions of washers comply with the conditions in the following Table.
Round washers

oc = original combination (tested)
nc = new combination

The fasteners have to be in conformity with the specifications given in section 1.1.2 and annex 2 of this ETA, an ETA
delivered on the basis on the ETAG 006 or a FASTENER PASS FOR MEFAWAME ETA – Intermediate evaluation in
compliance with the European Technical Approval Guideline n°006.
