    18、the machine construction;c) checking to make sure machine complies with all technical specifications for that type of machine;d) calibration of measuring systems if steps a) to c) have positive results.1) Testing machines outside the scope of this standard include machines for non-destructive testin

    24、on on test houses and laboratoriesIn Germany, materials testing machines are verified by testing agencies under the direction of the Federal andLnder governments. Lists containing the names and addresses of these agencies, as well as the types oftesting machines and the measuring range limits up to

    25、which they can test, are available from the Verband derMaterialprfungsmter (VMPA) (German Association of Materials Testing Agencies) (Offices: Agastr. 24,12489 Berlin, Germany).As a result of current developments within the European Market and the publication of DIN EN ISO/IEC 17025,the verification

    26、 and calibration of materials testing machines can now be carried out by private companiesaccredited either by the Akkreditierstelle des Deutschen Kalibrierdienstes (Offices: Physikalisch-TechnischeBundesanstalt (German Federal Institute for Science and Technology), Bundesallee 100, 38116 Braunschwe
