Scope:-
This Tata motors specification covers the requirements of shower test to be conducted on all Tata vehicles with enclosed compartments for carriage of passengers or goods
Test facility:- The nozzles used for top & sides shall be of full cone and solid type having a spray angle
of 60 degrees & capable of spray pattern for maximum surface
Pitch of theses nozzles 400 mm in both direction
Two nozzles shall be of full cone & solid type having a spray angle of 120 degrees, theses nozzles shall be placed along the center line of vehicle – first nozzle placed 500mm behind front axle & second one 1000 mm from first nozzle
Group A Group B
