scope:

This Standard specifies a test method for evaluating antialgal activities in outdoor structures, specifically flat photocatalytic materials (for example, exterior wall materials, tents, window panes and water tank glasses, films, guardrails, etc.) under irradiation of ultraviolet (UV) light. It does not include powder, granular or porous photocatalytic materials.

WARNING Persons carrying out tests based on this Standard should acquire microbiological techniques.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 19635 : 2016 Fine ceramics (advanced ceramics, advanced technical ceramics) - Test method for antialgal activity of semiconducting photocatalytic materials (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/IEC Guide 21-1.
