II Billets of the same steel grade, jointly heat treated Chemical analysis – each melt. 
Hardness measurement – 5% batch, 
but not less than 5 pcs. 
IWC on request 		Chemical composition. 
Hardness 		For flanges PN ≤ 6 all DN and for flanges PN ≤ 16 DN ≤ 300 for non-hazardous media
III Billets of the same steel grade, heat-treated in the same mode Chemical analysis – each melt. 
Hardness measurement – each billet. 
Unbrakable control – 
at the request of the customer. 
IWC on request 		Chemical composition. 
Hardness 		For flanges PN ≤ 25 all DNs for non-hazardous media. 
For flanges PN ≤ 6 DN ≤ 150 
for liquid working media related to hazardous substances
IV Chemical analysis – each melt. 
Hardness measurement – each billet. 
Mechanical properties – 1% of each set, 
but not less than 2 pcs. 
Non-destructive testing – each piece. 
IWC on request 		Chemical composition. 
Hardness. 
Mechanical properties (yield strength, relative narrowing, impact strength). 
Resistance to ICC 		For flanges PN ≤ 160 all DN for all media
V Individually each blank Chemical analysis – each melt. 
Hardness measurement – each billet. 
Mechanical properties – each billet. 
Non-destructive testing – each piece.
