Anyone who puts a building into service assumes responsibility for more than just its function and aesthetics: they assume responsibility for the lives of the people inside it. The Declaration of Conformity for Fire Protection is the legal and technical instrument through which designers, manufacturers, and construction managers document this responsibility to authorities, building owners, and the public. It confirms that the construction products used and the structures built comply with applicable fire safety requirements, making it far more than just a bureaucratic form: it is the backbone of the chain of evidence in preventive fire protection.

Definition and Legal Basis: What Is the Declaration of Conformity for Fire Protection?
The Declaration of Conformity for Fire Protection is a written declaration by the manufacturer or the company responsible for the work stating that a construction product or construction method complies with the requirements of a technical regulation, a general building authority approval (abZ), or a general building authority test certificate (abP). It is enshrined in German building code law and derives from the state building codes of the individual federal states, which in turn are based on the Model Building Code (MBO). The Construction Products Act and the European Construction Products Regulation (EU CPR, Regulation No. 305/2011) form the overarching European legal framework within which the national regulations are situated.
The term “conformity” does not refer to a general statement of quality, but rather to a precise technical statement: The product or structure conforms to the requirements specified in a particular set of regulations or approval document. These requirements may pertain to fire behavior, fire resistance duration, smoke tightness, melting points of insulation materials, or specific installation conditions. The Declaration of Conformity for Fire Protection is thus an integral part of the chain of evidence, which extends from planning through product selection to execution and acceptance.
Legally, the declaration is required by most state building codes as a prerequisite for the use of certain regulated construction products. Anyone who installs a construction product without the required Declaration of Conformity is acting in violation of the law and risks significant liability consequences in the event of damage. The declaration does not necessarily have to be submitted to the building permit authority, but it must be provided upon request and retained for a specified period. In practice, construction managers and fire protection specialists require the declarations to be submitted no later than the time of final inspection, but often as early as when the products are delivered to the construction site.
Distinction from Related Certification Formats: CE Mark, abZ, abP, and ZiE
The system of proof of suitability for use for construction products in Germany is complex and is often confused in practice. A clear distinction between the individual instruments is therefore a prerequisite for the correct handling of the Declaration of Conformity for Fire Protection. The CE marking, which is awarded on the basis of the European Construction Products Regulation, certifies a product’s conformity with a harmonized European standard (hEN). It is not a quality mark in the strict sense, nor is it proof of suitability for a specific application; rather, it is a Declaration of Performance (DoP) regarding essential characteristics. For fire protection requirements, this means: The CE mark certifies classification according to European testing standards, but does not indicate whether the product meets the requirements of German building codes in a specific construction project.
The General Building Authority Approval (abZ), issued by the German Institute for Building Technology (DIBt) in Berlin, is a national certificate of suitability for use for construction products and construction types for which there is no harmonized European standard or for which the harmonized standard does not cover all relevant requirements. In addition to a description of the product, it also contains detailed rules for use, installation instructions, and testing requirements. The General Building Inspection Test Certificate (abP) is a simplified certificate of suitability for use for products with a lower risk potential, issued by a recognized testing body. Finally, the case-by-case approval (ZiE) is a project-specific exception for products or types of construction that do not have either an abZ or an abP, and requires a separate review by the competent authority.
The Declaration of Conformity for Fire Protection serves as the link between these supporting documents and the specific construction product on the construction site. It declares that the delivered and installed product is in fact identical to the product on which the approval, test certificate, or standard was based. Without this declaration, the approval remains an abstract document with no connection to the actual construction process. This connection is fundamental and is often underestimated in practice.
Who issues the Declaration of Conformity for Fire Protection and when?
The obligation to issue the Declaration of Conformity for fire protection generally lies with the manufacturer of the construction product. In doing so, the manufacturer declares that its product meets the requirements of the respective proof of suitability for use. This manufacturer’s declaration must be distinguished from the Declaration of Conformity within the meaning of CE marking, even though the two are similar in content. In the case of construction systems—that is, the combination of multiple products into a functional unit such as a fire-rated wall or a pipe enclosure system—the responsibility for the Declaration of Conformity lies with the contractor that manufactures and installs the construction system.
In practice, this means: A manufacturer of fire-rated panels issues a declaration of conformity for its panels. The drywall contractor who assembles these panels into a classified partition wall issues a separate declaration of conformity for the completed construction. Both declarations are separate documents with different subjects of reference. As part of project supervision, the fire protection planner or fire protection specialist verifies whether both declarations are available and whether the information provided therein corresponds to the actual installation.
The timing of issuance is also regulated: The declaration of conformity must be available before the product is used or, at the latest, upon completion of the construction. Although retroactive issuance is formally possible, it is problematic under building code regulations because it can no longer provide information about the actual installation status if the component has already been concealed during installation. Experts therefore recommend systematically recording the declarations as part of the construction site documentation and linking them to delivery notes, batch designations, and installation dates.
Content and Structure: What Must the Fire Protection Declaration of Conformity Contain?
A complete Declaration of Conformity for Fire Protection contains a series of mandatory details derived from the respective state building codes and the requirements of the underlying performance certificates. Essential components include the exact designation of the construction product or construction type, including the type designation, batch or serial number, and manufacturer information. Furthermore, a reference must be made to the regulatory framework, approval, or test certificate on the basis of which conformity is declared. This reference must be unambiguous: The abZ number, the date of the test certificate, or the standard designation must be clearly stated.
In addition, the declaration specifies the specific fire protection properties for which conformity applies. These may include fire resistance classes according to DIN EN 13501, such as REI 90 (load-bearing and compartment-sealing function, 90 minutes of fire resistance) or EI 60 (compartment-sealing, 60 minutes), but also building material classes according to DIN 4102 or European fire behavior classes according to EN 13501-1, such as A1, A2, B, C, D, E, or F. The declaration must also specify the installation conditions under which compliance applies, as many approvals are tied to specific installation details: connection designs, fastening spacings, joint designs, or minimum thicknesses.
Formally, the declaration must be signed by an authorized signatory from the manufacturer or the contracting company, including the date, location, and company name. Some state building codes additionally require the location of use to be specified, i.e., the specific construction project. This requirement is sensible because it ties the declaration to a specific project and facilitates later attribution in the event of damage. In practice, it is recommended to maintain a structured filing system for all declarations of conformity within the construction documentation, organized by trade and component, with cross-references to plans and bills of quantities.
Classification Reports and Test Certificates as a Basis
The content of the declaration of conformity is based on classification reports and test certificates issued by accredited testing laboratories. A classification report in accordance with DIN EN 13501 summarizes the results of fire tests and derives the fire resistance class from them. It is not a public document but rather the property of the manufacturer, who uses it as the basis for their Declaration of Conformity. Inspectors and fire protection engineers may request to see the classification report in order to verify the information contained in the Declaration of Conformity. Any planner or construction manager who accepts declarations of conformity without occasionally reviewing the underlying test documents is relinquishing a significant part of quality assurance.
Common Mistakes in Practice and How to Avoid Them
The most common deficiencies in fire protection declarations of conformity relate to four areas: missing declarations, declarations with incomplete content, declarations for the wrong products, and declarations that do not correspond to the actual installation. Missing declarations usually result from a lack of coordination between the supplier and the contractor: The product is delivered and installed, but the declaration arrives later—or not at all. This can be remedied by a contractual provision that defines the submission of the declaration of conformity as an integral part of the delivery.
Declarations that are incomplete in content often lack a batch designation, a reference to the specific construction project, or a specification of the installation conditions. The absence of installation conditions is particularly critical: A fire damper approved for a specific mounting frame and a specific duct layout loses its classification if it is installed differently. The declaration of conformity that does not specify this deviation is then technically incorrect, even if it appears formally complete.
Declarations for incorrect products arise when a manufacturer issues a model declaration of conformity for a product family without specifying the specific variant that was delivered. Fire protection products often come in numerous variants with different classifications, and a blanket declaration for “all products in the X series” is insufficient under building codes. Finally, discrepancies between the declaration and the actual installation arise when products are replaced at short notice on the construction site without updating the documentation. This scenario is more common in practice than one might assume and requires consistent supplementary documentation.
To avoid these errors, fire protection experts recommend the following measures:
- Early inclusion of requirements for declarations of conformity in specifications and contracts for work
- Systematic recording of all fire protection-relevant construction products in a product list with links to certificates of suitability
- Random spot checks of the declarations by the fire protection planner or construction manager during construction
- Documentation of product substitutions with corresponding updates to the declarations of conformity
- Retention of all declarations in the construction documentation for at least the duration of the warranty period, preferably for the entire service life of the building
The Declaration of Conformity within the Overall System of Structural Fire Protection Documentation
A building’s structural fire protection is not ensured by a single document, but rather by a system of interlocking verifications, tests, and declarations. The process begins with the fire protection concept, which is prepared by a qualified fire protection specialist and describes the building’s protection-objective-oriented requirements: protecting human life, limiting the spread of fire, and enabling effective fire-extinguishing measures. The fire protection concept specifies which building components must meet which fire resistance classes, which materials may have which fire behavior classes, and which systems—such as fire compartments, fire doors, or smoke exhaust systems—must be provided.
The Declaration of Conformity for Fire Protection is the instrument that ensures the properties required in the fire protection concept are actually present in the completed construction. It bridges the gap between planning and execution. Without it, the fire protection concept remains a theoretical document that provides no indication of the actual conditions of the completed building. In this sense, the Declaration of Conformity is the construction-side counterpart to the fire protection verification on the design side.
As part of the building inspection, the building authority or a commissioned expert verifies whether the essential fire protection requirements have been met. The submission of the Declarations of Conformity is a central element of the supporting documentation. In buildings classified as Classes 4 and 5 under the Model Building Code—that is, in multi-story residential buildings and special-purpose structures—the completeness of this documentation is generally a prerequisite for occupancy approval. If a declaration is missing for a safety-critical building component, approval may be denied until the required evidence is provided.
The fire safety declaration of conformity is of particular importance for special-purpose buildings: hospitals, schools, places of assembly, high-rise buildings, and industrial structures are subject to specific special-purpose building regulations that go beyond the general requirements of state building codes. Here, the chain of evidence is particularly complex because, in addition to general product requirements, specific system requirements must also be met. A fire-separation system in a hospital must not only be classified on its own, but must also have a valid classification in the specific combination of wall construction, pipe type, and fire-separation product. The Declaration of Conformity must explicitly specify this system combination.
Fire Safety Verification as an Ongoing Task: Operation, Renovation, and Documentation
The relevance of the fire protection declaration of conformity does not end with the completion of a building. In the event of renovations, changes in use, or repair measures that affect fire protection-relevant building components, new declarations of conformity are required for the products and construction types used. A common problem in practice is that, during renovation work, the existing fire protection documentation is either unknown or unavailable, making it impossible to assess the conformity of the new components with the overall system. This problem underscores the importance of complete construction documentation throughout a building’s entire life cycle.
Facility managers and building operators are well advised to permanently archive the declarations of conformity as part of the building documentation and to use them as a reference document during renovation projects. In digital building models (Building Information Modeling, BIM), declarations of conformity can be stored as attributes of individual building components and automatically flagged as requiring review when changes are made. This capability is still underutilized in practice, even though it would significantly simplify quality assurance in fire protection.
The fire safety declaration of conformity marks the end of a chain of decisions that begins with planning and ends with construction. It is the document that closes this chain and verifies that the path from requirement to reality has indeed been completed. Those who understand, use, and consistently require this tool not only contribute to the legal safeguarding of the construction project but also to the safety of the people who will use the building. That is the true standard by which every fire safety verification document should be measured.
