Safety Standards & Certifications — What to Verify

Published: December 2025

Certifications can be real and still be misleading if the scope doesn’t match the exact model/version you’re buying. For hyperbaric chambers, ask for documents that are traceable and specific — not just logos on a brochure.

FAQ (quick)

What does “certificate scope” mean?

It defines exactly what is covered: the specific model/version, intended use, and sometimes the market/standards. Scope matters more than badges.

What should I request from a seller?

Manuals, maintenance schedule, and traceable certificates tied to the delivered unit (model/version and serial/traceability details).

What’s a common red flag?

Certificates without scope pages, or documentation that doesn’t match the exact model designation you’re buying.

The minimum document pack

User manual + service manual with safety limits and emergency procedures.
Certificate(s) showing model/version scope, notified body (if applicable), and validity dates.
Maintenance schedule, consumables list, and parts/service availability in your region.
Serial/traceability details that tie the paperwork to the delivered unit.

Common red flags

Certificates without scope pages or without the exact model designation.
Claims that mix “component certification” with “device certification”.
Pressure/oxygen specs that change across pages and brochures.
