Introduction
This document was developed in response to worldwide demand for stabilizing the quality assurance for
titanium and titanium alloys by common regulations worldwide.
Determining condition concerning the technical delivery conditions for bar, rod and billet of titanium and
titanium alloys, such as chemical composition, mechanical properties and dimensional tolerance is
extremely important to promote commerce of titanium and titanium alloys products in the global market.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that
compliance with this document may involve the use of patents concerning titanium alloys given in Table 1
and Table 2.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this
respect, the statement of the holder of this patent right is registered with ISO. Information may be
obtained from the patent database available at www.iso.org/patents. www.iso.org/patents.

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those in the patent database. ISO shall not be held responsible for identifying any
or all such patent rights.

e) inspection;
f) mill product certificate;
g) certification. (document issued and/or validated by an independent third party that assures that a
product meets specified requirements such as a purchase order).
4.2 Options
A number of options are specified in this document and listed below. In the event that the purchaser does
not indicate a wish to implement any of these options at the time of enquiry and order, the bar, rod or
billet shall be supplied in accordance with the basic specification.
a) restrictive chemistry (see 6.2);
b) product analysis (see 6.2);
c) special mechanical properties (see 6.3);
d) special tolerance (see 6.4);

6.2 Chemical composition
The bar, rod and billet of titanium and titanium alloys shall conform to the chemical requirements

manufacture of titanium sponge, ingot, or mill product.
The content of any element intentionally added to the formulation of the heat shall be reported.
Other elements are those not specified in the relevant designated material such as Cr and Mo of Ti1-
0,18Pd and those not originally specified in the Table 1 such as Co and Hf. Generally, other elements
include aluminium, vanadium, tin, molybdenum, chromium, manganese, zirconium, nickel, copper,
silicon, cobalt, tungsten, hafnium and yttrium except for alloying elements contained in the designation.
The element which is taken as the other element shall be subjected to the agreement between the

Other elements should not be reported unless the content is greater than 0,1 % for each, or 0,4 % for
total. The content of yttrium should not be reported unless the content is greater than 0,005 % for each.
When agreed upon between the manufacturer and the purchaser and specified in the purchase order,
other specific residual elements not listed in Table 1 may be added and their content shall be reported.
The chemical analysis shall be conducted by the standard techniques normally used by the manufacturer
and the purchaser. In case of disagreement, the test methods defined in ASTM E2371 or ASTM E539 shall
be used as the referee method except for carbon, oxygen and hydrogen, which are not covered in these
standards. Test methods defined in ISO 22960, ISO 22961 or ISO 22962 may be used as the referee
method for iron instead of ASTM E2371/ or ASTM E539. The test method defined in ASTM E1409 shall
be used as a referee method for oxygen and nitrogen, and ISO 22963 may be used as a referee method
for oxygen. The test method defined in ASTM E1447 shall be used as a referee method for hydrogen and
the test method defined in ASTM E1941 shall be used as a referee method for carbon.

ISO/FDIS 7217:2022(E)
Introduction
This document was developed in response to worldwide demand for stabilizing the quality assurance
for titanium and titanium alloys by common regulations worldwide.
Determining condition concerning the technical delivery conditions for bar, rod and billet of titanium
and titanium alloys, such as chemical composition, mechanical properties and dimensional tolerance
is extremely important to promote commerce of titanium and titanium alloys products in the global
market.
The International Organization for Standardization (ISO) draws attention to the fact that it is claimed
that compliance with this document may involve the use of patents concerning titanium alloys given in
Table 1 and Table 2.
ISO takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured ISO that he/she is willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In
this respect, the statement of the holder of this patent right is registered with ISO. Information may be
obtained from the patent database available at www.iso.org/patents.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those in the patent database. ISO shall not be held responsible for identifying
any or all such patent rights.

Other elements are those not specified in the relevant designated material such as Cr and Mo of Ti1-
0,18Pd and those not originally specified in the Table 1 such as Co and Hf. Generally, other elements
include aluminium, vanadium, tin, molybdenum, chromium, manganese, zirconium, nickel, copper,
