INDEPENDENT TESTING
Metalife’s tradition of high quality is backed up by independent testing and the results of those tests.  We hope these results prove informative and helpful in your decision to try a Metalife coating.  Please contact us if you would like a copy of the actual report for the results described below.
COMPLIANCE RESULTS FOR OSHA’S NEW STANDARD FOR HEXAVALENT CHROME
AREA PARAMETER METHODOLOGY DATE MINUTES LPM FLOWRATE TOTAL LITERS RESULTS OSHA PEL LIMIT
Tank Operator Hexavalent Chromium OSHA 215-2 6/4/2015 421 2.0 842 .45 μg/m3 5.0 μg/m3
Procedure for RoHS Compliance Test:
Hexavalent chromium was analyzed via boiling water leach procedure outlined in Delphi DX900359. Cadmium and lead were determined via flame atomic absorption. Mercury was determined via cold vapor atomic absorption. Coating weight was determined via weigh-strip-weigh using antimony trioxide inhibited hydrochloric acid.

Conclusion:
“The overall results for the Metalife coated samples show a considerable increase in PV limit when compared to previous tests run on uncoated samples.  Similar comparisons to uncoated wear tests indicate that the wear rate was reduced significantly when coated with the Metalife system.”
