Fire Reaction Certificate
B – s1, d0

Our profiles and wall protectors are classified with Euroclass B-s1,d0 according to the UNE-EN 13501-1 standard, the most demanding European standard for construction materials in buildings for public use.

Euroclass Nomenclature

What does each letter on the certificate mean?

The B-s1,d0 classification groups three independent parameters that together define the complete behavior of the material in fire.

B

Fire behavior

Combustible material with a very limited contribution to fire. Class B is the second-best Euroclass, immediately below Class A (non-combustible), and guarantees that the material barely propagates the flame..

s1

Smoke production

Low smoke production and minimal opacity. The s1 classification is the most favorable: the smoke generated during combustion is scarce and not very dense, which improves visibility and facilitates evacuation of the building.

d0

Inflamed drops

No falling flaming droplets or particles during combustion. Class d0 is the best possible in this parameter, eliminating the risk of the material contributing to the spread of fire to other areas..

Importance of the standard

Why the B-s1,d0 classification makes a difference

  • Mandatory in hospitals and healthcare centers

    The CTE (Technical Building Code) requires materials with a high fire reaction classification in hospitalization areas, operating rooms and evacuation routes.

  • Improves evacuation safety

    With low smoke production (s1) and no flaming droplets (d0), escape routes remain clearer and safer for longer.

  • Requirement in public tenders and bids

    Many technical specifications for public buildings, senior residences, and hotels expressly require class B-s1,d0 or higher.

  • Respaldo técnico y legal verificable

    El certificado emitido por AFITI-LICOF es un documento oficial que acredita el cumplimiento normativo y protege a prescriptores, instaladores y propietarios.

Certification process

How is the B-s1,d0 certificate obtained?

The Euroclass classification requires a rigorous technical process carried out by laboratories accredited and recognized by the relevant authorities.

1

Sample selection

The manufacturer prepares representative samples of the final product, including all color and substrate variants, as specified in the field of application.

2

Standardized tests

The accredited laboratory performs the tests according to the UNE-EN 13501-1 standard, which includes the SBI (Single Burning Item) test and other complementary tests.

3

Technical Evaluation

Laboratory technicians analyze the data obtained in the tests: heat release rate, smoke production, opacity, and presence of flaming droplets.

4

Classification Report

The laboratory issues the Fire Reaction Classification Report, an official document that certifies the Euroclass obtained and its field of application.

Our official laboratory

Certificate obtained at AFITI-LICOF

At Ziko Europa S.A., we obtained our fire reaction classification from the AFITI-LICOF laboratory, the official fire testing laboratory of the Spanish Ministry of Industry, founded in 1975.

The report certifies the B-s1,d0 classification for our entire range of PVC wall protectors in accordance with the UNE-EN 13501-1:2019 standard, including colour and substrate variants as detailed in the scope of application of test EXAP No. 4011T20.

The classification is valid for all available colors and for plasterboard substrates with a density equal to or greater than 523.5 kg/m³ with Euroclass A1 or A2-s1,d0, as indicated in the technical report.

Regulatory framework

La norma UNE-EN 13501-1

The European harmonised reaction to fire classification system establishes seven classes (A1, A2, B, C, D, E, F) and additional criteria for smoke and flaming droplets.

Euroclass fire reaction classes

The standard defines a scale of seven main classes:

  • A1 / A2 — Non-combustible materials
  • B — Very limited contribution to the fire ✓ Zikonyl
  • C — Limited contribution to fire
  • D / E / F — Lower classes of higher risk

Additional parameters evaluated

  • s0 / s1 / s2 / s3 — Smoke production (s1 = minimum) ✓ Zikonyl
  • d0 / d1 / d2 — Inflamed drops (d0 = none) ✓ Zikonyl
  • Evaluated with the SBI assays (EN 13823) y Epiradiateur (EN ISO 11925-2)
  • Valid results without the need for further testing for color variants
Where it is required

Sectors that require classification B-s1,d0

Our products are designed for environments where fire safety is non-negotiable..

Hospitals and clinics

Hospitalization areas, operating rooms, emergency rooms and corridors where regulations require maximum fire protection.

Nursing homes

Centers where residents may have reduced mobility, making fire prevention and evacuation critical.

Educational centers

Schools, universities, and teaching facilities where large groups of people gather.

Hotels and accommodations

Hotel establishments subject to strict fire protection regulations in all common areas and rooms.

Public buildings

Administrative offices, courts, museums, and any publicly owned or used building with high capacity.

Transport and infrastructure

Metros, airports, stations and high traffic areas where fire regulations are especially rigorous.
