Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces TB/T 2948-1999, Technical specification for rubber air shield
of railway passenger car, and TB/T 3094-2004, Gangway bellows for railway
passenger car.
Compared with TB/T 2948-1999 and TB/T 3094-2004, the major changes of this
Standard are as follows.
-- it adds the passage requirements for wheel chairs and small catering trucks (see
5.7);
-- it adds the technical requirements for the assembly of rubber vestibule diaphragm
(see 6.1.3);
-- it adds the content of pressure-tight vestibule diaphragm for electric multiple units
(see 6.2);
-- it adds the pressure-tight requirements under pressure load (see 6.2.1.16);
-- it adds the content of exterior vestibule diaphragm (see 6.3);
-- it adds the content of iron vestibule diaphragm (see 6.4);
-- it adds the basic structures and compositions of all types of vestibule diaphragm
(see Annex A, Annex B and Annex C).
