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 3.

Draft International Standards adopted by the technical committees are circulated to member bodies for voting. Publication as an International Standard requires approval by at least 75 % of member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this part of ISO 14922 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

International Standard ISO 14922-2 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 107, Metallic and other inorganic coatings, Subcommittee SC 5, Thermal spraying, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

Throughout the text of this standard, read"...this European Standard..." to mean"...this International Standard...".

ISO 14922 consists of the following parts, under the general title Thermal spraying — Quality requirements of thermally sprayed structures:

• Part 1: Guidance for selection and use
• Part 2: Comprehensive quality requirements
• Part 3: Standard quality requirements
• Part 4: Elementary quality requirements

Annex ZA provides a list of corresponding International and European Standards for which equivalents are not given in the text.

Foreword

The text of EN ISO 14922-2:1999 has been prepared by Technical Committee CEN/TC 240"Thermal spraying and thermally sprayed coatings", the secretariat of which is held by DIN, in collaboration with Technical Committee ISO/TC 107"Metallic and other inorganic coatings".

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 1999, and conflicting national standards shall be withdrawn at the latest by December 1999.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope

This standard specifies requirements so that:

• It is independent of the type of the thermally sprayed structure.
• It defines quality requirements for thermal spraying both in workshops and on site.
• It provides guidance for describing a manufacturer's capability to produce thermally sprayed constructions to meet specified requirements.
• It may also be used as a basis for assessing the manufacturer in respect to his thermal spraying capability.This standard is appropriate when demonstration of a manufacturer's capability to produce thermally sprayed construction, fulfilling specified quality requirements, are specified in one or more of the following:
• a contract between involved parties;
• an application standard;
• a regulatory requirement.The requirements contained within this standard may be adopted in full or may be selectively deleted by the manufacturer if not applicable to the construction concerned. They provide a flexible framework for the control of thermal spraying in the following cases:
• Case 1To provide specific requirements for thermal spraying in contracts which require the manufacturer to have a quality system in accordance with EN ISO 9001 or EN ISO 9002.
• Case 2To provide specific requirements for thermal spraying in contracts which require the manufacturer to have a quality system other than EN ISO 9001 or EN ISO 9002.
• Case 3To provide specific requirements for thermal spraying in contracts which require the manufacturer developing a quality system.
• Case 4To provide specific requirements for thermal spraying in application standards which uses thermal spraying as part of its requirements or in a contract between relevant parties. It may however be more appropriate for EN ISO 14922-3 or EN ISO 14922-4 to be used in such cases.
