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

This document supplements API Spec 5L, 46 edition (2018).
The technical requirements of this document and API Spec 5L used to be identical (except for the
inclusion of Annex M in the ISO publication). In the meantime API Spec 5L has been technically revised
th
as API Spec 5L, 46 edition (2018). The purpose of this document is to bring it up to date, by referencing
the current edition of API Spec 5L and including supplementary content.
The main changes compared to the previous edition are as follows:
— Technical changes now incorporated by normative reference to API Spec 5L have been made in the
API Spec 5L subclauses addressing
— weld seams (API Spec 5L, 8.8.2 clarifies heat treatment),
— tolerances for straightness (API Spec 5L, 9.11.3.4b and J.6.4 pipe end tolerances tightened),
— end squareness (API Spec 5L, 9.12.6 defined in detail),
— impact test pieces (API Spec 5L, Table 22 test piece size table corrected),
— location of hardness tests (API Spec 5L, Figures H.1 and J.1 weld centre line for HFW detailed),
— welded jointers (API Spec 5L, Annex M fit up and geometry, marking & NDT addressed),
