Thus, Royal Decree 473/1988, of March 30, transposed Directive 76/767 / EEC on pressure equipment; Royal Decree 1495/1991, of October 11 and Royal Decree 2486/1994, of December 23, Directives 87/404 / CEE, 90/488 / CEE and 93/465 / CE on simple pressure vessels; Royal Decree 2549/1994, of December 29, Directives 75/324 / EEC and 94/1 / EEC on aerosol generators; Royal Decree 769/1999, of May 7, Directive 97/23 / CE, relating to pressure equipment, establishing new criteria for the design, manufacture and evaluation of conformity and Royal Decree 222/2001, of 2 March, together with Order CTE / 2723/2002, of October 28 and Royal Decree 2097/2004, of October 22, Directives 1999/36 / EC, 2001/2 / EC and 2002/50 / EC, on transportable pressure equipment
