Trailer Hitch Testing 2

[flugelhn]

Can anyone direct me to a source for information on what testing is required to get a custom designed trailer hitch approved for sale to the general public??

Thank you,

Do a search for hitch under Standards and Papers.

I searched here a bit asnd found tasty sounding references to VSB 1, but could not find VSB No.1 itself

Tmoose, if it's of interest here's the VSB 1:

(405kb). Amazingly, it was the first link in Google for +"VSB 1" +trailer (useful stuff usually isn't that high up).

Kinda off topic but brings back memories. I worked for Draw-Tite and we used to hop in the back of a van with a trailer in tow to test sway bar applications. Someone would drive crazily down a dirt road with the guy in back filming

The 10000 pound test used to shake the entire engineering building. I think we only tested two directions here in the US. European tests had an additonal direction (forward I believe)

We used to twist hitches into pretzels if the engineer was careless in his choice of tube sizes. But its amazing how much the hitch could move and still be acceptable.
