What Is the IMO FTP Code for Marine Interior Materials?

Confused by marine certifications? If your interior panels fail fire tests, shipyards will reject your entire project. I will show you exactly what the IMO FTP Code means.

The IMO FTP Code (International Code for Application of Fire Test Procedures) is the mandatory testing standard under SOLAS. It provides the specific technical requirements, laboratory testing procedures, and certification criteria for all marine interior materials, ensuring they do not fuel fires or emit toxic smoke on ships.

Passing these tests is the only way to sell your panels to European and American shipyards. Let us look closely at how this code affects your daily purchasing decisions.

What does IMO FTP Code stand for in marine fire testing?

Need the right certificate but do not know the exact term? Buying panels without knowing the FTP abbreviation wastes time. Here is the exact definition you need to know.

The IMO FTP Code stands for the International Maritime Organization's International Code for Application of Fire Test Procedures. It consists of three main components: testing requirements, laboratory accreditation rules, and specific criteria for testing non-combustibility, flammability, and smoke toxicity for marine outfitting products.

Understanding the International Maritime Organization Framework

I remember when a client from Asia sent their marine wall panels to Europe. They had local fire certificates, but the shipyard rejected them. Why? Because they did not understand the IMO framework. The International Maritime Organization (IMO), based in London, sets the global rules for shipping.¹ Under the Safety of Life at Sea (SOLAS) convention, Chapter II-2² demands strict fire safety. The FTP Code is the rulebook that tells laboratories exactly how to test materials.³ Without this code, shipyards would not know if a panel is truly safe for ocean travel.

The Three Main Components of the FTP Code

As I stated earlier, the code has three main components. First, the testing requirements dictate the physical conditions. For example, a furnace must reach exactly 750°C (according to ISO 1182) to test non-combustibility.⁴ The technicians must measure the temperature inside the furnace, on the surface of the specimen, and in the center of the specimen. Second, the code gives the rules for laboratory accreditation. You cannot test materials in your own factory lab. You must use independent testing laboratories recognized by national maritime administrations, like DNV in Norway or Lloyd's Register in the UK. These labs charge around $3,000 to $5,000 USD per test part. Third, it sets the criteria for non-combustibility, flammability, and smoke toxicity. A marine ceiling panel might not burn, but if the PVC film melts and releases deadly gas, it fails the toxicity test. A panel must pass all three criteria to get the final certificate. You cannot pick and choose which rules to follow.

It is clear that you must understand these components to verify your supplier's claims. Now let us look at the exact test parts you must ask your suppliers about.

Which fire test parts does the IMO FTP Code contain for marine panels?

Are you unsure which exact test your panels need? Guessing the wrong test wastes thousands of dollars. Here are the precise test parts required for your marine interior materials.

The IMO FTP Code contains eleven distinct fire test parts. For marine panels, the four critical parts are Part 1 (Non-combustibility), Part 2 (Smoke and toxicity), Part 3 (A, B and F class divisions), and Part 5 (Surface flammability). All four must be passed for complete certification.

Examining Part 1 and Part 3 for Marine Core Materials

When I worked at the marine outfitting factory, we focused heavily on the core materials of our panels. To pass Part 1 (Non-combustibility), materials like rockwool must endure a furnace at 750°C for 30 minutes⁵. During this time, the furnace temperature must not rise by more than 30°C. Also, the sample must not lose more than 50% of its mass. This is according to the exact text in the 2010 FTP Code. Next is Part 3, which tests "A", "B" and "F" class divisions. Your marine fire doors and wall panels usually fall here. For a B-15 class marine panel, the unexposed side temperature must not rise more than 140°C above the starting temperature during a 15-minute standard fire test.⁶ If you are selling to high-end shipyards, they check these Part 3 certificates before anything else.

Analyzing Part 2 and Part 5 for Surface Finishes

After checking the core, you must look at the surface. You cannot put normal PVC on a marine panel. Part 5 (Surface flammability) checks how fast flames spread across your decorative finish. The lab measures the critical heat flux at extinguishment, which must be at least 20 kW/m2 for bulkhead finishes⁷. Part 2 (Smoke and toxicity) measures the deadly gases. For example, carbon monoxide limits are strict; the maximum allowed concentration during a test is 1450 ppm⁸ (parts per million). Hydrogen chloride must stay below 600 ppm, according to IMO resolution MSC.307(88). If your Asian supplier uses cheap glue, the panel will fail Part 2 immediately. I always advise buyers to ask the factory about their glue. All four parts are legally required.

Knowing these parts helps you avoid suppliers who only test half their product. Let us move on to the timeline of these rules so you do not buy outdated materials.

When was the IMO FTP Code adopted and revised?

Holding an outdated certificate? A shipyard will reject your products if your documents use old standards. Here is the timeline to ensure your certificates are completely valid today.

The original IMO FTP Code was adopted in 1996 through Resolution MSC.61(67). The most important revision happened when the 2010 FTP Code was adopted, which entered into force globally on July 1, 2012. You must ensure your current marine materials comply with the updated 2010 regulations.

The Origins in the 1996 IMO FTP Code

History matters in this industry. The first formal, unified document was the 1996 FTP Code, officially adopted on December 5, 1996⁹. Before this time, testing was chaotic. I heard stories from older engineers about how a panel approved in one country was blocked in another. The 1996 Code, created under Resolution MSC.61(67), fixed this problem. It forced all maritime nations to use the exact same test procedures for their ships. It became legally binding on July 1, 1998. This was a massive change for Asian factories exporting to Europe, as they suddenly had to buy new testing machines to match the global standard.

The Transition to the 2010 IMO FTP Code

Technology changed, and fires still happened. The IMO realized they needed stricter rules. They adopted the 2010 FTP Code on December 3, 2010, and it became mandatory on July 1, 2012.¹⁰ This is the version you must care about today. When you ask a supplier for a fire certificate for marine wall panels, check the top right corner of the paper. It must say "2010 FTP Code". The 2010 revision brought tougher smoke toxicity limits and updated test methods for new composite materials. It also improved the rules for testing floor coverings. If a Chinese factory shows you a certificate tested under the 1996 rules, you cannot use it for a new shipbuilding project in the US. The type approval certificates usually last for exactly 5 years before the factory needs to pay for a renewal audit.

Checking the dates on these certificates takes only a few seconds but saves you from massive losses. Next, let us explore why this code is so powerful in the industry.

Why is the IMO FTP Code called the central fire-test framework for marine interior materials?

Confused by the many maritime rules? Tracking multiple standards will ruin your procurement schedule. Here is why the FTP Code is the only framework you truly need.

The IMO FTP Code is the central framework because it directly supports SOLAS Chapter II-2. It unifies scattered regional rules, provides a single global baseline for all maritime classification societies like DNV or ABS, and guarantees consistent safety performance across all international shipbuilding projects.

Direct Support for SOLAS Chapter II-2 Regulations

The easiest way to understand this is to look at the law. The Safety of Life at Sea (SOLAS) convention is the supreme law for global shipping.¹¹ Specifically, SOLAS Chapter II-2 deals with fire protection, fire detection, and fire extinction.¹² But SOLAS only gives the broad goals. It says things like "bulkheads must restrict the spread of fire." It does not tell you exactly how to prove it. That is why the FTP Code is the central framework. It takes the broad SOLAS goals and turns them into exact, measurable laboratory numbers.¹³ It acts as the direct bridge between the law and the factory floor. Without the FTP Code, SOLAS would be impossible to enforce for interior decoration companies.

Unifying Global Maritime Classification Societies

When you buy a marine fire door, you might need a DNV certificate for a European project, or an ABS certificate for an American project. Years ago, this was a nightmare. Now, because the FTP Code is the central framework, all the major classification societies use it as their absolute baseline.¹⁴ Whether you test in a lab in Shanghai or a lab in Hamburg, the engineers follow the exact same manual. This single global baseline saves procurement officers massive amounts of money. If a Chinese wall panel passes the FTP Code Part 3 test, ABS, Lloyd's Register, and DNV will all accept the test data. They will all issue their own certificates based on that one test report. This guarantees consistent safety performance across all international shipbuilding projects, no matter where the ship is built.

This unification makes your job as a buyer much simpler, as you only need to look for one standard. But you still need to know the exact legal resolution number.

Which IMO resolution officially issues the FTP Code?

Staring at complicated certification documents? Missing the exact resolution number can cause surveyors to reject your cargo. Here are the exact resolution numbers you need on your documents.

The 2010 IMO FTP Code was officially issued under the IMO Resolution MSC.307(88). The previous, outdated 1996 version was issued under Resolution MSC.61(67). For your current marine interior outfitting purchases, every valid test report and Type Approval certificate must explicitly reference Resolution MSC.307(88).

The Current Mandate: Resolution MSC.307(88)

I constantly remind my clients to read the fine print on their certificates. The Maritime Safety Committee (MSC) is the highest technical body of the IMO. When they agree on a new rule, they publish a resolution. The current 2010 FTP Code was officially issued by Resolution MSC.307(88).¹⁵ The number 88 means it was the 88th session of the committee. If you are buying marine ceiling panels today, the Type Approval certificate (also called a MED B certificate in Europe) must clearly state that the product was tested according to MSC.307(88). The test report from the laboratory must also print MSC.307(88) on the front cover. If it does not, a European shipyard will not accept your materials, and you will lose your money. I once saw a buyer lose a $50,000 order because of this simple missing number.

The Outdated Mandate: Resolution MSC.61(67)

It is also important to know the old rule so you can spot mistakes. The old 1996 FTP Code was issued under Resolution MSC.61(67). Some smaller, cheaper suppliers in developing countries might still try to show you older certificates from 10 years ago to prove their quality. Do not accept them. While MSC.61(67) was a great standard in the past, it is no longer valid for new ship constructions today¹⁶. You must explicitly demand MSC.307(88) compliance. Most major testing labs charge a re-testing fee of around $4,000 USD if a factory needs to upgrade their old MSC.61(67) certificate to the new standard. It costs money, which is why cheap suppliers try to avoid it and trick buyers.

Now you know exactly what letters and numbers to look for. Finally, let us discuss why you cannot just use normal building materials on a ship.

How does the IMO FTP Code differ from generic land-based fire test standards?

Tempted to buy cheaper construction panels for a ship? Using land-based materials on marine projects leads to inspection failure. Here are the exact differences between the two standards.

The IMO FTP Code tests for the extreme, isolated environment of a ship at sea, requiring stricter smoke toxicity limits, higher non-combustibility thresholds, and marine-specific class division ratings (A, B, F) compared to the standard EN or ASTM land-based building codes which assume easier evacuation paths.

Stricter Smoke Toxicity Limits for Isolated Environments

I often get asked by buyers why they cannot just buy cheap office wall panels in China and put them on a cruise ship. The answer is evacuation. On land, if a building catches fire, you run outside to the street. On a ship in the middle of the ocean, there is no street. You are trapped in an isolated environment. Therefore, the IMO FTP Code has much stricter smoke toxicity limits¹⁷ than land-based standards like EN 13501 (for Europe) or ASTM E84 (for the US). For marine panels, the FTP Code strictly monitors the release of seven specific toxic gases¹⁸, including Carbon Monoxide (CO), Hydrogen Chloride (HCl), and Hydrogen Cyanide (HCN). Land-based standards often focus only on how far the flame spreads and total smoke volume, but they completely ignore the deadly chemical makeup of that smoke.

Higher Thresholds and Marine-Specific Class Ratings

Besides smoke, the heat thresholds and classifications are entirely different. Land-based codes talk about 1-hour or 2-hour firewalls for concrete structures. The marine industry uses specific A, B, and F class division ratings for lightweight steel structures. For example, an A-60 marine bulkhead must prevent flames and smoke passage for 60 minutes, and the unexposed side temperature must not rise more than 140°C on average¹⁹. To achieve this, marine panels often use high-density rockwool, typically 120 kg/m3 or 150 kg/m3. Cheap land-based office panels use 60 kg/m3 rockwool, which fails the IMO non-combustibility thresholds instantly. You might save 30% on the purchase price buying land panels, but you will lose 100% of your money when the marine surveyor rejects them.

Conclusion

Passing the IMO FTP Code is non-negotiable for marine outfitting. By understanding these fire test procedures, you secure high-quality panels and ensure your European shipyard projects pass every safety inspection.
