EN 13964 Explained: What a Suspended Metal Ceiling Must Meet for CE Marking

EN 13964 is the European harmonised standard for suspended ceilings. To place a suspended ceiling product on the EU market with a CE mark, the manufacturer must issue a Declaration of Performance (DoP) based on it. For metal ceilings, the declared values that matter most on a project are reaction to fire, the deflection class of the grid, and the durability (exposure) class.

What EN 13964 Covers (and What It Doesn’t)

EN 13964:2014, Suspended ceilings — Requirements and test methods, applies to interior suspended ceilings in general buildings. It covers four kinds of product:

• Membranes: the visible ceiling panels, tiles, planks, baffles ou grilles.
• Individual substructure components: main runners, cross tees, carriers, hangers, perimeter trims and connectors.
• Substructure kits: a complete grid sold as a set.
• Suspended ceiling kits: membrane and substructure sold together as one system.

The standard does não cover, among others:

• ceilings used outdoors, such as canopies, petrol stations, open car parks and tunnels;
• heavy-duty ceilings that people can walk on;
• ceilings that must resist water penetration;
• stretched ceilings, which have their own standard (EN 14716).

This matters for aluminum products. An exterior soffit or a gas-station canopy may use the same panels as an interior ceiling, but it falls outside EN 13964 and needs to be specified for wind load and weather separately.

CE Marking and the Declaration of Performance

Under the EU Construction Products Regulation, a product covered by a harmonised standard needs a DoP before it can carry the CE mark. The DoP is the manufacturer’s legal statement of how the product performs. The CE mark only says that a DoP exists and that the product matches it.

A valid DoP for a suspended ceiling product includes:

1. a unique identification code for the product type;
2. its intended use (for example, “suspended ceiling membrane for interior use”);
3. the manufacturer’s name and address;
4. the AVCP system for each characteristic (see below);
5. the harmonised standard: EN 13964:2014;
6. the notified body, where one was involved, with its four-digit number;
7. the declared performance for each essential characteristic;
8. a signature, place and date.

What the AVCP system numbers mean

AVCP stands for Assessment and Verification of Constancy of Performance. It tells you how much independent checking stands behind each declared value:

A DoP that lists System 1 or 3 should also name a notified body. If it doesn’t, ask why.

What changed with the new CPR

The new Construction Products Regulation, (EU) 2024/3110, has applied since 8 January 2026. It replaces Regulation (EU) No 305/2011 gradually, product family by product family. Until new harmonised specifications are published for ceilings, EN 13964:2014 remains the reference, and DoPs issued under it remain the basis for CE marking. When ceilings move to the new framework, the DoP and the declaration of conformity will be combined into a single document (DoP&C). The transition runs until 2040 at the latest.

The Essential Characteristics a Metal Ceiling Declares

“NPD” (No Performance Determined) is allowed for characteristics that are not regulated in the country of use. It is not allowed for characteristics your project actually needs, so check the NPD lines carefully.

Reaction to Fire and Fire Resistance

Reaction to fire is classified under EN 13501-1. Uncoated aluminum is A1 without testing, but coated panels and panels with acoustic fleece need their own test. Fire resistance (EI 30, EI 60) can only be declared for a complete ceiling kit tested as a system. We cover both in detail in our guide to aluminum ceiling fire ratings.

Load-Bearing Capacity and Deflection Classes

EN 13964 tests the grid and its suspension to find how much load it carries before it bends too far between two hangers. The result is expressed as a deflection class:

Class 1 is the most demanding and the usual choice for visible metal ceilings, where a sag of a few millimeters shows clearly along long panel joints. Manufacturers usually publish load tables showing the maximum hanger spacing for a given panel weight at Class 1.

Two practical points:

• The class applies to a stated load, span and hanger spacing. If your panels are heavier or your hangers further apart, the class may no longer hold.
• Light fittings, diffusers and speakers add load. Unless the grid was tested for them, they need their own support.

Durability: Exposure Classes A to D

EN 13964 sorts the environment a ceiling will live in into four exposure classes. Each component is then declared suitable for a class.

Offices, schools and shops are typically class B. Kitchens, changing rooms and spaces with condensation need class C. Swimming pools, chlorinated or coastal environments and industrial areas need class D, and usually a specific corrosion assessment as well. See our guide to specifying aluminum ceilings for coastal and high-humidity climates and our U-baffle ceiling for natatoriums.

For metal ceilings, the weak point is rarely the aluminum panel. It is the steel grid and hangers. For example, one major European grid maker protects its standard class B grid with 100 g/m² of zinc, and adds thicker zinc plus a paint layer for classes C and D. Ask your supplier what protects the steel parts for your class. The finish on the panels matters too: compare powder coating and PVDF before you choose.

How to Write EN 13964 into a Specification

A clear specification avoids arguments later. A typical clause for a metal ceiling in an office corridor might read:

Suspended metal ceiling kit to EN 13964:2014, CE marked with a Declaration of Performance. Reaction to fire: A2-s1,d0 or better to EN 13501-1. Deflection: Class 1 at the specified panel weight and hanger spacing. Exposure class: B. Release of asbestos: no content. Sound absorption: αw ≥ 0.70 for perforated panels with acoustic fleece.

Adjust the exposure class and acoustic value to the space. For a pool hall, for example, change the exposure class to D. For public-sector projects, see also our notes on government building ceiling specifications.

Buying from China: A 7-Point CE Document Check

Many European projects now source metal ceilings from China. Before you approve a submittal, check:

1. The DoP exists and names EN 13964:2014. A general “CE certificate” is not a DoP.
2. The product in the DoP matches what you are buying. Panel type, thickness, coating and backing must be the same.
3. A notified body is named where System 1 or 3 applies, with a four-digit number you can look up in the EU’s NANDO database.
4. Test reports behind the DoP are available, especially for reaction to fire.
5. No NPD on characteristics your project needs.
6. The CE label is on the product or packaging, with the year, the product code and the DoP reference.
7. The importer knows its duties. Under EU rules, the importer must check that the CE marking and documents are in order before placing the product on the market.

For the commercial side of sourcing, see our step-by-step guide on how to import aluminum ceilings from China.

If your supplier quotes Chinese standards

Chinese factories often describe their steel grid against GB/T 11981, the national standard for steel furring. Its current edition, GB/T 11981-2024, has applied since 1 May 2025. Test results under GB/T 11981 are useful evidence of quality, but they are not EN 13964 classes. In particular, Chinese deflection limits are expressed differently from EN 13964 Class 1 (L/500 and no more than 4 mm). Ask the supplier to state the EN 13964 deflection class directly, or to test the grid to EN 13964 clause 5.

For corrosion, ask for the double-sided zinc coating mass in g/m², whether the grid is hot-dip galvanized or electro-galvanized, and any neutral salt spray report. Hot-dip galvanized and aluminium-zinc coated steel generally resist corrosion better than electro-galvanized steel. These figures help you judge which EN 13964 exposure class the grid can realistically meet.

Please tell us your target market at the inquiry stage.

FAQ

Is CE marking mandatory for suspended ceilings in the EU? Yes, for products covered by EN 13964 that are placed on the EU market. The manufacturer must draw up a DoP and affix the CE mark.

What is the difference between Class 1 and Class 2 deflection? Class 1 limits sag to L/500 and no more than 4 mm between suspension points. Class 2 allows L/300. Class 1 is the usual choice for visible metal ceilings.

Which exposure class do I need for a swimming pool? Usually class D. Chlorine and condensation attack steel grid components first, so check their protection, not just the aluminum panels.

Does EN 13964 apply to outdoor aluminum soffits? No. External ceilings such as canopies, petrol stations and car parks are outside its scope and need a separate design for wind and weather.

What does NPD mean on a Declaration of Performance? No Performance Determined. The manufacturer has not declared a value for that characteristic. It is acceptable only where your project has no requirement for it.

Does the new Construction Products Regulation change EN 13964? Not yet. EN 13964:2014 remains the reference until new harmonised specifications for ceilings are published. The main future change is a combined Declaration of Performance and Conformity.
