IMO certified marine wallcoverings

A wallcovering going into a vessel is not certified as a wallcovering. It is certified as a surface, and the test is not the one a supplier quotes for a building.

Vessel interiors sit under the IMO Fire Test Procedures Code. A material bonded to a bulkhead or a ceiling is tested for surface flammability under Part 5, which measures how readily the surface ignites, how far flame travels across it and how much heat it releases doing so. Smoke and toxicity are tested separately under Part 2, and on a vessel that second test carries as much weight as the first, because in an enclosed interior with a long route to the deck it is smoke that stops people leaving.

The code splits by how a material is held rather than by what it is. Hanging textiles, curtains and free films sit under Part 7. Upholstered furniture sits under Part 8. Bedding under Part 9. A certificate for one part is not a certificate for another, and the part a document names is worth reading before it goes into a submission.

Beyond fire, the conditions are the ones any marine finish has to meet. Humidity that never drops, salt in the air, condensation behind a lining in a cabin that is cold on one side and warm on the other, and cleaning run to a schedule rather than to taste. A wallcovering that holds in a hotel corridor does not automatically hold in a cabin passage.

So the specification is a document question before it is a material question. Which part, which laboratory, which issue date, and whether the certificate covers the substrate the material is actually going onto. We hold the certificates for the ranges below.
