Švariosios patalpos ir su jomis susijusi kontroliuojamoji aplinka. 15 dalis. Įrangos ir medžiagų tinkamumo naudoti vertinimas pagal ore sklindančių cheminių medžiagų koncentraciją (ISO/FDIS 14644-15:2025)

ISO 14644-15:2017 provides requirements and guidelines for assessing the chemical airborne cleanliness of equipment and materials which are foreseen to be used in cleanrooms and associated controlled environments which are linked to the ISO standard for cleanliness classes by chemical concentration (see ISO 14644‑8). The following are outside the scope of ISO 14644-15:2017: - health and safety requirements; - compatibility with cleaning agents and techniques; - cleanability; - biocontamination; - specific requirements of equipment and materials for processes and products; - design details of equipment.

Švariosios patalpos ir su jomis susijusi kontroliuojamoji aplinka. 13 dalis. Paviršių valymas nustatytam švarumo lygiui pagal dalelių ir cheminių medžiagų koncentracijos klasifikacijas pasiekti (ISO/FDIS 14644-13:2025)

ISO 14644-13:2017 gives guidelines for cleaning to a specified degree on cleanroom surfaces, surfaces of equipment in a cleanroom and surfaces of materials in a cleanroom. Under consideration are all surfaces (external or internal) that are of interest. It provides guidance on the assessment of cleaning methods for achieving the required surface cleanliness by particle concentration (SCP) and surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels. The appropriateness of cleaning techniques will make reference to the cleanliness classes and associated test methods found in ISO 14644‑9 and ISO 14644‑10. The following matters of general guidance will be provided: - expected surface cleanliness levels; - suitability of cleaning methods; - compatibility of surfaces with the cleaning technique; - assessment of cleaning appropriateness. The following will be excluded from this document: - classification of cleaning methods; - product produced within a cleanroom; - specific surface-related cleaning methods; - detailed description of cleaning mechanisms, methods and procedures of various cleaning methods; - detailed material characteristics; - description of damage mechanisms by cleaning processes and time-dependent effects; - references to interactive bonding forces between contaminants and surfaces or generation processes that are usually time-dependent and process-dependent; - other characteristics of particles such as electrostatic charge, ionic charges, etc.; - chemical reactions between molecular contaminants and surfaces; - microbiological aspects of surface cleanliness; - radioactive aspects of contamination; - health and safety considerations; - environmental aspects such as waste disposal, emissions, etc.; - selection and use of statistical methods.

Švariosios patalpos ir su jomis susijusi kontroliuojamoji aplinka. 14 dalis. Įrangos tinkamumo naudoti vertinimas pagal ore sklindančių dalelių koncentraciją (ISO/FDIS 14644-14:2025)

ISO 14644-14:2016 specifies a methodology to assess the suitability of equipment (e.g. machinery, measuring equipment, process equipment, components and tools) for use in cleanrooms and associated controlled environments, with respect to airborne particle cleanliness as specified in ISO 14644‑1. Particle sizes range from 0,1 µm to equal to or larger than 5 µm (given in ISO 14644‑1). NOTE Where regulatory agencies impose supplementary guidelines or restrictions, appropriate adaptation of the assessment methodology can be required. The following items are not covered by this ISO 14644-14:2016: - assessment of suitability with respect to biocontamination; - testing for suitability of decontamination agents and techniques; - cleanability of equipment and materials; - requirements on design of equipment and selection of materials; - physical properties of materials (e.g. electrostatic, thermal properties); - optimizing performance of equipment for specific process applications; - selection and use of statistical methods for testing; - protocols and requirements for local safety regulations.
