Test procedures For Connecting And Hose Tubes Of Vacuum Cleaners
Testing Equipment:
The deivce, as shown in Figure 29, cosists of a screw press with
the support covered by a piece of test carper, in accordance with
7.2.1.3.2. The force of the screw press is transmitted by a spring
to a test plate of polished steel on a cylindrical bearing, the
axis of which is perpendicular to that of the test pbject.
The force applied is indicated on a load indicator and yje reduced
cross-sectional dimension is measured by a vernier or digital
calliper.
