I wonder how many vans have their chains adjusted correctly to comply with the regs.Most I see on the road have their chains almost dragging on the bitumen,in fact you can see them dangling when travelling behind.By the same token I wonder if they would really stop the draw bar from hitting the deck.(I don't really want to find out either).

Vehicle Standards Bulletin VSB1 details the legal requirements for trailers up to 4.5 tonnes (ie all ADR light category trailers)
The standard is not very exciting reading BUT is the legal requirement for construction.
John has provided the other info above.

They are certainly on most caravans, Dibs - definitely on mine ... should be on all caravans.
This is what the 'rating stamp' looks like -

Rule of thumb or requirement for chain lenths on drawbar of Van ??...
If you are talking about the safety chains, there is no rule of thumb (like there is for ball weights) for the chain lengths. Different manufacturers supply different lengths.

Really there should be variations in chain lengths because they should be matched to the LEVEL height of the van.
Your towbar coupling should be matched to the level height of your van as well. Your van should couple at a level ride, not nose up or nose down.
If your van's drawbar is 'X' height when level then the chains need to be shorter than that to hold it up from the ground.
All chain mounting points on tow bars are BELOW the coupling (ball) and it is the variations in towbar design where the chains attach to, that can make your chains appear too long or short.
Perfect for my towbar might be too short or too long for yours.
