Testing & certification

Every document behind our products is published here in full. Open any page to read the certificate itself — the issuing laboratory, the report number, and the date it was signed.

We also state what each document does not cover. A test proves one specific thing about one specific sample, and we would rather you read the limits from us than assume them.
