JSA JIS R 1701-1

Abstract

Scope: This Standard specifies the method to test the removal performance of nitric oxides [NOx, total of nitrogen monoxide (NO) and nitrogen dioxide (N02)], among air purification performances, of the photocatalytic materials supported on the surface of building materials and other products. This Standard is mainly intended for photocatalysts which are effective in ultraviolet (UV) region within a wavelength range of 300 nm to 380 nm, under solar radiation. To the testing of NOx removal performance under visible light, the method given in JIS R 1751-1 shall be applied instead of the method specified in this Standard. NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. ISO 22197-1: 2007 Fine ceramics (advanced ceramics, advanced technical ceramics)-Test method for air-purification performance of semiconducting photocatalytic materials-Part 1: Removal of nitric oxide (MOD) In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
