AC273 - Section 4.2.7
3.1 General
The purpose of this testing was to simulate a 90 degree bracket loading condition, which
addresses a situation when the guardrail system is to be installed with the top rails in a corner
condition.
3.2 Test Specimens
Short sections of the top rail were attached in accordance with Fortress Railing Products’
installation instructions to short sections of posts. Specimens were assembled by an Intertek-ATI
technician. Rail brackets were secured to the post and to the rail as described in Section 4.4
Fastening Schedule.
3.3 Test Setup
The testing machine was fitted with the post sections at the top and bottom to accommodate
anchorage of the rail and brackets. The top post section was attached to the test machine’s
crosshead with a swivel mechanism, and the bottom post section was attached rigidly to the base
of the test machine. Two specimens were tested in this manner with each of the two specimens
including two connections for a total of four connections. See photograph in Appendix B for test
setup.
3.4 Test Procedure
Testing was performed in accordance with ASTM D 1761 and by using a computer-monitored and
-controlled SATEC Unidrive, Model MII 50 UD Universal Testing Machine. Tests were run at a
crosshead speed of 0.05 in/min, and each specimen was tested in tension to its ultimate load
capacity. Testing was conducted on October 22, 2015.
