ISO 15616-1:2003 高品質の溶接および切断用のCO2レーザービームマシンの受け入れテスト—パート1：一般原則、受け入れ条件 | ページ 2

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.

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 part of ISO 15616 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 15616-1 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 10, Unification of requirements in the fielsd of metal welding, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

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

ISO 15616 consists of the following parts, under the general title Acceptance tests for CO₂-laser beam machines for high quality welding and cutting:

• Part 1: General principles, acceptance conditions
• Part 2: Measurement of static and dynamic accuracy
• Part 3: Calibration of instruments for measurement of gas flow and pressure

Foreword

This document (EN ISO 15616-1:2003) has been prepared by Technical Committee CEN/TC 121,"Welding", the secretariat of which is held by DS, in collaboration with ISO/TC 44"Welding and allied processes".

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 September 2003, and conflicting national standards shall be withdrawn at the latest by September 2003.

This European Standard “Acceptance test for CO₂ – laser beam machines for high quality welding and cutting” consists of the following Parts:

• Part 1: General principles, acceptance conditions.
• Part 2: Measurement of static and dynamic accuracy.
• Part 3: Calibration of instruments for measurement of gas flow and pressure.

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, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovak Republic, Spain, Sweden, Switzerland and the United Kingdom.

1 Scope

This Part of this European Standard is applicable to CO₂-laser beam machines for welding and cutting in two operating directions (2D).

The main purpose of this standard is to provide requirements for acceptance testing of CO₂-laser beam machines prior to or during installation at the user’s premises. The acceptance tests are used to document the ability of CO₂-laser beam machines to produce welded joints and cuts of consistent quality.

This standard is intended to be used for preparation of the technical specification for CO₂-laser beam machines for high quality welding and cutting in two operating directions (2D). This standard specifies basic requirements. Additional tests and requirements may be specified in the technical specification for the CO₂- laser beam machine.

However, the standard may also be used for testing as part of maintenance, as appropriate.

If modifications are made to a CO₂-laser beam machine (rebuilding, repairs, modifications to the operating conditions etc.) that may have an effect on the acceptance testing, repeat test may be necessary covering the machine parameters affected by such modifications.

If a CO₂-laser beam machine that has already been accepted is dismantled (e.g. in order to change its location) such tests may involve verification according to the requirements in 6.4 as a minimum.

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3 Terms, definitions and symbols

For the purposes of this Part of this European Standard, the terms and definitions given in EN ISO 11145:2001, EN ISO 11146:1999 and in the International Vocabulary of Basic and General Terms in Metrology apply.

The symbols listed in Table 1 are used in this standard.
