Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not

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 plate, sheet and strip 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, Table 2 and Table 3.
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.

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 plate, sheet and strip of titanium

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, Table 2 and Table 3.
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.

3.1
plate
flat-rolled product of rectangular cross-section with uniform thickness over 5 mm, supplied in straight
lengths (i.e. flat) usually with sheared, sawn or flame-cut/plasma-cut edges or water jet cutting
Note 1 to entry: The thickness does not exceed one-tenth of the width.
3.2
sheet
flat-rolled product of rectangular cross-section with uniform thickness over 0,20 mm and up to and
including 5 mm inclusive, supplied in straight lengths (i.e. flat) usually with sheared or sawn edges or
water jet cutting

usually with slit edges
Note 1 to entry: The thickness does not exceed one-tenth of the width.
Note 2 to entry: In some English-speaking countries, “strip” is called “coiled sheet”.
4 Information to be supplied by the purchaser
4.1 General information
The purchase order shall include the following information:
a) quantity (e.g. total mass or total length);
b) designation;
c) dimensions;
d) packaging;

5 Manufacturing
The plate, sheet and strip shall be manufactured by hot-working or hot-rolling of ingot or intermediate
product followed by appropriate cold-rolling, if necessary, and surface conditioning and heat treatment.
The plate, sheet and strip shall be supplied as solid wrought product with uniform cross-section in
straight shape or in coiled form.
6 Requirements
6.1 General
When supplied in the delivery condition indicated in 4.1 and inspected in accordance with Clause 7, the
plate, sheet and strip shall conform to the requirements of this document.
6.2 Chemical composition
The plate, sheet and strip of titanium and titanium alloys shall conform to the chemical requirements
prescribed in Table 1.
The elements listed in Table 1 are either intentional alloy additions or elements that are inherent to the
manufacture of titanium sponge, ingot or mill product.
The content of any element intentionally added to the formulation of 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
purchaser and the manufacturer, and shall be noted in the purchase order.
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. The 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.
