7. testing method
7.1 testing method for materials
7.1.1 the measuration for the rubber drawing and extention and the rate of snap and elongation.
according to the test of GB 527,GB/T 528,the result should fit for the request of form 1.
7.1.2 rubber rigidity testing
according to the test of GB/T531,the result should fit for the request form 1.
7.1.3 rubber hot air aging testing
according to the test of GB 3512,the result should be the request form 2.
7.1.4 adhere internsity for sulfuration rnbber and the polyamile cloth testing
accorging to GB/T 532 testing,the result should be request form 1.
7.2 products size warp and distortion measurment
7.2.1 size warp measurment
when ballonet charges and waters,and the pressure reaches the working pressure,
measured by the tapeline of diagragh 1 mm,the warp should be request form 4.
7.2.2 elasticity testing
when ballonet charges and waters ,and pressure reaches the used pressure on the
form 3 is 1.2 times ,measured by the tapeline of diagragh 1mm.the perimeter is c,the formula
is as followings :
d=c/-D'..............................................................(1)
d diameter elasticity
c perimeter
D' actual diameter under working pressure
7.3 testing the working pressure by demolish
7.3.1 for testing
diameter is 0.6m,length is >1.8m,material,structure ,technics are the same with
products ballonet .
Also can use other ballonet as testing ,but the length must >3 times than the diameter.
material,structure,technics are the same with the products ballonet.
7.3.2 testing temperature
-10-40 degrees
7.3.3 testing apparatus
1.5 grades pressure gauge
7.3.4 testing method air carrying charging demolish
7.3.5 demolish pressure average

the formula is :
P=p1+p2+p3/3............................................................(2)
P1,p2,p3 are the first,second ,third ballonet demolish pressure,Mpa.
7.3.5.2 P should be=or >4.5 times than the pressure on the form 3
7.3.5.3 the testing for the ballonet pressure

P is demolish testing pressure average
D1 is ballonet body diameter
D is ballonet dianmeter
n is safety modulus
7.4 working pressure testing
after charging ,and pressure reaches the 1.5 Pe,keeping 10 min,pressure falling
should <2%
7.5 air density testingwhen charging ,and pressure reaches the Pe,after 1h should reach for the 6.3.4.
7.6 others
testing apparatus,tools,equipments should be proved regular.the precision should be
the request for the objects tested.
