Does anyone can help me solve these questions?

1. What is the limitation for tin migration?
2. What is the prohibited compounds for tin?

Hope someone can help me solved these. Thank you.

For Great Britain, the limitation of tin cannot exceed 200mg/kg. (1992 No. 496)

It seem like only lead solders are prohibited under Sec 189.240 and EC No. 242/2004. Is it still have any others compounds or substances that prohibited in tin?

I have a question. Are tins such as those used for packing baked beans actually made from tin. If so, are they coated or not?

The cans are steel with a thin coating of tin on the inside, tin is resistant to corrosion but very expensive (and heavy!). I think some drinks cans are aluminium and I presume these aren't coated with tin as Aluminium is fairly corrosion resistant itself.

Dear Simon / All,

Interesting thread.

Hence the phrase "tin plate" = Thin sheet iron or steel coated with tin to prevent rusting, used especially to make cans and pots.
Try this - http://en.wikipedia.org/wiki/Tin_can

The changes in can design have a very complex history, fascinating timeline here -

The question of "tin can" vs aluminium can also looks interesting. Seems that, although there are considerable geographical variations, typically tinplate wins for food and aluminium for beverages. I guess this is due to a combination of parameters, eg cost, recycling, quality, whether the last one ever dominates, no idea. Any can people around ??
