ASTM E84 vs EN 13501-1: Fire Ratings Explained for Hotel Wall Panels

By ENIS Editorial Team · 2026-09-28 · ~5 min read

Every commercial hotel wall panel must meet fire codes, but the way those codes are written and tested varies wildly between the US, EU, and Middle East. This guide is for the procurement manager who needs to actually pass a fire marshal review without resubmitting three times.

You sourced a beautiful wall panel. The price is right, the lead time is 7 days, the supplier is responsive. Then your local fire marshal rejects the permit application because the panel test report is missing, or the test was done by an unaccredited lab, or the rating class does not match the building code for the wall location. This happens more often than it should.

Why two standards exist

ASTM E84 is the US standard (also referenced across the Middle East and parts of Southeast Asia). EN 13501-1 is the European standard (also adopted in the UAE via UAE Fire and Life Safety Code, in Saudi Arabia, and many African countries). Both test how a material behaves in a fire scenario, but they use different test rigs, different flame sources, and different reporting conventions.

For projects that ship globally, you want a panel with both ratings. The good news: a well-formulated SPC or WPC panel passes both. The better news: the same SGS test report covers both because SGS runs the panels through both protocols.

How ASTM E84 works

ASTM E84 is the "Steiner tunnel test". A 7.3 m long panel sample is mounted as the ceiling of a tunnel. A gas burner at one end applies 90 kW of flame for 10 minutes. Two numbers come out:

• Flame Spread Index (FSI) — how far flames travel along the panel. Lower is better.
• Smoke Developed Index (SDI) — how much smoke the panel generates. Lower is better.

Class A is FSI 0-25, SDI 0-450. Class B is FSI 26-75. Class C is FSI 76-200. For commercial hospitality, you almost always need Class A.

How EN 13501-1 works

EN 13501-1 has seven classes (A1, A2-s1,d0, B-s1,d0, C-s1,d0, D-s1,d0, E, F). The European system combines three separate tests: a single-burning-item test (EN 13823), a small-flame test (EN 11925-2), and a calorific content test. The classification string includes smoke production (s1, s2, s3 — s1 is lowest) and burning droplets (d0, d1, d2 — d0 is no droplets).

For hotel wall panels you typically need B-s1,d0 or better. The "s1,d0" part is what matters: minimal smoke and no flaming droplets that could spread fire downward.

What major hotel brands require

Most international hotel brands specify Class A / B-s1,d0 as the minimum across guest-facing areas. Marriott, Hilton, IHG, Accor, and Hyatt all accept panels with both ratings. Budget brands (Hampton, Holiday Inn Express) sometimes accept Class B in service areas to cut cost.

For Middle East projects specifically, the UAE Fire and Life Safety Code and Saudi Arabia's SBC 801 or 802 require both ratings plus an Arabic translation of the test report for permit submission. Plan 4-6 weeks for the translation and certification process.

Documentation for permit submission

For a permit application, the fire marshal typically wants:

1. Third-party test report from an accredited lab (SGS, Intertek, TUV, UL). Self-declared ratings are not accepted.
2. Test report dated within the last 24 months — older reports require re-testing or a "no material change" attestation.
3. Product identification — SKU codes, batch numbers, manufacturer name and address.
4. Installation method statement — what substrate, what adhesive, what gap spacing.
5. For EN 13501-1 in Middle East — Arabic translation attested by a certified translator.

Common documentation mistakes

Three recurring issues that delay permits:

1. Test report from a non-accredited lab. Some Chinese factories use local labs that are not ILAC-accredited. Fire marshals reject these. Always request ILAC-MRA accreditation evidence.
2. Generic test report, not product-specific. A report that says "SPC wall panels, generic" without naming the actual SKU is insufficient. Request a report that names the specific SKU.
3. Report older than 24 months. If the panel formulation has not changed, the report is still valid but you may need a written statement from the factory confirming formulation continuity.

ENIS ships every batch with a current SGS test report naming the exact SKU. Request the report with your quote and you will have permit-ready documentation from day one.
