CC Matting Heavy Duty: when the transfer point needs ISO Class 5 material documentation
In cleanrooms and controlled environments, an entrance mat can become the point where you reduce particle transfer from soles and light wheels, with a clear cleaning routine and documentation the quality team can use.
When documentation changes the matting decision
At a transfer point into a clean area, the difference is not only colour or mat size. What matters is the traffic crossing the surface, which particles can be transferred, how the mat is cleaned and which documents help the team during selection, validation or audit.
For many teams, peel-off adhesive mats have been the simple option. But when the point is permanent, traffic is steady and the area needs clearer documentation, reusable polymer matting can become the more stable direction.
The CC Matting Heavy Duty polymer contamination-control mat helps when the team needs a washable mat with documented material, available tests and instructions that fit the site procedure.
What the CC Matting technical file adds to selection
Particles and fibres
The CCM Heavy Duty test report indicates removal efficiencies above 90% for the three categories analysed.
2.9 mm thickness
The technical data sheet lists 2.9 mm thickness and 3.3 kg/m2 weight, useful for installation, edges, traffic and cleaning.
Where ISO Class 5 meets EU GMP Grade A-D
ISO 14644-1 and EU GMP Annex 1 are different frameworks, but they meet in areas where air, surfaces, people, materials and mobile equipment need to be controlled together.
ISO 14644-1: airborne particles
ISO 14644-1 classifies air cleanliness by airborne particle concentration in cleanrooms and clean zones. It is the language teams use when they discuss ISO Class 5, ISO Class 7 or ISO Class 8.
For CC Matting Heavy Duty, the Fraunhofer IPA certificate refers to the material: CCM HD Polymeric Matting solid grey was tested for particle emission and indicated as suitable for Air Cleanliness Class ISO Class 5 under the test conditions.
- useful for material selection in clean areas;
- relevant around soles, light wheels, trolleys and transfer points;
- read together with positioning, cleaning and operator monitoring.
EU GMP Annex 1: grades, operating state and CCS
In sterile pharma, EU GMP Annex 1 works with Grade A, B, C and D, plus “at rest” and “in operation” states. Grade A is the critical zone for high-risk operations; Grade B is usually the background for Grade A in aseptic manufacturing; Grade C and D support less critical stages.
In practice, Grade A and Grade B “at rest” use ISO 5-equivalent particle levels for ≥0.5 µm. In operation, Grade A remains ISO 5, Grade B corresponds to ISO 7, Grade C to ISO 8, while Grade D in-operation limits are set through risk assessment and routine data.
- the CC Matting point becomes relevant in transitions, airlocks, gowning or material-transfer points;
- for direct Grade A use, the decision belongs with quality, validation and the contamination-control strategy;
- the mat supports floor-level control; room classification remains within the operator procedure.
Where the material matters, not only the mat format
A good controlled point connects three things: available material documentation, real traffic and the routine that keeps the surface clean.
Documented material for demanding areas
The Fraunhofer IPA certificate for CCM HD Polymeric Matting solid grey indicates suitability for Air Cleanliness Class ISO Class 5 based on particle emission testing of the material.
For the buyer, this moves selection toward verifiable criteria: tested material, available documentation and a clear link with the clean-area requirement.
- material certified for ISO Class 5 under test conditions;
- document verifiable through the certificate system;
- useful for quality, validation and material selection.
Soles, trolleys and light wheels between zones
The particle removal report analysed particles collected from warehouse flooring and transferred through shoe soles and trolley wheels. The result is useful for areas where light traffic crosses straight over the surface.
Selection still depends on the application: number of steps, wheel rotations, bypass, load, wheel material and cleaning frequency all change site behaviour.
- personnel entering a controlled area;
- trolleys, carts and light mobile containers;
- straight crossings without aggressive turns on the surface.
Cleaning, material conformity and site routine
CC Matting Heavy Duty comes with useful selection documents: CE/DoP, RoHS/SVHC, material information, cleaning instructions and antistatic data, depending on the file required.
In practice, the advantage appears only when the surface is cleaned correctly and the area owner knows when the mat returns to service. Documentation helps; the site routine makes the difference.
- cleaning integrated into the area procedure;
- edges, seams and easy access to the surface;
- documents kept with the internal procedure.
How to connect certification with the real application
ISO Class 5 material is a strong reference when certification is connected with the real area, traffic, installation, cleaning and operator verification.
What the certificate says
The Fraunhofer IPA certificate names CCM HD Polymeric Matting, solid grey vs. PA6 material pairing, reel-on-disc test with 300 N normal force and suitability for Air Cleanliness Class ISO Class 5.
This is a clear material argument. Room classification is established through the operator procedure, monitoring and validation.
What the removal test shows
The particle removal test looked at particles >5 um, particles >100 um and fibres >100 um, transferred through shoe sole and trolley wheel, then counted microscopically.
The report conclusion indicates efficiencies above 90% for the three tested categories. In quotation, the number should travel with the test conditions and the way the point will be cleaned on site.
What the real application decides
A clean area may include airlocks, gowning, air showers, pass-throughs, HEPA or GMP procedures. Polymer matting complements control at floor level, on the route of soles and light wheels.
Before quotation, a few practical details should be clear.
- where the transfer point sits and whether it can be bypassed;
- traffic type: personnel, trolleys, light wheels, mobile containers;
- targeted contamination: dust, visible particles, fibres or transfer between areas;
- documentation need: ISO Class 5, quality, validation, CE/DoP, RoHS/SVHC;
- who cleans the surface, how often and under which procedure.

Useful questions about CC Matting, ISO Class 5 and controlled areas
Decision points for quality, validation, facility and production when polymer matting must be selected by material, traffic and procedure.
For CCM Heavy Duty, ISO Class 5 refers to the tested material and Fraunhofer IPA certification for Air Cleanliness Class ISO Class 5. It is important information for material selection in clean areas.
- room classification is established through the operator procedure;
- particle monitoring remains part of site control;
- the document can support the internal selection file for the transfer point.
For a project, the certificate should be read together with mat position, traffic, cleaning, edges and the operator procedure.
ISO 14644-1 classifies air by particles. EU GMP Annex 1 uses Grade A-D for sterile zones and adds the process context: at rest, in operation, monitoring, microbiology, gowning, flows, CCS and validation.
- Grade A and Grade B at rest correspond to ISO 5 particle levels for ≥0.5 µm;
- in operation, Grade A remains ISO 5, Grade B corresponds to ISO 7 and Grade C corresponds to ISO 8;
- Grade D has no predetermined in-operation limit in Annex 1; the operator sets it through risk assessment and routine data.
For CC Matting, the useful link is material selection at transfer points: ISO Class 5 material certification can support quality review, while final Grade A-D positioning remains part of the site procedure and contamination-control strategy.
The CCM Heavy Duty efficiency report tested particles >5 um, particles >100 um and fibres >100 um, transferred through shoe soles and trolley wheels. The conclusion indicates removal efficiencies above 90% for the three categories.
- method: particles from warehouse floor dirt, microscopic counting;
- tested traffic: shoe sole and trolley wheel;
- test cleaning: 70% isopropyl alcohol and cleanroom wipers.
In public copy and quotation, the number should stay connected to the test conditions. On site, the result depends on traffic, position, contamination load and real cleaning.
It makes sense at transfer points where quality, validation or the internal procedure needs more than a product description: cleanrooms, pharma, medical, electronics, clean packaging, labs or transfer zones between controlled environments.
- entries with soles and light wheels;
- permanent points where peel-off becomes a difficult consumable;
- areas where material documentation belongs in the internal file;
- routes where the surface can be cleaned by procedure.
The 2.9 mm thickness is relevant for installation, edges, light-wheel crossing, cleaning and floor integration. It is not only a technical number; it changes how the mat behaves at the transfer point.
In a project, thickness should be read together with width, length, thresholds, doors, bypass risk, traffic and cleaning method.
Product documentation helps the team select the material and explain it internally. The site procedure defines how it is cleaned, who checks the area, when action is taken and which data is retained.
- Quality: which documents should be attached;
- Facility: who cleans and how often;
- Production: how traffic crosses the surface;
- Validation: what should be monitored after installation.
For orientation, a short description of the real point is enough to start; a complete technical file is not required.
- photos from both directions of the crossing;
- available dimensions and thresholds;
- traffic type: personnel, trolleys, light wheels, mobile containers;
- documents required by quality or validation;
- current cleaning routine and traffic frequency.
With this, the direction can be clarified: CC Matting Heavy Duty, application test, combination with another measure or active route cleaning.
