Cleanrooms are about much more than just cleanliness.
This is where highly sensitive products such as pharmaceuticals, implants, diagnostic systems, and microelectronic components are developed, manufactured, and processed.
In cleanrooms, contamination is controlled to protect sensitive products, processes, and research results. Particle emissions, cleanability, and the durability of the surfaces used have a direct impact on the cleanliness of the environment.
Purity requirements are defined by the DIN EN ISO 14644 standard. It classifies cleanrooms into ISO classes 1 through 9 based on the permissible particle concentration. The lower the ISO class, the higher the air purity requirements.
In addition, the EU GMP guidelines apply to the manufacture of pharmaceuticals; these guidelines take into account not only particles but also microbiological contamination. GMP class A corresponds approximately to an ISO class 5 cleanroom.
The cleanroom suitability of materials is evaluated based on various criteria as part of the Fraunhofer IPA’s CSM® (Cleanroom Suitable Materials) program.
These criteria include particle emission, chemical and biological resistance, the cleanability of surfaces, and behavior during H₂O₂ decontamination processes. The test methods are based on recognized standards and guidelines and enable an objective assessment of materials’ suitability for contamination-critical environments.
Certified cleanroom compatibility for sensitive production, laboratory, and hygiene areas.

Proven cleanroom suitability combined with conductive properties for ESD-sensitive areas.
Zum Produkt
The number of particles released by mechanical stress on the floor and their size distribution are determined.
→ The particles emitted by VIASOL systems do not compromise the air purity of an ISO 5 cleanroom.
Resistance to a group of representative cleaning agents and disinfectants is tested.
→ The coating exhibits very good resistance to cleaning agents and disinfectants.
The test determines whether bacteria and fungi can colonize or degrade the material.
This test evaluates how effectively a contaminated surface can be cleaned after three wipe-cleaning cycles. The material surface plays an important role in this process.
→ The contamination can be removed very easily.
The time elapsed until the H2O2 concentration has dropped to one-tenth of its initial value is measured.
→ The VIASOL DESIGN QCV conductive is classified as “non-absorptive” with a decay time of < 5 min. H2O2 is practically not absorbed and is released again very quickly after ventilation. With a value of > 15 to ≤ 60 min, the VIASOL DESIGN QCV achieves the “medium” classification.
