Petroleum, petrochemical and natural gas industries - Internal coating and lining of steel storage tanks (ISO 16961:2015)

ISO 16961:2015 specifies the minimum requirements for surface preparation, materials, application, inspection and testing of internal coating lining systems that are intended to be applied on internal surfaces of steel storage tanks of crude oil, hydrocarbons and water for corrosion protection.
It covers both new construction and maintenance works of tank internal coating and lining as well as the repair of defective and deteriorated systems.
ISO 16961:2015 also provides the minimum requirements for shop performance testing of the coated/lined samples and the criteria for their approval.

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

Introduction

This International Standard is based on GSO 2057 – 2010 (E). The objectives of this International

Standard are to define minimum technical requirements for the corrosion protection by coating and

lining of internal surfaces of steel storage tanks, to provide technical guidance for developing local

standards and specifications, and to ensure compliance in coating and lining material selection and

performance with contract requirements.

Users of this International Standard should be aware that further or differing requirements can be

needed for individual applications. This International Standard is not limiting the contractor and/or

manufacturer from proposing or the company from accepting alternative engineering solutions for

the individual application. This can be particularly applicable where there is innovative or developing

technology. Where an alternative is proposed, the specification issuer should identify any deviations

from this International Standard and provide details.
Annexes A, B, C and D of this International Standard are informative only.

INTERNATIONAL STANDARD ISO 16961:2015(E)
Petroleum, petrochemical and natural gas industries —
Internal coating and lining of steel storage tanks
1 Scope

This International Standard specifies the minimum requirements for surface preparation, materials,

application, inspection and testing of internal coating lining systems that are intended to be applied on

internal surfaces of steel storage tanks of crude oil, hydrocarbons and water for corrosion protection.

It covers both new construction and maintenance works of tank internal coating and lining as well as

the repair of defective and deteriorated systems.

This International Standard also provides the minimum requirements for shop performance testing of

the coated/lined samples and the criteria for their approval.
2 Conformance
2.1 Rounding

Unless otherwise stated in this International Standard, to determine conformance with the specified

requirements, observed or calculated values shall be rounded to the nearest unit in the last right-

hand place of figures used in expressing the limiting value, in accordance with ISO 80000-1:2009,

Annex B, Rule A.

NOTE For the purpose of this provision, the rounding method of ASTM E29–08 is equivalent to

ISO 80000-1:2009, Annex B, Rule A.
2.2 Compliance to this International Standard

A quality system should be applied to assist compliance with the requirements of this International

Standard. ISO/TS 29001 gives sector-specific guidance on quality management systems.

The applicator shall comply with all of the applicable requirements of this International Standard.

It shall be permissible for the client to make any investigations necessary in order to be ensured of

compliance by the applicator and to reject any material that does not comply.
