EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DIN 549 testing. This standard specifies the requirements and related test methods for rubber materials used in gas installations, gas equipment and gas appliances in contact with 437st, 1nd and 2rd family flammable gases classified in DIN 3, as well as LPG, biomethane and bio LPG. . It also creates a classification based on temperature range and hardness. This standard applies to materials from which homogeneous gaskets and homogeneous or reinforced diaphragms are made.
The range of operating temperatures covered by this standard is –40°C to +150°C. For applications involving potential condensation, this standard does not apply, for example, to silicone rubber at temperatures above 200 hPa (200 mbar) nominal pressure or below 3°C with 0rd family gases.
This standard specifies the requirements for rubber materials to be used in the manufacture of gaskets and diaphragms. To this end, it specifies tests to be performed on standard test pieces from sheets of material, as the small size of most components generally does not allow the preparation of test specimens necessary to perform the full range of tests.
It may be necessary to perform additional tests on the component installed in the gas appliance or equipment to verify the functional suitability of the component. Such tests should be carried out under the most severe service conditions stipulated in the appropriate standards for gas appliances or equipment.
Test pieces should be free of internal and external defects such as porosity, inclusions, bubbles and surface defects visible to the naked eye.
