Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for air-purification performance of semiconducting photocatalytic materials - Removal of methyl mercaptan has-corrigendum The established principles and methods

The established principles and methods are basic for all document management systems

BS EN 60118-8 specifies tolerances and conformance to its specifications is demonstrated only when the result of a measurement

and is as follows:

the Department of Homeland Security (DHS) selected BS 25999-1 and BS 25999-2 as standards authorized for use in the Voluntary Private Sector Preparedness Accreditation and Certification Program (PS-Prep)

Fine ceramics (advanced ceramics, advanced technical ceramics). Test method for air-purification performance of semiconducting photocatalytic materials - Removal of methyl mercaptan has-corrigendum The established principles and methods1 Scope This part of ISO 22197 specifies a test method for the determination of the air purification performance of materials that contain a photocatalyst or have photocatalytic films on the surface, usually made from semiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under illumination with ultraviolet light (UV A). This part of ISO 22197 is intended for
