Send an envelope inquiryCheck what to confirm before you brief usHow certificates are handled on this site
Most certification questions are answered in the inquiry itself: ask which certificates apply to the system and scope you are ordering, and request copies for the specific order. That keeps the answer tied to your project rather than to a generic claim.
One exception is noted on the envelope pages, where a single product news item is quoted with its date and its company-news attribution. That news item is not repeated here as a site-wide certification claim, and it is not extended to any other product or system.
