ANSI/ASSE Z359.12-2009 & CAN/CSA Z259.12-2011 Requirements for Carabiners:
These American & Canadian National Standards became effective in November 2009 & November 2011 respectively. Both standards require a minimum 'all round' gate strength (minor axis, gate face and gate side load strengths) to meet or exceed 3,600 lbs (16 kN). The carabiner gate must be marked with this load rating & the body with the minor axis load rating.
