- 1. 2. 1 Breakawa Friction The breakaway friction was measured with the unit extending and retracting.
The measurements were made at mid position and approximately 1/2 inch away from the fully retracted and fully extended position.
1.2.2 Acceleration A constant load was applied to the snubber and the time required for the unit to travel 1 inch was recorded.
The test was made with tension and compression loads.

to approximately mid-position of travel.
A linear motion transducer was installed to measure unit travel or displacement.
A load cell was in line with the unit centerline to measure axial load.
Refer to set-up in Photograph 4.
The displacement and axial load were monitored on an oscilloscope with the displacement on the vertical axis and the load on the horizontal axis.
Refer to the photographs on pages 11 thru 14, The input motion was a displacement that varied as a sine wave which resulted in a load being developed in both tension and compression.
Rated load was applied for 10 seconds at each of the seven frequency steps.
Results The unit met the requirements.

sub)ected to the breakaway friction and acceleration test.
3.2 Procedure The PSA 3
snubbers were placed in the Steam Chamber with units of other sizes.
Refer to photograph 5.
The chamber was sealed and a quantity of water was introduced into the chamber.
Heat was applied to the chamber and the temperature was monitored with a thermocouple.
The chamber conditions were ad)usted to 330 F and + 15 psig
{Phase I).
0 The air was vented from the chamber which resulted in the units being 0
sub)ected to "all steam".
The temperature was maintained at 330 F minimum and the pressure was allowed to vary between 0 and 15 psig.
The superheated steam condition was obtained by draining water from the chamber in order to keep the pressure from increasing above 15 psig.
A log was maintained of the temperature and pressure.
Refer to pages 19 and 20.
