test category 5 Classification and designation 5.1 Classification In accordance with the classification system in EN 10020, the steel grades P195GH, P235GH and P265GH are classified as non-alloy quality steels and the other steel grades are classified as alloy special steels. 5.2 Designation 5.2.1 For the tubes covered by this Part of EN 10216, the steel designation consists of:  the number of this Part of EN 10216; plus either:  the steel name in accordance with EN 10027-1; or:
 the steel number allocated in accordance with EN 10027-2. 5.2.2 The steel name of non-alloy steel grades is designated by:  the capital letter P for pressure purposes;  the indication of the specified minimum yield strength at room temperature for wall thickness less than or equal to 16 mm, expressed in MPa
(see Table 4);  the symbols GH for elevated temperature. 5.2.3 The steel name of alloy steel grades is designated by the chemical composition (see Table 2) and the symbols for the heat treatment, where specified in column 3 and footnote c of Table 1. 6 Information to be supplied by the purchaser 6.1 Mandatory information The following information shall be supplied by the purchaser at the time of enquiry and order: a) the quantity (mass or total length or number); b) the term "tube"; c) the dimensions (outside diameter D and wall thickness T or a set of dimensions covered by Option 11) (see Table 6); d) the designation of the steel grade in accordance with this Part of EN 10216 (see 5.2);
Unless option 1 is specified, the tubes may be either hot or cold finished at the discretion of the manufacturer. The terms “ hot finished “ and “ cold finished “ apply to the condition of the tube before it is heat treated in accordance with7.3.3. Option 1: The tubes shall be cold finished before heat treatment. 7.2.3 The tubes shall be supplied in the relevant heat treatment conditions as specified in Table 1. SIST EN 10216-2:2014
