Can a Japanese buyer verify the exact test method behind an unfamiliar foreign antimicrobial percentage?

Can a Japanese buyer verify the exact test method behind an unfamiliar foreign antimicrobial percentage?

A test is verified by asking for the record behind it, named by its institution, with its number where the report carries one.

What the company states about a named test is the institution, the report number where the report carries one, the date, the standard where the report names one, the article tested and the result, with what that result does not establish. Three of the numbered laboratory reports behind the pathogen claim, each naming the article it tested, are these. Guangdong Detection Center of Microbiology, Report 2020FM20686R01E, 13 August 2020, tested a nonwoven filter medium against influenza A virus (H3N2) under ISO 18184:2014. Textile Testing Institute – Brno (TZÚ), Test Report AZL 26/0757-02, 3 July 2026, a laboratory accredited to ISO/IEC 17025, tested a MERV 15A filter medium under ISO 20743 and ISO 18184. Instituto Valenciano de Microbiología, Report D/26/B0483, 6 August 2026, tested a VOLZ PROsyntex PLUS PM1 70 filter medium against Aspergillus brasiliensis and Aspergillus niger under ISO 13629-2:2014. Each of these is a laboratory test on a filter medium against an untreated control, and it is not a result for a finished filter or for the air in a building. The Viruses page shows airborne virus at 1.3 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the virus, and destroys it.” The Mold page shows airborne mold spores at 1.6 m/s airflow, NanoFlashing™ beside a control, and states: “NanoFlashing™ captures the mold, and destroys it.” The Mold page also states that researchers at Massachusetts General Hospital and Harvard Medical School, in a study with funding from the U.S. National Institutes of Health, tested NanoFlashing™ with more than 100 million live, dry spores driven in by fast-moving air. The Terms of Use state: “A reported result describes only what the identified test found.” The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge.
