In 1995 new DIN standards were published containing gasket factor definitions, gasket testing procedures and requirements as a basis for technical delivery conditions. The gasket factors in DIN 28090 are consistent with those in the design rules for bolted flanged connections laid down in DIN EN 1591. Both standards together are an advanced and reliable tool for strength analysis and tightness assessment for bolted flanged connections. The new DIN standards contain new features in detail: gasket factors are related to tightness classes allowing tightness classification of flanged joints; time and temperature effects are regarded by means of high temperature longterm aging leakage tests; and gasket material degradation due to chemical attack is covered by means of chemical resistance tests. Verification of gasket testing according to the new DIN standards by means of tests on real flanged joints is under way.
