Oil and gas industries including lower carbon energy — Internal coating of carbon steel process vessels — Part 2: Requirements and guidance for the selection of coating systems
This document specifies the criteria and minimum requirements for selecting internal coatings (often referred to as linings) for pressurized service within process vessels. The document provides the following: — key factors influencing coating selection; — generic composition of test liquids which can be used as references when evaluating supporting testing evidence for coatings; — principal test methods to be used as evidence of performance when selecting suitable coatings; — supporting evidence to be used in evaluating coatings that is relevant to the potential end use. This document covers types of coatings that are generally available, with properties that are known and documented. It also covers other materials to be evaluated and qualified for use. This document is applicable to process vessels coated at the new construction phase. It can be applied only where the coating is applied directly to the substrate. This document does not cover requirements related to metallic coatings nor weld overlay materials.
Industries du pétrole et du gaz, y compris les énergies à faible teneur en carbone — Revêtement de protection interne des récipients de production en acier au carbone — Partie 2: Exigences et recommandations pour le choix des systèmes de revêtement
Le présent document spécifie les critères et les exigences minimales de choix des revêtements internes (souvent désignés en tant que doublures) pour le service sous pression à l'intérieur des récipients de production. Le document fournit les éléments suivants: — facteurs clés influençant le choix du revêtement; — composition générique des liquides d'essai qui peut être utilisée comme référence lors de l'évaluation des preuves d'essai à l'appui des revêtements; — principales méthodes d'essai à utiliser comme preuve de performance lors du choix des revêtements appropriés; — preuves à l'appui à utiliser dans l'évaluation des revêtements qui sont pertinentes pour l'utilisation finale potentielle. Le présent document couvre des types de matériaux qui sont généralement disponibles et qui ont des propriétés connues et documentées. Il couvre également d'autres matériaux à évaluer et qualifier pour utilisation. Le présent document s'applique aux récipients de production revêtus lors de la phase de construction des équipements neufs. Il peut être appliqué uniquement lorsque le revêtement est appliqué directement sur le subjectile. Le présent document ne couvre pas les exigences relatives aux revêtements métalliques ni aux matériaux de recouvrement des soudures.

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

Introduction
By providing requirements and guidance for the selection of coating materials, this document:
— - ensures the long-term performance of coating materials.
— - ensures that coating materials selected meet the needs of a broad range of end users in the oil and gas
industries.
— - enables coating manufactures to develop and provide coatings that meet the requirements of this
document.
Oil and gas production projects benefit from a structured evaluation of coatings performance for the different
process liquids and gases being handled within process vessels.
The main objective of this document is to provide general requirements with guidance for the selection of
coatings for the internal surfaces of process vessels, with due consideration to the liquids and gases contained
within the vessel and the impact of the external environment. Particular attention is paid to key parameters
such as operating temperature, pressure, and presence of abrasion, amongst others. It is the end user's
responsibility to provide a project document with respect to the implementation of the requirements and
guidance of this document, and to specify the design conditions for coating selection. In addition to the end
user, the organization responsible for the facility or for the process equipment design, or for both, is regarded
as responsible for coating selection.
This document is developed to provide responsible parties with a structured process to carry out evaluation
of proposed coatings in a consistent manner as a part of the engineering work, with a design basis for a
particular installation or equipment item. Further this document is intended for use by oil companies and
engineering contractors. Further or differing requirements can be needed for individual applications.

Oil and gas industries including lower carbon energy — Internal

Part 2:
Requirements and guidance for the selection of coating systems
1 Scope
This document specifies the criteria and minimum requirements for selecting internal coatings (often referred
to as linings) for pressurized service within process vessels. The document provides the following:
— — key factors influencing coating selection;
— — generic composition of test liquids which can be used as references when evaluating supporting
testing evidence for coatings;
— — principal test methods to be used as evidence of performance when selecting suitable coatings;
— — supporting evidence to be used in evaluating coatings that is relevant to the potential end use.
This document covers types of coatings that are generally available, with properties that are known and
documented. It also covers other materials to be evaluated and qualified for use.
This document is applicable to process vessels coated at the new construction phase. It can be applied only
where the coating is applied directly to the substrate.
This document does not cover requirements related to metallic coatings nor weld overlay materials.
