Independent Corporation Tests

Sapa Logo Indalex Logo

Independent Secondary Protective Clothing tests conducted by Indalloy Toronto Division, Ontario, Canada (a subsidiary of Sapa Group of Sweden), found as follows -

  • A stand was set up consisting of a thin painted steel sheet angled at 65° and running into a steel pit sow.

  • For the run-off tests the sample was draped over the steel sheet and approximately .5 kg of molten aluminium at approximately 1350° F (732° C) was poured over it.
