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).

Introduction
The purpose of this document is to provide a general set of rules for brazing procedure qualification
independent of product or application.
All new brazing procedure tests are to be carried out in accordance with this document from the date of
its issue. However, this document does not invalidate previous brazing procedure tests made to former
standards or specifications.
Where additional tests need to be carried out to make the qualification technically equivalent, it is only
necessary to perform the additional tests on a test piece which should be made in accordance with this
document.
