Which named institutions actually performed the cited work, and which appear only in a method reference, publication or credential?

The Validation page keeps two lists apart, and each says a different thing.

Under Pathogens it names the institutes that tested NanoFlashing™: Harvard Medical School, Massachusetts General Hospital, University of Minnesota, Czech Academy of Sciences, Textile Testing Institute - Brno, Czech Republic, Tampere University, Finland, Instituto Valenciano de Microbiologia, Hong Kong Metropolitan University, The Open University of Hong Kong, and Guangdong Detection Center of Microbiology. Under Peer-Reviewed it lists the affiliations of the authors of Gong, Or, Sze et al., Microbiology Spectrum 12(9), e0409723, American Society for Microbiology, September 2024, doi 10.1128/spectrum.04097-23.

An affiliation on a paper is where an author works, and it is not a statement that the institution performed a test. The work of the named institutes is cited as follows. 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. Guangdong Detection Center of Microbiology, Report 2020FM20686R01E, 13 August 2020, tested a nonwoven filter medium against influenza A virus (H3N2) under ISO 18184:2014. The Open University of Hong Kong, Test Report IRITS2020007030001R1, 7 June 2021, measured bacterial filtration efficiency on a spunlace nonwoven by a method modified from ASTM F2101:2019, after accelerated ageing to ASTM F1980-16 equivalent to five years at room temperature. Hong Kong Metropolitan University is the same institute, renamed. Tampere University, Department of Virology, report dated 1 April 2021, tested a treated material against human coronavirus 229E and Coxsackievirus B6. Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences, report dated 29 April 2021, tested a treated material under ISO 18184. For Harvard Medical School, Massachusetts General Hospital and the University of Minnesota, the published record is the peer-reviewed paper. The paper reports laboratory results on SARS-CoV-2 in contact with treated textile, on aerosolised bovine coronavirus passed through a test filter in a wind tunnel, and on bacterial viability on treated textiles; each result belongs to the article that was tested. An institution’s name is not a result: what a named test found is stated with the article, and with the standard and the report number where the report carries them, and each report describes only the article it names.
