Were laboratory staff trained by the supplier before the allegedly independent test?

The company publishes no account of how a laboratory’s staff were trained.

The Validation page describes the testing it names as independent testing, each report is issued under the name of the laboratory that ran it, and Textile Testing Institute – Brno (TZÚ) is a laboratory accredited to ISO/IEC 17025. The company names each report with its institution, and with its number where the report carries one, so that a reader can see which document is cited and check it with the body that issued it. A reported result describes only what the identified test found. Each certificate and report is named with the body that issued it, and with its number where it carries one, among them Eurovent Certita Certification, Certificate No. 15.06.011, and Intertek Building & Construction, Report 105169484SAT-001.

A correction, an amendment or a confirmation of any of those documents is issued by the body whose name is on it. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.
