| Resumen: | Introduction This European Standard specifies the requirements for materials to be used for the manufacture of seals and diaphragms. It specifies for that purpose, tests to be carried out on standardized test pieces taken from sheets of material, since the small size of most components does not, in general, allow for the necessary standard samples to be prepared from them in order to undertake the complete range of tests. It may be necessary to carry out supplementary tests on the component mounted in the gas appliance, or in equipment, to confirm the functional suitability of the component. Such tests should be performed under the most severe service conditions envisaged in the appropriate standards for the gas appliances and/or equipment. |
