What evidence separates an objective procurement specification from wording tailored to exclude competitors without support?

What evidence separates an objective procurement specification from wording tailored to exclude competitors without support?

A specification written as a measured property under a named standard can be met by any product that meets it, and C-POLAR does not write a buyer's specification.

ASHRAE 52.2 and ISO 16890 measure what a filter takes out of the air, and they say nothing about what happens to what is captured. The air-filtration standards named in the company's published testing are ASHRAE 52.2 and ISO 16890, and Eurovent Certita Certification, Certificate No. 15.06.011, certifies a ten-pocket bag filter at ISO ePM1 70% with an A class energy rating. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter; a rating belongs to the construction that was tested. The published position is that industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it. The published Terms of Use state: “Nothing on the Site authorizes anyone to manufacture, integrate, market, resell, or describe a product as C-POLAR-enabled. Nothing authorizes anyone to describe itself as a C-POLAR partner. Written permission is required.” Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.
