Evidence
Testing, accreditation & standards
What Aquasign is proven against, and which standards and bodies apply to subsea and topside identification, in plain terms.
In a safety-critical category, the trust question comes before the feature question. This page sets out how our signage is tested and how to place it against the standards your own assurance process works to.
What we test for
Proven where it matters
Anti-fouling performance
The core claim: that the marker keeps shedding marine growth and stays legible over its stated life.
Adhesion & retention
That the marker and its fixing stay bonded to the substrate through the service environment.
UV & environmental stability
Resistance to fade and degradation from splash-zone exposure to deepwater conditions.
Non-toxicity
100% non-toxic materials, with no biocide leaching into the water column.
Legibility at distance
That identification reads on an ROV feed at working distance and angle, not just up close.
Service life
The basis for the 60-year anti-fouling guarantee on the marker.
The standards and bodies that apply
No single standard covers subsea signage from end to end. Buyers assemble the picture from several sources, and a credible supplier can tell you which apply to your application. The bodies worth naming in full include:
- The International Organization for Standardization (ISO), whose standards cover materials, coatings and quality management relevant to subsea equipment.
- The NORSOK standards maintained for the Norwegian continental shelf, widely referenced across the North Sea.
- DNV, for classification and independent verification of subsea equipment and materials.
- The International Maritime Organization (IMO), whose biofouling guidance is increasingly relevant to anti-fouling materials.
- In UK waters, the expectations of the Health and Safety Executive (HSE) and guidance from Offshore Energies UK.
We will tell you, for your specific application, which of these are relevant and how Aquasign is positioned against them. That is a more honest answer than a single badge, and a more defensible one in a design review. Our guide to judging compliance sets out the questions worth asking any supplier.

Do you hold a single accreditation that covers everything?
No supplier honestly can, because no single standard spans subsea signage end to end. We can show how Aquasign is tested and where it sits against the standards relevant to your application.
Can you provide test evidence for a design review?
Yes. We can share the testing position and material data appropriate to your scope so it can be held on file and defended in an integrity review.
Is the material environmentally acceptable?
The system is 100% non-toxic with no biocide leaching, which supports compliance with biofouling and environmental guidance.
