Indicated values are given as average values of properties and they do not constitute specification

At the consumer's request coefficient of flowability can be determined within a range from 1.6 to 2.8 with accuracy ± 0.2, for example Cf=1.8±0.2

The dimensions and shape of briquettes of electrode paste are provided with the shape of molds:

Geometrical dimensional fnd weight of SBEP and LBEP blocks (including reference of two pairs of non-through (blind) holes for gripping blocks by load-lifting mechanisms) are provided with equipment and are not regarded as rejection values. The hollows after shrinkage of paste during LBEP cjjling are not regulated/

SBEP can be shipped in (750±50)kg Big Bags.
