Products are made and controlled according to technological normative documents. The foil that is made fron one ingot, status of materiel and thickness is considered to be a consignment .
The foil is delivered in unannealed condition. The surface of the foil must be cleanm, without cracks, declines, folds, exfoliation and reach-through holes. Little scratchs, hairlines, blisters, roll marks and dimples caused by way of production, if their depth of deposition doesn't take the foil out the deviation limit of thickness are allowed .
