I am searching for test on small parts for children under 3 years. I found the definition for the US (see below) but not for the EU. Page 87 of the Explanatory Guidance Document to Toy Safety Directive 2009/48/EC mentions:
This means that like the toys under point 4 (d), the packaging needs to pass the small parts test cylinder test 8.2 in EN 71-1:2011.
I found this page that mentions "EN 71-1:2011", but has no link.
How can I find the EU definition of a small part for children under 3?
For the US: I found this page from the US Consumer Product Safety Commission:
A small part is any object that fits completely into a specially designed test cylinder 2.25 inches long by 1.25 inches wide that approximates the size of the fully expanded throat of a child under three years old.
If a small part fits completely into the cylinder, and the toy or product from which it came is intended for use by children under three, the toy or product is banned because the small part presents a choking hazard.
