All this says about leeching is:

> 4.8 Specification and determination of the release of toxic elements

> The specification and determination of the release of toxic elements must comply with the requirements specified in the national laws of the country.

Most of the other requirements are about the mechanical properties of the enamel.

There's also this:

> 4.32 Determination and control of Lead and Cadmium release for hot water tanks

But that doesn't apply to cookware.

There's nothing here about requirements for the composition of the enamel or the making public thereof. And what constitutes a "toxic element" (and presumably the dosage) is left to the laws of each country. Most of these countries would consider stainless steel to meet their leeching requirements as well. So we're back to square one. There's no way to tell what the enamel is leeching. You just have an assurance that it's considered safe.
