Acceptance specifications
The index applies its own acceptance specification by compound class. Every threshold is published with its reasoning and its observed failure rate. None of them is a regulatory limit and none of them is a safety threshold — a specification is a line this site drew, and these pages exist so that any PASS or FAIL chip anywhere on the site can be traced back to the decision behind it.
