The control group according to GOST R 33259

On the flange marking in accordance with GOST 33259 there are Roman numerals I, II, III, IV, V. These figures indicate to which control group the flange belongs. Below is a table with a detailed description.

Control group	Batching conditions	Type and scope of testing	Delivery characteristics	Applicability
I	Billets of one steel grade	Chemical analysis – each melt	Chemical composition	For flanges PN ≤ 2,5 DN ≤ 300 for liquid working media not related to hazardous substances
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. IWC on request		For flanges PN> 160 all DN for all media
