Chevy response to LATCH anchor question.
A friend referred me to this forum for help deciphering an answer I got from Chevy when I asked what my LATCH anchors were tested to, as the manual to my Britax Marathon states not to use the LATCH attachments with a child weighing more than 48 lbs, unless the vehicle manufacturer says they are tested higher. The answer that Chevy gave me is very thourough, but not being an engineer I don't really understand it. Can someone help translate this?
Thank you,

Regarding the weight that was used to test the LATCH bar in your 2001 Chevrolet
Venture, please note below:
Each lower anchorage would be tested separately by applying a force of 5,300 N
(1,190 pounds) to the anchorage in the forward horizontal direction parallel to
the vehicle's longitudinal axis. The force would be applied by means of a belt
strap that is fitted at one end with hardware for applying the force and at the
other end with hardware for attaching to an anchorage or connector.
The force would then be applied so that the 5,300 N (1,190 pounds) force is
attained within 30 seconds, with an onset rate not exceeding 135,000 N (30,337
pounds) per second, and would be maintained at the 5,300 N (1,190 pounds) level
for at least 10 seconds. When tested in this manner, no portion of any
component attaching to the lower anchorage bars shall move forward more than 125
mm (5 inches), and that there shall be no complete separation of any anchorage
component.
