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. www.iso.org/directives

Introduction

This International Standard has been developed by users/purchasers and suppliers/manufacturers

completion accessories intended for use in the petroleum and natural gas industry worldwide. This

International Standard is intended to give requirements and information to both parties in the

selection, manufacture, testing and use of completion accessories. Further, this International Standard

addresses supplier/manufacturer requirements which set the minimum requirements with which

suppliers/manufacturers shall comply to claim conformity with this International Standard.

This International Standard has been structured to allow for grades of increased requirements both

in quality control and design validation. These variations allow the user/purchaser to select the grade

required for a specific application for a chosen accessory.

The three quality grades provide the user/purchaser the choice of requirements to meet a specific

preference or application. Quality grade Q3 is the minimum grade of quality offered by this product

standard. Quality grade Q2 provides additional inspection and verification steps, and quality grade Q1

is the highest grade provided. Additional quality requirements may be specified by the user/purchaser

as supplemental requirements.

Seven standard design validation grades (V0 to V6) provide the user/purchaser the choice of requirements

to meet a specific preference or application. Design validation grade V6 is the minimum grade and

represents equipment where the validation method has been defined by the supplier/manufacturer. The

complexity and severity of the validation testing increases as the grade number decreases.

Users of this International Standard should be aware that requirements above those outlined in this

International Standard may be needed for individual applications. This International Standard is not

intended to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting,

alternative equipment or engineering solutions. This may be particularly applicable where there is

innovative or developing technology. Where an alternative is offered, the supplier/manufacturer should

identify any variations from this International Standard.

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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 14998 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures

for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production

equipment.

ISO CD 14998
Introduction

This International Standard has been developed by users/purchasers and suppliers/manufacturers completion

accessories intended for use in the petroleum and natural gas industry worldwide. This International Standard

is intended to give requirements and information to both parties in the selection, manufacture, testing and use

of completion accessories. Further, this International Standard addresses supplier/manufacturer requirements

which set the minimum requirements with which suppliers/manufacturers shall comply to claim conformity with

this International Standard.

This International Standard has been structured to allow for grades of increased requirements both in quality

control and design validation. These variations allow the user/purchaser to select the grade required for a

specific application for a chosen accessory.

The three quality grades provide the user/purchaser the choice of requirements to meet a specific preference

or application. Quality grade Q3 is the minimum grade of quality offered by this product standard. Quality

grade Q2 provides additional inspection and verification steps, and quality grade Q1 is the highest grade

provided. Additional quality requirements may be specified by the user/purchaser as supplemental

requirements.

Seven standard design validation grades (V0 to V6) provide the user/purchaser the choice of requirements to

meet a specific preference or application. Design validation grade V6 is the minimum grade and represents

equipment where the validation method has been defined by the supplier/manufacturer. The complexity and

severity of the validation testing increases as the grade number decreases.

Users of this International Standard should be aware that requirements above those outlined in this

International Standard may be needed for individual applications. This International Standard is not intended

to inhibit a supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or

engineering solutions. This may be particularly applicable where there is innovative or developing technology.

Where an alternative is offered, the supplier/manufacturer should identify any variations from this International

Standard.

Introduction

La présente Nor me inter nat ionale a été élaborée par les ut ilisateurs/acheteurs et les four nisseurs/fabr icant s

d’accessoires de complétion à l’usage de l’industrie mondiale du pétrole et du gaz naturel. La présente

Norme internationale a pour but de fournir aux deux parties les exigences et les informations relatives à

la sélection, à la fabrication, aux essais et à l’utilisation des accessoires de complétion. La présente Norme

internationale indique en outre les exigences applicables aux fournisseurs/fabricants et établit les

exigences minimales auxquelles les fournisseurs/fabricants doivent satisfaire pour être en conformité

avec la présente Norme internationale.

La présente Norme internationale a été structurée de manière à tenir compte de niveaux croissants

d’exigences, tant en matière de maîtrise de la qualité que de validation de la conception. Ces variations

permettent à l’utilisateur/acheteur de choisir le niveau exigé pour une application spécifique d’un

accessoire donné.

Il existe trois niveaux de qualité permettant à l’utilisateur/acheteur de choisir les exigences répondant

à une préférence ou à une application spécifique. Le niveau de qualité Q3 représente la qualité minimale

proposée par la présente norme de produit. Le niveau de qualité Q2 prévoit des phases supplémentaires

de contrôle et de vérification, tandis que le niveau de qualité Q1 constitue le niveau le plus élevé.

L’utilisateur/acheteur peut spécifier des exigences de qualité supplémentaires.

Il existe également sept niveaux normalisés de validation de la conception (V0 à V6) qui permettent à

l’utilisateur/acheteur de choisir les exigences répondant à une préférence ou à une application spécifique.

Le niveau V6 est le niveau minimal de validation de la conception; il s’applique à des équipements dont la

méthode de validation a été définie par le fournisseur/fabricant. La complexité et la sévérité des essais

de validation augmentent en fonction du niveau.

Il convient que les utilisateurs de la présente Norme internationale soient conscients du fait que des

exigences supérieures à celles décrites dans la présente Norme internationale peuvent être nécessaires

pour des applications particulières. La présente Norme internationale n’a pas pour intention d’empêcher

un fournisseur/fabricant de proposer, ou un utilisateur/acheteur d’accepter, un équipement ou

une solution technique différente. Cela peut notamment s’appliquer dans le cas d’une technologie

innovante ou en cours de développement. Lorsqu’une autre solution est proposée, il convient que le

fournisseur/fabricant identifie les écarts par rapport à la présente Norme internationale.
