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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

AMENDMENT 1
4.3.1
Replace the first two sentences in the first paragraph with the following:
Materials shall be either
— in conformance with an internationally recognized standard (see Annex A), or
— in conformance with this subclause.
Materials shall be compatible with the process fluid. Materials and combination of materials shall be
selected such that galling, frictional heating, and galvanic corrosion are avoided.
Replace the first sentence in the second paragraph with the following:
For materials that are not in conformance with an internationally recognized standard (see Annex A), the
materials shall be controlled by the manufacturer of the pressure-relief valve by a specification ensuring
control of chemical content and physical properties and quality at least equivalent to an internationally
recognized standard.
