TB/T 2783-2017Exhaust emission tests for diesel engines of motive power units (English PDF)

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).
