4.4 Test Setup
The railing assembly was installed and tested as a single railing section by directly securing
(surface-mounting) the base of the aluminum post mounts to a rigid steel test frame. For the
wood posts the railing assembly was installed and tested as a single railing section by directly
securing the 4x4 treated wood posts (Southern Pine) to a rigid test frame, which rigidly restrained
the rail system. The 4x4 treated wood posts were included only to facilitate anchorage of the
test specimen and were not tested components. The railing was assembled by an Intertek-ATI
technician. Transducers mounted to an independent reference frame were located to record
movement of reference points on the railing system components (ends and mid-point) to
determine net component deflections. See photographs in Appendix B for test setups.
4.5 Test Procedure
Testing and evaluation was performed in accordance with Section 4.2.1 of ICC-ES
™
AC273. The
test specimen was inspected prior to testing to verify size and general condition of the materials,
assembly, and installation. No potentially compromising defects were observed.
One specimen was used for all load tests which were performed in the order reported.
Each design load test was performed using the following procedure:
1. Zeroed transducers and load cell at zero load;
2. Increased load to specified test load in no less than ten seconds; and
3. Held test load for no less than one minute.
4.6 Test Results
Unless otherwise noted, all loads and displacement measurements were normal to the rail
(horizontal). The test results apply only to the railing assembly between supports and anchorage
to the support.
Key to Test Results Tables:
Load Level: Target test load
Test Load: Actual applied load at the designated load level (target). Where more than
one value is reported, the test load was the range (min. - max.) that was held during the
time indicated in the test.
Elapsed Time (E.T.): The amount of time into the test with zero established at the
beginning of the loading procedure. Where more than one value is reported, the time
was the range (start-end) that the designated load level was reached and sustained.
