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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 9333 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 2, Prosthodontic
materials.
This second edition cancels and replaces the first edition (ISO 9333:1990), subclauses 4.1 and 4.4 of which
have been technically revised:
a) in 4.1 by the introduction of upper limits for cadmium, beryllium and lead;
b) in 4.4 by a reduction in the mechanical strength of a brazed joint;
c) further, the requirement for flow temperature has been cancelled.

4 Requirements
4.1 Chemical composition
4.1.1 Reported composition
For all elements that are present in excess of 1,0 % (mass fraction), the percentage by mass of each of the
constituent elements shall be declared by the manufacturer and shall be reported as instructed in 8 c) to a
precision of 0,1 % (mass fraction). Any element that is present in a concentration in excess of 0,1 % (mass
fraction), but not in excess of 1,0 % (mass fraction), shall be identified as instructed in 8 c) either by name or
symbol.
4.1.2 Permitted deviation from the reported composition
For silver-based or noble-metal-based brazing materials the percentage of each of the constituents shall not
deviate by more than 0,5 % (mass fraction) from the values stated in the manufacturer's or distributor's
instructions for use [see 8 c)].
For base-metal-based brazing materials, all elements present with more than 20 % (mass fraction) shall not
deviate from the value stated in the manufacturer's or distributor's instructions for use by more than 2% (mass
1% 20 %
fraction). Those present in excess of (mass fraction) but not in excess of (mass fraction) shall not

fraction) [see 8 c)].
4.1.3 Hazardous elements
4.1.3.1 Recognised hazardous elements
For the purposes of this document the elements nickel, cadmium, beryllium and lead are designated to be
hazardous elements.
4.1.3.2 Permitted limits for hazardous elements
The brazing material shall not contain more than 0,02 % (mass fraction) of cadmium or beryllium or lead. If the
brazing material contains more than 0,1 % (mass fraction) of nickel, the percentage shall not exceed the
amount indicated on the package [see 9.2 e)] or insert [see 8 d)].
4.2 Biocompatibility
Specific qualitative and quantitative requirements for freedom from biological hazard are not included in this
International Standard but it is recommended that, in assessing possib
