Brazing - Brazer approval

Asnjë informacion i shtuar.

This European Standard for the approval testing of brazers (as defined in 3.1) specifies basic requirements essential to the brazing process, test conditions, assessment and certificates. Because of the wide range of applications of brazing this standard does not specify detailed acceptance criteria as these are product-specific and have in each case to be agreed prior to the contract (see clause 4). It is anticipated that, where necessary, specific requirements for individual industries will be developed within this framework and detailed in the relevant application standard. The recommended format for the certificate of approval testing is given in annex A. With regard to the approval test, the brazer should be required to show adequate practical experience and knowledge of the brazing processes, materials and safety requirements for which he is to be approved to a written procedure. This standard applies to hand torch (flame) brazing and only to approval of brazers whose manipulative skills have a direct bearing on the outcome and effectiveness of the brazed joint. It does not apply to those who are not required to apply manipulative skill, since such approval is not normally necessary. If a special professional education and examination in the domestic field included brazing, this standard does not apply to a brazer while he is employed in that field. The certificate of approval testing is issued under the sole responsibility of the examiner or examining body.
