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

This document was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.
This second edition cancels and replaces the first edition (ISO 11177:2016), which has been technically
revised. The following change has been made:
— in 5.6, the normative reference has been changed from ISO 28706-2 to ISO 28706-1:2008, Clause 9,
“Class AA”.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The requirements defined in this document regarding the product quality of enamelled valves
and pressure pipe fittings for untreated and potable water supply take into account the real stress
conditions to which a component can be subjected in the course of its operating life. Typical types of
stress are
— during storage: climate, UV radiation, mechanical stress,
— during transportation: mechanical stress, e.g. at certain points (impact), laterally (friction),
— during preparation for installation: cleaning agents, mechanical stress, e.g. at certain points
(impact), laterally (friction),
— during installation: mechanical stress, and
— during operation: abrasion caused by the carried medium, corrosion from surrounding medium,
mechanical stress from shifting ground loads, UV radiation with valves built in above ground.
