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
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso
.org/iso/foreword .html.
This document was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical
delivery conditions for steel tubes for pressure purposes.
This second edition cancels and replaces the first edition (ISO 10893-6:2011), which has been
technically revised. The main changes compared with the previous edition are as follows:
a) evidences about film overlap have been included in 4.7;
b) a safety warning for X and gamma rays has been added at the end of Clause 4;
c) Figure 2 has been aligned with ISO 17636-1 up to 1 000 kV;
d) film side position and location have been clarified in Clause 6;
e) requirements for film processing have been specified in Clause 7;
f) a reference to ISO 5580 has been added in Clause 8;
g) the figures in Annex A have been revised.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

3.1
tube
hollow long product open at both ends, of any cross-sectional shape
3.2
welded tube
tube (3.1) made by forming a hollow profile from a flat product and welding adjacent edges together,
and which after welding can be further processed, either hot or cold, into its final dimensions
3.3
manufacturer
organization that manufactures products in accordance with the relevant standard(s) and declares the
conformity of the delivered products with all applicable provisions of the relevant standard(s)
3.4
agreement
contractual arrangement between the manufacturer (3.3) and the purchaser at the time of enquiry
and order
4 General requirements
4.1 Unless otherwise specified by the product standard or agreed on by the manufacturer and
the purchaser, a radiographic inspection shall be carried out on tubes after completion of all the
primary production process operations (rolling, heat treating, cold and hot working, sizing, primary
straightening, etc.).
4.2 This inspection shall be carried out by trained operators who are certified (e.g. ISO 9712) or
qualified (e.g. ISO 11484 or ASNT SNT-TC-1A), and supervised by competent personnel nominated by
the manufacturer. In the case of third-party inspection, this shall be agreed on between the manufacturer
and the purchaser.
The operating authorization issued by the employer shall be according to a written procedure. Non-
destructive testing (NDT) operations shall be authorized by a level 3 NDT individual approved by the
employer.
NOTE The definitions of level 1, 2 and 3 can be found in the appropriate International Standards, e.g.
ISO 9712 and ISO 11484.
4.3 The tubes under test shall be sufficiently straight and free of foreign matter as to ensure the validity
of the test. The surfaces of the weld seam and adjacent parent metal shall be sufficiently free of such
foreign matter and surface irregularities, which can interfere with the interpretation of the radiographs.
Surface grinding is permitted in order to achieve an acceptable surface finish.
4.4 In cases where the weld reinforcement is removed, markers, usually in the form of lead arrows,
shall be placed on each side of the weld such that its position can be identified on the radiograph.
4.5 Identification symbols, usually in the form of lead letters, shall be placed on eac
