A. Cross Sectional Vertical Height - The horizontal member of each guard is
required to have a cross sectional vertical height of at least 100 mm at any
point across the guard width.
B. Strength and Energy Absorption - Each guard is required to comply with
the strength requirements at each test location and the energy absorption
requirements at either test location P3 when tested under the procedures of
S6 of S223.
Guard Strength
The guard must resist the following force levels without deflecting by more
than 125 mm.
(1) A force of 50,000 N at test location P1 on either the left or right side of
the guard.
(2) A force of 50,000 N at test location P2.
(3) A force of 100,000 N at test location P3 on either the left or the right
