The 2025
Manufacturers

Each manufacturer shown here submitted unique bills of materials (BOMs) for testing in Kiwa PVEL’s Product Qualification Program (PQP). These BOMs are represented by their associated model types in the 2025 Top Performer searchable database. The manufacturer logos are separated by the number of PQP tests for which that manufacturer has one or more models listed as a Top Performer, then shown in alphabetical order by the manufacturers’ number of Scorecard appearances. The applicable test icons are shown under each logo. Click on the logos to see the Top Performer model types from that manufacturer or click on the test icons to learn more about that test.
