Tiled, Seamless, Raised Access and Epoxy Resin Systems
Cleanroom flooring systems, appropriately designed and installed, serve to mitigate electrostatic charges, microbial bioburden and maintenance requirements. They offer high quality and consistent performance. Matching welding, skirting and coving assemblies, integrated into the installation, ensure system solutions for demanding floors in cleanroom and high tech environments. They should be specified from non shedding, low VOC outgassing, and durable material with smooth high gloss finishes to repel particulate entrapment and avoid shredding cleanroom type shoe covers.
Raised tile access flooring systems provide for conditioned air delivery under the equipment, support heavy equipment, and provide easy access to the electrical services raceways. A raised access flooring systems is particularly functional to speed up maintenance activities and later alterations to the cabling and connections thanks to the dry removability of the system components, with no need for under the floor actions required while making them effective. The need for new cabling is increasingly more frequent due to the technological development of work instruments and data transmission networks, especially in cleanroom environments. The flexibility of a raised access floor makes this installation work extremely easy. More in general, the raised flooring system enables conditioned air, process gases and liquids, and utility chases to be renovated and rerouted with minimum disruption to the facility.
Cleanroom Flooring Systems:
The selection of a cleanroom flooring system is particularly important because of its greater susceptibility to contamination compared to ceiling and walls. Particulate entrapment on flooring systems can quickly be infused into the air handling system through low level returns to cause premature loading of expensive HEPA filtration systems. Depending on design and use, clean room flooring can have a variety of features: electrostatic dissipative qualities; permanent tackiness to remove dirt particles from the underside of footwear; biocides to help control microbial growth within the flooring; and resistance to damage from certain kinds of spilled chemicals. Floor surfaces can be made of vinyl, high pressure laminate, poured polymers, metal, and even certain kinds of paint coatings. All cleanroom flooring system finishes should be smooth and homogeneous in nature unless utilizing perforated steel or aluminum raised access floor panels for laminar airflow circulation.
ISO 846 / 2812-1 Standards:
Several cleanroom flooring manufacturers have had product tested under ISO 846 - Determination of behavior under the action of fungi and bacteria. ISO 846 or ISO 846:1978 test method is used to evaluate deterioration of a material by fungi, or bacteria. This test proves that the material is not a nutrient for micro-organisms and that it is therefore inert and fungistatic. The chemical resistance is tested to comply with ISO 2812-1. The selected chemicals are those mostly present in surface cleaning agents, disinfecting products and bio-decontamination procedures. Emissions of TVOC at 23° C should not exceed the limiting values for ISO-AMC Class -9.1 according to ISO 14644-8.
