Classroom Projection Screen
Testing Procedures
Issued: May 2, 2008
Purpose
The purpose of the following procedure is to ensure that projection screens in classroom spaces at The
Ohio State University are properly secured and safe according to design standards and to maintain the
safety of students, faculty, staff, and the public.
Guidelines
Projection screens are to be tested in a consistent and uniform manner. All testing will be performed on
a pass/fail basis with comments recorded for follow-up repairs. The tests are looking for malfunctions
related to manufacturer defects and/or improper installation that will not allow the support structure to
withstand the dynamic load of the projection screen (e.g. the use of bolts not long enough to securely
hold the screen backer board to the substrate, screens anchored directly to drywall without a backer
board, etc.). Screens should be mounted consistently based upon wall and ceiling materials.
Each testing group shall consist of contractors and a Facilities Operations and Development (FOD)
representative. Contractors must be observed by the FOD representative while performing the tests. The
FOD representative is to document the performance of each projection screen on the FOD Projection
Screen Inspection Form (example, page 3). The FOD representative is to serve as an observer/recorder
and is not to partake in the actual testing of the projection screens. Contractors are responsible for
providing all equipment, tools, etc. to perform the task with the exception of the 50 pound testing device.
Note: The contractor that performs the testing will not be permitted to make the follow-up repairs.

Testing Procedures
1. Visual Test
a)
b)
c)
d)
Proper installation of the backer board to the substrate
Proper mounting hardware
Tightness of the hardware
Defects
2. Weight Test
a) 50 lbs. testing device, provided by FOD, is to hang on each screen support
at the screen-hardware interface.
b) Apply same load whether bracket is metal or plastic.
c) A ladder or foot stool may be necessary for placement of the testing
device.
d) Inspect backer board and brackets for tightness.
Weight Test
3. Operation Test
a) Perform procedures (1c) and (1d)
simultaneously with steps (3b), (3c) and (3d).
b) Operate the screen by pulling the screen
straight down until reaching the fully
extended position and then returning to
storage position.
c) Operate the screen by pulling it down at an
angle of approximately 45 degrees until
reaching the fully extended position and then
returning to storage position.
d) If an electric screen, operate the screen from
the remote switch location, reaching the fully
extended position and then returning to the
storage position.
Operation Test: Step 3b
Operation Test: Step 3c
4. In the event a screen fails the procedure and a repair/replacement is needed:
a) Remove the projection screen and place it in a storage area designated by the FOD representative.
b) Mount a notification sign provided by FOD in the vicinity of the teacher station.
c) FOD representative is to contact the Office of Information Technology (OIT) immediately at 247-4357
with the building and room location so that temporary teaching accommodations can be made.
d) FOD representative is to make note of the failure for future repairs.
