PVC-free printing media and B1-certified materials are two different requirements that often occur together in object planning. PVC-free describes the chemical composition of a material and is relevant for sustainability and health requirements. B1 is a fire safety classification according to DIN 4102 and describes the fire behavior of a material. This article answers questions about when which certificates apply, which combinations are possible, and what this means for tenders.
What distinguishes PVC-free printing media from conventional materials?
PVC-free printing media completely dispense with polyvinyl chloride as the carrier material. Conventional large-format printing media often rely on PVC films, which are cost-effective and versatile but can release problematic substances during production, processing, and disposal. PVC-free alternatives consist of materials such as polyester, polypropylene, paper, or textile carriers.
The practical difference is evident primarily in three areas:
- Environmental compatibility: PVC-free materials do not contain chlorine compounds And they are usually easier to recycle or compost. They do not release hydrochloric acid during combustion, which is relevant both for the environment and for health in the workplace.
- Indoor air quality: PVC films often contain plasticizers (phthalates) that can be released into the air. In enclosed spaces such as hotel rooms, offices, or retail spaces, this is a relevant factor, especially when certifications such as LEED or BREEAM are being pursued.
- Printing technical characteristics: PVC-free materials behave differently in printing depending on the substrate. They require coordinated ink systems and printing parameters, but when properly configured, they provide equivalent or better printing results.
For building planners, this means that PVC-free is not a quality characteristic in the strict sense; rather, it is a material choice with consequences for sustainability, certification, and the room climate.
What exactly does the B1 certification mean for printing materials?
B1 is a fire protection classification according to the German standard DIN 4102 and stands for „highly flammable“. A B1-certified pressure medium does not ignite on its own under defined test conditions and does not contribute to the spread of fire. The testing is carried out by accredited testing institutes; the result is documented in a testing certificate.
The standard DIN 4102 distinguishes several classes:
- B1 (highly flammable): The material does not ignite on its own and extinguishes after removing the ignition source. This is the relevant class for most object applications.
- B2 (normally flammable): Corresponds to the standard behavior of most untreated materials.
- B3 (slightly flammable): Not approved for use in public or commercial buildings.
In parallel, the European standard EN 13501-1 exists with Euro classes A1 to F. In many current tenders, both systems are mentioned; however, in Germany, B1 according to DIN 4102 still serves as the reference. Important: The B1 certification always applies to the finished product, i.e., the printed or unprinted material in its final form. Subsequent treatment with flame retardants can change the classification and must be separately proven.
When is B1-certified material required in building projects?
B1-certified materials are required throughout Germany wherever the state building codes or specific special building regulations impose increased fire protection requirements. In practice, this applies to almost all publicly accessible buildings and many commercial areas.
Typical application areas requiring B1:
- Hotels and accommodation establishments with a certain number of beds or a certain building class
- Retail trade and shopping centers with increased pedestrian traffic
- Office buildings with more than a certain amount of usable space or number of people
- Corridors, stairwells and escape routes in almost all commercial buildings
- Trade fair and event spaces
- Hospitals, schools and public facilities
The exact requirements vary depending on the state, building class, and use of the facility. The relevant state building regulations, the Muster-Versammlungsstättenverordnung (MVStättVO) and the Muster-Beherbergungsstättenverordnung (MBeVO), are the governing factors. Property planners should clarify the fire protection requirements early in the project, as any subsequent material changes are time-consuming and costly.
What proof do suppliers have to provide for PVC-free and B1 materials?
For PVC-free materials, tenders and sustainability certifications usually require a material declaration or a safety data sheet that confirms the composition of the carrier material. For B1 classification, a valid test certificate from an accredited testing institute in accordance with DIN 4102 or EN 13501-1 is required.
In particular, suppliers should be able to provide the following documents:
- Certificate of competence B1: Issued by an accredited institute such as MPA, DEKRA or TÜV. The certificate must clearly identify the tested product and must not be expired.
- Material declaration or safety data sheet: It certifies the composition of the material and the absence of PVC.
- Product data sheet: Contains technical specifications, pressure compatibility, and application recommendations.
- Manufacturer compliance declaration: In some projects, a written declaration from the manufacturer is also required that the material delivered corresponds to the tested sample.
Please note that test certificates are product-specific. A B1 certificate for a specific material does not automatically apply to other products of the same manufacturer. For projects with official approval, it is recommended to secure the proof of compliance before ordering.
Can PVC-free printing media be B1 certified at the same time?
Yes, PVC-free printing media can be B1 certified at the same time. The two requirements do not conflict because they describe different properties of a material. PVC-free refers to the chemical composition, while B1 refers to fire resistance. Many modern printing media based on polyester or polypropylene meet both criteria.
However, the combination is not automatic. Not every PVC-free material is automatically flame-retardant, and not every B1 material is PVC-free. For project applications that meet both requirements, materials must be selected specifically and the corresponding certifications must be obtained separately.
In practice, there is today a growing selection of materials that combine both properties. Textile-based printing media, certain polyester films, and special vinyl wallpaper are examples where PVC-free and B1 certification are available in combination. However, availability depends heavily on the specific product type and the respective manufacturer. Always ask for both certificates separately, even if a supplier claims both properties for a product.
How do these certificates affect tenders and project costs?
B1-certified and PVC-free materials generally cost more than standard materials without these features. The price difference varies depending on the material type, but is often 20 to 50 percent higher than the price of comparable standard products. For tenders, this means a higher material calculation that should be planned early on.
The following practical consequences arise for the design of the tender:
- Description of duties: Material requirements such as „B1 according to DIN 4102“ or „PVC-free with material declaration“ must be explicitly included in the performance description so that all bidders can calculate on the same basis.
- Obligation to provide evidence: Tenders should specify which documents must be submitted with the offer or at the latest upon delivery. Missing proofs can lead to the rejection of a delivery.
- Product alternatives: If no equivalence is allowed, this restricts the range of suppliers and can increase prices. A functional tender that describes characteristics rather than products creates more competition.
- Long-term costs: PVC-free materials can reduce subsequent costs associated with disposal or demolition, which is relevant when considering overall costs.
For sustainability certifications of the building (LEED, BREEAM, DGNB), PVC-free materials can earn points that justify the additional cost in the overall project. Be sure to clarify with the developer early on what certification goals exist so that the material selection is aligned with them from the outset.
