4 Designations
4.1 Material
4.1.1 General
The material is designated either by symbol or number (see Tables 1 to 8).
4.1.2 Symbol
The material symbol designation is based on the designation system given in ISO 1190-1.
NOTE Although material symbol designations used in this standard might be the same as those in other
standards using the designation system given in ISO 1190-1, the detailed composition requirements are not
necessarily the same.
4.1.3 Number
The material number designation is in accordance with the system given in EN 1412.
4.2 Material condition
For the purposes of this standard, the following designations, which are in accordance with the system
given in EN 1173, apply for the material condition:
M material condition for the product as manufactured without specified mechanical properties;
R. material condition designated by the minimum value of tensile strength requirement for the
product with mandatory tensile property requirements;
H. material condition designated by the minimum value of hardness requirement for the product
with mandatory hardness requirements.
NOTE 1 Products in the H. condition can be specified to Vickers or Brinell hardness. The material condition
designation H. is the same for both hardness test methods.
S (suffix) material condition for a product which is stress relieved.
NOTE 2 Products in the M, R. or H. condition can be specially processed (i.e. mechanically or thermally stress
relieved) in order to lower the residual stress level to improve the resistance to stress corrosion (see 6.5.2).
Exact conversion between the material conditions designated R. and H. is not possible.
Except when the suffix S is used, material condition is designated by only one of the above designations.
4.3 Product

be at the discretion of the supplier.
7 Sampling
7.1 General
When required (e.g. if necessary in accordance with specified procedures of a supplier's quality system,
or when the purchaser requests inspection documents with test results, or for use in cases of dispute),
an inspection lot shall be sampled in accordance with 7.2 and 7.3.
7.2 Analysis
The sampling rate shall be in accordance with Table 23. A test sample, depending on the analytical
technique to be employed, shall be prepared from each sampling unit and used for the determination of
the composition.
When preparing the test sample, care should be taken to avoid contaminating or overheating the test
sample. Carbide tipped tools are recommended; steel tools, if used, should be made of magnetic
material to assist in the subsequent removal of extraneous iron. If the test samples are in finely divided
form (e.g. drillings, millings), they should be treated carefully with a strong magnet to remove any
particles of iron introduced during preparation.
In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be
followed.
Results may be used from analyses carried out at an earlier stage of manufacturing the product, e.g. at
the casting stage, if the material identity is maintained and if the quality management system of the
manufacturer is certified, e.g. as conforming to EN ISO 9001.
7.3 Mechanical tests and stress corrosion resistance test
The sampling rate shall be in accordance with Table 23. Sampling units shall be selected from the
finished products. The test samples shall be cut from the sampling units. Test samples, and test pieces
prepared from them, shall not be subjected to any further treatment, other than any machining
operations necessary in the preparation of the test pieces.
8 Test methods
8.1 Analysis
Analysis shall be carried out on the test pieces, or test portions, prepared from the test samples
obtained in accordance with 7.2. Except in cases of dispute, the analytical methods used shall be
chemical or spectrographic according to EN or ISO standards in force. For expression of results, the
rounding rules given in 8.7 shall be used.
In cases of dispute concerning the results of analysis, the method of analysis to be used should be
chemical.
8.2 Tensile test
The tensile properties shall be determined in accordance with EN ISO 6892-1 on the test pieces
obtained in accordance with 7.3.
8.3 Hardness test
Hardness shall be determined on test pieces prepared from the test samples obtained in accordance
with 7.3. The test shall be carried out in accordance with either EN ISO 6506-1 or EN ISO 6507-1 and
the impression/indentation made on the outside surface, unless otherwise agreed. For the Brinell test
according to EN ISO 6506-1, a 0,102 F/D ratio of 10 shall be used.
8.4 Technological tests
8.4.1 Drift expanding test
When required, the drift expanding test shall be carried out in accordance with EN ISO 8493. The
outside diameter of the tube end shall be expanded by 30 % using a conical mandrel with an angle of
45°.
8.4.2 Stress corrosion resistance test
When required, the test method given in either EN ISO 196 or ISO 6957 shall be used on the test pieces
prepared from the test samples obtained in accordance with 7.3. The choice of which of these tests is
used shall be at the discretion of the supplier.
8.4.3 Average grain size determination
When required, the estimation of average grain size shall be carried out in accordance with
EN ISO 2624 or EN 16090.
8.5 Freedom from defects tests
When required, each tube shall be subjected to one of the following tests:
— Eddy current test for detection of local defects, in accordance with EN 1971-1 or EN 1971-2;
— Hydrostatic test;
— Pneumatic test.
If not otherwise agreed between the purchaser and the supplier, which of the test methods to be used
and the method of testing shall be at the discretion of the manufacturer.
8.6 Retests
8.6.1 Analysis, tensile, hardness, drift expanding and grain size tests
If there is a failure of one, or more than one, of the tests in 8.1, 8.2, 8.3, 8.4.1 or 8.4.3, two test samples
from the same inspection lot shall be permitted to be selected for retesting the failed property
(properties). One of these test samples shall be taken from the same sampling unit as that from which
the original failed test piece was taken, unless that sampling unit is no longer available, or has been
withdrawn by the manufacturer.
If the test pieces from both test samples pass the appropriate test(s), then the inspection lot
represented shall be deemed to conform to the particular requirement(s) of this standard. If a test piece
fails a test, the inspection lot represented shall be deemed not to conform to this standard.
8.6.2 Stress corrosion resistance test
If a test piece fails the test, the inspection lot represented by the failed test piece shall be permitted to
be subjected to a stress relieving treatment. A further test sample shall then be selected in accordance
with 7.3.
If a test piece from the further test sample passes the test, the stress relieved material shall be deemed
to conform to the requirements of this standard for residual stress level and shall then be subjected to
all the other tests called for on the purchase order, except for analysis. If the test piece from the further
test sample fails the test, the stress relieved material shall be deemed not to conform to this standard.
8.7 Rounding of results
For the purpose of determining conformity to the limits specified in this standard, an observed or a
calculated value obtained from a test shall be rounded in accordance with the following procedure,
which is based upon the guidance given in Annex B of ISO 80000-1:2009. It shall be rounded in one step
to the same number of figures used to express the specified limit in this standard, except that for tensile
)
2 1
strength and 0,2 % proof strength the rounding interval shall be 10 N/mm and for elongation the
value shall be rounded to the nearest 1 %.
The following rules shall be used for rounding:
